 如果通过其他方法安装，可以参考 [配置文件模板](https://github.com/api7/apisix-build-tools/blob/master/usr/lib/systemd/system/apisix.service) 进行修改，并将其放置在 `/usr/lib/systemd/system/apisix.service` 路径下。

Review Comment:
   `yum search apisix` not really pretty good, it just to find `apisix` or not.
   
   `yum info apisix` maybe better, it can show the updated version.
   
   ```shell
   [root@lvs ~]# yum info apisix
