How To Setup Elasticsearch 6.4 On RHEL/CentOS 6/7?

What is Elasticsearch? Elasticsearch is a search engine based on Lucene. It is useful in a distributed environment and helps in a multitenant-capable full-text search engine. While you query something from Elasticsearch it will provide you with an HTTP web interface and schema-free JSON documents. it provides the ability for full-text search. Elasticsearch is developed in Java and is released as open-source under the terms of the Apache 2 license. Scenario: 1. Server IP: 192.168.56.101 2. Elasticsearch: Version 6.4 3. OS: CentOS 7.5 4. RAM: 4 GB Note: If you are a SUDO user then prefix every command with sudo, like #sudo ifconfig With the help of this guide, you will be able to set up Elasticsearch single-node clusters on CentOS, Red Hat, and Fedora systems. Step 1: Install and Verify Java Java is the primary requirement for installing Elasticsearch. So, make sure you have Java installed on your system. # java -version openjdk version "1.8.0_181" OpenJDK Runtime Environment (build 1.8.0_181-b13) OpenJDK 64-Bit Server VM (build 25.181-b13, mixed mode) If you don’t have Java installed on your system, then run the below command # yum install java-1.8.0-openjdk Step 2: Setup Elasticsearch For this guide, I am downloading the latest Elasticsearch tar from its official website so follow the below step # wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.4.2.tar.gz # tar -xzf elasticsearch-6.4.2.tar.gz # tar -xzf elasticsearch-6.4.2.tar.gz # mv elasticsearch-6.4.2 /usr/local/elasticsearch Step 5: Permission and User We need a user for running elasticsearch (root is not recommended). # useradd elasticsearch # chown -R elasticsearch.elasticsearch /usr/local/elasticsearch/ Step 6: Setup Ulimits Now to get a Running system we need to make some changes of ulimits else we will get an error like “max number of threads for user is too low, increase to at least ” so to overcome this issue make below changes you should run. # ulimit -n 65536 # ulimit -u 2048 Or you may edit the file to make changes permanent # vim /etc/security/limits.conf elasticsearch - nofile 65536 elasticsearch soft nofile 64000 elasticsearch hard nofile 64000 elasticsearch hard nproc 4096 elasticsearch soft nproc 4096 Save files using :wq Step 7: Configure Elasticsearch Now make some configuration changes like cluster name or node name to make our single node cluster live. # cd /usr/local/elasticsearch/ Now, look for the below keywords in the file and change according to you need # vim conf/elasticsearch.yml cluster.name: kapendra-cluster-1 node.name: kapendra-node-1 http.port: 9200 to set this value to your IP or make it 0.0.0.0 ID needs to be accessible from anywhere from the network. Else put your IP of localhost network.host: 0.0.0.0 There is one more thing if you have any dedicated mount pint for data then change the value for #path.data: /path/to/data to your mount point.

Your configuration should look like the above. Step 8: Starting Elasticsearch Cluster As the Elasticsearch setup is completed. Let the start Elasticsearch cluster with elastic search user so first switch to elastic search user and then run the cluster # su - elasticsearch $ /usr/local/elasticsearch/bin/elasticsearch 22278 Step 9: Verify Setup You have all done it, just need to verify the setup. Elasticsearch works on port default port 9200, open your browser to point your server on port 9200, You will find something like the below output http://localhost:9200 or http://192.168.56.101:9200 at the end of this article, you have successfully set up Elasticsearch single node cluster. In the next few articles, we will try to cover a few commands and their setup in the docker container for development environments on local machines. Read the full article

Make sure to send Overwolf feedback saying you’ve uninstalled because of their company politics and genocide funding. I don’t think it’ll change anything, but hey, why not.

I’ve personally downloaded Prism Launcher as an alternative - didn’t take me long at all, the only thing that gave me a bit of trouble was having to manually update my JDK.

🤲 have some links:

^^ Prism Launcher

^^ JDK (Java) 17 (i got 17 cause it’s the one my mods needed)

Overwolf (Who owns Curseforge) is an israeli company which is supporting the genocide in palestine and funding the IDF

Dont use curseforge anymore.

