wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat/jenkins.repo

rpm --import https://pkg.jenkins.io/redhat/jenkins.io.key

yum install jenkins

三、安装docker

yum install -y docker-io

service docker start

开启远程连接

vi /usr/lib/systemd/system/docker.service

ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock \

systemctl daemon-reload // 1，加载docker守护线程

systemctl restart docker // 2，重启docker

四、开机启动

vi /etc/rc.d/rc.local

service docker start

chmod +x /etc/rc.d/rc.local
