如何在 ubuntu 13.10 上启用 apache2-mpm-worker？

我正在尝试为 apache2 启用 apache2-mpm-worker - 但没有成功。为 ubuntu 13.10 安装和启用 apache2 mpm-working 的步骤是什么？是否有一些隐藏的设置可以说服不同的 apache？

apache2-mpm-worker 包只是一个依赖于 apache2 包的过渡包。该包具有 prefork、worker、itk 和 event MPM，如下所示数字存储示波器模块。

您可以在 mods-available 中看到它们

$ ls /etc/apache2/mods-available/mpm*
/etc/apache2/mods-available/mpm_event.conf  /etc/apache2/mods-available/mpm_prefork.conf
/etc/apache2/mods-available/mpm_event.load  /etc/apache2/mods-available/mpm_prefork.load
/etc/apache2/mods-available/mpm_itk.conf    /etc/apache2/mods-available/mpm_worker.conf
/etc/apache2/mods-available/mpm_itk.load    /etc/apache2/mods-available/mpm_worker.load

并查看 mods-enabled 中的活动

$ ls -l /etc/apache2/mods-enabled/mpm*
lrwxrwxrwx 1 root root 32 Mar 25 21:09 /etc/apache2/mods-enabled/mpm_event.conf -> ../mods-available/mpm_event.conf
lrwxrwxrwx 1 root root 32 Mar 25 21:09 /etc/apache2/mods-enabled/mpm_event.load -> ../mods-available/mpm_event.load

您可以使用以下方式禁用和启用模块a2dismod和a2enmod。
