Resolve the current warning prompt

Tcp-backlog

The backlog argument defines the maximum length to which the queue of pending connections for sockfdmay grow. If a connection request arrives when the queue is full, the client may receive an error with an indication of ECONNREFUSED or, if the underlying protocol supports retransmission, the request may be ignored so that a later reattempt at connection succeeds.

The backlog parameter controls the queue value after the server side receives the client ack confirmation number during the three-way handshake.

[root@centos ~] # echo 511 > / proc/sys/net/core/somaxconnvm.overcommit_memory

0. Indicates that the kernel will check whether there is enough memory available for the application process; if there is enough memory available, the memory request is allowed; otherwise, the memory request fails and the error is returned to the application process. 1. Indicates that the kernel allows all physical memory to be allocated, regardless of the current memory state. 2. Indicates that the kernel allows more than the sum of all physical memory and swap space to be allocated

[root@centos ~] # echo "vm.overcommit_memory = 1" > / etc/sysctl.conftransparent hugepage large page memory allocation needs to be turned off and redis is responsible for memory management. [root@centos ~] # echo never > / sys/kernel/mm/transparent_hugepage/enabled
