CentOS 6.X 和 5.X 自带有OpenJDK runtime environment  (openjdk)。它是一个在linux上实现开源的java 平台。CentOS  yum 命令 安装 Java SDK openjdk

centos linux JAVA(openjdk)软件包名
1.java-1.7.0-openjdk - OpenJDK Runtime Environment
2.java-1.7.0-openjdk-devel - OpenJDK Development Environment

输入以下命令,以查看可用的JDK软件包列表;
[root@dabu.info ~]# yum search java | grep -i --color JDK

输出类似下图:

在centos linux上设置JAVA_HOME environment variable(JAVA_HOME环境变量)

rhel 和 centos linux 使用yum命令后,将 OpenSDK 安装到/usr/lib/jvm/ 目录:
[root@dabu.info ~]# ls -l /usr/lib/jvm/

输出如下:
total 4
drwxr-xr-x. 3 root root 4096 Feb 24 17:00 java-1.7.0-openjdk-1.7.0.51.x86_64
lrwxrwxrwx. 1 root root   21 Feb 24 17:00 jre -> /etc/alternatives/jre
lrwxrwxrwx. 1 root root   27 Feb 24 17:00 jre-1.7.0 -> /etc/alternatives/jre_1.7.0
lrwxrwxrwx. 1 root root   38 Feb 24 17:00 jre-1.7.0-openjdk.x86_64 -> java-1.7.0-openjdk-1.7.0.51.x86_64/jre
lrwxrwxrwx. 1 root root   29 Feb 24 17:00 jre-openjdk -> /etc/alternatives/jre_openjdk

解释:输出的第二行的drwxr-xr-x.中的d表示是文件夹。其余的 l 表示链接。

设置JAVA_HOME指向一个含有java可执行程序的目录(一般是在 bin/java中)。我们用cd 命令进入到jvm下唯一的一个目录中 java-1.7.0-openjdk-1.7.0.51.x86_64 ,而 jre-1.7.0-openjdk.x86_64 这个链接是指向  java-1.7.0-openjdk-1.7.0.51.x86_64 这个文件夹,所以,可以直接用export命令将 JAVA_HOME 指向 jre-1.7.0-openjdk.x86_64 这个链接。
即使用export命令:
[root@dabu.info ~]#  export JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.51.x86_64
但是这样只能在当前会话中有效,一旦注销下线,就失效了。
所以最好保存到$HOME/.bashrc文件中(这个文件是针对指定用户的,如你是叫dabu用户,那么使用dabu用户登陆,然后输入命令:echo $HOME/.bashrc,就会显示你要修改的文件路径)
找到该文件后,在文件底部添加一行,如下:
export JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.51.x86_64
修改后保存关闭文件。

或者让系统上的所有用户使用java(openjdk) ,则要进行下面的操作:
[root@dabu.info ~]#  vi  /etc/profile
将下面的三行粘贴到 /etc/profile   中:
export JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.51.x86_64
export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PATH:$JAVA_HOME/bin

保存关闭,后,执行:
[root@dabu.info ~]#  source  /etc/profile
让设置立即生效。

在输入以下命令,来确认这三个变量是否设成了我们想要的:
[root@dabu.info ~]# echo $JAVA_HOME
[root@dabu.info ~]# echo $CLASSPATH
[root@dabu.info ~]# echo $PATH

测试java是否安装配置成功

查看 java 版本,输入命令:
[root@dabu.info ~]#  java     -version

创建一个java小程序测试下,名字叫 HelloWorld.java ,输入以下命令:
[root@dabu.info ~]# touch HelloWorld.java

将以下代码复制到 HelloWorld.java 中 :
public class HelloWorld {
pu
blic static void main(String[] args) {
System.out.println("Hello, World! This is a test code by nixCraft!");
}
}

复制进去后,保存关闭文件。编译和运行这个小程序,输入以下命令:
[root@dabu.info ~]#  javac HelloWorld.java
[root@dabu.info ~]#  java HelloWorld

会得到以下显示:
Hello, World! This is a test code by nixCraft!

如何(怎样)运行 .jar  这类java应用?

语法如下:
[root@dabu.info ~]# java -jar file.jar
[root@dabu.info ~]# java -jar /path/to/my/java/app.jar  #/path/to/my/java/app.jar表示应用的路径
[root@dabu.info ~]# java -jar /path/to/my/java/app.jar arg1 arg2   # arg1表示参数1 ,arg2表示参数2
