-- 用yum源安装
## 安装docker(版本为1.13.1)
yum -y install docker
## 启动docker
systemctl start docker
## 查看docker状态
systemctl status docker
-- 离线安装docker
## 下载官方安装包wget https://download.docker.com/linux/static/stable/x86_64/docker-19.03.8-ce.tgz
## 解压tar -zxvf docker-19.03.8-ce.tgz
## 将解压出来的docker文件复制到 /usr/bin/ 目录下cp docker/* /usr/bin/
## 在/etc/systemd/system/目录下新增docker.service文件,内容如下,这样可以将docker注册为service服务### 在系统服务目录里创建nginx.service文件vi /etc/systemd/system/docker.service
### 写入内容如下:[Unit]

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.

# set delegate yes so that systemd does not reset the cgroups of docker containers

[Install]
WantedBy=multi-user.target
## 启动docker### 给docker.service文件添加执行权限chmod +x /etc/systemd/system/docker.service
### 重新加载配置文件(每次有修改docker.service文件时都要重新加载下)
systemctl daemon-reload
### 启动
systemctl start docker
## 设置开机启动
systemctl enable docker.service
## 查看docker服务状态
systemctl status docker
