The Perfect Server - Ubuntu Maverick Meerkat (Ubuntu 10.10) [ISPConfig 2] - Page 7

19 Webalizer

To install webalizer, just run 

aptitude 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 

aptitude install ntp ntpdate

and your system time will always be in sync.

 

21 Install Some Perl Modules Needed By SpamAssassin (Comes With ISPConfig)

Run

aptitude install libhtml-parser-perl libdb-file-lock-perl libnet-dns-perl libnetaddr-ip-perl libarchive-tar-perl

 

22 ISPConfig

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: 

vi /usr/include/stdio.h
[...]
   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[2]: *** [htpasswd.o] Error 1
make[2]: Leaving directory `/home/ISPConfig-2.2.stable/install_ispconfig/compile_aps/apache_1.3.41/src/support'
make[1]: *** [build-support] Error 1
make[1]: 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

 /usr/lib/apache2/suexec -V

and the output should look like this:

root@server1:~# /usr/lib/apache2/suexec -V
 -D AP_DOC_ROOT="/var/www"
 -D AP_GID_MIN=100
 -D AP_HTTPD_USER="www-data"
 -D AP_LOG_EXEC="/var/log/apache2/suexec.log"
 -D AP_SAFE_PATH="/usr/local/bin:/usr/bin:/bin"
 -D AP_UID_MIN=100
 -D AP_USERDIR_SUFFIX="public_html"
root@server1:~#

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).
