Maria DB Randomly Crashes
I’ve installed full LAMP stack in my Droplet. I am not an expert but things seem to be working most of the time. But occasionally my SQL server shuts down.
When I try to run “mysql” command through bash window I got the error below. Most people say it is because of missing configuration in SQL ports. But when I restart the droplet everything returns back to normal, at least for a while until another random crash occurs.
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (111)
I’ve also checked SQL logs. There is a reoccuring pattern. The below error is logged everytime I have this problem. Can anybody give me some pointers about what it means?
