安裝docker

yum install -y yum-utils device-mapper-persistent-data lvm2

添加docker的yum源

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

配置鏡像加速器：自由選擇

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://zggyaen3.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

更新yum源緩存， 安裝docker-ce

$ sudo yum makecache fast
$ sudo yum install docker-ce

普通用戶需要加入docker組

$ sudo usermod -a -G docker ${USER}

修改docker存儲(chǔ)位置(可以不改)

$ sudo systemctl stop docker
$ sudo mv /var/lib/docker /home/lan/docker
$ sudo ln -s /home/lan/docker /var/lib/docker
$ sudo systemctl start docker
$ sudo systemctl enable docker

安裝docker-compose

$ sudo curl -L https://github.com/docker/compose/releases/download/1.25.5/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
$ sudo chmod +x /usr/local/bin/docker-compose