For downloading game mods: If it's Minecraft, use Modrinth instead, for any other games use gamebanana or nexusmods.

The original tweet appears to have been deleted. and im unable to find it on Archive.org, but the tweets are still indexed by google.

They're still openly raising money for Israel, though instead of the IDF in specific its just general "those affected by the Hamas attacks"

Understand the Oracle Java License Change and Maximize Savings with Oracle BYOL

In recent years, Oracle has made significant changes to how it licenses Java, a move that has caught many organizations off guard. The Oracle Java license change represents a strategic shift that affects how businesses access and use Java in their IT environments. At the same time, Oracle offers the Bring Your Own License (BYOL) model to help companies manage licensing costs while maintaining compliance. Understanding both the licensing changes and the BYOL model is crucial for IT leaders, developers, and procurement teams aiming to avoid unexpected costs and maintain operational efficiency.

Oracle Java License Change: What You Need to Know

Historically, Oracle provided Java under a free-to-use license model, primarily for personal and development purposes. However, starting in 2019, Oracle announced a new subscription-based model for commercial users of Oracle Java SE. Under this model, users are required to pay for updates, support, and the continued use of Java in production environments.

Then in 2023, Oracle made another update by introducing a new Java SE Universal Subscription, a per-employee license that bundles support for multiple versions and deployment types. This new subscription replaced the legacy per-processor or per-user pricing, and it now applies to all employees—not just developers or IT users. The goal was to simplify Java licensing, but for many organizations, it significantly increased costs and licensing complexity.

This Oracle Java license change has sparked widespread concern, especially among companies that were previously unaware of their licensing obligations or believed Java remained free for commercial use. Businesses now face the dual challenge of identifying where Java is deployed and determining whether those deployments fall under Oracle’s commercial licensing requirements.

The Risks of Non-Compliance

The Oracle Java license change means organizations must carefully audit their environments. Java is often deeply embedded in custom applications, middleware, and legacy systems. Without proper tracking, many businesses may be using Oracle Java without realizing they owe subscription fees. Oracle has been known to audit companies and impose hefty penalties for non-compliance.

Being proactive is essential. Organizations must inventory all instances of Java, distinguish between Oracle Java and open-source alternatives like OpenJDK, and determine whether they fall within the scope of the new licensing model. This audit process should be thorough, as even unintentional use of Oracle Java can lead to compliance issues.

Oracle BYOL: A Cost-Effective Alternative

As part of Oracle’s broader licensing strategy, the company offers a Bring Your Own License (BYOL) model. Oracle BYOL allows organizations to use their existing Oracle licenses when deploying in supported cloud environments, including Oracle Cloud Infrastructure (OCI) and certain third-party cloud providers.

For companies already invested in Oracle technologies, Oracle BYOL presents an opportunity to reduce costs and maximize ROI. It allows you to repurpose your on-premise licenses for cloud-based Java deployments, eliminating the need for redundant subscriptions. This flexibility can significantly reduce licensing expenditures while providing access to enterprise-grade support and features.

Notably, Oracle BYOL applies not just to Java but also to Oracle Database, WebLogic, and other middleware products. In the context of the Oracle Java license change, BYOL becomes an essential strategy for cloud migrations and hybrid IT models.

How to Use Oracle BYOL with Java

To take advantage of Oracle BYOL for Java, organizations must first ensure they have eligible licenses. These licenses must be covered under active support and compliance terms. Once verified, you can apply them to eligible cloud environments, reducing or eliminating the cost of additional Java subscriptions in those environments.

Here are key steps to implement Oracle BYOL effectively:

Conduct a License Review: Work with Oracle or a trusted licensing partner to review your existing entitlements.

Identify BYOL Opportunities: Determine where Oracle Java is deployed and whether those environments support BYOL.

Update Policies and Procedures: Ensure your procurement and IT teams understand the BYOL process and update documentation accordingly.

Monitor Usage: Implement tools to track license usage and ensure ongoing compliance.

When done correctly, Oracle BYOL can serve as a powerful tool to mitigate the financial impact of the Oracle Java license change.

