It is believed that many inexperienced people have no idea about how to install salt/salt-api in DevOps. Therefore, this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

SaltStack is a service model based on Cramp S architecture. In SaltStack architecture, the server side is called Master and the client side is called Minion. The traditional CAccord S architecture is that the client sends a request to the server, and the server receives the request and then returns it to the client after processing. There is not only the traditional SaltStack S architecture service model, but also the publish and subscribe (pub/sub) service model in the message queue. This makes the SaltStack application scenario richer. At present, in the actual environment, SaltStack's C _ paw S architecture is generally used for configuration management.

Both Master and Minion run in daemon mode, always listening on the ports of ret_port (accept minion requests, default port number: 4506) and publish_port (publish messages, default port number: 4505) defined in the configuration file. When Minion is running, it will automatically connect to the Master address ret_port port defined in the configuration file for connection authentication. The default client request id is the value taken by socket.getfqdn (), and you can also change the id value of Minion before Minion starts.
