離線安裝Docker
1. 二進制安裝
1. 下載離線包
2. 解壓
tar -zxvf docekr-xxx.tgz
3. 復制壓縮后的文件到指定文件夾
cp docker/* /usr/bin
4. 注冊編輯docker服務
vim /etc/systemd/system/docker.service
5. 添加可執行權限
chmod +x /etc/systemd/system/docker.service
6. 一鍵三連
systemctl daemon-reload
systemctl start docker
systemctl enable docker.service # 設置開機自啟動
參考docker.service

# Having non-zero Limit*s causes performance problems due to accounting overhead
# in the kernel. We recommend using cgroups to do container-local accounting.
# Uncomment TasksMax if your systemd version supports it.
# Only systemd 226 and above support this version.
#TasksMax=infinity

# set delegate yes so that systemd does not reset the cgroups of docker containers

WantedBy=multi-user.target
2. docker 卸載
1. 停掉docker服務
systemctl stop docker
2. 查看yum安裝的docker文件包
yum list installed |grep docker
3. 刪除所有安裝的docker文件包
yum -y remove docker.x86_64
4. 查看rpm包是否還有
rpm -qa |grep docker
5. 刪除docker鏡像放置的位置
rm -rf /var/lib/docker
