" section is used to provide default parameters for all other configuration segments. The default configuration parameters can be reset by the next "defaults. The frontend segment is used to define a series of listening sockets that can accept client requests and establish a connection with it. The "backend" section defines a series of "backend" servers. The proxy forwards requests from the corresponding clients to these servers. The "listen" section defines a complete proxy by associating the "

Semmns parameter values are official document defaults, the process is set to 8000 per business requirement and the instance cannot be started. After you set the Semmni and Semmns parameter values to a value of twice, and then test the process to 16000, you also cannot start the instance.It can be seen that the SEM signal volume and processes have some kind of association, and at this time to boot to the Nomount state, the actual and no user connection, indicating that the semaphore is pre-allo
