Clean installation on Ubuntu 18.04 - Cameras not working

[Jerubei]

Hello, guys,

I've just installed 18.04 and Zoneminder 1.32 using the first script on this page:

https://wiki.zoneminder.com/Ubuntu_Serv ... e_easy_way

As far as I can tell, everything went smoothly. Then I used the camera configurations from my old ZM install, but all three cameras (two models in total) are not working. The logs show the following after I try to view one of the cameras:

I'm using Firefox, so cambozola shouldn't be needed, nph-zms is set at the same path as my old zoneminder install... The only thing I can think of is that I've not setup CGI in apache, since this is a new install, which I'm not sure how to do - any links or help is much appreciated!

Did you start with a fresh Ubuntu install?
Did you reuse the database from the old ZM setup?
The Zoneminder package enables cgi in Apache2 and the script reliably sets up Zoneminder to work. Look to something you missed in the cam config.

Thank you for your reply!

Clean install of Ubuntu 18.04 - the only specific thing is it's on RAID1, which shouldn't matter.

Clean install of ZoneMinder using the script, which I've linked.

I've not reused anything from the old installation, except manually entering the camera configurations. Cameras work in VLC, but not in ZM.

As you can see from the logs, I get two errors - about shm not allocating memory and cgi not working.

What should I check?

[bbunge]

Check your timezone. The script uses info in /etc/timezone to append a line to /etc/php/7.2/apache2/php.ini. In 1.32.x if the PHP timezone setting is not right you can have issues.

Camera resolution in Zoneminder does not match camera output. Use VLC (Tools, Media Information, Codec) to check camera Display Resolution. Do not assume the camera specification resolution will work!

When I install Ubuntu I use the mini.iso and a network installer with a very minimum OS. No desktop. No basic server. You will have to use Legacy boot but you will have an operating system that runs without other apps using resources.

I would encourage you to use the development version in the zoneminder-master PPA. Much work has been done on it and it runs smoother than 1.32.x. Easy enough to modify the install script and you do not need to modify php.ini for timezone as this setting is now in ZM options.

[Jerubei]

Purged 1.32, including the database, reinstalled from Master PPA, seems to be working now.

One more question - does ZM still need fstab entries for saving to a mounted drive or can this be achieved otherwise with 1.33?

Thank you for all the help!
