I had the problem   This process worked for me      Ensure that during remove process you choose No to deleting database    sudo apt-get remove --purge mysql   sudo apt-get autoremove  sudo apt-get autoclean  sudo apt-get install mysql-server mysql-client

I have the same problem and tried all the solutions posted here like    sudo apt-get autoremove mysql-server   but unfortunately it doesn t work for me on ubuntu 16 04  To uninstall the right package you need to     sudo apt-get remove mysql-   when you tried to autocomplete using tab the command it will list the following package    mysql-client           mysql-client-core-5 7  mysql-server           mysql-server-core-5 7  mysql-workbench        mythes-en-us            mysql-client-5 7       mysql-common           mysql-server-5 7       mysql-utilities        mysql-workbench-data      obviously choose the mysql-server-core-5 7 so it would be     sudo apt-get remove mysql-server-core-5 7   and now you can uninstall all mysql and reinstall again using these command from johnny s answer     sudo apt-get remove --purge mysql  sudo apt-get autoremove sudo apt-get autoclean sudo apt-get install mysql-server mysql-client   Now I solved it and the Error is GONE

This provides an alternative solution if the issue relates to you  If your disk drive is full than the MYSQL server  and most other programmes  is unable to start  Delete files and folders to allow Mysql-server to start up

In my case the problem was that I had added  default-character-set utf8  to my cnf and that was corrupting the file  Instead change that line for  character set server utf8   That should solve it  hope this helps

If you look close  you ll see the difference    The server listens on  var run mysqld mysqld sock The client tries to connect to  var run mysqld mysql sock   You ll have to adjust the one or the other

There is another chance of you to get this particular error if you modify the max connections in my cnf file   I also faced the same error which did not let me log in to MySQL server  In my case the problem was  I had to increase the max connections size in       etc mysql my cnf   to  set-variable   max connections   5000   Due to this reason next day when I stared MySQL server it threw this error  ERROR 2002  HY000   Can t connect to local MySQL server through socket   var run mysqld mysqld sock   2    Removing the set-variable   max connections   5000 segment from my conf file did the trick  After removing that particular segment following command was used  MySQL server started up and running like previously   sudo  etc init d mysql start

My problem was solved checking if the process was running on Ubuntu 12 04  ps ax   grep mysql   Then the answer was that it wasn t running  so I did  sudo service mysql start   Or try  sudo  etc init d mysql start

Two main reasons   1  mysql-server isn t installed  You have to install it  mysql-server and not mysql-client  and run it   2  It s installed by default and running  So  it s not possible to run it again through Xampp or Lampp  You have to stop it  sudo service mysql stop  then you can start it through Xampp  It s possible to check if it s running or not with this code  sudo netstat -tap   grep mysql  If you see a result like this  tcp    0      0 localhost mysql                LISTEN      1043 mysqld  It means that it s running properly

This is an old tread with different solution proposed  but none of them worked for me  I m adding this answer in the hope it will help somebody who struggled as me for some time    I ve checked all the existing answers and all the existing solution  but for me the issue was incorrect user permission on var run mysql folder   I ve checked the user permission on that folder and it was set to root  Once i changed to mysql mysql the problem has gone   So enter into  var run mysqld and change the user permission to   chown -R mysql mysql

I was stuck with this error too  and it took almost 3 hours to find it    First of all  try to recall the changes that you made to your conf file  then undo the changes and save the file and start mysql  If you want to make any changes to the conf file  then stop mysql server and then change the desired values and restart mysql    This error occurs because of an incorrect  wrong keyword or wrong value assigned  change made to the conf file  Most of the times this error occurs even if you restart the machine running the server  as the server is stopped  in that case  start mysql server

Once you install or update MySQL  it won t ask you to create the root password  In that case  you will have file called  debian cnf  path   etc mysql  You will find user name and password  login with that credentials and create new user and password
