linux 服务器上通过docker安装jenkins
1.搜索镜像 docker search jenkins 2.拉取镜像（注意此处拉取该镜像名称） docker pull jenkins/jenkins 3.宿主机创建目录，一会挂载到容器中 mkdir -p /2022data/container-conf/jenkins/jenkins-dev/jenkins_home 4.修改目录权限 chmod 777 /2022data/container-conf/jenkins/jenkins-dev/jenkins_home 5.创建jenkins容器 docker run -d -p 10241:8080 -p 10242:50000 -v /2022data/container-conf/jenkins/jenkins-dev/jenkins_home:/var/jenkins_home -v /etc/localtime:/etc/localtime --name jenkins-dev jenkins/jenkins 6.修改镜像地址，修改完后为下面内容。 vim /2022data/container-conf/jenkins/jenkins-dev/jenkins_home/hudson.model.UpdateCenter.xml 修改后内容为：7.获取登录密码 cat /2022data/container-conf/jenkins/jenkins-dev/jenkins_home/secrets/initialAdminPassword 8.登录访问 http://localhost:10421 用户：admin default https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json
