[Unit]
 
Description=Docker Application Container Engine

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]

按Esc键后输入 :wq 保存并退出文件。
若不放心，可使用命令 cat docker.service 查看文件内容。

chmod +x docker.service

7 加载docker.service文件

systemctl daemon-reload

systemctl enable docker

10 验证是否安装成功

有 client 和 service 两部分表示安装成功了

docker version

11 查看docker状态

systemctl status docker

如下图即启动成功

12 设置日志

vi /etc/docker/daemon.json

复制以下内容到文件：

{ 
 "log-driver": "json-file",
  "log-opts": {
    "max-size": "100m",
    "max-file":"3"
  },
  "registry-mirrors": [
          "https://tng4fttt.mirror.aliyuncs.com",
          "https://registry.docker-cn.com",
          "http://hub-mirror.c.163.com",
