How to install PHP PDO extensions on Debian Lenny


If you need to install PHP PDO extensions on Debian Lenny, its very
simple. This is what I did to get it done:

sudo aptitude install php5 php5-dev php5-cli libmysqlclient15-dev

Then use pecl to get PDO:

sudo pecl install pdo

Then, in case you want the PDO MySQL extension:

sudo pecl install pdo_mysql

update: I found out that PDO and mysqli drivers conflicted on my system and I ended up with none. To fix this, do pecl install mysql and then add on your php.ini like indicated below. This enables pdo and mysql driver, but I couldn’t get msyqli driver back on.

Then you have to edit /etc/php5/apache2/php.ini and add:

Also add this line only if you installed pdo_mysql.

Restart your web server with:

sudo invoke-rc.d apache2 restart

And that’s it. Enjoy your PDO extensions on Debian Lenny.

    Thanks for that hint but I found out that and are available in the lenny packages php-common and php5-mysql. – I think it’s easier to install and update the core packages than using pecl.

  2. sokai says:

    *damn* …the package name for is not “php-common” but php5-common! *sry*

  3. bmau says:

    You also need package libmysqlclient-dev if you want to install with pecl:
    apt-get install libmysqlclient-dev

    but much easier is to install as sokai pointed.

  4. Hi,
    I had problem in Debian Lenny saying “ is using a unsupported protocal – This should never happen.
    install failed”

    The solution is to delete /usr/share/php/.channels directory and run “pecl update-channels”
