1、安装java环境
sudo apt-get isntall openjdk-11-jdk
验证
qiang@09230:~$ java -version
openjdk version "11.0.15" 2022-04-19
OpenJDK Runtime Environment (build 11.0.15+10-Ubuntu-0ubuntu0.20.04.1)
OpenJDK 64-Bit Server VM (build 11.0.15+10-Ubuntu-0ubuntu0.20.04.1, mixed mode, sharing)

2、安装Jenkins
2.1Jenkins 的 Debian 软件包存储库，用于自动安装和升级。要使用此存储库，首先将密钥添加到您的系统
wget -q -O - https://pkg.jenkins.io/debian-stable/jenkins.io.key | sudo apt-key add -
2.2、添加一个 Jenkins apt 存储库条目
在/etc/apt/sources.list中添加deb https://pkg.jenkins.io/debian-stable binary/
sudo vim /etc/apt/sources.list

2.3、更新你的本地包索引
sudo apt-get update
如果发现如下错误，通过安装一个包解决
sudo apt install ca-certificates
Hit:73 http://ppa.launchpad.net/mosquitto-dev/mosquitto-ppa/ubuntu focal InRelease
Ign:72 https://pkg.jenkins.io/debian-stable binary/ InRelease

qiang@09230:~$
3、启动Jenkins
启动
sudo service jenkins start
或
sudo systemctl start jenkins
查看jenkins运行状态
如下显示active处于活跃状态
qiang@09230:~$ systemctl status jenkins
● jenkins.service - Jenkins Continuous Integration Server
Loaded: loaded (/lib/systemd/system/jenkins.service; enabled; vendor preset: enabled)
Active: active (running) since Wed 2022-05-18 17:53:44 CST; 1h 51min ago

qiang@09230:~$
设置jenkins跟随系统开机自启动
sudo systemctl enable jenkins
4、访问Jenkins
此时输入网址在服务器的8080端口下可以访问Jenkins
按如下图指引建立Jenkins账号并登录：
