如何在 Ubuntu 上安装 Webmin

Webmin 是一个基于 Web 的 Unix 系统管理界面。使用任何现代 Web 浏览器，您都可以设置用户帐户、Apache、DNS、文件共享等等。Webmin 无需手动编辑 Unix 配置文件（如 /etc/passwd），并且允许您从控制台或远程管理系统。本文将向您介绍如何在 Ubuntu 上安装 Webmin。

要安装 Webmin，请打开 /etc/apt/sources.list 文件，如下所示：

# sudo nano /etc/apt/sources.list

文件的示例输出应如下所示：

# deb cdrom:[Ubuntu 14.04.4 LTS _Trusty Tahr_ - Release amd64 (20160217.1)]/ trusty main restricted

# See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to
# newer versions of the distribution.
