CentOS에서 Mysql,MariaDB,JDK 설치방법들

맨 아래에 JDK를 설치하는것중 openJDK와 openJDK-devel 이 있다.

개발적으로 조금 더 추가된 JDK인듯하다

stackoverflow에서 찾아본결과 아래와 같이 설명했다.

• java-1.7.0-openjdk.x86_64 is the package containing the JRE
• java-1.7.0-openjdk-devel contains the development stuff (basically things you should not need, if you only want to run Java applications).
