Centos 下安装 jdk

1. 下载，需要绕过ssl

# cd /usr/local/javawget --no-check-certificate --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/8u131-b11/d54c1d3a095b4ff2b6607d096fa80163/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 2017-6-22JAVA_HOME=/usr/local/java/jdk1.8.0_131JRE_HOME=$JAVA_HOME/jrePATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/binCLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib/dt.jarexport JAVA_HOME JRE_HOME PATH CLASSPATH#jdk 1.8 settings end 2017-6-22

4.重新挂在配置文件
