1. Upload JDK installation files to Linux
There are many kinds of methods, such as mount, share files, FTP, wget, etc., I use the SCP command
SCP jdk-8u131-linux-x64.rpm [Email protected]:/xiaol/software/
2. Login to Linux to enter the/xiaol/software/directory
Cd/xiaol/software/
3. Installing with tar
TAR-ZXVF jdk-8u131-linux-x64.tar.gz
4. Verify that the installation is successful
The jdk1.8.0_131 folder is created in/xiaol/software/after the previous step is completed
Execute the jdk1.8.0_131/bin/directory execution Java file:./java-version
5. Setting Environment variables
