Docker部署

echo "net.bridge.bridge-nf-call-iptables=1" >> /etc/sysctl.conf
sysctl -p

sudo yum -y install docker-ce
sudo systemctl enable docker --now

Rancher部署

这里使用Docker部署（生产环境不建议）

docker run -d --restart=unless-stopped \
  -p 8080:80 \
  -p 8443:443 \
  --name rancher \
  --privileged \
  -v /data/docker_data/rancher:/var/lib/rancher \
