I am running OSX right now and trying to run a mysqld process and seeing the following error:

 $ /usr/local/mysql/bin/mysqld --user=root
111026 11:05:08 [Warning] Can't create test file /usr/local/mysql-5.5.15-osx10.6-x86_64/data/XXX.lower-test

InnoDB: The error means mysqld does not have the access rights to

InnoDB: File operation call: 'open'.

I understand the problem is since I am not using sudo, my current user account does not have write access to

/usr/local/mysql-5.5.15-osx10.6-x86_64/data/

I am trying accomplish two different things

  1. Give the mysqld process write access to that directory without using chmod 700 or whatever. I am trying to use chown and it is not working

  2. Create a script so the mysqld process starts at boot-up

Can anyone help me?

Depending on the uid mysqld is using, chmod 700 on the data directory might not help. You may do the following:

  • chmod 777 /usr/local/mysql-5.5.15-osx10.6-x86_64/data/
  • Startup mysqld again
  • ls -l /usr/local/mysql-5.5.15-osx10.6-x86_64/data/ to identify the owner of the created files
  • chown OWNER /usr/local/mysql-5.5.15-osx10.6-x86_64/data
  • chmod 700 /usr/local/mysql-5.5.15-osx10.6-x86_64/data/
  • Also do change ownership group as well & do it recursively chgrp -R mysql data_folder – Senthil Kumar Vaithiyanathan Mar 21 '18 at 9:35
  • @SenthilKumarVaithiyanathan If the parent dir permissions are set to 0700, group permissions/ownership doesn't matter – nohillside Mar 21 '18 at 10:58
