首先从sun下载jdk1.5*.bin

一、java安装

#./jdk*.bin

选择yes就ok了

二、java环境变量的设置

export JAVA_HOME=/usr/local/jdk1.5

export CLASSPATH=$JAVA_HOME/lib:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/mysql_connector.jar:$JAVA_HOME/jre/lib

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

export JRE_HOME=$JAVA_HOME/jre

三、测试

[root@localhost root]# vi HelloWorld.java

public class HelloWorld

{

public static void main(String[] args)

{

System.out.println("hello world in linux");

}

}

[root@localhost root]# javac HelloWorld.java

[root@localhost root]# java HelloWorld

hello world in linux

总结：测试成功！呵呵！
