GLIBCXX error in php

[Colster]

Our webserver has been working fine for months but sunday it stopped running.

Its a rented dedicated server we use for gaming but we have a webserver running on there for stats (psychostats)

When the webserver stopped I went in using SSH and tried

service httpd restart

and I get the following error:

Starting httpd: Syntax error on line 6 of /etc/httpd/conf.d/php.conf:
Cannot load /etc/httpd/modules/libphp5.so into server: /lib/libstdc++.so.6: version `GLIBCXX_3.4.4' not found (required by /usr/lib/libaspell.so.15)
[FAILED]


I uninstalled and reinstalled httpd using yum and the webserver works again, until i install php (yum install httpd-php) then same error.

running ls -al /usr/lib/libstdc++.so.6 gets me:

lrwxrwxrwx 1 root root 18 Mar 23 20:01 /usr/lib/libstdc++.so.6 -> libstdc++.so.6.0.7*

and rpm -q --provides libstdc++ gives the following:

libstdc++.so.6
libstdc++.so.6(CXXABI_1.3)
libstdc++.so.6(CXXABI_1.3.1)
libstdc++.so.6(GLIBCXX_3.4)
libstdc++.so.6(GLIBCXX_3.4.1)
libstdc++.so.6(GLIBCXX_3.4.2)
libstdc++.so.6(GLIBCXX_3.4.3)
libstdc++.so.6(GLIBCXX_3.4.4)
libstdc++.so.6(GLIBCXX_3.4.5)
libstdc++.so.6(GLIBCXX_3.4.6)
libstdc++.so.6(GLIBCXX_3.4.7)
libstdc++34
libstdc++ = 4.0.2-8.fc4


..so it looks like the files are all there but still the error remains, I found a link on the net that suggested installing libsigc++20 which I tried but that didnt solve it, our GSP have said that they can't fix it either.

Would a reinstall of FC4 (or maybe FC5) be the only solution?

What's in /etc/httpd/conf.d/php.conf?
What's the output of updatedb
locate libphp5.so?

Thanks for the help

Can you post the output of httpd -V?

(Depending on your Apache version, the command might also be
httpd2 -V.)

[Colster]

Thanks, I tried both v and V just in case but I guess it's the second one you want.

Please post the output of ls -la /etc/httpd

[Colster]

OK, that returns:

lrwxrwxrwx 1 root root 27 Mar 23 19:12 modules -> ../../usr/lib/httpd/modules/
Your Apache expects the modules in /usr/lib/httpd/modules/, but you have libphp5.so here:
/usr/local/apache2/modules/libphp5.so
/downloads/php-5.0.4/.libs/libphp5.so
/downloads/php-5.0.4/libs/libphp5.so

You can try to copy one of them to /usr/lib/httpd/modules/, e.g.:
cp /usr/local/apache2/modules/libphp5.so /usr/lib/httpd/modules/
Restart Apache afterwards.

OK tried this and it said did i want to overwrite existing so there was one there, I did this and started httpd and no error but php pages would not display or I got message saying Version 5.0.4 didnt have mysql support installed.

Although I had done yum install php-mysql

Uninstalled and reinstalled php and the error returns.

If I try copying the file again it again gives the overwrite warning

Did you enable the MySQL extension in your php.ini?

[Colster]

Did you enable the MySQL extension in your php.ini?


IIRC That version of php has it enabled by default


Note that MySQL and ODBC support is now built in

[falko]

Please create this file:
<?php
phpinfo();
?>
and put it in a PHP-enabled web on your server and access it with your browser. Is MySQL mentioned anywhere in the output?

[Colster]

Thats the problem, as soon as I enable php on the webserver it won't start.

If I try what u suggest it just displays the code, if i copy the module from apache2 i don't get the error but only because php doesnt load then anyway

I think the error is more linked to /lib/libstdc++.so.6: version `GLIBCXX_3.4.4' not found than php itself

[falko]

Have you tried /downloads/php-5.0.4/libs/libphp5.so (i.e. copy it to /usr/lib/httpd/modules/ and restart Apache).

[Colster]

Yes, it gives the same problem, httpd starts ok but basically php doesnt work.

the phpinfo test page just downloads, opens wordpad and shows

<?php
phpinfo();
?>

[falko]

Does your server do automatic updates, or has it been hacked? It's strange that this error occurred from one day to the other...
Which distribution do you use?

[Colster]

Its fedora core 4, i suppose hacking is possible, rkhunter doesn't find anything tho apart from the error already mentioned coming up in its logs too.

Also tried reinstalling aspell but no change

[falko]

Can you find a cron job that does automatic updates?
