This article introduces you how to install jdk8/java8 on CentOS8, the content is very detailed, interested friends can refer to, hope to be helpful to you.

Preface

At first, I wanted to download it with wget on CentOS8, then extract it and configure the environment variables, but I didn't do it well for a long time, so I gave up and installed it directly using yum.

1. Installation method

Yum is installed directly on CentOS8, and the environment variables are automatically configured.

2. Check to see if it is installed

The following results indicate that jdk has been installed and configured

[root@localhost] # java-versionopenjdk version "1.8.0,222" OpenJDK Runtime Environment (build 1.8.0_222-b10) OpenJDK 64-Bit Server VM (build 25.222-b10, mixed mode)

3. Uninstall

Check whether the system comes with jdk

Rpm-qa | grep javarpm-qa | grep jdkrpm-qa | grep gcj

If there is output information, the batch unloading system comes with

Rpm-qa | grep java | xargs rpm-e-nodeps

If you use the jdk installed by yum, uninstall it using the following command

Yum-y remove java-1.8.0-openjdk-headless.x86_64

4. Installation

4.1Check if there is a java1.8 package in yum

Yum list java-1.8*

4.2 start installation

Yum install java-1.8.0-openjdk*-y

5. Verification

[root@localhost] # java-versionopenjdk version "1.8.0,222" OpenJDK Runtime Environment (build 1.8.0_222-b10) OpenJDK 64-Bit Server VM (build 25.222-b10, mixed mode)
