I had this issue on arch linux as well. The issue was pacman installed the package in a different location than MySQL was expecting. I was able to fix the issue with this:

sudo mysql_install_db --user=mysql --basedir=/usr/ --ldata=/var/lib/mysql/

Hope this helps someone!

mysql_install_db

Answer 3

I got similar error on overlayfs (overlay2) that is the default on Docker for Mac. The error happens when starting mysql on the image, after creating a image with mysql.

Switching to "aufs" solved the issue. (On Docker for Mac, the "daemon.json" can be edited by choosing "Preferences..." menu, and selecting "Daemon" tab, and selecting "Advanced" tab.)

/etc/docker/daemon.json :

{
  "storage-driver" : "aufs",
  "debug" : true,
  "experimental" : true
}

Answer 4

initialize mysql before start on windows.

mysqld --initialize

Answer 5

1. Uninstall mysql using yum remove mysql*

2. Recursively delete /usr/bin/mysql and /var/lib/mysql

3. Delete the file /etc/my.cnf.rmp

4. Use ps -e to check the processes to make sure mysql isn't still running.

5. Reboot server with reboot

6. Run yum install mysql-server. This also seems to install the mysql client as a dependency.

7. Give mysql ownership and group priveleges with:

   chown -R mysql /var/lib/mysql

   chgrp -R mysql /var/lib/mysql

8. Use service mysqld start to start MySQL Daemon.

Answer 6

If you move your datadir, you not only need to give the new datadir permissions, but you need to ensure all parent directories have permission.

I moved my datadir to a hard drive, mounted in Ubuntu as:

/media/*user*/Data/

and my datadir was Databases.

I had to set permissions to 771 to each of the media, user and Data directories:

sudo chmod 771 *DIR*

If this does not work, another way you can get mysql to work is to change user in /etc/mysql/my.cnf to root; though there are no doubt some issues with doing that from a security perspective.
