Instalar Java en Debian 10

Instalar Java en Debian 10. Java es es uno de los lenguajes de programación más populares, se utiliza para crear aplicaciones de escritorio, webs, para móviles, etc... Java viene con dos paquetes diferentes, uno es Java Runtime Environment (JRE), y el otro Java Development Kit (JDK). La diferencia entre ellos es sustancial, pero fácil de entender. Para ejecutar una aplicación basada en Java, solo necesitamos Java Runtime Environment, por otro lado, si queremos desarrollar una aplicación Java, es necesario el Kit de desarrollo de Java (JDK). Te aclaro que JDK incluye tanto JRE, como las bibliotecas de desarrollo y herramientas de depuración necesarias. En linux podemos elegir, tenemos OpenJDK y Oracle Java, ambos tienen las mismas funcionalidades y capacidades, pero Oracle Java tiene características comerciales. De forma predeterminada en linux se instala OpenJDK. Si no sabes cual elegir, de momento te quedas con OpenJDK, siempre estas a tiempo de cambiar. En este articulo vemos como instalar OpenJDK (versión 8 y 11), también Oracle Java. Tu decides.  

Instalar Java en Debian 10

Instalar OpenJDK Instalar OpenJDK 8 OpenJDK 8 está disponible en Debian 10 como el JDK predeterminado, así que tan solo debes ejecutar lo siguiente: sudo apt update sudo apt install default-jdk Verifica la versión instalada. java -version ejemplo de salida... sololinux # java -version openjdk version "1.8.0_222" OpenJDK Runtime Environment (build 1.8.0_222-8u222-b10-1-deb9u1~b10) OpenJDK 64-Bit Server VM (build 25.222-b10, mixed mode) Instalar OpenJDK 11 La ultima versión de OpenJDK es la 11, si la quieres instalar (en vez de la 8) debes agregar el repositorio Backports de Debian. echo 'deb http://ftp.debian.org/debian stretch-backports main' | sudo tee /etc/apt/sources.list.d/stretch-backports.list Instalamos... sudo apt update sudo apt install openjdk-11-jdk Ya tenemos OpenJDK instalado en nuestro Debian 10.   Instalar Oracle Java Antes de comenzar, debes tener en cuenta la Licencia Oracle Java; es gratis solo para uso no comercial, así que ten cuidado. Instalamos las dependencias requeridas. sudo apt install dirmngr gnupg Importamos la key, y habilitamos un nuevo repositorio. sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 73C3DB2A echo 'deb http://ppa.launchpad.net/linuxuprising/java/ubuntu bionic main' | sudo tee /etc/apt/sources.list.d/linuxuprising-java.list Continuamos con la instalación... sudo apt update sudo apt install oracle-java11-installer listo!!!!!!, ya lo tenemos.   Otras cosas... Las diferentes versiones de java pueden cohabitar entre ellas, no debe existir ningún problema. Si tienes varias versiones instaladas, incluso las tres que mencionamos en este articulo, puedes especificar cual es la que quieres que se ejecute de manera predeterminada. Lanza el siguiente comando, y selecciona la que más te interese. sudo update-alternatives --config java Si quieres desinstalar OpenJDK, es tan sencillo como: sudo apt remove default-jdk   Espero que este articulo te sea de utilidad, puedes ayudarnos a mantener el servidor con una donación (paypal), o también colaborar con el simple gesto de compartir nuestros artículos en tu sitio web, blog, foro o redes sociales.   Read the full article

