Localhost offline after upgrade

After an upgrade from Tiger to Snow Leopard the localhost is not responding anymore.

Apple support has run an ACCD on my machine and concluded that the Apache upgrade has failed.
Apple support told me they do not have a support document that describes how to reset/ reinstall Apache. They can tell me that when I reinstall Apache myself, I loose support (hmmm).

Caught between two fires: can anyone tell me how I reset/ reinstall Apache on SL (without forcing me to do a clean SL install).

Regards,
Coen

What is it not doing that the Apple tech says the upgrade has failed. And what Apache upgrade?

To be more specific (thanks for reminding me).

When using a webbrwoser to connect to my localhost I get the message "Safari can't open the page http://localhost/" because Safari can't connect to the server 'localhost'".

My MBP came with Tiger. I installed PHP and MySQL on it as well. Have used localhost for 2 years without problems.
This weekend I purchased SL and ran the install. The eintire upgrade went well without issues.

Only my Localhost is not working. Obviously PHP and MySQL don't work either.

Are you running Apple's built-in Apache server or are you using one provided by the same source as your PHP/MySQL?

If using Apple's, what does this terminal command report?

apachectl configtest

localhost is a special name for your own machine, almost always mapping to the IP address 127.0.0.1.

If you cannot connect to "localhost" it's either because a web server is not running on your machine or connections are prohibited via the loopback interface.

Per update I was running the Apache that was part of Tiger. Php and MySQL were installed by myself.

I performed a "standard" upgrade to SL. (just insert disc and sit back).

I presume SL Apache has been installed. I did nothing (yet) to php and mysql.

Both localhost and 127.0.0.1 do not return a response.

I have no idea how to install Apache, besides re-installing OS X. However, I don't think that is your problem. Run the command I posted above and let us know what the configtest reported.

Note also that in Leopard and Snow Leopard the method of configuring apache changed such that config files that used to live in /etc/httpd now live in /etc/apache2.

Barney,

I ran the command

apachectl configtest

This is the result:

d-essence:~ dessence$ apachectl configtest
httpd: Syntax error on line 459 of /private/etc/apache2/httpd.conf: Syntax error on line 15 of /private/etc/apache2/extra/httpd-userdir.conf: Syntax error on line 8 of /private/etc/apache2/users/+entropy-php.conf: Cannot load /usr/local/php5/libphp5.so into server: dlopen(/usr/local/php5/libphp5.so, 10): no suitable image found. Did find:\n\t/usr/local/php5/libphp5.so: no matching architecture in universal wrapper

An error. I have no clue what it means.

It means that it can't find the php library that the config file is telling it to load.

You could try to reload whatever you did to install php, or you could use Apache's default library at: libexec/apache2/libphp5.so.

The config files are just text files that can be edited with any text editor. I use TextWrangler because it lets me authenticate the file to edit.

You need to edit the /etc/apache2/users/+entropy-php.conf file and change the line that has this:

LoadModule php5_module /usr/local/php5/libphp5.so

to

LoadModule php5_module libexec/apache2/libphp5.so

You'd probably be better off getting help from the people who created the php installer you used.

Barney,

I will try the change and report.

About the install: the funny thing is I did NOT install PHP on SL. The PHP files are from the Tiger install. In the upgrade to SL the installer failed to upgrade my former PHP (Tiger) references).

Apple Support tells me that the SL upgrade installer IS capable of upgrading Apache, but if you have 3rd party code like PHP and/ or MySQL, the installer fails. As I have witnessed.

Going to try your change now.

Barney,

Bingo. It works.

Apache and PHP working fine. Thanks.

I will start a separate thread for a error code 2002 issue with the socket for MySQL.

Warning: mysql_connect() [function.mysql-connect]: [2002] No such file or directory (trying to connect via unix:///tmp/mysql.sock) in /Users/dessence/Sites/dessence/sql/dbinfo.inc.php on line 5

Do a search for snow leopard entropy php mysql.

When I was looking for a better tutorial, I found some blogs and discussions that talked about how to fix the MySQL socket.

Also, entropy php was not part of Tiger. It probably came along with MySQL.
