Cloud server JAVA operating environment construction (3) - install JDK
Installing the JDK is relatively simple, simply run the following command:
yum search jdk yum -y install java-1.8.0-openjdk*
The prompt Complete indicates that the installation is complete. For the sake of insurance, you can use the java -version command to check whether the installation is really complete.
java -version
As shown in the figure below, a prompt similar to the following appears, indicating that the installation is successful
yum search jdk You can see that there are versions 1.6, 1.7, and 1.8. It is recommended to install jdk version 1.8, because if the jar package referenced in the project is compiled with jdk version 1.8, it may not be available.
