我正在尝试使用Nginx php-fpm与nginx选项'keepalive'和'fastcgi_keep_conn on'来保持tcp连接在它们之间保持活动状态，但在服务几百个请求后面临错误 "104: Connection reset by peer" .

在tcp端口(9000)或unix socket(/var/run/php5-fpm.socket)上启动php-fpm可以看到这些错误 .

这里的内容是尽可能减少Nginx php-fpm之间的新tcp / socket连接开销，并尽可能地重用连接 . 请注意，我保持nginx'keepalive 20'，其中php-fpm'pm.max_requests = 0'和'pm.start_servers = 50' .

有人可以帮我解决这个错误吗？

使用的软件：

nginx version: nginx/1.4.7

php-fpm version: 5.4.25 / 5.6.6

PHP-FPM错误日志条目：

WARNING: [pool www] child 15388 exited on signal 15 (SIGTERM) after 2245.557110 seconds from start

NOTICE: [pool www] child 18701 started

Nginx错误：

用php-fpm监听端口 9000

[error] 32310#0: *765 readv() failed (104: Connection reset by peer) while reading upstream, client: 10.10.133.xx, server: 192.168.28.xxx, request: "GET /test.php HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "10.10.133.xxx"

用php-fpm监听套接字 /var/run/php5-fpm.socket

[error] 14894#0: *383 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 10.10.133.xx, server: 192.168.28.xxx, request: "GET /test.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.socket:", host: "10.10.133.xxx"

以下是nginx vhost conf

upstream fastcgi_backend {

}

server {

fastcgi_keep_conn on; #Test for keepalive connection to php-fpm

}

以下是php-fpm.conf
