建议系统方式安装jenkins，除非你想踩踩docker版本的坑

系统直装

系统中已完成jenkins安装
如果在jenkins中需要使用docker，在宿主机上装完docker后，记得添加一下用户组:

gpasswd -a jenkins docker;newgrp docker

-下载证书文件

[ ! -d /var/lib/jenkins/update-center-rootCAs ] && mkdir /var/lib/jenkins/update-center-rootCAs
wget https://cdn.jsdelivr.net/gh/lework/jenkins-update-center/rootCA/update-center.crt -O /var/lib/jenkins/update-center-rootCAs/update-center.crt
chown jenkins.jenkins -R /var/lib/jenkins/update-center-rootCAs

修改源

sed -i 's#https://updates.jenkins.io/update-center.json#https://cdn.jsdelivr.net/gh/lework/jenkins-update-center/updates/tsinghua/update-center.json#' /var/lib/jenkins/hudson.model.UpdateCenter.xml
rm -f /var/lib/jenkins/updates/default.json 
systemctl restart jenkins

systemctl restart jenkins

查看密码

cat /var/lib/jenkins/secrets/initialAdminPassword

Docker

1、

docker run -itd 
--env JAVA_OPTS=-Dhudson.model.DownloadService.noSignatureCheck=true 
--name jekins 
-v jenkins_home:/var/jenkins_home 
-p 8080:8080 -p 50000:50000 
jenkins/jenkins:lts-jdk11

2、等待Web可以访问到jekins，再执行下面命令,替换为国内源，否则会报文件不存在
docker exec jekins sed -i 's#https://updates.jenkins.io/update-center.json#https://cdn.jsdelivr.net/gh/lework/jenkins-update-center/updates/tsinghua/update-center.json#' /var/jenkins_home/hudson.model.UpdateCenter.xml

3、重启
docker restart jekins

4、查看initialAdminPassword
docker logs -f jekins
