一、基础环境

1、操作系统：CentOS 7.3

2、Docker版本：18.06.1 官方下载地址

3、百度云Docker 18.06.1地址：链接：https://pan.baidu.com/s/1UJCeNWOhVOmtsnCCq48p1w 提取码：r5vn

复制这段内容后打开百度网盘手机App，操作更方便哦

二、Docker安装

1、解压

tar -xvf docker-18.06.1-ce.tgz

2、将解压出来的docker文件内容移动到 /usr/bin/ 目录下

cp docker/* /usr/bin/

3、将docker注册为service

vim /etc/systemd/system/docker.service

将下列配置加到docker.service中并保存

[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]

WantedBy=multi-user.target

4、启动

chmod +x /etc/systemd/system/docker.service #添加文件权限并启动docker

systemctl daemon-reload #重载unit配置文件

systemctl start docker #启动Docker

systemctl enable docker.service #设置开机自启

5、验证

systemctl status docker #查看Docker状态

docker -v #查看Docker版本
