Comment from Tom Lobato
It`s worth to comment that the error:
—————————————————–
mobile:~# php /usr/share/cacti/site/poller.php
Fatal error: Call to undefined function: mysql_pconnect() in
/usr/share/php/adodb/drivers/adodb-mysql.inc.php on line 367
—————————————————–
is not solved in debian etch (at least) with the instruction above. I had to tell
php CLI to load mysql.so to get it working.
In my case, I created the file /etc/php5/cli/conf.d/mysql.ini and added the line:
extension=mysql.so
Remember, “your mileage may vary”, maybe you have to add this line in another file,
study your distribution and version.
After this, I get:
—————————————————–
mobile:~# php /usr/share/cacti/site/poller.php