Menginstall Flutter Tanpa Android Studio Di Windows 8.1

Pastikan internet konek lancar ya bro & sis, sediakan kopi dan cemilan wkwkwkkwk....mari kita mulai, di Windows 8.1, buka drive C: di Windows Explorer, lalu buat folder dengan nama “Android” di drive C: tersebut sehingga alamat foldernya menjadi C:Android . Folder ini akan kita pakai sebagai folder utama kita sepanjang artikel ini. Menginstall OpenJDK8 Selanjutnya download OpenJDK dari link https://github.com/AdoptOpenJDK/openjdk8-binaries/releases/download/jdk8u222-b10/OpenJDK8U-jdk_x64_windows_hotspot_8u222b10.zip . Ukuran file-nya sekitar 99MB. File ini adalah yang terbaru ketika artikel ini ditulis. Untuk file yang lebih baru, bisa dicek di https://github.com/AdoptOpenJDK/openjdk8-binaries/releases . Jangan lupa, nama file-nya selalu diawali dengan “OpenJDK8U-jdk_x64_windows_hotspot” lalu bertipe file .zip. Kalau sudah selesai didownload, ekstrak file tersebut lalu buka folder hasil ekstrakannya. di dalamnya ada folder dengan nama semacam “jdk8u222-b10”. Ubah nama folder tersebut menjadi “openjdk” lalu pindahkan folder tersebut ke dalam folder C:Android yang sudah kita buat sebelumnya sehingga alamatnya menjadi C:Androidopenjdk . Menginstall Flutter SDK Download Flutter SDK terbaru di https://flutter.dev/docs/development/tools/sdk/releases . ketika artikel ini ditulis, file SDK terbaru adalah https://storage.googleapis.com/flutter_infra/releases/stable/windows/flutter_windows_v1.7.8+hotfix.4-stable.zip .

Deploying Spring Boot Applications in the Google AppEngine Flex Environment

In this tutorial I will show how to set up a deployment of Spring Boot application for the AppEngine Flex environment in the Google cloud infrastructure.

Prerequisites

You should be familiar with the Spring Boot ecosystem and should be able to use Maven as a build tool.

Preparations for Google AppEngine Development

There are several general steps to go through in order to be able to deploy an application to the AppEngine environment.

Create a Google Cloud account and set up billing.

Create a new project. Accept the proposed project ID or choose your own. We will use the expression [PROJECT_ID] for the rest of this tutorial.

Download and install the GCP Cloud SDK.

Initialize the Cloud SDK so it points to your GCP project:

gcloud init [PROJECT_ID]

Spring Boot Demo Application

With the new AppEngine Flex Environment you are no longer restricted to the Jetty webframework in order to run web applications. So there is no need to tweak your Spring Boot dependencies in order to run in the GAE any more. (Check the differences between the standard and the flex environment.)

Our first Spring Boot application will feature a very simple REST controller:

@RestController public class HelloController { @RequestMapping("/hello") public String hello() { return "Hello AppEngine Flex"; } }

Since the AppEngine performs a health check by default, we are using the actuator starter and bind it to the required path in src/main/resources/application.yml:

management: context-path: /_ah security: enabled: false

For the sake of simplicity we are using the GAE legacy health check that will perform a GET request to /_ah/health.

AppEngine Flex Deployment

The AppEngine deployment descriptor has to be located in src/main/appengine/app.yaml. This are the most important settings:

service: sb-gcp # Id of the service env: flex # Flex environment runtime: java # Java runtime runtime_config: jdk: openjdk8 # use OpenJDK 8 ...

Your project holds several services. Each services needs a unique identifier that is set by the service parameter. Then we configure the flex environment and the Java runtime.

In order to deploy the Spring Boot application we are using this Maven plugin:

com.google.cloud.toolsappengine-maven-plugin1.3.2[PROJECT_ID]

Now we are ready for build an deployment:

mvn clean package appengine:deploy

The last Maven goal triggers the deployment which in the end is performed by the gcloud command line client from the Cloud SDK. This will run for some time. Basically, a Docker image containing your Spring Boot JAR is built and deployed to the GCP. After deploymemt is finally finished your application will show up in the

AppEngine Dashboard

Each deployment creates a new version of a service. Our AppEngine dashboard for the service named sb-gcp may look like this:

You can start and stop your service, go back to older versions etc.

And finally we see our running application at

https://sb-gcp-dot-[PROJECT_ID].appspot.com

That’s the output from our simple REST controller:

curl https://sb-gcp-dot-[PROJECT_ID].appspot.com/hello Hello AppEngine Flex

What’s next?

In upcoming posts I’ll show you how to access backends in the Google Compute Engine from Spring Boot applications.
