Check if the sock file in question is there at all - on my system, it is named mysqld.sock - on letter 'd' more than in your error message. If you quoted the message correctly, then perhaps the sock file has another name and you have to change the configuration of nwnx. Otherwise, if the sock file is not present, check if mysql is running at all: at a command line type:
ps -Af|grep -i [m]ysql
and check the output.
Bear in mind, though, that I know nwn and Linux very well but don't know much about nwnx and persistent world setups.
