参照官方Install static binaries的过程
安装Docker
- 在https://download.docker.com/linux/static/stable/下载对应版本的docker程序文件
- 解压文件:
tar xzvf /path/to/<FILE>.tar.gz - 把解压出来的文件移动到
/usr/bin:sudo cp docker/* /usr/bin/ - 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
- 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"]
}
- 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
