Dokku로 Private PaaS 구축하기

서버에 Dokku를 깔았다. 전부터 Private PaaS를 구축하고 싶었기에 봐뒀던것이 DEIS인데 이녀석은 CoreOS라는 녀석이 Host에 깔려 있어야 한다. 내 서버는 우분투 14.04. MacMiniVault 에서는 다른 OS설치 옵션으로 Core OS는 지원하지 않는다. 그래서 고민하던 차에 알게된게 Dokku.

이녀석은 스케일 업,스케일 아웃 등은 지원하지 않는다.어짜피 서버 한대에서만 돌아가니까.

Dokku 프로젝트 주소

https://github.com/progrium/dokku

문서

http://progrium.viewdocs.io/dokku/index

설치환경은 깡통 우분트 14.04에서 도커만 깔려있는 상태였다.

설치는 명령줄 한줄로 가능하다. 혹시나 한번에 되지 않으면 다시 한번 실행시켜 주면 된다.

wget -qO- https://raw.github.com/progrium/dokku/v0.3.15/bootstrap.sh | sudo DOKKU_TAG=v0.3.15 bash

나는 아래처럼 종료되서 "apt-get install -qq -y python-software-properties" 를 한번 실행시켜 주고 다시 설치 스크립트를 실행했더니 설치 되었다.

이제 문제가 개발컴(노트북) 에서 서버로 git push 를 날리면 도쿠가 인식하도록 해줘야 하는 작업이 있는데 이게 되려면 개발컴에서 서버로 ssh로 접속할때 쓰는 서버 계정이 sudo명령어를 실행했을시 패스워드를 묻지 않아야 한다. ssh 로 root 연결이 가능하면 그렇게 해도 되긴하지만 보통 연결하는 서버 계정에 SU 패스워드를 물어보지 않도록 작업하는게 깔끔할듯.

서버에 /etc/sudoers 파일을 열어서 아래 한줄을 추가해준다.

사용자명 ALL=NOPASSWD: ALL

그리고 개발컴에서 다음을 실행해준다. 물론 개발컴 계정에서 공개키가 있어야 한다. 완료되면 다음줄처럼 :으로 구분되는 문자열이 출력된다.

$ cat ~/.ssh/id_rsa.pub | ssh 서버주소 "sudo sshcommand acl-add dokku 계정이름" 45:49:d1:f4:xx:xx:xx:xx:xx:xx:xx:xx:c5:4d:3a:61

이제 설치가 끝났다. heroku용 node.js 샘플을 올려서 테스트 해보자.

osx 에서 ruby 업그레이드

osx에서 ruby를 제대로 쓰려면 업그레이드를 해야한다. 요세미티도 마찬가지이다.

현재 요세미티 기본 설치후 루비버전은 2.0 이다. 업그레이드 하면 2.1.3 이된다.

업그레이드 자체는 무척 쉽다. sudo su - 로 root로 변환후 아래 명령어를 입력하면 된다.

devbox:~ root# \curl -sSL https://get.rvm.io | bash -s stable --ruby

그리고 ram use 로 버전을 지정해준다.

devbox:~ root# rvm use ruby-2.1.3

swift regular expression

swift로 정규식 사용하기. 근데 좀더 간단한 방법이 있음 좋겠다.

import Foundation // definition substring extension String { subscript (r: Range) -> String { get { let subStart = advance(self.startIndex, r.startIndex, self.endIndex) let subEnd = advance(subStart, r.endIndex - r.startIndex, self.endIndex) return self.substringWithRange(Range(start: subStart, end: subEnd)) } } func substring(from: Int) -> String { let end = countElements(self) return self[from..end] } func substring(from: Int, length: Int) -> String { let end = from + length return self[from..end] } func substring(range: Range ) -> String { let end = range.endIndex return self[range.startIndex..end] } } // regexp test println("swift regexp test") var sampleString = "ABCDEFG" var regexp = NSRegularExpression(pattern: "AB(.+)FG", options: nil, error: nil) var match = regexp.firstMatchInString(sampleString,options:nil,range:NSMakeRange(0,countElements(sampleString))) println( "sample string is " + sampleString) println( "count of math : \( match.numberOfRanges )" ) println(match.rangeAtIndex(0)) println(match.rangeAtIndex(1)) println(sampleString.substring(match.rangeAtIndex(0))) println(sampleString.substring(match.rangeAtIndex(1)))

인텔리j에서 spring + mybatis 조합에서 mapper.xml 찾지못해 오류일때

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlSessionFactory' defined in ServletContext resource [/WEB-INF/spring-config.xml]: Invocation of init method failed; nested exception is org.springframework.core.NestedIOException: Failed to parse mapping resource: 'class path resource [com/domain/sql/mapper/UserDao.xml]'; nested exception is java.io.FileNotFoundException: class path resource [com/domain/sql/mapper/UserDao.xml] cannot be opened because it does not exist

이런 에러가날때가 있다.

mybatis 설정 xml파일을 보면

<property name="mapperLocations" value="classpath:com/domain/sql/mapper/*.xml" />

이런식으로 되어있을텐데

<property name="mapperLocations" value="classpath*:com/domain/sql/mapper/*.xml" />

으로 바꿔주면 된다.

classpath뒤에 * 붙여주면 해결.
