1. Create a new Java folder under the / usr/local directory

Mkdir / usr/local/java

Copy the jdk to / usr/local/java, enter the java folder, and extract the package

Tar xvf jdk-8u181-linux-x64.tar.gz

2. Setting environment variables here uses the global setting method, that is, modify etc/profile, which is a common environment variable for all users to find / etc/profile, edit, and add at the end.

Export JAVA_HOME=/usr/local/java/jdk1.8.0_181export JRE_HOME=/usr/local/java/jdk1.8.0_181/jreexport CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib:$CLASSPATHexport PATH=$JAVA_HOME/bin:$PATH

In the above process of adding, do not add spaces on both sides of the equal sign, otherwise "is not a valid identifier" will appear, because the source / etc/profile cannot recognize extra spaces, which will be understood as part of the path.

And save it.

Run the following command to make profile effective.

Source / etc/profile

3. Verify whether the terminal is successful or not.
