Centos 7.2 下安装 jdk 1.8

Centos 下安装 jdk

1. 下载，需要绕过ssl

# cd /usr/local/java

wget --no-check-certificate --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/8u131-b11/d54c1d3a095b4ff 2b6607d096fa80163/jdk-8u131-linux-x64.tar.gz

2. 解压

tar -zxf jdk-8u131-linux-x64.tar.gz

3. 配置环境变量

vi /etc/profile

# ci文件末尾 添加

# jdk 1.8 settings start 2017-6-22
JAVA_HOME=/usr/local/java/jdk1.8.0_131
JRE_HOME=$JAVA_HOME/jre
PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib/dt.jar

export JAVA_HOME JRE_HOME PATH CLASSPATH

#jdk 1.8 settings end 2017-6-22

4.重新挂在配置文件

source /etc/profile

5.查看 java version

# 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)
