How to install PDO on Ubuntu Edgy
Since PDO should be enabled by default on PHP >= 5.1 but it isn’t on X/K/ubuntu edgy, I had to go through some forums and tutorials to learn how.
Firstly, install php-pear and some other dev packages:
sudo apt-get install php-pear php5-dev libmysqlclient15-dev
Then use the pecl command to install pdo && pdo_mysql:
sudo pecl install pdo sudo pecl install pdo_mysql
If you use a 64 bit system, an error message like
Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 143 bytes) in /usr/share/php/PEAR/Builder.php on line 312
probably will come out, and editing the php.ini files to increase the memory_limit size won’t work.
Instead, edit the /usr/share/php/pearcmd.php file adding
@ini_set('memory_limit', '16M');
Add the drivers to your /etc/php5/apache2/php.ini
extension=pdo.so extension=pdo_mysql.so
Restart your apache server:
sudo /etc/init.d/apache2 restart
Now you should be able to notice the pdo drivers installed in the phpinfo() page. Enjoy
