For some odd reasons, the built-in Apache Server can’t no longer be started after I ran the 10.5.6 system update. As a result, “http://localhost/” fails to connect to the server. When I run the “sudo apachectl configtest” command, I got the following message:

dyld: Symbol not found: _apr_socket_sendfile
 Referenced from: /usr/sbin/httpd
 Expected in: /usr/lib/libapr-1.0.dylib

/usr/sbin/apachectl: line 81: 58838 Trace/BPT trap          $HTTPD -t

I did a good amount of searching on Google hoping to find related discussions on the same issue from other users, but I couldn’t find the right answers to my problem. This problem may or may not be related to my system setup, and trying to work with Apple to identify the cause can be time-consuming. I need the Apache Server to work now locally, and it becomes inevitable to re-install the default Apache Server on Leopard 10.5.6 as the quickest solution.

Thanks to the Internet and those generous code contributors, I find this very useful shell script from a CodeSnippets post that allows me to quickly re-install the latest version of Apache Server without figuring out a lot of thing on my own. Due to its usefulness, I am including it in my post just so I always have it even if it becomes unavailable on CodeSnippets in the future. The credit of this code certainly goes to its original code contributor.

# this re-installs the default apache server on leopard
# save code as filename.sh and give it permissions to run (see in code)
# run with ./apache_refresh.sh
# If permissions error do: chmod u+x filename.sh

Notice the line “curl -O http://www.gtlib.gatech.edu/pub/apache/httpd/httpd-2.2.11.tar.gz” that specifies the download source. Change that to the most current version if necessary.
