 ## Configuration File on Server Side
 
-On the server side, the actual service of TDengine is provided by an executable `taosd` whose parameters can be configured in file `taos.cfg` to meet the requirements of different use cases. The default location of `taos.cfg` is `/etc/taos`, but can be changed by using `-c` parameter on the CLI of `taosd`. For example, the configuration file can be put under `/home/user` and used like below

 ## 为服务端指定配置文件
 
-TDengine 系统后台服务由 taosd 提供，可以在配置文件 taos.cfg 里修改配置参数，以满足不同场景的需求。配置文件的缺省位置在/etc/taos 目录，可以通过 taosd 命令行执行参数 -c 指定配置文件目录。比如，指定配置文件位于`/home/user` 这个目录：