OpenJDK: A Viable Alternative

In light of the license change, many organizations are also exploring alternatives to Oracle Java, such as OpenJDK. OpenJDK is a free and open-source implementation of the Java Platform, and it serves as the base for Oracle Java. Several vendors, including Amazon (Corretto), Red Hat, and Azul, provide enterprise-grade builds of OpenJDK, offering free updates and support options.

Switching to OpenJDK can help avoid licensing fees altogether. However, organizations should evaluate compatibility, performance, and support needs before making the transition. In some cases, sticking with Oracle Java and using Oracle BYOL may offer better support and stability, particularly for mission-critical systems.

Final Thoughts

The Oracle Java license change has reshaped how businesses manage their Java deployments. With Oracle now enforcing stricter licensing terms and pricing models, organizations must take a proactive approach to compliance. At the same time, the Oracle BYOL model offers a valuable path for reducing costs, especially for businesses moving to the cloud.

By understanding these changes and leveraging available licensing strategies, organizations can maintain operational continuity while controlling IT expenses. Whether you choose to remain with Oracle Java or migrate to OpenJDK, having a clear strategy in place is the best way to navigate the evolving Java ecosystem

Understanding Java Licensing Costs: Is Java Free?

Java has been one of the most popular programming languages for decades, used in everything from enterprise applications to mobile development. However, recent changes in Oracle’s licensing policies have sparked widespread discussions about Java licensing costs. Many businesses and developers are now asking: Is Java free? The answer to this question depends on how Java is used and which version is being implemented. In this article, we will break down Java’s licensing costs, clarify the different versions available, and help businesses and developers understand what is free and what is not.

The Evolution of Java Licensing

For years, Java was freely available under the Sun Microsystems’ leadership and continued to be free after Oracle acquired Sun in 2010. However, in 2019, Oracle introduced a new subscription-based licensing model for its Java SE (Standard Edition), creating confusion and uncertainty in the developer community.

Previously, businesses could use Oracle’s Java without worrying about licensing fees. But under the new model, users who need commercial support and updates must pay a subscription fee. This shift has led many to explore alternative versions of Java that remain free.

Is Java Free? Understanding the Different Versions

To answer the question Is Java free?, it’s essential to distinguish between the different distributions available. Java exists in multiple forms, and each comes with different licensing implications.

1. Oracle JDK (Java Development Kit)

Oracle JDK was historically the go-to version for enterprise users, but since 2019, Oracle has changed its licensing terms. Now, commercial use of Oracle JDK requires a subscription. If businesses continue using Oracle JDK without a valid license, they risk violating Oracle’s terms and potentially facing legal or financial consequences.

2. OpenJDK (Open Java Development Kit)

OpenJDK is an open-source implementation of Java and remains free to use under the GNU General Public License (GPL) with Classpath Exception. Many companies have switched to OpenJDK to avoid paying Java licensing costs. However, OpenJDK does not offer long-term support (LTS) from Oracle, meaning users must rely on community support or choose distributions backed by other vendors.

3. Other Java Distributions

Several organizations provide their own distributions of OpenJDK with long-term support and additional features. These include:

Adoptium (Eclipse Temurin): A popular, free OpenJDK build with community support.

Amazon Corretto: Amazon’s free distribution of OpenJDK with long-term support.

Red Hat OpenJDK: A Red Hat-supported OpenJDK distribution, often used in enterprise environments.

Azul Zulu: A commercial Java distribution with both free and paid options.

IBM Semeru: IBM’s OpenJDK variant with enterprise support.

Choosing the right Java version depends on an organization’s specific needs, whether it requires enterprise support, security patches, or simply a free Java runtime for development.

Breaking Down Java Licensing Costs

Oracle’s Java licensing costs are based on a subscription model, and the pricing varies depending on the number of users and computing power. Below is a basic outline of the cost structure:

Per-User Pricing: Oracle charges a fee per named user, commonly applied in desktop environments.

Per-Processor Pricing: For server environments, Oracle licenses Java based on the number of processors in use.

Enterprise Pricing Plans: Large organizations may negotiate customized pricing with Oracle.

