brew install mysql on macOS

Question

I'm trying to setup up MySQL on mac os 10.6 using Homebrew by brew install mysql 5.1.52.

Everything goes well and I am also successful with the mysql_install_db.
However when I try to connect to the server using:

/usr/local/Cellar/mysql/5.1.52/bin/mysqladmin -u root password 'mypass'

I get:

 /usr/local/Cellar/mysql/5.1.52/bin/mysqladmin: connect to server at 'localhost' failed error: 'Access denied for user 'root'@'localhost' (using password: NO)'

I've tried to access mysqladmin or mysql using -u root -proot as well,
but it doesn't work with or without password.

This is a brand new installation on a brand new machine and as far as I know the new installation must be accessible without a root password. I also tried:

/usr/local/Cellar/mysql/5.1.52/bin/mysql_secure_installation

but I also get

 ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

See also: apple.stackexchange.com/a/199747/152271 ... it's not brew install, but it worked for me when none of the answers here did — sudo rm -rf slash

I think one can end up in this position with older versions of mysql already installed. I had the same problem and none of the above solutions worked for me. I fixed it thus:

Used brew's remove & cleanup commands, unloaded the launchctl script, then deleted the mysql directory in /usr/local/var, deleted my existing /etc/my.cnf (leave that one up to you, should it apply) and launchctl plist

Updated the string for the plist. Note also your alternate security script directory will be based on which version of MySQL you are installing.

Step-by-step:

brew remove mysql brew cleanup launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist rm ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist sudo rm -rf /usr/local/var/mysql

I then started from scratch:

installed mysql with brew install mysql

ran the commands brew suggested: (see note: below)

unset TMPDIR mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp

Start mysql with mysql.server start command, to be able to log on it

Used the alternate security script:

/usr/local/Cellar/mysql/5.5.10/bin/mysql_secure_installation

Followed the launchctl section from the brew package script output such as,

#start launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist #stop launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

Note: the --force bit on brew cleanup will also cleanup outdated kegs, think it's a new-ish homebrew feature.

Note the second: a commenter says step 2 is not required. I don't want to test it, so YMMV!

Great answer, thanks! One thing to add: Though it is mentioned in the answer, I missed it and in so doing lost about 6 hours trying to get set up on Lion OSX. Make absolutely sure that you delete the old mysql directory at /usr/local/var/mysql if you have a previous version of MySql before you reinstall. Otherwise you will not be able to log in as root initially to set the password and you will spend a lot of time yelling at your computer.
go into ~/Library/LaunchAgents to see what the .plist file for mysql is actually called - in my case it was installed by homebrew so you need to modify the above uninstall procedure.
Because this thread is old, the "launchctl unload" line above is now wrong. The file homebrew installs is not longer called "com.mysql.mysqld.plist", it is called "homebrew.mxcl.mysql.plist". The line should now read "launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist"
I have` [~/Library/LaunchAgents]$ ls com.adobe.ARM.202f4087f2bbde52e3ac2df389f53a4f123223c9cc56a8fd83a6f7ae.plist com.mysql.mysqld.plist com.facebook.videochat.ava.plist homebrew.mxcl.postgresql.plist` under ` ~/Library/LaunchAgents` but unloading them gives launchctl: Couldn't stat("com.mysql.mysqld.plist"): No such file or directory
mysql_install_db can now be omitted, brew creates the server automatically in the right directoy.

Here are detailed instructions combining getting rid of all MySQL from your Mac then installing it The Brew Way as Sedorner wrote above:

Remove MySQL completely per The Tech Lab

ps -ax | grep mysql
stop and kill any MySQL processes
sudo rm /usr/local/mysql
sudo rm -rf /usr/local/var/mysql
sudo rm -rf /usr/local/mysql*
sudo rm ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/My*
launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
edit /etc/hostconfig and remove the line MYSQLCOM=-YES-
rm -rf ~/Library/PreferencePanes/My*
sudo rm -rf /Library/Receipts/mysql*
sudo rm -rf /Library/Receipts/MySQL*
sudo rm -rf /private/var/db/receipts/*mysql*
sudo rm -rf /tmp/mysql*
try to run mysql, it shouldn't work

Brew install MySQL per user Sedorner from this StackOverflow answer

brew doctor and fix any errors
brew remove mysql
brew cleanup
brew update
brew install mysql

unset TMPDIR

 mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp # whoami is executed inline

mysql.server start
run the commands Brew suggests, add MySQL to launchctl so it automatically launches at startup

mysql should now work and be running all the time as expected

Godspeed.

