[root@ci-node01 ~]# ls
anaconda-ks.cfg  apache-maven-3.6.3-bin.tar.gz  jdk-8u171-linux-x64.tar.gz
[root@ci-node01 ~]# tar xf jdk-8u171-linux-x64.tar.gz 
[root@ci-node01 ~]# mv jdk1.8.0_171/ /usr/local/jdk
[root@ci-node01 ~]# 
[root@ci-node01 ~]# tar xf apache-maven-3.6.3-bin.tar.gz 
[root@ci-node01 ~]# mv apache-maven-3.6.3 /usr/local/maven

2.部署Jenkins

[root@ci-node01 ~]# docker run -d \
--name jenkins \
--restart always \
-p 80:8080 \
-p 50000:50000 \
-u root \
-v /opt/jenkins_home:/var/jenkins_home \
-v /var/run/docker.sock:/var/run/docker.sock \
-v /usr/bin/docker:/usr/bin/docker \
-v /usr/local/maven:/usr/local/maven \
-v /usr/local/jdk:/usr/local/jdk \
-v /etc/localtime:/etc/localtime \

使用浏览器登录Jenkins：http://ip:port

3.修改Jenkins插件URL

在Jenkins找到Jenkins--->Manege Jenkins--->Manage Plugins--->Advanced--->Update Site
把URL改为https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json

sed -i 's#https://updates.jenkins.io/update-center.json#https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/unter.json#g' hudson.model.UpdateCenter.xml

[root@ci-node01 ~]# cd /opt/jenkins_home/updates/
[root@ci-node01 /opt/jenkins_home/updates]# ll -h
total 1.9M
-rw-r--r-- 1 root root 1.8M Apr  9 14:47 default.json
-rw-r--r-- 1 root root 5.3K Apr  9 14:47 hudson.tasks.Maven.MavenInstaller
[root@ci-node01 /opt/jenkins_home/updates]# sed -i 's#http://updates.jenkins-ci.org/download#https://mirrors.tuna.tsinghua.edu.cn/jenkins#g' default.json
[root@ci-node01 /opt/jenkins_home/updates]# sed -i 's#http://www.google.com#https://www.baidu.com#g' default.json

修改URL后重启容器，会发现安装插件非常快。
