1. 离线一键部署（推荐）

• 包含：
  1） docker v1.19
  2）docker-compose v1.24.0

• 适用环境
  centos 7
  Ubuntu 18 +

• 下载地址
  >>> CSDN 下载连接

• 安装方式
  执行部署包中的compose_install.sh脚本即可。

2. 阿里云yum源安装

2.1 卸载旧版

# yum remove docker \
docker-common \ 
docker-selinux \ 
docker-engine 

有得文档上选择卸载组件比较多：

# yum remove docker \
docker-client \
docker-client-latest \
docker-common \
docker-latest \
docker-latest-logrotate \ 
docker-logrotate \
docker-selinux \
docker-engine-selinux \
docker-engine 

2.2 安装依赖包

# yum install -y yum-utils device-mapper-persistent-data lvm2

2.3 yum源

2.3.1 添加yum源

# yum-config-manager \
--add-repo \
https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo 

2.3.2 更新yum源

说明：非必要

yum-config-manager --enable docker-ce-edge

2.4 安装

1）清除缓存

yum makecache fast

2）安装

# yum install docker-ce -y

2.5 启动和添加开机启动项

# systemctl daemon-reload
# systemctl restart docker
# systemctl enable docker

3. 官方源安装（择版本选择）

3.1 卸载老版本的Docker

说明：同上

3.2 官方yum源

说明：要启用哪个版本的源就将其下的enable值设置为1

# cat /etc/yum.repos.d/docker-ce.repo

3.4 安装指定版本

说明：以docker-ce-18.06.0.ce-3.el7为例

# yum -y install docker-ce-18.06.0.ce-3.el7

3.5 启动docker 设置开机启动

# systemctl daemon-reload
# systemctl restart docker
# systemctl enable docker

4. 其他离线安装方式

4.1 rpm安装

• 安装包
  附件“离线安装包”目录中

• 安装

# rpm -vih docker-ce-selinux-17.03.3.ce-1.el7.noarch.rpm 
# rpm -vih docker-ce-17.03.3.ce-1.el7.x86_64.rpm4.rpm 

• 启动并设置开机启动

# systemctl daemon-reload
# systemctl restart docker
# systemctl enable docker

4.2 yum 安装

准备好yum用的rpm包，拷贝到服务器，执行

yum localinstall *.rpm

4.3 二进制文件安装

• 官网下载
  https://download.docker.com/linux/static/stable/x86_64/

• 解压缩

tar xf docker-xxxxx.tgz

• 拷贝二进制文件

cp docker/* /usr/bin/

• docker注册为server

创建 /etc/systemd/system/docker.service文件内容如下：

[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
 
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

• 给执行权限

chmod +x /etc/systemd/system/docker.service
systemctl daemon-reload

• 启动并设置开机启动

# systemctl daemon-reload
# systemctl restart docker
# systemctl enable docker

5. 普通用户使用docker

• 创建docker用户组

groupadd docker

• 将 liubei 用户加入docker组

gpasswd -a liubei docker

• 更新组信息

newgrp docker

• 重启docker

systemctl restart docker
