MacOS下安装JDK1.8

一 概述

MacOS系统安装JDK1.8u133,并配置JAVA_HOME和PATH

二 JDK1.8 下载和安装

下载地址(直接复制到迅雷即可下载):
http://download.oracle.com/otn-pub/java/jdk/8u131-b11/d54c1d3a095b4ff2b6607d096fa80163/jdk-8u131-macosx-x64.dmg

在下载完JDK8的安装文件之后,双击安装按照提示进行操作即可,相当的简单。

完成之后在终端输入命令查看版本信息来验证是否安装成功。

localhost:Home tony$ java -version
java version "1.8.0_131"
Java(TM) SE Runtime Environment (build 1.8.0_131-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)
localhost:Home tony$ javac -version
javac 1.8.0_131

三 配置系统环境变量

1 切换root用户

localhost:~ tony$ su root
Password:

2 修改系统配置文件：

sh-3.2# vim /etc/profile

3 新增如下配置

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home
export PATH=$PATH:$JAVA_HOME/bin

4 应用配置

sh-3.2# source /etc/profile

5 验证 JAVA_HOME和PATH

localhost:tony root# echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home
localhost:tony root# echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/go/bin:/Applications/Wireshark.app/Contents/MacOS:/usr/local/git/bin:/Library/Frameworks/Python.framework/Versions/3.6/bin:/Users/tony/Documents/WS/go/bin:/Users/tony/Documents/Apache/apache-maven-3.3.9//bin:/Users/tony/Documents/gradle-4.0//bin:/Users/tony/Documents/WS/go/bin:/Users/tony/Documents/Apache/apache-maven-3.3.9//bin:/Users/tony/Documents/gradle-4.0//bin:/Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home/bin
localhost:tony root#

到这里就大功告成了
