Configuration Files
This section describes configuration files that ZoneMinder uses beyond the
various Web UI options.



System Path Configurations
At one point of time, ZoneMinder stored various system path configurations
under the Web UI (Options->Paths). This was removed a few versions ago and
now resides in a configuration file. The motivation for this change can be
read in this discussion.

Typically, path configurations now reside in /etc/zm.
Here is an example of the file hierarchy:
/etc/zm
├── conf.d
│   ├── 01-system-paths.conf
│   ├── 02-multiserver.conf
|   ├── 03-custom.conf #optional
│   └── README
├── objectconfig.ini # optional
├── zm.conf
└── zmeventnotification.ini #optional



The roles of the files are as follows:

zm.conf contains various base configuration entries. You should not edit
this file as it may be overwritten on an upgrade.
zmeventnotification.ini is only present if you have installed the
ZoneMinder Event Notification Server.
objectconfig.ini is only present if you have installed the machine
learning hooks for the Event Notification Server.
conf.d contains additional configuration items as follows:
	

01-system-paths.conf contains all the paths that were once part of
Options->Paths in the Web UI. You should not edit this file as it may be
overwritten on an upgrade
02-multiserver.conf file consists of custom variables if you are
deploying ZoneMinder in a multi-server configuration (see Multi-Server
Install)
03-custom.conf is an custom config file that I created to override
specific variables in the path files. This is the recommended way to
customize entries. Anything that you want to change should be in a new file
inside conf.d. Note that ZoneMinder will sort all the files alphabetically
and run their contents in ascending order. So it doesn’t really matter
what you name them, as long as you make sure your changes are not
overwritten by another file in the sorting sequence. It is therefore good
practice to prefix your file names by nn- where nn is a monotonically
increasing numerical sequence 01- 02- 03- and so forth, so you know the
order they will be processed.
	




Timezone Configuration
Earlier versions of ZoneMinder relied on php.ini to set Date/Time Zone. This
is no longer the case. You can (and must) set the Timezone via the Web UI,
starting ZoneMinder version 1.34. See here.
Database Specific Configuration



Todo
do we really need to have this section? Not sure if its generic and not
specific to ZM

While the ZoneMinder specific database config entries reside in
/etc/zm/zm.conf and related customizations discussed above, general database
configuration items can be tweaked in /etc/mysql (or whichever path your DB
server is installed)
