Saltstack (hostname renamed)

The machine already exists in the salt, in order to standardize, need to rename this batch of host

Operation Flow: Remove the machine from master, modify the host name of the machine, rename the minion_id and PKI directories in the/etc/salt directory, and restart the Salt-minion service (after the Mster segment can monitor the host again, can delete the file renamed above)

Environment: http://www.cnblogs.com/zzzhfo/p/6126223.html

Rename the salt-client-01 to salt-minion-01

• Remove salt-client-01 from the salt-server.
