MySQL

ApplicationOracle

Also called mysql server, mysqld

OracleProductivity

Oracle's MySQL database server. On Windows the server process is mysqld.exe. Workbench is the official GUI. It is not PostgreSQL.

What you need to know

MySQL is mysqld.exe. PostgreSQL is postgres.exe.

mysqld.exe is Oracle's MySQL server. The installer can add Workbench. PostgreSQL is a different server. XAMPP's bundled MySQL or MariaDB is a learning stack, not always this official install.

What is it?: MySQL database server
Same as PostgreSQL?: No. Different engine and exe
Is Workbench the server?: No. mysqld.exe is the server

Feex says

If mysqld.exe is running, I treat it as the MySQL server. I would not stop postgres.exe to free it, and I would not uninstall Workbench to remove the server.

What is MySQL?

MySQL is the database server. mysqld.exe is the Windows process. It is not PostgreSQL, not Workbench, and not XAMPP by itself.

If you have never used it

If a class said install MySQL, use the MySQL Installer from dev.mysql.com/downloads/installer. mysqld.exe is the server. Workbench is a checkbox for the GUI. PostgreSQL is a different engine with postgres.exe. XAMPP also bundles a database. That copy is not this official server unless you pointed at it on purpose.

What is it used for?

Store relational data

Schemas on port 3306 by default. postgres.exe defaults to 5432.

Windows service

MySQL80 or similar. That is not postgresql-x64-##.

Optional Workbench

The installer can add MySQLWorkbench.exe. DBeaver is a different GUI.

Who is it for?

Developers whose stack is MySQL
Students whose README assumes port 3306
Anyone who installed Postgres and wondered why mysql was not a command

Current status

MySQL (1995) is a current database server from Oracle. The vendor still points Windows users at https://dev.mysql.com/downloads/installer/.

How old is it?

MySQL dates to 1995. Oracle owns the current product. MySQL 8.0 is the usual Windows line. A 5.0 query browser screenshot is history. MariaDB is a fork, not this installer.

Versions

Major channels first. Exact build numbers are not all verified here.

MySQL 8.0

MySQL Installer bundle

System requirements

Values follow the publisher's public guidance. Workload still changes the real need.

Minimum

Minimum system requirements
Operating system	A current 64-bit Windows 10 or Windows 11 release, per Oracle's MySQL Installer
RAM	4 GB class is a common comfortable floor for a local 8.0 server plus Windows

Resource profile

CPU demand: Follows what you open inside the app
RAM demand: Follows documents, tabs, or libraries

Installed processes

These executables belong to this product when it is installed.

Installed processes
mysqld.exe	MySQL server

Startup components

The installer can start the service at boot. That is mysqld.exe, not Workbench.

File locations

Common MySQL locations
Typical install	C:\Program Files\MySQL\MySQL Server 8.0\

File formats

SQLdump

Common problems

Port 3306 already in use

XAMPP or another MySQL service can steal it. Postgres on 5432 is a different conflict.

People uninstall Workbench and think MySQL is gone

MySQLWorkbench.exe is the GUI. mysqld.exe can stay.

Getting unstuck

Install from dev.mysql.com/downloads/installer

Oracle hosts the installer. An Oracle account may be required. A random MySQL zip is junk.

Services.msc: MySQL80 or the name you picked

postgresql-x64-## is the other engine.

mysql CLI or Workbench to test a login

pgAdmin will not speak MySQL as its first protocol.

Alternatives

PostgreSQL if the stack is Postgres. MariaDB if you want that fork. XAMPP if you only needed a class stack. Workbench or DBeaver for a GUI.

Official help and downloads

Start with the vendor. Random exe sites are not a support channel.

Related hardware

The server wants RAM for the buffer pool and disk for datadir. A GPU is irrelevant.
