refer to : https://docs.redhat.com/en/documentation/red_hat_build_of_openjdk/17/html-single/installing_and_using_red_hat_build_of_openjdk_17_on_rhel/index#installing-jdk-on-rhel-using-archive_openjdk

1.Create a directory to where you want to download the archive file, and then navigate to that directory on your command-line interface (CLI).

cd /opt
mkdir OpenJdk

pwd
/opt/OpenJdk

2.download the JDK archive for Linux to your local system.
https://access.redhat.com/jbossnetwork/restricted/listSoftware.html?downloadType=distributions&product=core.service.openjdk&version=11.0.15

3.Extract the contents of the archive to a directory of your choice:

tar -xf java-17-openjdk-17.0.12.0.7-1.portable.jdk.el.x86_64.tar.xz 

mv java-17-openjdk-17.0.12.0.7-1.portable.jdk.el.x86_64 Jdk17

4.editor /etc/profile，Configure the JAVA_HOME environment variable:

vim /etc/profile

## 按大G健，切换最后一行，添加以下内容
export JAVA_HOME=/opt/OpenJdk/Jdk17
export PATH="$JAVA_HOME/bin:$PATH"

上面的第二行内容的目的是：
Add the bin directory of the generic JRE path to the PATH environment variable

5.生效

# 使配置文件生效
source /etc/profile

# verify
printenv | grep JAVA_HOME
java -version

6.如果装了多个版本的jdk，想指定使用某个版本jdk时，指定java路径就行了

[root@mqxctest Jdk17]# /opt/OpenJdk/Jdk17/bin/java --version
openjdk 17.0.12 2024-07-16 LTS
OpenJDK Runtime Environment (Red_Hat-17.0.12.0.7-1) (build 17.0.12+7-LTS)
