CloudFoundry php buildpack 性能调优

采用了开源的cf-php-buildpack。 地址 https://github.com/dmikusa-pivotal/cf-php-build-pack 搭建内部apache 服务器后，将需要的依赖包放入apacher服务器，然后将buildpack中的option.json修改为搭建的apache服务器地址 问题1： 命令行 使用buildpack push

问题1：

命令行 使用buildpack push 后，总是启动失败，查看crashlogs，发现fpm进程 没有启动

Reading logs/stdout.log... OK
06:51:32 php-fpm | /bin/sh: /home/vcap/app/php/sbin/php-fpm: not found
06:51:32 php-fpm-logs | tail: cannot open `/home/vcap/app/../logs/php-fpm.log' for reading: No such file or directory

使用 命令 cf files app/.bp/logs/bp.log 发现根本就没有下载 fpm 依赖包，最后定位出，是因为我的apache 服务器中没有 sha1 文件，增加后，恢复正常

问题2 ：

使用了wordpress 作为测试程序，push成功后，使用apache自带的ab进行测试，发现 10000个请求，500并发只能响应成功不到1000个。。。。。

查看warden内 container 的日志 出现错误：

[16-May-2014 07:16:34] WARNING: [pool www] server reached pm.max_children setting (5), consider raising it

通过调整 buildpack中的php-fpm.conf 文件中的参数

pm.max_children = 30

; The number of child processes created on startup.
; Note: Used only when pm is set to 'dynamic'
; Default Value: min_spare_servers + (max_spare_servers - min_spare_servers) / 2
pm.start_servers =

; The desired minimum number of idle server processes.
; Note: Used only when pm is set to 'dynamic'
; Note: Mandatory when pm is set to 'dynamic'
pm.min_spare_servers = 5

; The desired maximum number of idle server processes.
; Note: Used only when pm is set to 'dynamic'
; Note: Mandatory when pm is set to 'dynamic'
pm.max_spare_servers = 10

最后测试，10000个请求，500并发，可以全部请求成功。
