 80、443端口的等待隊列長度只有128

Recv-Q和Send-Q的含義：

LISTEN 狀態: Recv-Q 表示的當前等待服務端調用 accept 完成三次握手的 listen backlog 數值，也就是說，當客戶端經過 connect() 去鏈接正在 listen() 的服務端時，這些鏈接會一直處於這個 queue 裏面直到被服務端 accept()；Send-Q 表示的則是最大的 listen backlog 數值，這就就是上面提到的 min(backlog, somaxconn) 的值。
其他狀態: 非 LISTEN 狀態以前理解的沒有問題。Recv-Q 表示 receive queue 中的 bytes 數量；Send-Q 表示 send queue 中的 bytes 數值。

• php-fpm.conf參數優化

參考：https://www.kancloud.cn/digest/php-src/136264

[global]
pid = /usr/local/php/var/run/php-fpm.pid
error_log = /usr/local/php/var/log/php-fpm.log
log_level = notice
emergency_restart_threshold = 60
emergency_restart_interval = 60s

[www]
listen = /dev/shm/php-cgi.sock
listen.backlog = 20
listen.allowed_clients = 127.0.0.1
listen.owner = www
listen.group = www
listen.mode = 0666
user = www
group = www
pm = dynamic
pm.max_children = 15
pm.start_servers = 2
pm.min_spare_servers = 2
pm.max_spare_servers = 15
pm.max_requests = 20000
request_slowlog_timeout = 2s
slowlog = var/log/slow.log
pm.status_path = /phpfpm_status

這個是基於內存僅有3G還有其餘java服務，流量並不大的狀況如此配置。單個php-fpm進程消耗內存20M左右。當內存大於8G或者更大的時候pm=static會更好。而且把max_children設置更大。

注意：pm設置爲dynamic的時候當鏈接數超過max_children設置值以後會報server reached pm.max_children setting (10), consider raising it。當pm設置爲static的時候當鏈接數超過max_children設置值以後並不會有報錯。這時候注意觀察pm.status.

listen.backlog = -1表示採用默認值，php7.1.5的默認值128。

backlog太大了，致使FPM處理不過來，nginx那邊等待超時，斷開鏈接，報504 gateway timeout錯。同時FPM處理完準備write 數據給nginx時，發現TCP鏈接斷開了，報「Broken pipe」。backlog過小的話，NGINX之類client，根本進入不了FPM的accept queue，報「502 Bad Gateway」錯。

結論儘可能配置一個合理的數值，具體看業務狀況調節，不要設置成-1

• php7優化
