centos 上安装docker

如果软件包源访问错误，而又不处理，用disablerepo跳过。阿里云的服务器用的centos.

sudo yum --disablerepo=freeswitch -y install yum-utils device-mapper-persistent-data lvm2

sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

sudo yum --disablerepo=freeswitch -y install docker-ce docker-ce-cli containerd.io

sudo systemctl start docker

sudo systemctl enable docker
