MYSQL no se ejecuta en el sistema operativo Ubuntu - Error 2002

I am a novice to mysql DB. I am trying to run the MYSQL Server on Ubuntu 10.04. Through Synaptic Package Manager I am have installed the mysql version: mysql-client-5.1

I wonder that how was the database password set for the mysql-client software that I installed through the above way.It would be nice if you could enlighten me on this.

When I tried running this database, I encountered the error given below:

mohnish@mohnish-laptop:/var/lib$ mysql
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
mohnish@mohnish-laptop:/var/lib$ 

I referred to a pregunta similar posted by another user. I didn't find a solution through the proposed answers.

For instance when I tried the solutions posted for the similar question I got the following:

mohnish@mohnish-laptop:/var/lib$ service start mysqld
start: unrecognized service
mohnish@mohnish-laptop:/var/lib$ ps -u mysql

I even tried referring to http://forums.mysql.com/read.php?11,27769,84713#msg-84713 but couldn't find anything useful.

Please let me know how I could tackle this error.

Muchas gracias..

mohnish@mohnish-laptop:/var/lib$ service mysqld start 

looks like you did not install the mysql server package

sudo apt-get install mysql-server

debería ayudar

Thanks for your answer and for the exact command I needed to use to get the server installed. I was not able to find this in the synaptic manager.. I wonder why.. but anyways the terminal did the job for me.. - Bodhisattva

This really belongs on serverfault.

Anyway, you installed the mysql-client package but what you need is the mysql-server package. The client is just the command-line client, while the server is what runs the server itself.

After installing it on Ubuntu, you can start and stop it as root via:

/etc/init.d/mysql start
/etc/init.d/mysql stop

Thanks for your answer & the extra info... I shall be more careful next time while posting questions.. - Bodhisattva

Use the following commands

dpkg -l mysql* | grep ii | awk '{ print $2 }' | sudo xargs apt-get remove --purge -y 

&&

sudo apt-get install mysql-server
