Install MySQL 5.7 on macOS using Homebrew

MySQL_5-7_macOS.md

This is a fork of original gist https://gist.github.com/nrollr/3f57fc15ded7dddddcc4e82fe137b58e, with slight changes on pointing to 5.7 version branch, instead of 8 (latest default of MySQL in Hombrew).

Install MySQL 5.7 on macOS

This procedure explains how to install MySQL using Homebrew on macOS (Sierra 10.12 and up)

Install Homebrew

• Installing Homebrew is effortless, open Terminal and enter :
  $ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
• Note: Homebrew will download and install Command Line Tools for Xcode 8.0 as part of the installation process.

Install MySQL

At this time of writing, Homebrew has MySQL version 8 as default, but as we're aiming to get 5.7, we'll need to append @5.7 to the default package key:

• Enter the following command : $ brew info [email protected]
• Expected output: [email protected]: stable 5.7.22 (bottled) [keg-only]

To install MySQL enter : $ brew install [email protected]

Additional configuration

Homebrew

• Install brew services first : $ brew tap homebrew/services

• Load and start the MySQL service : $ brew services start [email protected].
  Expected output : Successfully started mysql (label: homebrew.mxcl.mysql)

• Check of the MySQL service has been loaded : $ brew services list ¹

• Force link 5.7 version - $ brew link [email protected] --force

• Verify the installed MySQL instance : $ mysql -V.
  Expected output : Ver 14.14 Distrib 5.7.22, for osx10.13 (x86_64)

MySQL

Open Terminal and execute the following command to set the root password:
mysqladmin -u root password 'yourpassword'

Important : Use the single ‘quotes’ to surround the password and make sure to select a strong password!

Database Management

To manage your databases, I recommend using Sequel Pro, a MySQL management tool designed for macOS.
Current version available: 1.1.2

Comments

¹ The brew services start [email protected] - instruction is equal to :

$ ln -sfv /usr/local/opt/mysql/*.plist ~/Library/LaunchAgents
$ launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

As mentioned by other users above, this gist is missing a few important steps:

1. Adding the mysql directory to PATH after installation in order to run mysql command: https://gist.github.com/operatino/392614486ce4421063b9dece4dfe6c21#gistcomment-2950061
2. Either removing the root password or making a my.cnf file to automatically log in: https://medium.com/@benmorel/remove-the-mysql-root-password-ba3fcbe29870

Since version 5.7, MySQL is secure-by-default:

• a random root password is generated upon installation; you need to read this password from the server log
• you have to change this password the first time you connect
• you cannot use a blank password because of the validate_password plugin

root

very thanks~
helpful~

Still seeing the "Can't connect to local MySQL server..."

Tried Greggle's link to fully remove a previous install of MySQL 8, but after a restart the problem persists

# brew services start [email protected]
==> Successfully started `[email protected]` (label: [email protected])

# launchctl list | grep mysql
-	0	[email protected]

Brew services is reporting the service started, but Launchctl is not showing a PID.

Here is the log output

lee@kezzico:~# tail /usr/local/var/mysql/kezzico.local.err 
2018-10-03T21:57:10.986146Z 0 [ERROR] Can't start server: can't check PID filepath: No such file or directory
2018-10-03T21:57:11.6NZ mysqld_safe mysqld from pid file /var/run/mysqld/mysqld.pid ended

Finally got the service to start by creating a folder for the PID, and setting the permission on the folder to global read/write/x.

# sudo mkdir /var/run/mysqld
# chmod 777 /var/run/mysqld

Not sure why this is necessary. There may be security implications to this. Hopefully someone has a better solution.

Also you can change the mysql folder permissions to the current user.

sudo chown -Rv "$USER":admin /usr/local/var/mysql

Works great until I attempt to create a password for root:

$ mysqladmin -u root password 'yourpassword'

I get the following error:

... Failed! Error: Column count of mysql.user is wrong. Expected 45, found 43. Created with MySQL 50615, now running 50732. Please use mysql_upgrade to fix this error.

Any advice would be much appreciated?

run this command, it will prompt a form about setting up root password

Did the trick, thanks!

Thanks a lot!!!

