The Perfect Server - Ubuntu Natty Narwhal (Ubuntu 11.04) [ISPConfig 2] - Page 7
To install webalizer, just run
apt-get install webalizer geoip-database
20 Synchronize the System Clock
It is a good idea to synchronize the system clock with an NTP (network time protocol) server over the internet. Simply run
apt-get install ntp ntpdate
and your system time will always be in sync.
21 Install Some Perl Modules Needed By SpamAssassin (Comes With ISPConfig)
apt-get install libhtml-parser-perl libdb-file-lock-perl libnet-dns-perl libnetaddr-ip-perl perl-modules
The configuration of the server is now finished, and if you wish you can now install ISPConfig on it. Please check out the ISPConfig installation manual: http://www.ispconfig.org/manual_installation.htm
Before you install ISPConfig, there's one important thing you must do. Open /usr/include/stdio.h and replace getline with parseline in line 671:
[...] This function is not part of POSIX and therefore no official cancellation point. But due to similarity with an POSIX interface or due to the implementation it is a cancellation point and therefore not marked with __THROW. */ extern _IO_ssize_t parseline (char **__restrict __lineptr, size_t *__restrict __n, FILE *__restrict __stream) __wur; #endif [...]
If you don't do this, the installation will fail because of the following error:
htpasswd.c:101: error: conflicting types for 'getline'
/usr/include/stdio.h:671: note: previous declaration of 'getline' was here
make: *** [htpasswd.o] Error 1
make: Leaving directory `/home/ISPConfig-2.2.stable/install_ispconfig/compile_aps/apache_1.3.41/src/support'
make: *** [build-support] Error 1
make: Leaving directory `/home/ISPConfig-2.2.stable/install_ispconfig/compile_aps/apache_1.3.41'
make: *** [build] Error 2
ERROR: Could not make Apache
You can undo the change to /usr/include/stdio.h after the successful ISPConfig installation (but don't forget to change it back whenever you want to update ISPConfig!).
22.1 A Note On SuExec
If you want to run CGI scripts under suExec, you should specify /var/www as the home directory for websites created by ISPConfig as Ubuntu's suExec is compiled with /var/www as Doc_Root. Run
and the output should look like this:
root@server1:~# /usr/lib/apache2/suexec -V
So if you want to use suExec with ISPConfig, don't change the default web root (which is /var/www) if you use expert mode during the ISPConfig installation (in standard mode you can't change the web root anyway so you'll be able to use suExec in any case).
