This article mainly explains "what are the precautions for the configuration of / etc/php-fpm.d/www.conf", friends who are interested may wish to take a look. The method introduced in this paper is simple, fast and practical. Next, let the editor take you to learn "what are the precautions in the / etc/php-fpm.d/www.conf configuration"?

1. The value of rlimit_files in the php-fpm configuration file should be the same as the number of open connections of the system.

1) View the number of connections opened by system files

[root@iZ94eveq0q4Z ~] # ulimit-n

65535

2) check the value of rlimit_files 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 not the same, set them to the same

The methods are as follows:

3) set the number of file connections opened by the system

[root@hotdata ~] # ulimit-HSn 65535

[root@hotdata ~] # ulimit-n

65535

[root@hotdata ~] #

Restart the php-fpm service after setting it up

2. Request_terminate_timeout = 0 is set to 0

; The timeout for serving a single request after which the worker process will

; be killed. This option should 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 directly kills the php process, and then restarts the php process, the front-end nginx returns 104: Connection reset by peer. The process is very slow, and the overall feeling is that the website is very slow.

502 may occur in nginx.

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

3. Do not enable this configuration of request_slowlog_timeout

This parameter was started on the server earlier, and is set as follows:

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

The error message is as follows:

Error message for Nginx:

2015-12-28 16:20:23 [error] 6494th: * 9862 recv () failed (9862: Connection reset by peer) while reading response header from upstream, client: 163.177.69.13

The error message for php-fpm is:

So it's best to block this setting.

; request_slowlog_timeout = 10
