Why install the MySQL CLI?

The standalone MySQL client lets you test migrations, run federated queries, and move data between PostgreSQL and MySQL without installing a full MySQL server.

Which package should I choose?

Use the mysql-client package on Linux, the MySQL Community installer on Windows, and Homebrew on macOS. All ship the mysql binary plus helpful utilities like mysqldump.

How do I install on macOS with Homebrew?

Run brew install mysql-client.Add export PATH="/opt/homebrew/opt/mysql-client/bin:$PATH" to your shell profile so the mysql command is globally available.

How do I install on Ubuntu/Debian?

Update apt, then run sudo apt-get install mysql-client.The package includes mysql, mysqldump, and man pages.

Fedora & RHEL?

Execute sudo dnf install mysql (or sudo yum install mysql on older releases) to pull the client-only RPMs.

How do I install on Windows?

Download the "MySQL Community x64" installer, choose "MySQL Shell" and "MySQL Server & Client" optional components, then follow the wizard. Add the install folder to the PATH.

How do I verify the installation?

Run mysql --version.A version string such as mysql Ver 8.0.36 for macOS on x86_64 confirms success.

How can I connect to an ecommerce database?

Use mysql -u readonly -p -h db.prod.local ecommerce. After entering the password you can query tables like Customers or Orders.

How do I export data for PostgreSQL?

Use mysqldump -u readonly -p --no-create-info ecommerce Customers Orders | psql postgres://user@localhost/shop.This streams data directly from MySQL to PostgreSQL.

Best practices for secure use?

Create least-privilege users, avoid saving plaintext passwords, and prefer SSL connections with --ssl-mode=REQUIRED.

What common errors should I avoid?

Ensure the client version is not newer than the server by more than two major releases, and always append the -h flag when connecting to remote hosts.

How to Install the MySQL CLI in PostgreSQL Syntax


mysql [OPTIONS] [database]
--user, -u <user_name>           # Username, e.g., 'analytics'
--password, -p[=<password>]      # Password prompt or inline value
--host, -h <hostname>            # MySQL server host
--port, -P <port_number>         # Port (default 3306)
--execute, -e "SQL"              # Run one-off query and exit
--ssl-mode=REQUIRED              # Enforce encrypted session

Example: 
mysql -u analytics -p -h db.shop.local -e "SELECT id, name, email FROM Customers LIMIT 10;" ecommerce

Common Mistakes

Skipping PATH updates after Homebrew install on macOS. Why wrong: The mysql command won’t be found in new shells. Fix: Add /opt/homebrew/opt/mysql-client/bin to PATH.
Using older mysql-client 5.x against an 8.x server. Why wrong: Authentication defaults differ, causing "caching_sha2_password" errors. Fix: Upgrade the client or enable legacy auth on the server.
