Fatal error: Class 'LevelDB' not found

[rjonesx]

I am at a loss here...

I followed the installation instructions and encountered no errors. The "make test" was successful, but for some reason I get the following error every time I try to use...

$db = new LevelDB("location");

Fatal error: Class 'LevelDB' not found in /var/www/html/test.php on line 27

Am I missing an include?

More information...

1. The tests have worked perfectly, I have attached the results at the very bottom...
2. phpinfo() does not indicate that leveldb is installed... (http://198.101.8.230/phpinfo.php)
3. LevelDB is correctly in the /usr/lib64/php/modules/leveldb.so folder
4. Other .so in that folder are being dynamically included

Any ideas?

All relevant info I can provide is below:

found something really weird...

phpinfo() run via apache shows no leveldb phpinfo() run via command line does.

[2072]

This is probably a php.ini issue. Check which PHP ini is loaded in phpinfo()'s output.

[rjonesx]

both say /etc/php.ini

[rjonesx]

totally weird

[hwde]

Dumb question: you have reloaded the webserver (i.e. apachectl graceful) ?

[rjonesx]

Not a dumb question but, yes, multiple times. Rebooted the server, Reinstalled everything about 60 times. totally. weird.

[hwde]

I assume you looked at the error_log of the webserver too (tail -f path_to_error_log, i.e. /var/log/apache2/error_log) while restarting the apache?

[2072]

Make sure that you have an error_log defined in your php.ini also check your extension_dir setting:

example:

error_log = "/path/php_errors.log"

extension_dir = "/path/php/extensions/no-debug-non-zts-20090626"

[rjonesx]

Thank you for your continued help. Both versions (http://198.101.8.230/phpinfo.php) and command line have the same extension directory set. Ill make sure that php errors are logged too.

Now we are getting somewhere!

[26-Nov-2013 06:22:42] PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/leveldb.so' - libleveldb.so.1: failed to map segment from shared object: Permission denied in Unknown on line 0

This seems related to apache's startup user, does the user have access right to the liblevdbldb.so.1? or maybe SElinux related: http://www.xcnetwork.com/selinux-prevents-apache-from-starting-mod_jk.jsp

please check out which user apache run as. and try:

$ ldd /usr/lib64/php/modules/leveldb.so
to find out where is your libleveldb.so 
$  ll /path/to/your/libleveld.so

[rjonesx]

Crazy. I am on a completely different server now, also using CentOS 64 bit and have the exact same problem.

I turned off selinux and then changed ownership to apache:apache and that seemed to work. crossing my fingers.

thanks for your excellent work!

Good :)
