[[email protected] application]# ls -l /application/|grep jdk

lrwxrwxrwx  1 root root   12 9月   3 20:56 jdk -> jdk1.6.0_27/

drwxr-xr-x 10 root root 4096 9月   3 20:47 jdk1.6.0_27

6）检查JDK安装是否正确

[[email protected] application]# java -version

-bash: java: command not found

[[email protected] application]# /application/jdk/bin/java -version

java version "1.6.0_27"

Java(TM) SE Runtime Environment (build 1.6.0_27-b07)

Java HotSpot(TM) 64-Bit Server VM (build 20.2-b06, mixed mode)

7)设置环境变量

echo ‘#java env begin‘ >>/etc/profile

echo ‘export JAVA_HOME=/application/jdk‘ >>/etc/profile

echo ‘export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib‘ >>/etc/profile

echo ‘export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH:$HOME/bin‘ >>/etc/profile

echo ‘#java env end‘ >>/etc/profile

[[email protected] application]# tail -6 /etc/profile

alias vi=‘vim‘

#java env begin

export JAVA_HOME=/application/jdk

export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib

export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH:$HOME/bin

#java env end

8)检查环境变量

[[email protected] application]# echo $PATH

/application/jdk/bin:/application/jdk/jre/bin:/application/jdk/bin:/application/jdk/jre/bin:/application/jdk/bin:/application/jdk/jre/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/root/bin:/root/bin:/root/bin

[[email protected] application]# echo $JAVA_HOME

/application/jdk

[[email protected] application]# echo $CLASSPATH
