在centos7上将通过yum安装的docker-ce-23.0.1 注册为系统服务

可以按照以下步骤在CentOS 7上将Docker CE 23.0.1注册为系统服务：

1. 首先，使用以下命令安装Docker CE 23.0.1：

   sudo yum install docker-ce-23.0.1

2. 然后，创建一个新的systemd服务文件来启动Docker CE。使用以下命令打开一个新文件：

   sudo nano /etc/systemd/system/docker.service

3. 将以下内容复制并粘贴到该文件中：

   [Unit]
   Description=Docker Application Container Engine
   Documentation=https://docs.docker.com
   After=network-online.target docker.socket firewalld.service
   Wants=network-online.target
   Requires=docker.socket

   [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
   TimeoutSec=0
   RestartSec=2
   Restart=always

   # Note that StartLimit* options were moved from "Service" to "Unit" in systemd 229.
   # Both the old, and new location are accepted by systemd 229 and later, so using the old location
   # to make them work for either version of systemd.
   StartLimitBurst=3

   # Note that StartLimitInterval was renamed to StartLimitIntervalSec in systemd 230.
   StartLimitInterval=60s

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

   [Install]
   WantedBy=multi-user.target

4. 保存和关闭该文件。

5. 开启新的systemd服务并使其自动启动：

   sudo systemctl daemon-reload
   sudo systemctl enable docker
   sudo systemctl start docker

6. 确认服务已成功启动：

   sudo systemctl status docker

如果服务已成功启动，则会显示Active（运行中）状态。
