The Perfect Server - OpenSUSE 12.1 x86_64 With Nginx [ISPConfig 3] - Page 6
19 Install SquirrelMail
To install the SquirrelMail webmail client, run:
zypper install http://download.opensuse.org/repositories/server:/php:/applications/openSUSE_12.1/noarch/squirrelmail-1.4.22-1.1.noarch.rpm
Then configure SquirrelMail:
/srv/www/htdocs/squirrelmail/config/conf.pl
We must tell SquirrelMail that we are using Dovecot:

While we have been building SquirrelMail, we have discovered some
preferences that work better with some servers that don't work so
well with others. If you select your IMAP server, this option will
set some pre-defined settings for that server.
Please note that you will still need to go through and make sure
everything is correct. This does not change everything. There are
only a few settings that this will change.
Please select your IMAP server:
bincimap = Binc IMAP server
courier = Courier IMAP server
cyrus = Cyrus IMAP server
dovecot = Dovecot Secure IMAP server
exchange = Microsoft Exchange IMAP server
hmailserver = hMailServer
macosx = Mac OS X Mailserver

SquirrelMail is located in the /srv/www/htdocs/squirrelmail directory, but we need it in the /usr/share/squirrelmail/ directory. Therefore we create a symlink:
ln -s /srv/www/htdocs/squirrelmail /usr/share/squirrelmail
In addition to that, we change the owner of the /srv/www/htdocs/squirrelmail/data/ directory to nobody:
chown nobody /srv/www/htdocs/squirrelmail/data/
After you have installed ISPConfig 3, you can access SquirrelMail as follows:
The ISPConfig apps vhost on port 8081 for nginx comes with a SquirrelMail configuration, so you can use http://server1.example.com:8081/squirrelmail or http://server1.example.com:8081/webmail to access SquirrelMail.
If you want to use a /webmail or /squirrelmail alias that you can use from your web sites, this is a bit more complicated than for Apache because nginx does not have global aliases (i.e., aliases that can be defined for all vhosts). Therefore you have to define these aliases for each vhost from which you want to access SquirrelMail.
To do this, paste the following into the nginx Directives field on the Options tab of the web site in ISPConfig:
location /squirrelmail {
root /usr/share/;
index index.php index.html index.htm;
location ~ ^/squirrelmail/(.+\.php)$ {
try_files $uri =404;
root /usr/share/;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include /etc/nginx/fastcgi_params;
fastcgi_buffer_size 128k;
fastcgi_buffers 256 4k;
fastcgi_busy_buffers_size 256k;
fastcgi_temp_file_write_size 256k;
fastcgi_intercept_errors on;
}
location ~* ^/squirrelmail/(.+\.(jpg|jpeg|gif|css|png|js|ico|html|xml|txt))$ {
root /usr/share/;
}
}
location /webmail {
rewrite ^/* /squirrelmail last;
}
|
If you use https instead of http for your vhost, you should add the line fastcgi_param HTTPS on; to your SquirrelMail configuration like this:
location /squirrelmail {
root /usr/share/;
index index.php index.html index.htm;
location ~ ^/squirrelmail/(.+\.php)$ {
try_files $uri =404;
root /usr/share/;
fastcgi_pass 127.0.0.1:9000;
fastcgi_param HTTPS on; # <-- add this line
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include /etc/nginx/fastcgi_params;
fastcgi_buffer_size 128k;
fastcgi_buffers 256 4k;
fastcgi_busy_buffers_size 256k;
fastcgi_temp_file_write_size 256k;
fastcgi_intercept_errors on;
}
location ~* ^/squirrelmail/(.+\.(jpg|jpeg|gif|css|png|js|ico|html|xml|txt))$ {
root /usr/share/;
}
}
location /webmail {
rewrite ^/* /squirrelmail last;
}
|
If you use both http and https for your vhost, you need to add the following section to the http {} section in /etc/nginx/nginx.conf (before any include lines) which determines if the visitor uses http or https and sets the $fastcgi_https variable (which we will use in our SquirrelMail configuration) accordingly:
vi /etc/nginx/nginx.conf
[...]
http {
[...]
## Detect when HTTPS is used
map $scheme $fastcgi_https {
default off;
https on;
}
[...]
}
[...]
|
Don't forget to reload nginx afterwards:
systemctl reload nginx.service
Then go to the nginx Directives field again, and instead of fastcgi_param HTTPS on; you add the line fastcgi_param HTTPS $fastcgi_https; so that you can use SquirrelMail for both http and https requests:
location /squirrelmail {
root /usr/share/;
index index.php index.html index.htm;
location ~ ^/squirrelmail/(.+\.php)$ {
try_files $uri =404;
root /usr/share/;
fastcgi_pass 127.0.0.1:9000;
fastcgi_param HTTPS $fastcgi_https; # <-- add this line
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include /etc/nginx/fastcgi_params;
fastcgi_buffer_size 128k;
fastcgi_buffers 256 4k;
fastcgi_busy_buffers_size 256k;
fastcgi_temp_file_write_size 256k;
fastcgi_intercept_errors on;
}
location ~* ^/squirrelmail/(.+\.(jpg|jpeg|gif|css|png|js|ico|html|xml|txt))$ {
root /usr/share/;
}
}
location /webmail {
rewrite ^/* /squirrelmail last;
}
|
20 ISPConfig 3
Before we install ISPConfig 3, make sure that the /var/vmail/ directory exists:
mkdir /var/vmail/
Before you start the ISPConfig installation, make sure that Apache is stopped (if it is installed - it is possible that some of your installed packages have installed Apache as a dependency without you knowing). If Apache2 is already installed on the system, stop it now...
systemctl stop apache2.service
... and remove Apache's system startup links:
systemctl disable apache2.service
Make sure that nginx is running:
systemctl restart nginx.service
(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.)
Download the current ISPConfig 3 version and install it. The ISPConfig installer will configure all services like Postfix, Dovecot, etc. for you. A manual setup as required for ISPConfig 2 is not necessary anymore.
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]:.
cd /tmp
wget http://www.ispconfig.org/downloads/ISPConfig-3-stable.tar.gz
tar xfz ISPConfig-3-stable.tar.gz
cd ispconfig3_install/install/
Now start the installation process by executing:
php -q install.php
server1:/tmp/ispconfig3_install/install # php -q install.php

Clean up the /tmp directory:
cd /tmp

rm -f /tmp/ISPConfig-3-stable.tar.gz
Afterwards you can 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 after your first login):
If you want to use IPv6 addresses with your nginx vhosts, please do the following before you create IPv6 vhosts in ISPConfig:
Open /etc/sysctl.conf...
vi /etc/sysctl.conf
... and add the line net.ipv6.bindv6only = 1:
[...] net.ipv6.bindv6only = 1 |
Run...
sysctl -p
... afterwards for the change to take effect.
20.1 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.
20.2 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 3.0.3.3!); 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.
For download and usage instructions, please visit http://www.ispconfig.org/ispconfig-3/ispconfig-monitor-app-for-android/.
