It was working fine for month. But today i wanna start working and cant connect to MySQL anymore.
Im using XAMPP 1.7.7 on Windows 7
XAMPP Control Panel says MySQL is "Running" and shows "Mysql started [Port 3306]"
But when i go to localhost and click status, it shows "MySQL database Deactivated"
When i go to phpmyadmin it shows: "2002 - The server is not responding (or the local MySQL server's socket is not correctly configured)"
Also mysql_error.log file at C:\xampp\mysql\data shows no errors?

Any ideas? :(
The question is old, but I have just had the same issue so I will write my solution.
It could be a problem with Xampp.
Try to uninstall and install again.
But before, you can try also something that worked for me, namely run the file:
C:\xampp\mysql\resetroot.bat

When attempting to start the mysql server, it returns with exit code 1. I've done this a million times before on this server. Without messing with the server in the past month, mysql has suddenly stopped and I can not start it. My error.log:

Until I can start mysql-server, I can not run mysqldump nor mysql -u root:
Got error: 2002: "Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2 "No such file or directory")" when trying to connect
I'm running mariadb-server 10.1.23-9-deb9u1.
Not sure if this will work but since the server doesn't work anyway so try this out:
Rename logfile0 and logfile1 and then restart the server.
Before doing anything, make a copy of the entire mysql folder to another location just in case.
The answer was right infront of me:
InnoDB: Set innodb_force_recovery to ignore this error.
I set innodb_force_recovery = 1 after the [mysqld] clause in my /etc/mysql/mariadb.conf.d/50-server.cnf (This file may very depending on your OS).
I restarted it and it repaired itself. I later took out the innodb_force_recovery = 1 and restarted again, it then worked just fine.
What did I learn? Have more faith in "auto-repair" procedures. My expectations were so low for them because of my exposure to Microsoft Windows.
I am experiencing regular MySQL server crashes (on Linux). After running
sudo /etc/init.d/mysql restart
the problem goes away, but temporary. It might be one day or couple, but the crash will happen anyway. Here's an excerpt from the error log file, after the crash and before the daemon restart. I am not sure it reflects any useful information though.

The problem did not disappear after reinstalling the server.
Perhaps it's time to install the database on clean OS install, and bring all my databases there, but before such time-consuming solution I'd like to try some less-involving ones, if there are any.
I am trying to install multiple instances of MySQL on a Windows Server 2003 using this link.
First instance which is on port 6699 get configured and working successfully. But when I try to install another instance on default port (3306) MySQL service gets hung on "Starting" status. This is the log

Double check your configuration!
Make a binay backup or entire /var/lib/mysql.
If you don't need most recent data, delete the log files and try to start.
If you need your data, try the followling:
Try innodb_force_recovery = 1 to 6 all six options in an increasing order.
Assume the worst -- innodb disk image corrupted.
If you are lucky you can salvage most of your data, perhaps mysql starts in one of recovery modes, run checksum on each table, see what tables are still ok.
If mysql refuses to start up to certain recovery mode N and crashes on startup with recovery mode N, then go looking for those daily/weekly backups I hope you system was configured to take.
In my Moodle database, everytime I select the mdl_certificate table, the MySQL server goes down. I thought it could be a problem with the PHPMyAdmin, but I installed the MySQL Workbench and the same still happens.
So I tried the console. The problem persists. I got two prints:
I've never seen this. How can I solve it?
Thanks!

The solution was drop the tables and re-create them. Luckly, they were empty.
I have searched high and low for a solution to this problem. My MySql gives me the following readout:

Everytime it starts. I've tried deleting files, dropping the database, running Magento's Repair Database Tool, starting all over with a new database but no matter what I get this error.
It makes me uncomfortable because I'm not sure something might get corrupted or IS corrupted. I'm using Windows Vista, and Xampp but I also was using nginX with the same thing showing.
I just recreated a brand new database and now after shutdown (which I have to do sometimes) the error is showing up again! Is this a normal thing or is there somehing wrong?
Thanks
As you can see from the log InnoDB starts crash recovery:
InnoDB: Starting crash recovery.
The reason for that is MySQL shut down wasn't clean. Why? May be MySQL has been exiting too long and OS kills the process (if you reboot the server). Or MySQL crashes due to a bug.
