Ubuntu22安装Jenkins2.346.3

(1)安装OpenJDK
查看Java版本

java -version

sudo apt update
sudo apt install openjdk-11-jre

（2）安装Jenkins
更新安装源

curl -fsSL https://pkg.jenkins.io/debian-stable/jenkins.io.key | sudo tee /usr/share/keyrings/jenkins-keyring.asc > /dev/null

echo deb [signed-by=/usr/share/keyrings/jenkins-keyring.asc] https://pkg.jenkins.io/debian-stable binary/ | sudo tee /etc/apt/sources.list.d/jenkins.list > /dev/null

更新源

sudo apt-get update

安装Jenkins

sudo apt-get install jenkins

（3）设置开机自动启动Jenkins

sudo systemctl enable jenkins

（4）启动Jenkins

sudo systemctl start jenkins

（5）查看Jenkins运行状态

sudo systemctl status jenkins

systemctl cat jenkins

如果Jenkins运行出现问题或者无法启动，通过以下命令查看

journalctl -u jenkins.service 

Jenkins通过以下命令编辑环境配置，比如Jenkins的Web服务默认占用8080端口

systemctl edit jenkins 

[Service]
Environment="JENKINS_PORT=8081"

(7)配置Nginx反向代理
需要设置proxy_set_header的X-Forwarded-Host和X-Forwarded-Port，否则会出现代理配置错误的警告
自行百度Ubuntu22安装Nginx的方法。
Nginx的配置如下：

server {
    listen 80;
    server_name 127.0.0.1;

    #charset koi8-r;

    location / {
        proxy_pass http://127.0.0.1:8080;
        proxy_set_header X-Forwarded-Host 10.10.10.10; #Jenkins服务器所在域名或者服务器ip
        proxy_set_header X-Forwarded-Port 80;
        proxy_set_header Host $host;
    }
}

cat /var/lib/jenkins/secrets/initialAdminPassword
