apache - apachectl 和 apache2 之间的区别

Question

我尝试重新启动我的 Apache 服务器，我对此很陌生。我很想知道apache2重启是做什么的？apachectl restart 是做什么的？

Answer 1

假设您使用的是 Ubuntu 或类似系统，man apache2 会指示以下内容:

In general, apache2 should not be invoked directly, but rather should be invoked via /etc/init.d/apache2 or apache2ctl.

仅供引用:apachectl 现在是 apache2ctl 的别名

作为最佳实践，建议发出 sudo apache2ctl Graceful

正如其含义所示，graceful 参数提供了一种更稳定的方式来重新启动 apache 进程，让其子进程在重新加载配置之前完成正在进行的任务。

cf man apache2ctl

重新启动:

Restarts the Apache daemon by sending it a SIGHUP.

优雅:

Gracefully restarts the Apache daemon by sending it a SIGUSR1. If the daemon is not running, it is started. This differs from a normal restart in that currently open connections are not aborted.

Here is a reference about signalling SIGUSR1 as opposed to SIGHUP.
