CentOS configuration environment Variables for JDK

1, first of all, the JDK under the CentOS environment configuration in two cases, has been the root user-level JDK configuration, the other is the other user group-level configuration. The root user-level configuration is explained here.

We have downloaded the directory to unzip the JDK. As follows

2, edit the environment variable configuration file:

Vi/etc/profile

Add the following code at the tail:

#JDK全局环境变量配置
Export java_home=/usr/local/java/jdk1.8.0_181
Export Classpath=$:classpath: $JAVA _home/lib/
Export path= $PATH: $JAVA _home/bin

Also modify the storage location of the JDK on the export java_home= own Linux . The other two lines do not need to be modified

3. Let the environment variable configuration take effect. Use the following command:source/etc/profile

4, use Java and Javac command to query whether the configuration is in effect.

When this happens, the environment variables are basically well configured.

Java

Javac
