CentOS 使用yum命令安装Java SDK(openjdk)

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 J***A(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：



centos-openjdk

在CentOS linux安装 J***A SDK

在命令行终端以root用户 输入以下命令yum安装 OpenSDK ：

[root@dabu.info ~]#yum install java-1.7.0-openjdk java-1.7.0-openjdk-devel #安装openjdk

输出如下：

Loaded plugins: downloadonly, fastestmirror, security

在centos linux上设置J***A_HOME environment variable(J***A_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J***A_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 J***A_HOME 指向 jre-1.7.0-openjdk.x86_64 这个链接。

即使用export命令:

[root@dabu.info ~]# export J***A_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 J***A_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 J***A_HOME=/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.51.x86_64

export CLASSPATH=.:$J***A_HOME/jre/lib/rt.jar:$J***A_HOME/lib/dt.jar:$J***A_HOME/lib/tools.jar

export PATH=$PATH:$J***A_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 $J***A_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



参考自《CentOS Install Java SDK using yum Command》,其中关于变量的文章和内容，我修改了下，因为它说的是sun
jdk 而不是 openjdk。
