Apache (PHP) fails to start

[musv]

Hi there,

after the last system update my apache refuses to start. There are no vhosts, nothing professional. It's a simple home net configuration, which means, it's the default configuration.

you may follow the migration, changes listed in this bugreport: https://bugs.gentoo.org/show_bug.cgi?id=410607

i.e.: undefined symbol: unixd_config

-> needs in httpd.conf: LoadModule unixd_module modules/mod_unixd.so

I have just hit this problem despite reading this thread first and following the advice! I still get:

No solution as yet, I am still using apache-2.2.23. The failing version is 2.4.3; php is 5.3.15.

I found that the /usr/lib/apache2/modules/libphp5.so was soft linked to the a non existent file.
ls -l /usr/lib/apache2/modules/libphp5.so
lrwxrwxrwx 1 root root 34 Mar 15 2011 /usr/lib/apache2/modules/libphp5.so -> /usr/lib/php5.3/apache2/libphp5.so
It seems that upon upgrading to php5.4 this link was not changed once I linked to the right file I was able to start apache2.

ls -l /usr/lib/apache2/modules/libphp5.so
lrwxrwxrwx 1 root root 50 Dec 20 15:28 /usr/lib/apache2/modules/libphp5.so -> /usr/lib/php5.4/usr/lib/apache2/modules/libphp5.so

I seem to have both php-5.3 and php-5.4 installed. I will try changing the link and see what happens. Thanks for the tip!

You can use "eselect php list" to choose which php to use, I found out. However, neither works for me, I still get the error. Apache-2.3 is hard-masked now on my system.

I had this problem with Apache 2.4.3 and PHP 5.4.9. The solution was to re-build PHP.

Did you actually re-build PHP or just rely on revrep-rebuild to check consistency?

I had this problem with apache 2.4.6-r2 and php-5.5.2. Doing

[sunhaowei]

I also encounter this problem
Cannot load modules/libphp5.so into server: /opt/rh/httpd24/root/etc/httpd/modules/libphp5.so: undefined symbol: unixd_config
httpd24 and php5.5.23

same problem here, I reinstalled apache and php

[Syl20]

Which USE flags did you use for apache and php ?

[Krog]

[Syl20]

Certainly a dumb question, but... As you show the USE flags for php _5.5_, are you sure you recompiled php _5.6_ after upgrading apache ?

[Krog]

[Krog]

SOLVED! thanks!!
I also had to add "ServerName localhost" to my httpd.conf to suppress a warning
strange that emerge @preserved-rebuild or revdep-rebuild did not complain about this, or portage did not offered an upgrade or downgrade of php 5.6...
probably would be a good idea to let portage automatically rebuild php after an update of apache

[Syl20]

dev-lang/php-5.6.17 has been removed from portage, so the message from emerge is normal.
Have a look on your world file and on your package.mask file(s), maybe there are some limitations on the 5.6 versions.

If you don't use it, you should unmerge php 5.5.

Concerning the auto-update of php after apache, why not, but, in your case, the problem was the update from apache 2.2.x to apache 2.4.x. Minor versions updates don't need so much care.
