I got this problem too, but I just did:

sudo service mysql restart 

It worked for me.

Answer 2

Make sure you have backups of important databases and then try uninstall MySQL related stuff:

apt-get remove --purge mysql\*

Then install it again:

apt-get install mysql-server mysql-client

This worked for me and data was kept.

If PHP MySQL shows errors you might have to reinstall PHP MySQL:

apt-get install php5-fpm php5-mysql

Answer 3

I also facing same problem it will be occur if your mysql server is not running by default it will again stop after some sec so you again run ($ sudo service mysql start ) command you can change if know.

for that use command

$ sudo service mysql start   

(put user password if required because we use sudo ) and then run

$ sudo mysql -u root -p          (put user password if required )

now you got your database

I solved this by killing the mysql process:

ps -ef | grep mysql
kill [the id]

And then I started the server again with:

sudo /etc/init.d/mysql restart

But start works as well:

sudo /etc/init.d/mysql start

Then I logged in as admin, and I was done.

Answer 5

In my case it worked by doing some R&D:

I am able to connect to MySQL using

root-debian#mysql -h 127.0.0.1 -u root -p

But it's not working with mysql -u root -p.

I did not find any bind-address in my.cnf. So I outcommented the parameter socket=/var/lib/mysql/mysqld.sock in my.cnf which was causing me a problem with login.

After restarting the service it went fine:

root@debian:~# mysql -u root -p
Enter password:
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 5
Server version: 5.6.19 MySQL Community Server (GPL)

Answer 6

I tried the following steps:

1. Log in as super user or use sudo
2. Open /etc/mysql/my.cnf using gedit
3. Find bind-address, and change its value to the database server host machine's IP address. For me, it was localhost or 127.0.0.1
4. Save and close the file.
5. Come back to terminal and execute sudo service mysql start

And it worked for me.
