how to log in to mysql and query the database from linux terminal

1.- How do I get mysql prompt in linux terminal?

mysql -u root -p

At the Enter password: prompt, well, enter root's password :)

You can find further reference by typing mysql --help or at the online manual.

2. How I stop the mysql server from linux terminal?

It depends. Red Hat based distros have the service command:

service mysqld stop

Other distros require to call the init script directly:

/etc/init.d/mysqld stop

3. How I start the mysql server from linux terminal?

Same as #2, but with start.

4. How do I get mysql prompt in linux terminal?

Same as #1.

5. How do I login to mysql server from linux terminal?

6. How do I solve following error?

Same as #1.

To your first question:

mysql -u root -p

or

mysqladmin -u root -p "your_command"

depending on what you want to do. The password will be asked of you once you hit enter! I'm guessing you really want to use mysql and not mysqladmin.

For restarting or stopping the MySQL-server on linux, it depends on your installation, but in the common debian derivatives this will work for starting, stopping and restarting the service:

sudo /etc/init.d/mysql startsudo /etc/init.d/mysql stopsudo /etc/init.d/mysql restartsudo /etc/init.d/mysql status

In some newer distros this might work as well if MySQL is set up as a deamon/service.

sudo service mysql startsudo service mysql stopsudo service mysql restartsudo service mysql status

But the question is really impossible to answer without knowing your particular setup.

I assume you are looking to use mysql client, which is a good thing and much more efficient to use than any phpMyAdmin alternatives.

The proper way to log in with the commandline client is by typing:

mysql -u username -p

Notice I did not type the password. Doing so would of made the password visible on screen, that is not good in multi-user environnment!

After typing this hit enter key, mysql will ask you for your password.

Once logged in, of course you will need:

use databaseName;

to do anything.

Good-luck.
