PHP log error exited with code 0 after seconds from start

Because 502 has occurred before, the log prompt

[27-may-2015 13:54:34] WARNING: [Pool www] seems busy (you could need to increase pm.start_servers, or pm.min/max_spare_servers), spawning Ren, there is all idle, and 602 total children

Then I arbitrarily added the pm.start_servers parameter, after some time, the PHP log/usr/local/php/var/log/php-fpm.log part of the information as follows:


[27-may-2015 15:13:48] NOTICE: [Pool www] child 3998 started

[27-may-2015 15:13:59] NOTICE: [Pool www] child 9242 exited with code 0 after 47575.960999 seconds from start

[27-may-2015 15:13:59] NOTICE: [Pool www] child 4210 started

[27-may-2015 15:14:42] NOTICE: [Pool www] child 9217 exited with code 0 after 47619.884065 seconds from start

[27-may-2015 15:14:42] NOTICE: [Pool www] child 5621 started

[27-may-2015 15:14:43] NOTICE: [Pool www] child 9561 exited with code 0 after 47620.024499 seconds from start


The reason is that there is no pm.start_servers this parameter does not follow the following formula:

pm.start_servers= min_spare_servers + (max_spare_servers-min_spare_servers)/2

General Min_spare_servers set to 20

Max_spare_servers is calculated based on the memory of the server itself, the standard algorithm is the memory size divided by 30M

Of course, some PHP programs may occupy relatively small, less than 30M, which depends on the situation to calculate.

That's what I'm setting up.

Filter the comment section:

cat/usr/local/php/etc/php-fpm.conf | Grep-v "^;" | Grep-v "^$"


[Global]

PID = Run/php-fpm.pid

Error_log = Log/php-fpm.log

Emergency_restart_threshold = 10

Emergency_restart_interval = 1m

Process_control_timeout = 10s

Rlimit_files = 65535

Events.mechanism = Epoll

[WWW]

user = www

Group = www

Listen = 127.0.0.1:9000

PM = dynamic

Pm.max_children = 1400

Pm.start_servers = 710

Pm.min_spare_servers = 20

Pm.max_spare_servers = 1400

Pm.max_requests = 10000

Slowlog = log/$pool. Log.slow


And then reload the next
/usr/local/nginx/sbin/nginx-s Reload

After a few days the log did not appear information.
