# 一、CentOS 7 #

1、下载docker安装包：[Index of linux/static/stable/x86\_64/][Index of linux_static_stable_x86_64]

2、将安装包随便放到系统某个目录下解压：tar -xvf docker-20.10.8.tgz

3、将解压后的docker目录中的所有内容拷贝到/usr/bin/目录下，放到此目录下相当于配置了环境变量即可以使用docker命令。（注：此处拷贝的内容不是整个docker目录而是docker目录下的所有文件）

4、将docker注册为service：vim /etc/systemd/system/docker.service

[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 --selinux-enabled=false --insecure-registry=127.0.0.1
    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

5、保存后给docker.service文件添加权限：chmod +x /etc/systemd/system/docker.service

6、重新加载配置文件（修改docker.service文件时都要重新加载下）：systemctl daemon-reload

7、启动docker：systemctl start docker

8、设置开机启动：systemctl enable docker.service

9、查看docker状态：systemctl status docker

10、查看docker版本：docker -v
