OpenJDK17U-jdk_x64_linux_hotspot_17.0.12_7.tar.gz

$root@node33-104 tmp$ # tar xf OpenJDK17U-jdk_x64_linux_hotspot_17.0.12_7.tar.gz

$root@node33-104 tmp$ #mv jdk-17.0.12+7/ /usr/local/

source /etc/profile

2、openjdk 17 安装完成

$root@node33-104 tmp$ # java -version

openjdk version "17.0.12" 2024-07-16

OpenJDK Runtime Environment Temurin-17.0.12+7 (build 17.0.12+7)

OpenJDK 64-Bit Server VM Temurin-17.0.12+7 (build 17.0.12+7, mixed mode, sharing)

$root@node33-104 tmp$ #

3、jenkins 2.479.1 rpm安装完成

//获取文件后，安装

$root@node33-104 tmp$ # ls jenkins-2.479-1.1.noarch.rpm

jenkins-2.479-1.1.noarch.rpm

$root@node33-104 tmp$ # yum install -y /tmp/jenkins-2.479-1.1.noarch.rpm

4、jenkins配置

vi /usr/lib/systemd/system/jenkins.service

修改为一下

User=root

Group=root

Environment="JAVA_HOME=/usr/local/jdk-17.0.12+7/"

Environment="JENKINS_JAVA_CMD=/usr/local/jdk-17.0.12+7/bin/java"

4//8080访问端口是默认高危常见端口，可以自定义

Environment="JENKINS_PORT=8080"

5、启动jenkins，并开机自启

$root@node33-104 tmp$ # systemctl start jenkins

$root@node33-104 tmp$ # systemctl status jenkins

● jenkins.service - Jenkins Continuous Integration Server

Loaded: loaded (/usr/lib/systemd/system/jenkins.service; disabled; vendor preset: disabled)

Active: active (running) since Wed 2024-10-09 17:19:51 CST; 2 days ago

$root@node33-104 tmp$ # ss -atnl

LISTEN 0 50 $::$ :8080 $::$ 😗

$root@node33-104 tmp$ # systemctl enable jenkins

6、访问jenkins

ip+8080

亲测有效

既可以安装，需要的插件了，开始了
