1. 下载地址

官网下载地址:下载
官网文档地址:文档

2. 解压并注册为service

1. 下载安装

# 下载
tarball="docker-18.09.7.tgz"
wget -c https://download.docker.com/linux/static/stable/x86_64/${tarball}
# 解压
tar -zxvf ${tarball}
# 复制到/usr/bin
cp docker/* /usr/bin

2. 添加到service: vim /etc/systemd/system/docker.service

这里是基础配置，详细配置可以使用指定配置文件来启动服务

[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 
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

3. 启动服务

#添加文件权限并启动docker
chmod +x /etc/systemd/system/docker.service
#重载unit配置文件
systemctl daemon-reload
#启动docker
systemctl start docker       
#设置开机自启
systemctl enable docker.service

4. 检查状态

# 状态
systemctl status docker
# 版本
docker -v
