‘$/sbin/restart nginx’和‘$service nginx restart’之间有什么区别？

Question

我希望在增加nginx中的文件描述符限制后重新启动/etc/security/limits.d/nginx.conf，并且需要重新启动nginx进程以使更改生效。

我应该使用$/sbin/restart nginx还是$service nginx restart，区别是什么？

作为参考，/sbin/restart是什么：

$ /sbin/restart --help
Usage: restart [OPTION]... JOB [KEY=VALUE]...
Restart job.

Options:
  -n, --no-wait               do not wait for job to restart before exiting
      --system                use D-Bus system bus to connect to init daemon
      --dest=NAME             destination well-known name on system bus
  -q, --quiet                 reduce output to errors only
  -v, --verbose               increase output to include informational messages
      --help                  display this help and exit
      --version               output version information and exit

JOB is the name of the job that is to be restarted, this may be followed by zero or more environment variables to be defined in the job after
restarting.

The environment also serves to distinguish between job instances, and thus decide which of multiple instances will be restarted.

使用sbin/nginx，您可以直接向nginx发送命令。

服务也这样做(检查屏幕截图)：

在我的ubuntu服务器上，我没有/sbin/restart，如果您有它，请尝试执行cat /sbin/restart。
