MacOS下安裝JDK1.8

一 概述

MacOS系統安裝JDK1.8u133,並配置JAVA_HOME和PATH

二 JDK1.8 下載和安裝

下載地址(直接複製到迅雷即可下載):
http://download.oracle.com/otn-pub/java/jdk/8u131-b11/d54c1d3a095b4ff2b6607d096fa80163/jdk-8u131-macosx-x64.dmg

在下載完JDK8的安裝文件之後,雙擊安裝按照提示進行操作即可,相當的簡單。

完成之後在終端輸入命令查看版本信息來驗證是否安裝成功。

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 配置系統環境變量

1 切換root用戶

localhost:~ tony$ su root
Password:

2 修改系統配置文件：

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 應用配置

sh-3.2# source /etc/profile

5 驗證 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#

到這裏就大功告成了
