I was installing ISPConfig3. I was able to complete all of the required steps until I actually start to install ispconfig from install.php file. When I type in the command "php -q install.php" it gives me the following errors. which: no apache in (/sbin:/user/sbin:/usr/local/sbin:/root/bin:/urs/local/bin:/bin:/usr/bin/X11:/usr/X11R6/bin:/opt/kde3/bin:/usr/lib/jv,/jre/bin:/usr/lib/mit/bin:/usr/lib/mit/sbin) also I get the same error repeated with the following in the place of "apache" and the same paths as mentioned above apache2, httpd, couriertcpd, saslauthd, amavisd-new, jk_chrootsh. when I continue with the installation it lets me enter the necessary information then it installs it but gives me the following error. PHP Warning: call-time pass-by-referance has been deprecated; If you would like to pass it by reference, modify the declaration of fsockopen(). if you would like to enable call-time pass-by-reference, you can set allow_call-time_pass_reference to true in your INI files in /usr/local/ispconfig/server/mods-available/monitor_core_module.inc.php on line 1236 this message is repeated again and then it is repeated twice again with the line number 1248 when I restart my computer it shows an error on xconsole saying "error connecting to MySQL server at localhost: can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) (errno=2) I have zero clue what's going on.
