Setup: Error connecting to database

[Thomas Stoiber]

I have followed the tutorial https://linoxide.com/tools/install-jira-on-ubuntu-linux/ but at the stap 4 I cannot connect to my Database (Error null - see Picture below).

The Database jira_db, as well as the user jira_user exists in the Database.

Where can the error lie? And what is the Error (null)?

I suggest you to check atlassian-jira.log file in {jira_home}/log folder. You can post it here and I can check it.

That's not the directory Martin asked for.  Please look at the single file Martin asked for, not a random collection of files from a different directory.

Where do I find jira_home then? I thought it is /opt/attlassian/jira
I didn't find the exactly file, so I posted the folder

Thank you @Nic Brough -Adaptavist- , @Thomas Stoiber it should be placed in JIRA HOME directory and its log sub-directory (https://confluence.atlassian.com/adminjiraserver/logging-and-profiling-938847671.html#:~:text=Administrators%20global%20permission.-,Log%20file%20location,of%20the%20system%20information%20page.) but it depends on configuration sometimes

I couldn't paste the content in here, so you can find it here:

The log I saw there is from a Jira that has gone way past the installation .  So I am a bit list on where the problem is.

Maybe some compatibility issues? In supported platforms document for your version (https://confluence.atlassian.com/adminjiraserver078/supported-platforms-947188411.html), there is a note for MySQL to use this driver - https://dev.mysql.com/downloads/connector/j/5.1.html.

BTW, why are you installing old version of Jira (7.8.2)? I suggest you to install at least 8.10.
