How to Connect or Disconnect from the MYSQL Server

To connect to the server, you will usually need to provide a MySQL user name when you invoke mysql and, most likely, a password. If the server runs on a machine other than the one where you log in, you will also need to specify a host name. Contact your administrator to find out what connection parameters you should use to connect (that is, what host, user name, and password to use). Once you know the proper parameters, you should be able to connect like this:

Code:
shell> mysql -h host -u user -p
Enter password: ********
host and user represent the host name where your MySQL server is running and the user name of your MySQL account. Substitute appropriate values for your setup. The ******** represents your password; enter it when mysql displays the Enter password: prompt.

If that works, you should see some introductory information followed by a mysql> prompt:

Code:
shell> mysql -h host -u user -p
Enter password: ********
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 25338 to server version: 5.0.78-standard

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql>

Re: How to Connect or Disconnect from a MYSQL Server

The mysql> prompt tells you that mysql is ready for you to enter commands.

If you are logging in on the same machine that MySQL is running on, you can omit the host, and simply use the following:

Code:
shell> mysql -u user -p
If, when you attempt to log in, you get an error message such as ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2), it means that that MySQL server daemon (Unix) or service (Windows) is not running.

Some MySQL installations allow users to connect as the anonymous (unnamed) user to the server running on the local host. If this is the case on your machine, you should be able to connect to that server by invoking mysql without any options:

Code:
shell> mysql
After you have connected successfully, you can disconnect any time by typing QUIT (or \q) at the mysql> prompt:

Code:
mysql> QUIT
Bye
On Unix, you can also disconnect by pressing Control-D.
