Linux源码安装Java
1、到官网下载
jdk-8u131-linux-x64.tar.gz
官网地址:http://www.Oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
2、解压安装包,重命名为jdk
[root@QIANZI-BASE home]# tar -zvxf jdk-8u131-linux-x64.tar.gz
[root@QIANZI-BASE home]# mv jdk1.8.0_131 jdk
3、安装jdk到/usr/local/
[root@QIANZI-BASE home]# mv jdk /usr/local/
[root@QIANZI-BASE home]# cd /usr/local/
4、配置环境变量
[root@QIANZI-BASE local]# vim /etc/profile
在文件尾添加:
export JAVA_HOME=/usr/local/jdk
export JRE_HOME=/usr/local/jdk/jre
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH
5、使立即生效
source /etc/profile
6、验证
[root@QIANZI-BASE local]# java -version
java version "1.8.0_131"
Java(TM) SE Runtime Environment (build 1.8.0_131-b11)
