The Perfect Server - Debian Squeeze (Debian 6.0) With BIND, Dovecot & Nginx [ISPConfig 3] - Page 7
21 Install ISPConfig 3
Before you start the ISPConfig installation ensure that Apache is stopped because phpMyAdmin will have installed Apache as a dependency. Should Apache2 already be installed on the system stop it now:
and remove Apache's system startup links if you have not already done so in a previous step:
insserv -r apache2
Make sure that nginx is running:
If you have both Apache and nginx installed, the installer asks you which one you want to use: Apache and nginx detected. Select server to use for ISPConfig: (apache,nginx) [apache]:
Type nginx. If only Apache or nginx are installed, this is automatically detected by the installer, and no question is asked.
To install ISPConfig 3 from the latest released version, do this:
The next step is to run
php -q install.php
This will start the ISPConfig 3 installer. The installer will configure all services like Postfix, Dovecot, etc. for you. A manual setup as required for ISPConfig 2 (perfect setup guides) is not necessary.
root@server1:/tmp/ispconfig3_install/install# php -q install.php
The installer automatically configures all underlying services, so no manual configuration is needed.
You now also have the possibility to let the installer create an SSL vhost for the ISPConfig control panel, so that ISPConfig can be accessed using https:// instead of http://. To achieve this, just press ENTER when you see this question: Do you want a secure (SSL) connection to the ISPConfig web interface (y,n) [y]:.
You can then access ISPConfig 3 under http(s)://server1.example.com:8080/ or http(s)://192.168.0.100:8080/ ( http or https depends on what you chose during installation). Log in with the username admin and the password admin (you should change the default password and possibly edit the admin username after your first login):
If your browser indicates a 502 Bad Gateway error, just restart PHP-FPM and try the URL again:
It can take a couple of minutes for the control panel to be accessible. The system should be ready to be used except if you have an error in your mail.log then read the note below.
21.1 ISPConfig 3 Manual
In order to learn how to use ISPConfig 3, I strongly recommend to download the ISPConfig 3 Manual.
On about 300 pages, it covers the concept behind ISPConfig (admin, resellers, clients), explains how to install and update ISPConfig 3, includes a reference for all forms and form fields in ISPConfig together with examples of valid inputs, and provides tutorials for the most common tasks in ISPConfig 3. It also lines out how to make your server more secure and comes with a troubleshooting section at the end.
21.2 ISPConfig Monitor App For Android
With the ISPConfig Monitor App, you can check your server status and find out if all services are running as expected. You can check TCP and UDP ports and ping your servers. In addition to that you can use this app to request details from servers that have ISPConfig installed (please note that the minimum installed ISPConfig 3 version with support for the ISPConfig Monitor App is 18.104.22.168!); these details include everything you know from the Monitor module in the ISPConfig Control Panel (e.g. services, mail and system logs, mail queue, CPU and memory info, disk usage, quota, OS details, RKHunter log, etc.), and of course, as ISPConfig is multiserver-capable, you can check all servers that are controlled from your ISPConfig master server.

22 Additional Notes
22.1 It is likely that emails are not sent or received so to correct this follow the steps below.
Postfix/Dovecot - warning SASL: Connect to private/auth failed: No such file or directory
Error: Postfix/Dovecot - warning: SASL: Connect to private/auth failed: No such file or directory
Similar error messages will appear in your mail log (cat /var/log/mail.log):
Aug 23 15:55:01 server1 postfix/smtpd: warning: SASL: Connect to private/auth failed: No such file or directory
Solution (this config should already exist after this tutorial):
Open your dovecot.conf /etc/dovecot/dovecot.conf, and make sure you have the following lines in it:
Then check if /var/spool/postfix/private/auth got created:
ls -l /var/spool/postfix/private/auth
Also make sure you add the following line into your /etc/postfix/main.cf file, sensibly on the line next to readme_directory = /usr/share/doc/postfix and restart postfix.
If the Debian server that you have just set up in this tutorial is an OpenVZ container (virtual machine), you should do this on the host system, assuming that the ID of the OpenVZ container is 101, replace it with the correct VPSID on your system:
