# Docker安裝 (僅針對CentOS7，CentOS6安裝Docker相對比較複雜)
yum remove docker-latest-logrotate docker-logrotate docker-selinux dockdocker-engine
yum install -y yum-utils device-mapper-persistent-data lvm2
# 添加docker官方源
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
yum makecache fast
yum install docker-ce
# 國內部分用戶可能無法連接docker官網提供的源，這裏提供阿里雲的鏡像節點供測試使用
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
rpm --import http://mirrors.aliyun.com/docker-ce/linux/centos/gpg
yum makecache fast
yum -y install docker-ce
systemctl start docker
systemctl status docker
# 添加加速器
第一種
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://6fvlc3jr.mirror.aliyuncs.com"]
}
EOF
sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://obww7jh1.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
第二種
用systemctl enable docker啓用服務後，編輯/etc/systemd/system/multi-user.target.wants/docker.service文件，找到 ExecStart= 這一行，在這行最後添加加速器地址 –registry-mirror=<加速器地址>
ExecStart=/usr/bin/dockerd --registry-mirror=https://6fvlc3jr.mirror.aliyuncs.com
重新啓動docker
sudo systemctl daemon-reload
sudo systemctl restart docker
