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
1
User=root
Group=root
2
Environment="JAVA_HOME=/usr/local/jdk-17.0.12+7/"
3
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
