Apache

After an upgrade from Lucid to Precise, my PHP install started complaining about a library:

PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php5/20090626+lfs/gd.so'

While I've got a hunch that the actual problem is related to issues I had during the upgrade, turning this error (and other similar ones) off is as simple as going into /etc/php5/conf.d and renaming the file, in this case gd.ini to something like gd.ini.bak.

On a server I am working on right now, I installed a PHP application and attempted to run it. However, I ran into a "500 Internal Server Error". Upon further investigation by checking the logs, I found the following errors in the Apache error log:

SoftException in Application.cpp:357: UID of script "/home/foo/public_html/index.php" is smaller than min_uid
Premature end of script headers: index.php

PHP provides a number of different versions for install in Windows. There are versions which are tagged with VC6 and other with VC9. There are also thread-safe and non-thread-safe versions of the installer available for download. After some digging and trial & error fiddlery, my conclusion is that VC9 and non-thread-safe are for the Microsoft IIS webserver while the VC6 and thread-safe installers are for Apache and other non-IIS webservers.

Hope this helps :)

When (re)installing httpd today, I ran into the following error message:
(OS 10048)Only one usage of each socket address (protocol/network address/port) is normally permitted.
: make_sock: could not bind to address 0.0.0.0:80

While trying to check the vhost configuration on my Kubuntu dev box, I had to run httpd -S. Of course, since ubuntu renamed httpd to apache (a bit like calling a Veyron a Bugatti), I had to run apache2 -S. This however led to the following error message:
apache2: bad user name ${APACHE_RUN_USER}

Server: Apache 2.0.52 + SVN 1.4.3 + mod_dav_svn enabled. Most repositories also use a bunch of post commit hooks to automate tasks.
Client: Eclipse 3.2.2 + stock subclipse callisto install.

Error message:

commit -m "commit message." files
RA layer request failed
svn: Commit failed (details follow):
svn: PROPFIND request failed on '/repo/path/!svn/vcc/default'
svn: PROPFIND of '/repo/path/!svn/vcc/default': Could not read status line: connection was closed by server. (http://example.com)

Setting up apache 2 on my Kubuntu box lead to the following error whenever I restarted the daemon:

apache2: Could not determine the server's fully qualified domain name, using 127.0.1.1 for ServerName

The fix is to edit the conf file and add in the ServerName setting (as the error message requests). In other words,

sudo vi /etc/apache2/httpd.conf

followed by adding the following string:,

# ServerName is to be specified to avoid warning during reload
ServerName MYSERVER

I am not entirely sure about the status of the httpd.conf (vs. apache2.conf where the above line can also be inserted) file in Debian based distros.. Is it deprecated or something?
