MySQL Question

Mysql without root privilege

How do I start mysql without having root privileges/write access to tool area ?
I am getting following error

host13:~/JS> mysqld start

You can move MySQL data directory to where you are able to write, and then specify it in /etc/my.cnf (or possibly another location depending on your system defaults), the parameter is datadir.

If your data directory has not yet been initialized (in which case mysqld will complain about missing privilege tables) you can create them like this:

mysql_install_db --datadir=$path_to_new_datadir
