The guide contains another error that's probably preventing the database from starting...

innodb_log_file_size - 32M should be innodb_log_file_size = 32M (equals instead of minus)

You have hawk eyes, good find !!! I will try it now
ALSO an extra space
innodb_buffer_pool_ size = 256M
innodb_buffer_pool_ size = 256M

Mariadb is running but instituted a new error connecting to zm Apache is running fine

Trying to find a log, is it apache or zm to give me a hint


Miscellaneous:

Like I said previously it only a P5Q motherboard with a Q6600 processor been running Master for ever with 4g ram but just added 4 more gig. Due to playback java error stated by iconner, it was beyond my skills to track it down so I just wiped the server and start fresh...its been a while.

Asker said the install bash script was updated about 2 months ago, so I had used an older one I guess

404 Not Found is an Apache message. It sounds like the ZM configuration file (which defines the /zm* aliases) isn't being loaded. It's typically, well on CentOS anyway, a symlink pointing from /etc/httpd/conf.d/zoneminder.conf to /etc/zm/www/zoneminder.conf

I caught the extra space as well: viewtopic.php?f=44&t=31329#p124470

Any problems when you changed the size of the InnoDB logfile?

I've updated the wiki

kitkat wrote: ↑Mon Nov 29, 2021 4:10 pm Any problems when you changed the size of the InnoDB logfile?

I tried 1/2 the values no go
innodb_buffer_pool_size and innodb_log_file_size have default values if not set acorfing to mariadb so I entered those values and it still tanked. wish I wrote them down.
If I comment out the innodb all boots and runs fine in zm from what I see

Its bugging me, I don't want it to reflect on zm if someone new has the same problem
------------------------------------------------------------------------------
I just logged in to my HP dv6 upstairs
innnodb's enabled error on zm install
Job for zoneminder.service failed because the control process exited with error code.
See "systemctl status zoneminder.service" and "journalctl -xe" for details.

innob's comented out
zm installed and running

------------------------------------------------------------------------------
Yes innodb' below "[mysqld]"

Check the DB logs and get to the bottom of the problem.

I think that the failure to start is very probably related to changing the size of the InnoDB log files (barring any other typos and errors in the guide of course!), but this is coming from my CentOS-centric perspective and it may be that mariadb/MySQL doesn't behave this way on other distros.

The mariadb log (/var/log/mariadb/mariadb.log on CentOS) should show what's going on - This will display the last ten errors in that file: If the output contains something like this then the log files are very likely to be the problem: (The lack of such output doesn't rule out the log files being a problem because there may be later errors hiding them and you should inspect the logs in more detail.)

If you do see those errors then you can try this to see if they self-repaired: A good result would look something like this: (The leading digits are a YYMMDD datestamp so you can tell whether they're recent or not.)

So, if you see errors but not 'to be created' messages then the log files may well be the problem, and you should be able to fix it like this:
Hopefully you'll see a "InnoDB: Log file ./ib_logfileX did not exist: new to be created" message or two, but if it still doesn't start then you'll have to inspect the logs for other problems.

A very minor thought is the spaces around the ' = ' in my.cnf. I'm sure they're probably fine but I've never seen them used and I always avoid whitespace where possible. My my.cnf contains these innodb_* directives under [mysqld] (If you use other values, log_file_size should generally be one-eighth of buffer_pool_size.)

Good luck!

OK...

grep is saying "/var/log/mariadb/mariadb.log: No such file or directory" so your log file isn't at /var/log/mariadb/mariadb.log.

Hmm.. Or perhaps it is there but you need sudo to access it? (I always forget that bit because I'm usually root. Yeah, I know...) To avoid that sort of problem you could probably sudo su and get root privileges for the whole session.

Basically, try the grep stuff again but prefixed with sudo (and a space!) or make sure you have root privileges some other way and see what it says. If it still says it can't find the file then you'll have to locate it and substitute the correct path in the commands.

Some of the things I posted and which you tried were examples of output rather than actual commands

This looks to be a problem though:
There may of course be other flog_file_size related errors to come but it's not even getting that far. Maybe paste your entire my.cnf here so we can see what it looks like, with the edits and without.

I was logged in as root

I also did a filesystem search for mariadb.log, nothing

Well I think I had enough beating a dead horse on this.
I spent days researching Innodb beyond my skills to reason why the settings are there

I have a xampp install for Point of sale testing, same mariadb version on win 10

I used the Innodb settings from xampp in linux and it worked
I also increased the file_per_table and the Log_file_size in linux to 256M and 32M respectively and that worked also, with the additional variables

Crazy as this test was, It didn't matter to me since I would reformat the pc and start over, install expendable.

Im just going to leave innodb settings out and let mariadb use its default variables.

Thanks guys, hope I didn't waste to much of your time

Jimmy

Your logs show it is using the default of 128MB I'm not sure why you'd want to change it.