For small businesses and individual developers, these costs can quickly add up. This is why many have shifted to OpenJDK or other free distributions to avoid licensing fees.

How to Avoid Java Licensing Costs

Since Java licensing costs can be substantial, businesses and developers should consider the following strategies to minimize expenses:

Switch to OpenJDK or Alternative Distributions Many organizations have already moved away from Oracle JDK to OpenJDK-based distributions. OpenJDK is functionally equivalent to Oracle JDK but is free to use.

Use Oracle JDK Only for Development Oracle allows free use of Java SE for development, testing, and personal use. However, deploying Oracle JDK in a production environment without a license can lead to fees.

Monitor Java Usage Organizations should conduct an internal audit to understand their Java usage and determine whether they need a paid license or can transition to a free alternative.

Consider Vendor-Supported OpenJDK Versions If enterprise support is necessary, companies can choose vendor-backed OpenJDK versions like Amazon Corretto, Red Hat OpenJDK, or Azul Zulu.

The Future of Java Licensing

As Oracle continues to refine its licensing policies, businesses and developers must stay informed about changes to Java licensing costs. OpenJDK and other free distributions are becoming increasingly popular, ensuring Java remains accessible to all.

For those wondering, Is Java free?, the answer is yes—but with some caveats. Developers and businesses must carefully assess their needs and choose the right Java distribution to balance cost, support, and long-term sustainability.

Conclusion

Java remains a critical technology in modern software development, but its licensing costs have created new challenges for businesses. Understanding Java licensing costs and answering the question Is Java free? requires careful evaluation of the different distributions available. By exploring alternatives like OpenJDK and vendor-supported versions, organizations can continue using Java while avoiding unnecessary expenses. Whether you are a developer, IT manager, or business owner, staying informed about Java licensing will help you make the best decision for your needs.

Using Docker for Full Stack Development and Deployment

1. Introduction to Docker

What is Docker? Docker is an open-source platform that automates the deployment, scaling, and management of applications inside containers. A container packages your application and its dependencies, ensuring it runs consistently across different computing environments.

Containers vs Virtual Machines (VMs)

Containers are lightweight and use fewer resources than VMs because they share the host operating system’s kernel, while VMs simulate an entire operating system. Containers are more efficient and easier to deploy.

Docker containers provide faster startup times, less overhead, and portability across development, staging, and production environments.

Benefits of Docker in Full Stack Development

Portability: Docker ensures that your application runs the same way regardless of the environment (dev, test, or production).

Consistency: Developers can share Dockerfiles to create identical environments for different developers.

Scalability: Docker containers can be quickly replicated, allowing your application to scale horizontally without a lot of overhead.

Isolation: Docker containers provide isolated environments for each part of your application, ensuring that dependencies don’t conflict.

2. Setting Up Docker for Full Stack Applications

Installing Docker and Docker Compose

Docker can be installed on any system (Windows, macOS, Linux). Provide steps for installing Docker and Docker Compose (which simplifies multi-container management).

Commands:

docker --version to check the installed Docker version.

docker-compose --version to check the Docker Compose version.

Setting Up Project Structure

Organize your project into different directories (e.g., /frontend, /backend, /db).

Each service will have its own Dockerfile and configuration file for Docker Compose.

3. Creating Dockerfiles for Frontend and Backend

Dockerfile for the Frontend:

For a React/Angular app:

Dockerfile

FROM node:14 WORKDIR /app COPY package*.json ./ RUN npm install COPY . . EXPOSE 3000 CMD ["npm", "start"]

This Dockerfile installs Node.js dependencies, copies the application, exposes the appropriate port, and starts the server.

Dockerfile for the Backend:

For a Python Flask app

Dockerfile

FROM python:3.9 WORKDIR /app COPY requirements.txt . RUN pip install -r requirements.txt COPY . . EXPOSE 5000 CMD ["python", "app.py"]

For a Java Spring Boot app:

Dockerfile

FROM openjdk:11 WORKDIR /app COPY target/my-app.jar my-app.jar EXPOSE 8080 CMD ["java", "-jar", "my-app.jar"]

This Dockerfile installs the necessary dependencies, copies the code, exposes the necessary port, and runs the app.

