How to enable mysqli extension on redhat?

Question

My php.ini says:

Additional .ini files parsed

    /etc/php53/php.d/curl.ini,   
 /etc/php53/php.d/fileinfo.ini, /etc/php53/php.d/json.ini, /etc/php53/php.d/mysqli.ini,
 /etc/php53/php.d/mysql.ini, /etc/php53/php.d/pdo_mysql.ini, /etc/php53/php.d/phar.ini, 
/etc/php53/php.d/zip.ini

mysqli.ini is loaded.. But still i get this,

PHP Fatal error: Class 'mysqli' not found

• i tried enabling dynamic loading and initialize php scripts with dl("mysqli.so");

• i also tried recompiling the php source:

  ./configure --with-mysql=/usr/lib64/mysql --with-
  mysqli=/usr/lib64/mysql/mysql_config
  

even this didn't work. Can anybody help me solve my problem?

1. Red Hat Enterprise Linux Server release 5 (Tikanga).
2. x86_64 GNU/Linux.
3. No access to RHN.

Thanks.

Answer 1

If you're using php5.5.x then:

$ sudo yum install php55-mysqlnd

or:

$ yum install php[your version]-mysqli or mysql 

If you're greater than 5.3:

$ yum install php[your version]-mysqlnd

So... php -i and phpinfo() does not shown this module?

Check /etc/php53/php.d/mysqli.ini for extension="mysqli.so" Find your extension dir like "php -i|grep extension_dir" Check extension path for this module (for example: ls -lha /usr/lib64/php/modules/mysqli.so) If moudule exist, check all needed libs for this mod (ldd /usr/lib64/php/modules/mysqli.so) If module does not exist, install it. (i assume, you are custom compiling php, so u can find this extension in ext/mysqli of php source. Just make && make install it, or u see some errors during install) Also, you may find some usefull information about missing or incompatible modules in stdout from php -i.
