Question

even though

Answer 1

On Debian this was a bind problem for me so changing bind-address from localhost to 0.0.0.0 helped.

vim /etc/mysql/my.cnf 

bind-address = 0.0.0.0

Answer 2

I deleted everything connected to mysql with

sudo apt-get remove --purge --auto-remove mysql-client-5.7 mysql-client-core-5.7 mysql-common mysql-server-5.7

sudo rm -r /etc/mysql* /var/lib/mysql* /var/log/mysql*

and then reinstalled it again with

sudo apt-get update

sudo apt-get install mysql-server

and then started it with

mysql -u root -p

followed by the password

Answer 3

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.

I have follow Wellington Lorindo posting. And My problem was solved.

Steps 1. run in terminal

ps ax | grep mysql

Result was

11514 pts/0 S+ 0:00 grep mysql

Steps 2. Again type this

sudo service mysql start

And problem solved.

Thanks Wellington Lorindo

Answer 5

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.

Answer 6

I had the same problem when i installed xampp on my system. The mysql server looks for /var/run/mysqld/mysqld.sock but the mysql.sock file was in xampp folder so i used

 find / -name '*.sock'

to find the mysql.sock file and then used

ln -s <the file location> /var/run/mysqld/mysqld.sock

to get a link for the *.sock file then tried mysql and it ran without error. Hope this could solve yours.

Remember to create the directory if it does not exists.
