会话文件每 2 秒创建一次。在 openshift Laravel PHP nginx haproxy 上运行

Question

服务器启动时访问服务器的原因是什么？

我已经rhc tail在我的应用程序上运行以监控新日志。

这是我的日志 http://laravel.io/bin/Dez4o

当我开始使用应用程序时 rhc app-start

然后我尝试访问我的网站根目录

(my.sever.ip.address) - - [26/Jul/2016:21:53:24 -0400]  200 "GET /login HTTP/1.1" 1422 "-" "Mozilla/5.0 (Windows NT 6.2; Win64; x64; rv:47.0) Gecko/20100101 Firefox/47.0" "(my.client.ip.address)"

... other assets

但日志在加载后继续

(my.sever.ip.address) - - [26/Jul/2016:21:53:33 -0400]  302 "GET / HTTP/1.0" 364 "-" "-" "-"

然后我执行了rhc app-stop停止服务器

这些是执行“停止”后的日志

app-root/logs/php-fpm-error.log

[26-Jul-2016 21:53:55] NOTICE: Terminating ...

这 access logs

Answer 1

所描述的行为与 haproxy 的 http 健康检查相匹配。创建新会话是因为 haproxy 不会在健康检查之间保留 cookie，因此您的应用程序 (Laravel) 将请求视为新浏览会话的第一个请求。

您可以将您的健康检查 url 重新配置为不使用会话的内容，以避免创建会话文件，但这意味着即使会话功能被破坏，健康检查也会通过。

“inter”参数将两次连续健康检查之间的间隔设置为毫秒。如果未指定，延迟默认为 2000 毫秒。
