如何卸载作为乘客安装的一部分安装在Ubuntu 11.04上的nginx？
我应该只使用gem uninstall passenger吗？这会同时删除nginx吗？
这是我运行apt-get remove时看到的结果：

sudo apt-get remove nginx-common nginx-full
Reading package lists... Done

**Package nginx-common is not installed, so not removed
Package nginx-full is not installed, so not removed**
The following packages were automatically installed and are no longer required:
  nspluginwrapper linux-headers-2.6.38-13-generic libmysqlclient-dev libaprutil1-ldap libaprutil1-dev libmysqlclient16 libdb4.8-dev libaprutil1-dbd-sqlite3
  apache2.2-bin linux-headers-2.6.38-14-generic linux-headers-2.6.38-12 linux-headers-2.6.38-13 linux-headers-2.6.38-14 mysql-common linux-headers-2.6.38-12-generic
Use 'apt-get autoremove' to remove them.