I also got bitten by doing all of the above without removing /tmp/mysql.sock first.
Thanks, +1. Couple comments: you say to sudo rm ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist, then a few steps later you attempt to launchctl unload that file...but it won't be there, because you deleted it. Also, brew install mysql ran the mysql_install_db step for me, no need to do it twice.
Confirmed - whoami is my name (I used root). This worked great.
Note that /etc/hostconfig does not exist on Yosemite and beyond (superuser.com/questions/850974/…)
This worked for me also, I was having 'Plugin is not installed' issues when I tried mysql -u root. The only step that seemed to not work for me was mysql_install_db --verbose --user=whoami--basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp due to unrecognised options.

Had the same problem. Seems like there is something wrong with the set up instructions or the initial tables that are being created. This is how I got mysqld running on my machine.

If the mysqld server is already running on your Mac, stop it first with:

launchctl unload -w ~/Library/LaunchAgents/com.mysql.mysqld.plist

Start the mysqld server with the following command which lets anyone log in with full permissions.

mysqld_safe --skip-grant-tables

Then run mysql -u root which should now let you log in successfully without a password. The following command should reset all the root passwords.

UPDATE mysql.user SET Password=PASSWORD('NewPassword') WHERE User='root'; FLUSH PRIVILEGES;

Now if you kill the running copy of mysqld_safe and start it up again without the skip-grant-tables option, you should be able to log in with mysql -u root -p and the new password you just set.

This worked for me! I started guessing the password before I tried this too and the password ended up being 'password'. So try that.
Launching mysqld_safe without the grant tables worked for me. However, the UPDATE did not work since I do not have any records on select * from mysql.user; Since we are already logged in as root, we can simply insert one for root by running GRANT ALL PRIVILEGES ON . TO 'root'@'localhost' IDENTIFIED BY 'whatever'; FLUSH PRIVILEGES;
I was using the stop service/script, and it kept restarting. Was that because I never unloaded the LaunchAgent? (doh)
What works for me was something similar to what you make. In the part that you updated the password of the user, I had to make: use mysql; update user set authentication_string=password('1111') where user='root'; As in: stackoverflow.com/a/31122246/1328261

Homebrew

First, make sure you have homebrew installed
Run brew doctor and address anything homebrew wants you to fix
Run brew install mysql
Run brew services restart mysql
Run mysql.server start
Run mysql_secure_installation

If brew installed MySQL 5.7, the process is a bit different than for previous versions. In order to reset the root password, proceed as follows:

sudo rm -rf /usr/local/var/mysql mysqld --initialize

A temporary password will be printed to the console and it can only be used for updating the root password:

mysql.server start echo "ALTER USER 'root'@'localhost' IDENTIFIED BY 'my-new-password';" | mysql -uroot --password=TEMPORARY_PASSWORD

I can see the temp password generated but when I try to run mysql, I get: ERROR! The server quit without updating PID file (/usr/local/var/mysql/XXXXX.local.pid). and when I do mysql -u root, the password is not accepted.

markphd Over a year ago

I successfully installed mysql 5.7.9 using the dmg installer which prompted me a window that it generated a temp password for me. And now mysql is working correctly. Too bad I had to spend huge amount of time just to get it working on a brand new Macbook. :|

oshaiken Over a year ago

@forloop 1. ps -ef | grep mysql 2. kill -9 pid 3. mysql.server start

Test Test Over a year ago

for me, above reseting/altering of password did not work. I had to log into mysql using temporary password then run alter command 1. mysql -u root -p <temp-password> 2. ALTER USER 'root'@'localhost' IDENTIFIED BY 'New-Password';

Darren Newton · Accepted Answer · 2010-12-26 05:03:14Z

Okay I had the same issue and solved it. For some reason the mysql_secure_installation script doesn't work out of the box when using Homebrew to install mysql, so I did it manually. On the CLI enter:

mysql -u root

That should get you into mysql. Now do the following (taken from mysql_secure_installation):

UPDATE mysql.user SET Password=PASSWORD('your_new_pass') WHERE User='root'; DELETE FROM mysql.user WHERE User='root' AND Host NOT IN ('localhost', '127.0.0.1', '::1'); DELETE FROM mysql.user WHERE User=''; DELETE FROM mysql.db WHERE Db='test' OR Db='test\\_%' DROP DATABASE test; FLUSH PRIVILEGES;

Now exit and get back into mysql with: mysql -u root -p

This solution is not working for me because mysql -u root is not taking me to mysql prompt. It says Access denied for user 'root'@'localhost' (using password: NO)

I had the same problem just now. If you brew info mysql and follow the steps it looks like the root password should be new-password if I remember correctly. I was seeing the same thing you are seeing. This article helped me the most.

It turned out I didn't have any accounts created for me. When I logged in after running mysqld_safe and did select * from user; no rows were returned. I opened the MySQLWorkbench with the mysqld_safe running and added a root account with all the privs I expected. This are working well for me now.

