Question

Ubuntu 12.04 MySQL permissions

  • Posted June 3, 2014

I have a strange problem. Every now and the access to the mysql database is forbidden. I can’t login even as root. If I reboot ubuntu server everything is back to normal. Sometimes just couple of hours, sometimes almost for two weeks. Anyone knows what is the issue here?

Is there anything in <code>/var/log/syslog</code>?

Database error. Nothing in mysql.err

Sorry guys I have to wait for error to happen :)

Is there anything in <code>/var/log/mysql.err</code> What’s the exact error you get when you are denied access? <br>

Nothing…

I’m guessing MySQL is running out of memory and crashing. What’s the output of the following command? <br><pre>grep -i “oom” /var/log/syslog <br>grep -i “oom” /var/log/dmesg</pre>
