systemd systemctl命令

前言

由于docker学习需要一些成本，我们这里直接使用Linux自带的service命令进行服务的部署。

---

编写service文件

为每个微服务创建一个 Systemd 服务文件，并位于 /etc/systemd/system/ 目录下。
Description: 对该服务的简短描述。
After: 指定该服务在 network.target 之后启动，表示网络服务已经可用。
ExecStart: 指定启动服务时执行的命令及其路径。
WorkingDirectory: 指定服务运行时的工作目录。
Restart: 设定重启策略，on-failure 表示当服务因错误退出时自动重启。
WantedBy=multi-user.target 意味着当系统进入多用户模式（即一般用户可以登录的状态）时，这个服务将被启动
