Please ensure, that PHP support is either builtin or installed for the following PHP extension modules:
mysql (For configuration, see note below)
SNMP (For configuration, see note below)
LDAP (Required only when using LDAP authentication)
GD (Required only for some Plugins)
You may run the following command to get the list of all available PHP modules
Please verify, that the modules are installed and configured correctly. There are several ways to do so, please consult PHP configuration instructions for a complete description.
We will continue using the most recommended way of configuring php extension modules. Please find the file /etc/php.ini and make the following changes to it:
extension_dir = /etc/php.d
This will enable PHP to find more configuration directives in that very directory. Other distros point to /usr/lib/php/modules instead. In each case, you should locate e.g. mysql.so in that directory.
Activate the MySQL extension via /etc/php.d/mysql.ini
; Enable mysql extension module extension=mysql.so
Activate the SNMP extension via /etc/php.d/snmp.ini
; Enable snmp extension module extension=snmp.so
If you want to allow template importing, uncomment the following line:
file_uploads = On
