ZoneMinder Forums

Hello, I've followed the guide to install Zoneminder on Ubuntu 16.04 (Easy way), which all went well. After that, I was encouraged to enable OPT_AUTH, which I could not find. I did find OPT_USE_AUTH, which is now enabled (I assume that's the same). I can successfully login http://server/zm, configure camera's en view them. I have tried the zmview app on the smartphone, works. But znNinja does not, it claims that it cannot find a valid API.
So I started to troubleshoot API, it already goes wrong at http://server/zm/api/host/getVersion.json, which gives me HTTP Error 500. Even when I login first and then open this page, it is giving me the same error. The /api/Config/database.php file is in place and all is running on the same server.

I expect it has something to do with PHP dependencies not being met, but I don't know which one. Right now I am running PHP version 7.2 on Ubuntu 16.04 LTS. I hope someone can help me out

Drop back to PHP 7.0. The zoneminder install for Xenial does not support PHP 7.2.
If you are brave I can give you a patch that may work. We had to come up with a fix for Bionic, which uses PHP 7.2, so the fix may work for Xenial.

Hi bbunge, are you referring to the 'Zoneminder API fix'? I did read about that, haven't found it though. What does it do, does it change things to the overall PHP7.2 settings? Or just the Zoneminder (API?) settings? I think I'm brave enough

If it helps, I could share the contents of /tmp/zmlogs/cake_error.log

You should be able to use this script to "rescue" your install. Since Ubuntu 18.04 uses PHP 7.2 the procedure should work. You can also upgrade to ZM 1.32.1.

That worked great! I just did the lines step by step, I already knew I had most of it in place. Right after this, /getVerion.json shows me

{"version":"1.30.4","apiversion":"1.0"}

and now zmNinja works as well

Thanks so much! Btw, are there any benefits omg upgrading to 1.32.1 on Xenial? I am planning migrating to a new Bionic install in a couple of months, since I have been dist-upgrading since 12.04 and I guess starting fresh would benefit me more.

1 small issue I found with zmNinja, it seems to loose the connection when I reopen te app. Lost show 401 Not authenticated, when I reconfigure the authentication it works again. So it seems like the auth. token is not being refreshed correctly?

[edit]

This issue seems to have been resolved by itself, perhaps a reboot was key?
