中标麒麟离线安装Docker

参照官方Install static binaries的过程

安装Docker

1. 在https://download.docker.com/linux/static/stable/下载对应版本的docker程序文件
2. 解压文件: tar xzvf /path/to/<FILE>.tar.gz
3. 把解压出来的文件移动到/usr/bin: sudo cp docker/* /usr/bin/
4. 把docker注册为服务，创建文件/usr/lib/systemd/system/docker.service，内容如下

[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target firewalld.service
Wants=network-online.target
  
[Service]
Type=notify
# the default is not to use systemd for cgroups because the delegate issues still
# exists and systemd currently does not support the cgroup feature set required
# for containers run by docker
ExecStart=/usr/bin/dockerd --selinux-enabled=false --insecure-registry=127.0.0.1
ExecReload=/bin/kill -s HUP $MAINPID
# Having non-zero Limit*s causes performance problems due to accounting overhead
# in the kernel. We recommend using cgroups to do container-local accounting.
LimitNOFILE=infinity
LimitNPROC=infinity
LimitCORE=infinity
# Uncomment TasksMax if your systemd version supports it.
# Only systemd 226 and above support this version.
#TasksMax=infinity
TimeoutStartSec=0
# set delegate yes so that systemd does not reset the cgroups of docker containers
Delegate=yes
# kill only the docker process, not all processes in the cgroup
KillMode=process
# restart the docker process if it exits prematurely
Restart=on-failure
StartLimitBurst=3
StartLimitInterval=60s
  
[Install]
WantedBy=multi-user.target

5. 设置镜像源，创建配置文件: /etc/docker/daemon.json，
   此处使用163的源，可以换其他源

{
  "registry-mirrors": ["http://hub-mirror.c.163.com"]
}

6. 按顺序执行以下命令：

命令	说明
chmod +x /usr/lib/systemd/system/docker.service	对docker.service授予执行权限
systemctl daemon-reload	重载服务配置
systemctl start docker	运行docker
systemctl status docker	运行docker
systemctl enable docker	使docker自动启动

使用其他用户执行docker命令

sudo groupadd docker          #添加docker用户组
sudo gpasswd -a $USER docker  #将登陆用户加入到docker用户组中
newgrp docker                 #更新用户组
