1: First, create a directory in the Linux system to store JDK files. You can choose to create a new folder under the /opt directory, such as /opt/jdk.
sudo mkdir /opt/jdk
2: Copy the downloaded jdk-8u381-linux-x64.tar.gz file into the newly created directory.
sudo cp jdk-8u381-linux-x64.tar.gz /opt/jdk
3: Enter the directory and unzip the tar.gz file.
cd /opt/jdk
sudo tar -zxvf jdk-8u381-linux-x64.tar.gz
After the decompression is complete, a folder named jdk1.8.0_381 (the specific version number may vary) will be generated in the directory. Use the ls command to confirm that the folder has been decompressed correctly.
4: Next, open the terminal configuration file (such as .bashrc or .profile file). The default is to add the following content at the end of the file
in /etc/profile , and set the JAVA_HOME and PATH environment variables.
5: The configuration is basically completed. Now refresh the configuration file configuration and execute java -version to see that the jdk installation is complete.
