Rename jdk1.8.0_131 to jdk1.8 in order to make it easier to use mv

Move jdk1.8 to the / usr/local directory (of course, you can also move it to another directory, and then change the configuration environment variable to your own jdk path)

Tar-zxvf jdk-8u131-linux-x64.tar.gzmv jdk1.8.0_131 jdk1.8mv jdk1.8 / usr/local III. Configure environment variables

1. Modify / etc/profile file

Configure the jdk environment at the end of the profile file:

Export JAVA_HOME=/usr/local/jdk1.8export JRE_HOME=$ {JAVA_HOME} / jreexport CLASSPATH=.:$ {JAVA_HOME} / lib:$ {JRE_HOME} / lib:$CLASSPATHexport JAVA_PATH=$ {JAVA_HOME} / bin:$ {JRE_HOME} / binexport PATH=$PATH:$ {JAVA_PATH}

2. Make profile effective
