Assuming you are Database Root
Checking if SELinux is enabled…Its not (good)!
Reading /etc/asterisk/asterisk.conf…Done
Checking if Asterisk is running and we can talk to it as the ‘asterisk’ user…Yes. Determined Asterisk version to be: 14.7.6
Preliminary checks done. Starting FreePBX Installation
Checking if this is a new install…Yes (No /etc/freepbx.conf file detected)
Database Root installation checking credentials and permissions…Error!
Invalid Database Permissions. The error was: SQLSTATE[HY000] [2002] No such file or directory

can anyone help on this?
