1. The rlimit_files value in the php-fpm configuration file must be consistent with the number of open connections of the system.

1) view the number of opened system files

[Root @ iZ94eveq0q4Z ~] # Ulimit-n
65535

2) Check the rlimit_files value in the php-fpm configuration file.

; Set open file descriptor rlimit # rlimit sets the open file descriptor
; Default Value: system defined value
Rlimit_files = 65535
If the two values are different, set them to the same

The method is as follows:

3) set the number of open files in the system

[Root @ hotdata ~] # Ulimit-HSn 65535
[Root @ hotdata ~] # Ulimit-n
65535
[Root @ hotdata ~] #

Restart the php-fpm service after setting.

2. Set request_terminate_timeout = 0 to 0.

; The timeout for serving a single request after which the worker process will
; Be killed. This option shocould be used when the 'max _ execution_time 'ini option
; Does not stop script execution for some reason. A value of '0' means 'off '.
; Available units: s (econds) (default), m (inutes), h (ours), or d (ays)
; Default Value: 0
Request_terminate_timeout = 0

Because this parameter will directly kill the php process and restart the php process, the front-end nginx will return 104: Connection reset by peer. This process is very slow. The general feeling is that the website is very slow.

Nginx may have 502
Recv () failed (104: Connection reset by peer) while reading response header from upstream

3. Do not enable the request_slowlog_timeout configuration.

Previously, this parameter was set on the server as follows:

Request_slowlog_timeout = 10 causes image processing to fail at a time, with a 502 error each time.

The error message is as follows:

Nginx error message:
16:20:23 [error] 649 #0: * 9862 recv () failed (104: Connection reset by peer) while reading response header from upstream, client: 163.177.69.13,

The error message for php-fpm is:

Therefore, it is best to disable this setting.
; Request_slowlog_timeout = 10
