After my box received an auto update today, apache was restarted, and this caused a problem with php sites connecting to mysql.
The sites error log was showing this for each attempted connection:
PHP Fatal error: Call to undefined function: mysql_pconnect() in /home/....
The /etc/php.d/mysql.ini file was present, correct and being included (according to a php_info() page. (additional .ini files parsed /etc/php.d/imap.ini, /etc/php.d/ldap.ini, /etc/php.d/mysql.ini)
Yet mysql's module was not being loaded (no mysql section on page, and the error above).
The only update I received today was one to fix yesterdays permissions problem (which I'd already fixed and is unrelated to this one), so I looked to the previous days upgrade of php from 4.3.8 to 4.3.9.
The /etc/php.ini file in 4.3.8 had:
; Directory in which the loadable extensions (modules) reside.
extension_dir = /usr/lib/php4
Present so it was ok, yet the 4.3.9 rpm's (and my current) php.ini file had:
; Directory in which the loadable extensions (modules) reside.
extension_dir = "./"
To verify this was incorrect, I tailed the /var/log/httpd/error_log file and saw this when I restarted apache.
PHP Warning: Unknown(): Unable to load dynamic library './imap.so' - ./imap.so: cannot open shared object file: No such file or directory in Unknown on line 0
PHP Warning: Unknown(): Unable to load dynamic library './ldap.so' - ./ldap.so: cannot open shared object file: No such file or directory in Unknown on line 0
PHP Warning: Unknown(): Unable to load dynamic library './mysql.so' - ./mysql.so: cannot open shared object file: No such file or directory in Unknown on line 0
Simply changing the extension_dir to /usr/lib/php4 (and checking the files were in that folder) and restarting apache (service httpd restart) all was good again.
Again I hope this change is correct, and might help others if their boxes exhibit the same errors. (I'm on Redhat9 by the way.)
Not quite sure whats going on with the updates lately. Do you guys need more testers ?
Thanks again,
