Centos安装JDK

 

[root@localhost ~]# java -version
java version "1.6.0"
OpenJDK  Runtime Environment (build 1.6.0-b09)
OpenJDK 64-Bit Server VM (build 1.6.0-b09, mixed mode)

1.6的，这个必须换掉 。下载jdk-7u3-linux-x64.rpm

# wget http://download.oracle.com/otn-pub/java/jdk/7u3-b04/jdk-7u3-linux-x64.rpm

 速度不咋的，可以用迅雷之类的下了传上去。

运行安装

# rpm -ivh jdk-7u3-linux-x64.rpm

 # vim /etc/profile

修改profile 最后面加入

export JAVA_HOME=/usr/java/jdk1.7.0_03
export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PATH:$JAVA_HOME/bin
