The saltstack uses the C/s mode, and the server side is the master,client end of the salt, which communicates between Minion,minion and master through ZEROMQ Message Queuing. Master listens on 4505 and 4506 ports, 4505 is the master and Minion authenticated communication ports, and 4506 performs return information for commands that Master uses

Requirement Description: 1) if there is no Marshall user on a node with hundreds of Linux servers, add the user and replace the second field in the/etc/shadow column. If the user exists, replace the second field character of/etc/shadow. 2) check whether there is a sudo command on the node server. If there is a sudo command, it means it exists. Otherwise, install the sudo command. 3) enables the Marshall user to execute all the commands with the root permission. 1. Set up the
