I just installed zoneminder 1.35.16 on Ubuntu 20.04, without any issues, it seemed. Once installed, I migrated the newly created DB to a mysql VM where I keep most DB's. Zoneminder starts, I can add cameras, etc... but when I try to create a zone, nothing happens. The log states:

Code: Select all

Can't insert event: The user specified as a definer ('debian-sys-maint'@'localhost') does not exist. sql was (INSERT INTO Events ( MonitorId, StorageId, Name, StartDateTime, Width, Height, Cause, Notes, StateId, Orientation, Videoed, DefaultVideo, SaveJPEGs, Scheme ) VALUES ( 1, 2, 'New Event', from_unixtime( 1608431738 ), 2560, 1440, 'Continuous', '', 1, 1, 0, '', 3, 'Medium' ))  zm_event.cpp	line 111

I no longer have a mysql server on the zoneminder host, so I'm not really sure where zoneminder is getting this user from, aside from /etc/mysql/debian.cnf. Why would zoneminder be ignoring the zm.conf file for some DB calls?

I'm assuming I copied something over with the DB that includes this user, for whatever reason, so I did some searching and learned that some table views have a definer. If this is the issue, how do I find out? I tried a few commands I'd found online, but they listed 0 views in the DB.

Not sure where to go next. Any help would be appreciated.

nano /etc/zm/zm.conf

ZM_DB_HOST=192.168.50.2

Make sure the ZM User has the right password and permissions on the remote database server.

Make sure the ZM User has the right password and permissions on the remote database server.

I set up this additional storage in the ZM gui and it appears in the database:

Code: Select all

ZM_DB_HOST=mysql
# ZoneMinder database name
ZM_DB_NAME=zm
# ZoneMinder database user
ZM_DB_USER=zm
# ZoneMinder database password
ZM_DB_PASS=*************

And lastly, the zm mysql user has All Privileges with Grant on the zm DB.

It almost seems that somewhere in zoneminder the debian-sys-maint@localhost user is hard-coded. Even if I granted access in the remote DB, it would fail, as it's attempting to connect to localhost, instead of the 'mysql' server.

So I discovered a workaround.

I created a debian-sys-maint user on my remote database, with the password from my zoneminder system's /etc/mysql/debian.cnf.

This is still an issue, why would zoneminder be ignoring what's set in zm.conf?

Are there any config files in /etc/zm/conf.d that are overriding the zm.conf? If so the configurations in /etc/zm/conf.d/*.conf will override the zm.conf by design.

Something like "zmcustom.conf" or "any-name.conf" will be the culprit if this is the case.
