docker -v#配置开机自启动
systemctl enable docker.service#6. 启动docker
systemctl start docker#7. 查看docker 启动状态
systemctl status docker

安装Rancher

 创建Rancher挂载目录

mkdir -p /data/rancher_home/rancher
mkdir -p /data/rancher_home/auditlog

部署Rancher

docker run -d --privileged --restart=unless-stopped -p 80:80 -p 443:443 \
-v /data/rancher_home/rancher:/var/lib/rancher \
-v /data/rancher_home/auditlog:/var/log/auditlog \