If mysql is already installed

Stop mysql completely.

mysql.server stop <-- may need editing based on your version
ps -ef | grep mysql <-- lists processes with mysql in their name
kill [PID] <-- kill the processes by PID

Remove files. Instructions above are good. I'll add:

sudo find /. -name "*mysql*"
Using your judgement, rm -rf these files. Note that many programs have drivers for mysql which you do not want to remove. For example, don't delete stuff in a PHP install's directory. Do remove stuff in its own mysql directory.

Install

Hopefully you have homebrew. If not, download it.

I like to run brew as root, but I don't think you have to. Edit 2018: you can't run brew as root anymore

sudo brew update
sudo brew install cmake <-- dependency for mysql, useful
sudo brew install openssl <-- dependency for mysql, useful
sudo brew info mysql <-- skim through this... it gives you some idea of what's coming next
sudo brew install mysql --with-embedded; say done <-- Installs mysql with the embedded server. Tells you when it finishes (my install took 10 minutes)

Afterwards

sudo chown -R mysql /usr/local/var/mysql/ <-- mysql wouldn't work for me until I ran this command
sudo mysql.server start <-- once again, the exact syntax may vary
Create users in mysql (http://dev.mysql.com/doc/refman/5.7/en/create-user.html). Remember to add a password for the root user.

TL;DR

MySQL server might not be running after installation with Brew. Try brew services start mysql or just mysql.server start if you don't want MySQL to run as a background service.

Full Story:

I just installed MySQL (stable) 5.7.17 on a new MacBook Pro running Sierra and also got an error when running mysql_secure_installation:

Securing the MySQL server deployment. Enter password for user root: Error: Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

Say what?

According to the installation info from Brew, mysql_secure_installation should prompt me to... secure the installation. I figured the MySQL server might not be running and rightly so. Running brew services start mysql and then mysql_secure_installation worked like a charm.

Just to add something to previous answers - When upgrading from MySql 5.6 to MySql 8.0, I followed the steps provided here to make a clean uninstall, yet I got following errors

2019-11-05T07:57:31.359304Z 0 [ERROR] [MY-000077] [Server] /usr/local/Cellar/mysql/8.0.18/bin/mysqld: Error while setting value 'ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION' to 'sql_mode'. 2019-11-05T07:57:31.359330Z 0 [ERROR] [MY-013236] [Server] The designated data directory /usr/local/var/mysql is unusable.

Took me some time to figure it out. Found a clue here: https://discourse.brew.sh/t/clean-removal-of-mysql/2251

So, the key to my problem was removing /usr/local/etc/my.cnf file after uninstall. After that one last step, MySql finally started working.

the problem is that i can't access the mysql server at all after the installation by brew. I can start it, but it won't let me in as root with or without password. (therefore i can't create other users or manage permissions.. or have I not understood you right?

Alexander Millar · Accepted Answer · 2013-08-09 13:00:30Z

I had the same issue after I tried to restart mysql.

I use the following two aliases in my .profile for convenience

alias mysql-stop='launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist' alias mysql-start='launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist'

After stoping mysql and then trying to restart I experienced the issue you were having. I looked into the launchctl load and it was reporting a “nothing found to load” error.

After a quick search I found this..

http://www.daveoncode.com/2013/02/01/solve-mac-osx-launchctl-nothing-found-to-load-error/

So I updated me mysql-start alias as follows

alias mysql-start='launchctl load -w -F ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist'

This solved my issue which may be useful for you.

Brew now supports a services command, so these can be replaced with brew services stop mysql and brew services start mysql respectively.

None of the above answers (or any of the dozens of answers I saw elsewhere) worked for me when using brew with the most recent version of mysql and yosemite. I ended up installing a different mysql version via brew.

Specifying an older version by saying (for example)

brew install mysql56

Worked for me. Hope this helps someone. This was a frustrating problem that I felt like I was stuck on forever.

Yes, this will work, but if you wanted to install MySQL 5.7 (as currently done by brew install mysql), you could follow the directions in my answer stackoverflow.com/a/33924648/133106

The "Base-Path" for Mysql is stored in /etc/my.cnf which is not updated when you do brew upgrade. Just open it and change the basedir value

For example, change this:

[mysqld] basedir=/Users/3st/homebrew/Cellar/mysql/5.6.13

to point to the new version:

[mysqld] basedir=/Users/3st/homebrew/Cellar/mysql/5.6.19

Restart mysql with:

mysql.server start

Try solution I provided for MariaDB, high change that it works with MySQL also:

MacOSX homebrew mysql root password

In short, try to login with your username! not root.

Try same name as your MacOS account username, e.g. johnsmit.

To login as root, issue:

mysql -u johnsmit

deleting /opt/homebrew/var/mysql did the job. Apparently there were mysql data (including password) so all this manipulations described above were to no avail.
