Still get error Unable to load dynamic library '/home/max/mongo/bin/mongo'

Question

I opened package and installed mongoDB and got:

[root@feeder /]# cd /home/max/mongodb-linux-i686-2.4.3/bin
[root@feeder bin]# ls -l
total 231700
-rwxr-xr-x 1 root root 17828204 Apr 23 00:01 bsondump

-rwxr-xr-x 1 root root 17832268 Apr 22 23:59 mongotop

• Added link: mongo -> mongodb-linux-i686-2.4.3

• Created data folder: mkdir /mongo/data

• initiated mongo: mongo/bin/mongod --dbpath=mongo/data

All works fine and can connect with mongoVUE monitor tool.

So far so good.

Now, I try to connect to BongoDB from PHP:

I added to php.ini (nano /etc/php.ini): extension=/home/max/mongo/bin/mongo

and restarted httpd: /etc/init.d/httpd restart

from code:

$conn = new Mongo('localhost');

I get an error:

PHP Warning: PHP Startup: Unable to load dynamic library '/home/max/mongo/bin/mongo' - /home/max/mongo/bin/mongo: wrong ELF class: ELFCLASS32 in Unknown on line 0

PS

I tried also: extension=/home/max/mongo/bin/mongo.so but still get the same error.

Did I miss something?

Additional Info from phpinfo()

• PHP Version => 5.3.16
• MongoDB: mongodb-linux-i686-2.4.3
• OS: CentOS release 5.2 (Final)

Please, help

Thanks,

[EDIT] I have PHP 64 bit, according to Farkie, I installed bongoDB 64 bit. Still get error but without "worng ELF":

 php -i | grep mongo

PHP Warning: PHP Startup: Unable to load dynamic library '/home/max/mongo/bin/mongo' - /home/max/mongo/bin/mongo: cannot dynamically load executable in Unknown on line 0

I don't see mongo.so under /usr/lib64/php/modules/

Answer 1

This is not how you configure PHP for Mongo. Read the documentation and you'll find out that there is a specific PHP extension you have to build.

Answer 2

You have a 64bit mongo.so, but a 32bit version of PHP (Or the other way round).
