vi /etc/profile

export JAVA_HOME=/usr/local/jdk-17.0.12+7
export JRE_HOME=$JAV{A}_{H}OME/jreexportCLASSPATH=.:${JAVA_HOME}/lib:$JR{E}_{H}OME/libexportPATH=$JAVA_HOME/bin:$JR{E}_{H}OME/bin:$PATH

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
