在Ubuntu中启用Apache2模块

导论

每次在Ubuntu上配置Apache2时，我总会纠结于”哎呀？怎么操作来着？”，所以我在这里记下备忘录。

每次都忘記的我（帶著警示推動著）。

「a2enmod 了！你想起来了吗？」

Which module(s) do you want to enable (wildcards ok)?

谢谢交互式互动！

他正在亲切地询问想要启用哪个模块。

你想启用mod_rewrite吗？输入”rewrite”并按Enter键。

...

rewrite
Enabling module rewrite.
To activate the new configuration, you need to run:
  service apache2 restart

他一直在引导我重新启动，真是个非常友好的家伙。

$ sudo service apache2 restart

不需要互动也可以吗？我明白了。

$ sudo a2enmod rewrite
$ sudo service apache2 restart

禁用模块

顺便提一下无效化。

$ sudo a2dismod
