MySQL going down and service monitor not working
« on: January 14, 2016, 04:35:35 AM »
Hello,

I have this problem since last few days. MySQL goes down on random times. At first i just visit centos web panel page and it restarted MySQL automatically. Then i set cronjob via service monitor with 10 minutes time but after few hours MySQL gone down again but cronjob didn't fix it. Then i set the same cronjob directly in the system.

*/10 * * * * /usr/local/bin/svcMonitor

My named service was down and i start getting this email after every 10 minutes, which means cronjob is working fine.
"rndc: connect failed: 127.0.0.1#953: connection refused"

I fixed the named service and emails stopped but MySQL gone down again today and cronjob didn't restart it automatically and i didn't get email either. My sites were down for 3 hours. As soon as i came back online. I just visit centos web panel page with 2030 port and it fixed MySQL. Now i put a new cronjob to visit this page after every 10 minutes. So it can restart mysql if it's down.

*/10 * * * * wget -O - http://www.example.com:2030 >/dev/null 2>&1

Can someone please help me why svcMonitor is not working for MySQL and if this URL visit method will help?

you would need to know the real reason why your server goes down, restart of mysql isn't good if you have continuous issues.
MySQL restart is good if this happens once in few months and you are not monitoring your servers.

It would be the best that you check this with your system admin or our managed support since mysql crash is a serious issue and could cause data lost or database corruption.

In some cases mysql is related with the disk space usage so you should check mysql logs and if you have any disk space free.
