How to connect to MySQL server?

To connect to a MySQL server, you can use the mysql command-line client. Here’s how to do it:

Open your terminal.
Use the following command to connect:
```
mysql -u username -p
```
Replace username with your MySQL username (e.g., root).
Enter your password when prompted.

After you run the command, you will be prompted to enter the password for the specified user. Type your password and press Enter.
If the connection is successful, you will see the MySQL prompt:
```
mysql>
```

From here, you can execute SQL commands and queries.

To connect as the root user, you would run:

mysql -u root -p

Then enter the password when prompted. If you want to connect to a specific database right away, you can add the database name at the end:

mysql -u username -p database_name

Ensure that the MySQL server is running before attempting to connect.
If you are connecting to a remote MySQL server, you can specify the host with the -h option:
```
mysql -h hostname -u username -p
```

Replace hostname with the IP address or domain name of the MySQL server.
