PHP and MySql problems!

I just upgraded to Redhat Linux 8, and installed everything(apache,php and mysql) off of the install of Redhat 8. Everything is working fine except when I try to access the mysql from a PHP script. I get the Fatal error: Call to undefined function: mysql_connect() . I reinstalled Apache and MySql and all the configure options were correct. However how can I remove PHP so that I can then reinstall it, I did this and it was still using the old PHP version 4.2.2 instead of the one just installed. Also is the reinstalltion of PHP neccessary as when I use the phpinfo() function in a php script, in the results I get this --with-mysql=shared,/usr. That seems to lead me to believe that PHP is compiled with MySql. I have searched and searched google for something that applies to this case and am starting to run out of ideas. Any help would be greatly appreciated.

Is MySql running? Do A

/etc/rc.d/init.d/mysqld status

See if it shows it as running. If not do a .

chkconfig mysqld on

then do a

/etc/rc.d/init.d/mysqld start

Try it then. Mysql is not running by default.

I'm having the same problem (RedHat 8, Apache, PHP, MySql). MySql is running on my machine.
Same error when I try to access the mysql from a PHP script. Any help would be greatly appreciated