4. Docker Compose for Multi-Container Applications

What is Docker Compose? Docker Compose is a tool for defining and running multi-container Docker applications. With a docker-compose.yml file, you can configure services, networks, and volumes.

docker-compose.yml Example:

yaml

version: "3" services: frontend: build: context: ./frontend ports: - "3000:3000" backend: build: context: ./backend ports: - "5000:5000" depends_on: - db db: image: postgres environment: POSTGRES_USER: user POSTGRES_PASSWORD: password POSTGRES_DB: mydb

This YAML file defines three services: frontend, backend, and a PostgreSQL database. It also sets up networking and environment variables.

5. Building and Running Docker Containers

Building Docker Images:

Use docker build -t <image_name> <path> to build images.

For example:

bash

docker build -t frontend ./frontend docker build -t backend ./backend

Running Containers:

You can run individual containers using docker run or use Docker Compose to start all services:

bash

docker-compose up

Use docker ps to list running containers, and docker logs <container_id> to check logs.

Stopping and Removing Containers:

Use docker stop <container_id> and docker rm <container_id> to stop and remove containers.

With Docker Compose: docker-compose down to stop and remove all services.

6. Dockerizing Databases

Running Databases in Docker:

You can easily run databases like PostgreSQL, MySQL, or MongoDB as Docker containers.

Example for PostgreSQL in docker-compose.yml:

yaml

db: image: postgres environment: POSTGRES_USER: user POSTGRES_PASSWORD: password POSTGRES_DB: mydb

Persistent Storage with Docker Volumes:

Use Docker volumes to persist database data even when containers are stopped or removed:

yaml

volumes: - db_data:/var/lib/postgresql/data

Define the volume at the bottom of the file:

yaml

volumes: db_data:

Connecting Backend to Databases:

Your backend services can access databases via Docker networking. In the backend service, refer to the database by its service name (e.g., db).

7. Continuous Integration and Deployment (CI/CD) with Docker

Setting Up a CI/CD Pipeline:

Use Docker in CI/CD pipelines to ensure consistency across environments.

Example: GitHub Actions or Jenkins pipeline using Docker to build and push images.

Example .github/workflows/docker.yml:

yaml

name: CI/CD Pipeline on: [push] jobs: build: runs-on: ubuntu-latest steps: - name: Checkout Code uses: actions/checkout@v2 - name: Build Docker Image run: docker build -t myapp . - name: Push Docker Image run: docker push myapp

Automating Deployment:

Once images are built and pushed to a Docker registry (e.g., Docker Hub, Amazon ECR), they can be pulled into your production or staging environment.

8. Scaling Applications with Docker

Docker Swarm for Orchestration:

Docker Swarm is a native clustering and orchestration tool for Docker. You can scale your services by specifying the number of replicas.

Example:

bash

docker service scale myapp=5

Kubernetes for Advanced Orchestration:

Kubernetes (K8s) is more complex but offers greater scalability and fault tolerance. It can manage Docker containers at scale.

Load Balancing and Service Discovery:

Use Docker Swarm or Kubernetes to automatically load balance traffic to different container replicas.

9. Best Practices

Optimizing Docker Images:

Use smaller base images (e.g., alpine images) to reduce image size.

Use multi-stage builds to avoid unnecessary dependencies in the final image.

Environment Variables and Secrets Management:

Store sensitive data like API keys or database credentials in Docker secrets or environment variables rather than hardcoding them.

Logging and Monitoring:

Use tools like Docker’s built-in logging drivers, or integrate with ELK stack (Elasticsearch, Logstash, Kibana) for advanced logging.

For monitoring, tools like Prometheus and Grafana can be used to track Docker container metrics.

10. Conclusion

Why Use Docker in Full Stack Development? Docker simplifies the management of complex full-stack applications by ensuring consistent environments across all stages of development. It also offers significant performance benefits and scalability options.

Recommendations:

Encourage users to integrate Docker with CI/CD pipelines for automated builds and deployment.

Mention the use of Docker for microservices architecture, enabling easy scaling and management of individual services.
