Therefore, we are now running the Oracle Java SE 13 as default java runtime environment. Since, we have installed Oracle Java SE 13 after OpenJDK 8. We have installed OpenJDK Java 8 and Oracle Java SE 13 on the same Linux server.īoth of these Java versions are available on the CentOS 8 server, but only one is set as default java runtime environment. Installing Multiple Java Runtime Environments: We have successfully installed Oracle Java SE 13 on Linux server.

We have installed OpenJDK Java Runtime Environment (JRE).

Here, we are installing OpenJDK 8 on our Linux server, but you can also install OpenJDK 11 by following the same steps.Ĭonnect with as root user by using a ssh client and install OpenJDK java runtime environment. The installation steps are same for both versions. Obviously, they are the open source implementations of Oracle Java SE 8 and Oracle Java SE 11. Two versions of OpenJDK are available in CentOS 8 standard yum repositories. OpenJDK is the free and open source implementation of Java Platform, Standard Edition (SE) and it is distributed under GNU GPL v2 license.
