本文教你如何在 Ubuntu 16.04 上安装 Apache、PHP、MySQL、PureFTPD、BIND、Postfix、Dovecot 和 ISPConfig 3.1 搭建一个网站、邮件、邮件列表、DNS和FTP服务器。ISPConfig 3是一个虚拟主机控制面板，使您可以通过网络浏览器配置以下服务：Apache 或 nginx web 服务器，Postfix 电子邮件服务，Courier 或 Dovecot IMAP/POP3 服务，MySQL，BIND 或 MyDNS 域名服务，PureFTPd，SpamAssassin，ClamAV，等等和更多的服务。
注意：本教程中使用的ISPConfig 3.1版目前正处于测试状态下，ISPConfig 3.1 最终将在2016年6月发布，旧的 ISPConfig old stable 3.0.5p9 无法在 Ubuntu 16.04 中使用，而且不兼容PHP 7。
1.初步说明
在本教程中，使用的IP地址为192.168.1.100和网关192.168.1.1主机名server1.example.com。这些设置可能与你的不同，所以你必须根据你的情况更换。进一步讨论之前，你需要有一个基本的最小安装。
2. 编辑 /etc/apt/sources.list 并更新 Linux。
编辑/etc/apt/sources.list。注释掉或从文件中删除安装光盘，并确保库启用。应该是这样设置：
nano /etc/apt/sources.list
内容如下：
#
# deb cdrom:[Ubuntu-Server 16.04 LTS _Xenial Xerus_ – Release amd64 (20160420)]/ xenial main restricted
#deb cdrom:[Ubuntu-Server 16.04 LTS _Xenial Xerus_ – Release amd64 (20160420)]/ xenial main restricted
# See for how to upgrade to
# newer versions of the distribution.
deb xenial main restricted
# deb-src xenial main restricted

deb xenial-security main restricted
# deb-src xenial-security main restricted
deb xenial-security universe
# deb-src xenial-security universe
deb xenial-security multiverse
# deb-src xenial-security multiverse
然后运行：
apt-get update
更新apt软件包和数据库：
apt-get upgrade
安装最新的更新（如果有的话）。如果你看到一个新的内核被安装作为更新的一部分，重新引导系统：
reboot
3.更改默认的shell
dpkg-reconfigure dash
Use dash as the default system shell (/bin/sh)?
如果你不这样做，ISPConfig安装会失败。
