1. 查看到/www/server/php/55/var/log/php-fpm.log

[07-Nov-2018 10:14:24] WARNING: [pool www] seems busy (you may need to increase pm.start_servers, or pm.min/max_spare_servers), spawning 8 children, there are 0 idle, and 273 total children
[07-Nov-2018 10:14:25] WARNING: [pool www] seems busy (you may need to increase pm.start_servers, or pm.min/max_spare_servers), spawning 16 children, there are 0 idle, and 281 total children
[07-Nov-2018 10:14:26] WARNING: [pool www] seems busy (you may need to increase pm.start_servers, or pm.min/max_spare_servers), spawning 32 children, there are 7 idle, and 297 total children

修改php-fpm.log中对应参数

[global]
pid = /www/server/php/55/var/run/php-fpm.pid
error_log = /www/server/php/55/var/log/php-fpm.log
log_level = notice

[www]
listen = /tmp/php-cgi-55.sock
listen.backlog = 4096
listen.allowed_clients = 127.0.0.1
listen.owner = www
listen.group = www
listen.mode = 0666
user = www
group = www
pm = dynamic
pm.status_path = /phpfpm_55_status
pm.max_children = 600
pm.start_servers = 30
pm.min_spare_servers = 30
pm.max_spare_servers = 200
request_terminate_timeout = 0
request_slowlog_timeout = 30
slowlog = var/log/slow.log

2.查看慢日志对代码针对性优化 。查看到/www/server/php/55/var/log/slow.log

我这最后是由于sql 索引进行优化

script_filename = /www/wwwroot/tui/upload/u.php
[0x00007f4473e26070] mysql_connect() /www/wwwroot/tui/common/db/dbMysql.php:68
