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

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

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  amp  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

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

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

If mysql is already installed Stop mysql completely   mysql server stop  lt -- may need editing based on your version ps -ef   grep mysql  lt -- lists processes with mysql in their name kill  PID   lt -- kill the processes by PID  Remove files   Instructions above are good   I ll add   sudo find    -name  quot  mysql  quot  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  lt -- dependency for mysql  useful sudo brew install openssl  lt -- dependency for mysql  useful sudo brew info mysql  lt -- skim through this    it gives you some idea of what s coming next sudo brew install mysql --with-embedded  say done  lt -- 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   lt -- mysql wouldn t work for me until I ran this command sudo mysql server start  lt -- 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

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

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

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

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
