Hello, Is this script supposed to be runnable as a normal (i.e., non-root) user? In MySQL 5.6 there is logic that prevents the chown() of the mysql data dir when running as non-root. MariaDB 10.1.8 doesn’t seem to have this logic, so the script fails when chown() fails. Is this change intended? We have tests that verify functionality of user-created, UNIX-socket-only MySQL/MariaDB servers. These work on MySQL 5.6 but not on MariaDB 10.1. Here is the command-line output: --------------- ~/temp $ /usr/bin/mysql_install_db --datadir=mysqldata chown: changing ownership of `mysqldata': Operation not permitted Cannot change ownership of the database directories to the 'mysql' user. Check that you have the necessary permissions and try again. bash: __git_ps1: command not found --------------- Thank you for your time! -Felipe Gasper Houston, TX
