Salt master Configuration

Cat /etc/salt/master| grep ' # '  192.168auto_accept:true file_roots:  Base:    -/data/salt/ Base

The custom grains has two methods, the first minion-side configuration, but requires the restart Minion to take effect, the second is configured on the master side, takes effect after synchronization, does not need to restart Master or minion

This example customizes the grains with the master end of the second method

Create the _grains directory under the Salt Base (/data/salt/base) directory, under the _grains directory nginx.py
