Appliance - MYSQL wont start

[jdoggy31]

Hello - I've been using the Zabbix appliance 4.0 for about 2 weeks now, and everything has been good. Today, when i try to login to the WEB ui, get Error connecting to Data Base: No such file or directory

when I try to Start MYSQL I get errors I have attached a snip.

I'm lost kinda lost, can someone help steer me in the right direction.

Please show us the output of

journalctl -xe

One of the reasons is that you ran out of disk space.

[jdoggy31]

dimir Thank You, I have attached the requested output. I tried to increase my disk space following the instructions on the manual. But it looks like the instructions don't match up perfectly and then don't work. I was finally able to extend the volume. using a few different forum threads.

But still no mysql start

Check mysql logs.

Looks like SELinux is blocking MySQL operations. See /var/log/audit/audit.log for details. Did you recently enable/modify SELinux?

[jdoggy31]

No SELinux changes Does the appliance even come with it .. Still struggling to find the answer. I have attached a snip of the mysql error log - Hopefull someone can help/

seems plugin error .,can you connect mysql ?

[jdoggy31]

I Cannot - I get a cannot connect to mysql through socket error

[solomonaom]

you can check mysql.cnf in socket path and check mysql.sock is exist

[jdoggy31]

I can find it in mysqld.cnf - Located in the exact same spot as a working version of the appliance. I attached a snip

[jdoggy31]

Ok navigating to where mysql.sock is supposed to results in an empty directory, Not sure how to get these files back

[solomonaom]

stop service mysql and bring mysql.sock back to default location in configuration and start mysql again
