配置：至少需要 2G 内存
先禁用 selinux
编辑配置文件：vim /etc/selinux/config
把 SELINUX=enforcing 改为 SELINUX=disabled
重启服务器
官网下载中有介绍其版本标识：https://jenkins.io/download/
我们就选用：Long-term Support (LTS)
官网关于 Docker 部署也有专门文档：https://github.com/jenkinsci/docker/blob/master/README.md
先创建一个宿主机以后用来存放数据的目录：mkdir -p /data/jenkins/jenkins_home && chmod 777 -R /data/jenkins/jenkins_home
安装镜像（813MB，有点大）：docker pull jenkins/jenkins:lts
查看下载下来的镜像：docker images
首次运行镜像：docker run --name jenkins-master -p 8123:8080 -p 50000:50000 -v /etc/localtime:/etc/localtime -v /data/jenkins/jenkins_home:/var/jenkins_home -e JAVA_OPTS="-Duser.timezone=Asia/Shanghai" -d --restart always jenkins/jenkins:lts
这里的 8080 端口是 jenkins 运行程序的端口，必须要有映射的。50000 端口是非必须映射的，但是如果你要用 Jenkins 分布式构建这个就必须开放
如果报下面的错误：
touch: cannot touch '/var/jenkins_home/copy_reference_file.log': Permission denied
Can not write to /var/jenkins_home/copy_reference_file.log. Wrong volume permissions?
解决办法：chown -R 1000:1000 /data/jenkins/jenkins_home，具体原因：点击查看
问题的本质就是，jenkins 镜像中的系统用户是：jenkins，当你进入容器 bash 内，输入：whoami && id，你就可以看到他的 uid 是 1000，所以这里才 chown 1000
查看容器运行情况：docker ps
进入容器中 Jenkins shell 交互界面：docker exec -it bd290d5eb0d /bin/bash
首次使用 Jenkins / Jenkins 插件推荐
我这里就不截图了，有需要截图可以看这博文，差不多就是这样的：点击我o(∩_∩)o
首次进入 Jenkins 的 Web UI 界面是一个解锁页面 Unlock Jenkins，需要让你输入：Administrator password
这个密码放在：/var/jenkins_home/secrets/initialAdminPassword，你需要先：docker exec -it ci_jenkins_1 /bin/bash
然后：cat /data/jenkins/jenkins_home/secrets/initialAdminPassword
也有可能是这个目录：cat /var/jenkins_home/secrets/initialAdminPassword
然后再接下来就是插件的安装，我推荐直接用它推荐给我们的插件直接安装，稍后再安装自己需要定制的。
插件安装完会进入：Create First Admin User 页面，填写一个用户信息即可。
我的这里的代码仓库是：Gitlab

Docker 的 Jenkins 与 Docker 结合使用
运行镜像命令：docker run --name jenkins-master -p 8123:8080 -p 50000:50000 -v /etc/localtime:/etc/localtime -v /data/jenkins/jenkins_home:/var/jenkins_home -v /var/run/docker.sock:/var/run/docker.sock -e JAVA_OPTS="-Duser.timezone=Asia/Shanghai" -d --restart always jenkins/jenkins:lts
比上面多了一步：-v /var/run/docker.sock:/var/run/docker.sock
这样，在 jenkins 里面写 shell 脚本调用 docker 程序，就可以直接调用宿主机的 docker 了。
sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo
sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key
sudo yum install -y jenkins
/etc/init.d/jenkins
/etc/logrotate.d/jenkins
/etc/sysconfig/jenkins
/usr/lib/jenkins
/usr/lib/jenkins/jenkins.war
/usr/sbin/rcjenkins
/var/cache/jenkins
/var/lib/jenkins
/var/log/jenkins
/usr/lib/jenkins/：jenkins安装目录，war 包会放在这里。
/etc/sysconfig/jenkins：jenkins配置文件，“端口”，“JENKINS_HOME” 等都可以在这里配置。
/var/lib/jenkins/：默认的 JENKINS_HOME。
/var/log/jenkins/jenkins.log：jenkins 日志文件。
vim /etc/sysconfig/jenkins
56 行：JENKINS_PORT="8080"
控制台输出方式启动：java -jar /usr/lib/jenkins/jenkins.war
内置 Jetty
可以看到有一个这个重点内容，这是你的初始化密码，等下会用到的：
