MySQL - Connect with CLI

Connect to your Public Cloud Databases for MySQL using the Command Line Interface (CLI)

Last updated 8th March 2022


Public Cloud Databases allow you to focus on building and deploying cloud applications while OVHcloud takes care of the database infrastructure and maintenance in operational conditions.

This guide explains how to connect to a MySQL database instance with a Command Line Interface (CLI).



To interact correctly with the MySQL instance, we need to first install something called a MySQL client, in order to connect and control the MySQL service remotely. It's a Client-Server interaction.


Installing the MySQL client

Please note that a MySQL client is natively integrated in the MySQL software package but it does not allow the use of Service URI.

You first need to install a software to interact with your MySQL instance remotely. This official software can be installed on various client machines such as your own computer, a VPS or a virtual machine. The only rule is to be able to reach the public network (Internet) and have sufficient rights to install it.

In order to do so and depending on your configuration, you may need to follow official MySQL documentation to install MySQL Shell (mysqlsh), more powerful compared to MySQL Client (mysql).

MySQL Shell is not mandatory but much more convenient to use compared to standard MySQL Clients, since you can connect with Service URI instead of individual parameters.

Follow the steps here after selecting Windows, MacOS or Linux as operating system:

We are now ready to learn how to connect to our MySQL instance.


We will now follow official MySQL documentation to perform our first connection.

In your CLI, type mysqlsh --version. The result should look like this:

laptop$mysqlsh --version
/snap/mysql-shell/29/bin/mysqlsh   Ver 8.0.23 for Linux on x86_64 - for MySQL 8.0.23 (Source distribution)

It means that mysqlsh is correctly installed and working properly. If you do not see something like this result, please go back to the previous step and reinstall MySQL shell.

Connect to your MySQL instance

We will follow official MySQL documentation:

To perform a connection, simply type mysqlsh --sql followed by the Service URI:

laptop$mysqlsh --sql "mysql://<username>:<password@<hostname>t<port>/defaultdb?ssl-mode=REQUIRED"

Don't forget you need to modify the username, password, hostname and port. In our example, it will look like this:

laptop$mysqlsh --sql "mysql://"

Once connected correctly, you should see something similar to:

MySQL Shell 8.0.23

Congratulations! You are now fully able to interact with your MySQL instance!

MySQL client usage

Once connected, you can manage your MySQL instance with built-in MySQL client methods.

Please follow the official MySQL documentation.

To verify:

  • SHOW DATABASES; will list all the databases;
  • select * from mysql.user; will display information about existing users.

In our example, it will look like this:

mysql-sql [defaultdb]> SHOW DATABASES;
| Database           |
| defaultdb          |
| information_schema |
| mysql              |
| performance_schema |
| sys                |
5 rows in set (0.0046 sec)
defaultdb=> \h CREATE DATABASE
Description: create a new database
    [ [ WITH ] [ OWNER [=] user_name ]
           [ TEMPLATE [=] template ]
           [ ENCODING [=] encoding ]
           [ LOCALE [=] locale ]
           [ LC_COLLATE [=] lc_collate ]
           [ LC_CTYPE [=] lc_ctype ]
           [ TABLESPACE [=] tablespace_name ]
           [ ALLOW_CONNECTIONS [=] allowconn ]
           [ CONNECTION LIMIT [=] connlimit ]
           [ IS_TEMPLATE [=] istemplate ] ]
