My site is on Wordpress and is hosted on a VPS server. The traffic is not much but the database connect error is displayed many times, and then I had to restart MySQL.
I've checked the MySQL error file log. Here is a certain portion of the log.

I do not understand anything about this. Could anyone explain the issue to me or suggest a fix?

Thanks

Your MySQL seems to have not enough RAM.
Let's say you got a guy (mysql) who carries a package of stones(data in mysql) from point a to point b over a bridge.
By the times you add more stones(more data) to the package.
And maybe there are also more guys (more mysql instances, because more visitors on your website) on the street.
Then imagine a bridge where all this guys have to pass, which has a weight limit (RAM).
So only a few guys can walk over the bridge and others are told to either wait or (if there are too many guys waiting) go to hell with their packages.
You may either delete some data or you may limit the amounts of users or you can try to optimize the packages.
Do you really need to carry all the data or is there a way to produce the data faster?
For the second option read about mysql indexes.
I'm running Ubuntu 14.04 and I've got a few WordPress installations on my server.
Without warning, MySQL crashes every day on my server and I've yet to find the reason.
You can find the error.log below.

Case 1: You have a tiny 1G server (or VM). If so, lower innodb_buffer_pool_size to, say, 32M.
Case 2: You have increased various other mysql settings to unreasonably high values. Undo.
Case 3: You have lots of applications in your small server; they are consuming most of RAM. Find and fix.
If you need further assistance, tell us how much RAM you have, what else is running and provide my.cnf.
Or you could get more RAM.
I noticed in WHM that MySQL 5.5 has an EOL December of 15' and I upgraded to 5.6 and now MySQL crashes at least twice a day, but it restarts after failing.
Here is a sampling of the error log.
Any idea what is going on?
Thank you.

MySQL 5.6 is not supposed to use 5.5 unmodified data files - the format changes in every version and, sometimes, it changes even for patch versions.
After an upgrade you should run mysql_upgrade. Then, you can use your database normally.
First item of action would be to disconnect from your website immediately to prevent further corruption. One way to do this is to just alter the credentials of your application.
You'll need to perform a repair of the data to fix the inconsistencies in the binary logs.
Please refer to this article from MySql, which provides steps to repair. The tool mysqlcheck should be available in the command line.
My Innodb Engine is getting crashed frequently.
I could not find the reason behind this.
This is the error log:

Can anybody help me to stop this unwanted Innodb crash.
Thanks in Advance...
The log indicates that MySQL was not shut down properly, but that it recovered just fine (at 9:22:52). It was later shut down properly (at 13:00:37 and 13:19:51). What makes you think that it is crashing?
There was a crash, and then there was a normal shutdown.
Probably it allocates too much memory. Probably SELinux, or App Armor, shutdown MySQL.
I am having some problems with MySQL - the service has stopped and will not restart.
I have an XAMPP stack running MediaWiki which is what uses the MySQL database. The server itself is a VM running Windows 2003 SP2 with 512MB RAM.

Fixes Attempted:
Tried starting from services - error 1067 - "The Process Terminated unexpectedly"
Tried restarting the server itself - no good
Tried moving the ib_logfile0 and ib_logfile1 files from directory and restarting server no good
Tried killing the PID of MySQL from command prompt in case it was still running but it was not running.
If anybody could point me in the right direction it would be much appreciated.
NB> I am also trying to get the RAM of the server increased in case that is the issue. At the moment of the 512MB only about 90MB is free.
thanks
