Any help will be appreciated thanks.
How comes this happen? did change anything like prefix of wordpress, changes made to mysql or php version or any changes to server? may be those are the issues. Please provide the related information. Its due to corrupted database.
find wp-db.php and add this line $this->query("set session wait_timeout=300"); after $this->ready = true;
goto wp-config.php and add define('WP_ALLOW_REPAIR', true);
goto https://yourwebsite.com/wp-admin/maint/repair.php and click repair your database
or simply upload old backup

I have been trying mysql_upgrade, mysqld --initialize-insecure it doesn't help me.
My script feature is it running 16 threads 24 hours per day without stopping. So 16 connections are connected to DB everytime.
On mysql configuration I have set:
interactive_timeout=31536000
wait_timeout=2147483
And nothing more unusual.
I have this situation second time, when the DB was broken.
I want to know, why do I get this problem and how to solve it.
Sorry for my English. I have some problem in starting mysql service on Xampp control panel. I follow the steps from this site https://gist.github.com/odan/c799417460470c3776ffa8adce57eece because I want use mysql as type server on phpmyadmin and not mariadb as a default.
I followed those steps once and it worked but because of some reasons I had to unistall Xampp and mysql server, and now I can't start it. I've already read some questions but none of them helped me at all.
The error that appear at console is:
20:12:28 [mysql] Error: MySQL shutdown unexpectedly.
20:12:28 [mysql] This may be due to a blocked port, missing dependencies,
20:12:28 [mysql] improper privileges, a crash, or a shutdown by another method.

I will be very grateful if someone can help me.
I have been using Xampp to test my website stuff and everything was working perfectly until I decided to install Microsoft SQL SERVER 2017 to do some data science stuff (school stuff).
Now I can still start Apache but I cant start MySQL. Here is the log :

2017-11-17 13:40:06 13304 [ERROR] Aborting
I tried shutting down the SQL Server using SQL Server Management but I still can't connect MySQL.
You can change port of sql server or mysql server and dont forget to specify the port while accessing it.
Since Microsoft SQL Server and MySQL/MariaDB/Percona use different ports (and it doesn't sound like you've changed from the defaults), I doubt this is related to you installing SQL Server. SQL Server uses port 1433 and MySQL port 3306.
As for what is using that port, https://stackoverflow.com/a/48199/2385479 helps us. There is a suggestion for the TCPView Sysinternals application or the alternate suggestion of using netstat (such as C:\> netstat -a -b -n) which should give you some idea of what's using port 3306.
It seems to me you probably have another MySQL server installed which is conflicting with the port XAMPP is trying to use.
As in the log, when you installed the SQL Server it "reserverd" the same port that your MySQL was using
2017-11-17 13:40:06 13304 [ERROR] Do you already have another mysqld server running on port: 3306 ?
You can change the MySql port in the my.ini file, which can be acessed by the Xampp Control Panel, under "config".
Or, you can change de SQL Server Port, following this tutorial: https://www.syskit.com/blog/change-sql-server-port/
I open the XAMPP (7.0.23) Control Panel (v.3.2.2) and start Apache and MySql. Apache connects immediately, but MySql takes a long time to display the port (3306) on the panel and start the connection. I already changed the MySql port for others but it did not work. I've also reinstalled XAMPP twice without success.
Using Win 10.

The log seems ok for me. Maybe you have permission problem, try (right click) run as Administrator the Xampp
try check your active port, maybe used by another program. Mysql use 3306 as default port. go to your xampp folder try find "portcheck.exe" or something like that. see if your mysql port used or free.
