When I open XAMPP and click start MySQL button and it gives me an error. I had started it just before, but now it isn't working.
It given error below in xammp
Error: MySQL shutdown unexpectedly.
This may be due to a blocked port, missing dependencies,
improper privileges, a crash, or a shutdown by another method.

What is the cause of these errors and how can I rectify them?
For my, open and empty the file multi-master.info which is at the base of folder data is enough for me.
There are several causes to this problem, and here are some solutions:
Change Your MySQL Port
One of the main causes of this error “MySQL shutdown unexpectedly” is another software using the port assigned to MySQL which is 3306. To verify this you can use netstat module from XAMPP’s control panel, right above the Shell tool. You can fix this problem and prevent it from repeating in the future by simply changing mysql port. To change it, do the following:
Click Confing found at the top right corner
Click Services and Port Settings
Select MySQL then change 3306 to 3307 then click save
On the main xammp screen, Click on mysql's config then select my.ini then search and replace 3306 with the new port number used, in our case 3307 then save
Restart xampp then the problem is solved! But if your problem is not solved, proceed to solution number 2 below
Restore Your Database Backup
Onother reason for this error is corrupted database, to fix it simply restore your database backup which is created automatically by xampp. By default, your XAMPP MySQL backup files should be under Local Disk > XAMPP > MySQL. Inside that directory, you’ll see several folders, two of which are called data and backup. he data folder includes all of the files that your database uses. The backup folder contains a single recent copy of your MySQL. To restore the MySQL backup, change the name of the data folder to anything else, such as data-old. Then rename the backup folder to data. That’s it!
Fix this error with just 2 steps:
Task Manager
Find MySQL -> end task
Go back to XAMPP -> star MySQL, port 3306 should work again.
If you do this it is possible that some DB that you are also using in that port will be deleted, make sure you have a copy before proceeding.
Open data folder and delete all ib_logfile* (ib_logfile0, ib_logfile1).
Then restart xamp, so it solved for me.

what may cause the problem and how can I resolve them? Thank you in advance
I Got it worked. Didn't change the port and kept it default as 3306. Did the following.
renamed the XAMMP\mysql\data folder to any other name you wish (say data_old )
make a new folder in XAMMP\mysql name data and copy all the files in it including ibdata1
close all running programs and restart XAMPP
No need to copy files from data_old but if you do have previously constructed databases then you may copy some files from data_old.
Special Thanks for everyone who supported.
The easiest way is change port to 3307 or other than 3306 from my.ini and edit "\xamppphp\MyAdmin\config.inc.php"add extra line under
$cfg['Servers'][$i]['AllowNoPassword'] = true;
$cfg['Servers'][$i]['port'] = 3308;
if u need explaination I've made Youtube video sE2UkEcth0w
https://www.youtube.com/watch?v=sE2UkEcth0w
seems like following error from the message
Either port is blocked
Or Application doesn't have enough permission to access those port and serve web application.
To fix this
Right click on XAMPP and Click on Run as Administrator
This will prompt you for password or confirmation.
Allow by providing password or permission
This will run XAMPP in highest privilege, so you won't be facing permission issue anymore.
If this works, you can do few more step to avoid running as administrator manually every time.
Right click on XAMPP icon
Go to properties
Look for option > Run as administrator
[*] check the option and save
This will ask for confirmation/password every time when you run XAMPP.
Hope this solves your issue.

Tried to:
Rename the folder mysql/data to mysql/data_old (you can use any name)
Create a new folder mysql/data
Copy the content that resides in mysql/backup to the new mysql/data folder
Copy all your database folders that are in mysql/data_old to mysql/data (skipping the mysql, performance_schema, and phpmyadmin folders from data_old)
Finally copy the ibdata1 file from mysql/data_old and replace it inside mysql/data folder
Start MySQL from XAMPP control panel
Also tried:
exit Xampp server
go to your C:\xampp\mysql\data directory
delete the ibdata1 file
restart xampp server
Who knows the solution?
If anyone will be interested in the answer, just reinstalled the xammp control panel since it was still giving me errors
btw for future reference this can happen when you shut down your computer with xampp still running.