I followed the instructions and did a clean install.
I got to the same "mysqladmin" point, but failed differently...

% mysqladmin -u root password '---redacted---'
mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'@'localhost' (using password: YES)'

To get past this, here's what I ended up having to do:

• Enter mysql and add a password for “root” user:

  • mysql -u root -p
  • It will prompt for password. THERE IS NO PASSWORD YET, SO JUST HIT ENTER
  • you should get the mysql> prompt

• At the mysql> prompt:

  • mysql> use mysql;
  • mysql> update user set authentication_string=password("<desired root password>") where user="root";
  • mysql> exit

• Restart the service to pick up the change:

  • brew services stop [email protected]
  • brew services start [email protected]

Now, when you do mysql -u root -p it will prompt for password and accept the new password you set above.

I had to do below steps after following the given instructions:-
sudo mkdir /usr/local/var/mysql
sudo chmod 777 /usr/local/var/mysql
brew services restart [email protected]

When setting up my Apple M1 Macbook Pro I was experiencing the issue of the following error message being thrown:

Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

My fix was to modify the MySQL config file:

nano /usr/local/etc/my.cnf

Append the following lines:

tmpdir=/tmp
user=root

Then run:

brew services restart [email protected]

This fixed my issue, and I was then able to connect successfully with my DB client.

Thank you, It worked on macOS Monterey.

Not working for me on mac os m2 ventura.

I did start [email protected] and gives me Successfully started [email protected] (label: [email protected]) message. But, when I tried to view the list of services to check if it's really started, I got this status below which is stopped.

much good!

Any suggestions since 2024-08-01?
% brew install [email protected] Error: [email protected] has been disabled because it is not supported upstream! It will be disabled on 2024-08-01.

@milo-lamar Have you managed to resolve this

No but adjustments had already been made to allow 8.0 to work for me so I was allowed to move on with my life.. If worse comes to worse, you can find an old copy of 5.7 somewhere I'm sure.

@ibadk5304 I was able to get part of the way to installing 5.7 again, but ended up reaching an error I couldn't resolve. Like Milo, I was able to switch to 8.0, but if you can't, I hope this might get you partway there:

• Install Homebrew's packages locally: brew tap homebrew/core --force
• open /opt/homebrew/Library/Taps/homebrew/homebrew-core/Formula/m/[email protected] and comment out the line disabling the formula (line 22). In my experience, Homebrew kept overwriting this change, so you might have better luck copying the file to some new name instead.
• HOMEBREW_NO_INSTALL_FROM_API=1 brew install --build-from-source /opt/homebrew/Library/Taps/homebrew/homebrew-core/Formula/m/[email protected] Or use the new file copy if you created one in the last step.

This approach allowed MySQL to start installing, but I still ran into an error:

Error: An exception occurred within a child process:
  Errno::ENOENT: No such file or directory @ apply2files - /opt/homebrew/Cellar/[email protected]/5.7.44_1/data

... and I couldn't figure out how to solve that issue. The non-existent file here seems like it's something Homebrew is supposed to add during the installation process. When I created the file myself, Homebrew thought [email protected] was "already installed."

What I did here was to use instead [email protected], which is greatly compatible with MySQL 5.7 - so instead of using [email protected] you can just use [email protected] to replace it 🎉

brew tap homebrew/core --force
brew edit [email protected]
# Remove disable! line
HOMEBREW_NO_INSTALL_FROM_API=1 brew install [email protected]

@Pezmc you solution worked great. I tried upgrading to mysql 8 and had issues but I had already uninstalled 5.7 :(

Error: An exception occurred within a child process:
  Errno::ENOENT: No such file or directory @ apply2files - /opt/homebrew/Cellar/[email protected]/5.7.44_1/data

@newtrat To fix this, follow instructions from @Pezmc and also add this just before the system "cmake" line:

mkdir prefix/"data"

HOMEBREW_NO_INSTALL_FROM_API=1 brew install [email protected]

this works for me!

Thanks, everyone, for this thread! The steps from @Pezmc worked great for me. The only change I had to make was updating depends_on "[email protected]" to depends_on "openssl@3" when modifying the mysql formula in my set up.

I didn’t experience any breaking changes with this patch, but your mileage may vary.