how do fix this error?
I fixed using this article:
Rename the “data” folder
Rename the “data” folder to “data-oldfiles”.
This is very important to rename the data directory to any new directory name.
Create a new “data” folder
Create a new folder and give the folder name as “data“
To solve the problem we need to create a new “data” directory in the mysql database.
Copy content from “backup” folder
Go to the “backup” folder and copy all files.
Paste the files from backup folder to data folder
Now start the MySQL database from XAMPP.
Now, your MySQL database will start properly without showing any error.
Transfer all MySQL projects Database, Data file & Log files
If you have many database which was used for various projects, then you have to transfer all database from “data-oldfiles” folder to “data” folder.
Copy all databases from the data-old files and paste to the data folder.
Now you have to copy the data file “ibdata1” & all log files “ib_logfile0, ib_logfile1 ” from data-old files folder to the data folder. If you have many id_logiles then copied all of them.
you can end task mysqld.exe or mysqld on task manager. Then run again MySql. It will work. (On Off Engineering).

finally, I moved xampp/mysql/backup files into xampp/mysql/data and run mysql again.Then, it worked!But I don't know why.What led to this problem.
Hope someone doubts for me！
I searched on google and tried everything like port changing, delete files, reinstall xampp, copy and paste backup files to mysql/data folder but nothing worked.
I found the best solution to this problem.
Solution:
go to xampp/mysql/data and take a backup of this folder
delete all selected files in the below image
Copy selected files in below image from xampp/mysql/backup and paste it to xampp/mysql/data folder
Now restart your xampp server and it will run like before. no need to delete your database or reinstall your xampp server
If you're not running XAMPP as an administrator, shutting down MySQL can cause corruption which means you have to repair or delete your tables. This can easily be avoided by running XAMPP as administrator.
Open Services on XAMPP Control Panel
Look for the service MySQL80, right click on this service and click Stop
Get back to XAMPP Control Panel and start MySQL
this worked for me.
Open Services on XAMPP Control Panel

in the last few days my log files have recorded hundreds of those errors, the website is working fine and I am not able to replicate this issue. I believe the error occur when there is a lot of traffic on the website (actually in my access logs it looks like the more errors are caused when crawlers are scanning the website).
I've seen a similar error when exporting the database (few hundred of MBs) through Sequel Pro where in some case "the mysql server has gone away" but if I wait few seconds and try to reconnect the export continues.
I was wondering if there is any fix or if there is any log I can check to find out more about this error, I know that probably increasing the server resources could make the error disappear but I want to be sure that's the real cause.
Is there any mysql config I should look at that could cause (or mitigate) that error?
I also have another question, I'm connecting to mysql using localhost as host, do I get any benefit if I change it to 127.0.0.1?
PS: the backend is a Laravel php application, the more errors have been registered in the homepage (there is only one query being executed on that page and it's a simple select * from table, the table has < 1000 records and it's well indexed, two queries if you are logged in).
The website doesn't have so much traffic, around 6k pageviews per day - excluding crawlers.
In some case the first error I get is a "connection refused" followed by the "no such file or directory"
2016-11-15 09:01:07 PDOException: SQLSTATE[HY000] [2002] Connection refused
2016-11-15 09:01:07 PDOException: SQLSTATE[HY000] [2002] No such file or directory
This is what the mysql error.log looks like when I get the mentioned error (in both cases, when I first get the "connection refused" and when I just get the "no such file or directory":

The diference between using '127.0.0.1' and 'localhost' is that mysql will try to connect using standard network mechanism or using a local machine socket (this one is recommended because its faster)
The error appears because Doctrine has some kind of "localhost socket detector" that appears to fail in several cases, as described in here
PDOException SQLSTATE[HY000] [2002] No such file or directory
or
Troubleshooting "No such file or directory" when running `php app/console doctrine:schema:create`
The best solution (using 127.0.0.1 it doesnt look the good one for me) is to discover the socket location
mysql> show variables like 'socket';
+---------------+-----------------------------+
| Variable_name | Value |
+---------------+-----------------------------+
| socket | /var/run/mysqld/mysqld.sock |
+---------------+-----------------------------+
and pass that value to the mysql connector on php (in laravel it seems that its located in database.php)
