PHP-FPM 和 Nginx: 502 Bad Gateway

配置

• Ubuntu Server 11.1064位
• Amazon AWS，Ec2，托管在云上
• 微实例

在编写其他内容之前，我想声明，我已经检查了 Nginx 502坏网关和 Nginx + PHP-FPM 502糟糕的网关线程，不幸的是，它们在这方面没有帮助到我。

这个问题似乎相当普遍: nginx 或 php-fpm 的错误配置可能导致 502 Bad Gateway错误，这是我无法摆脱的。请注意，这将显示 甚至当我进入我的域根目录时，而不指定任何特定的目录。

我正在运行一个 AmazonEC2网络服务器，启用了端口9000，打开了端口80，等等。

特别的问题是，我怎样才能摆脱这个讨厌的错误？或者，更好的是，我怎样才能让 php5-fpm到 真的有用。

到目前为止我所做的努力

主要是对配置文件进行一致的编辑，特别是 php-fpm.conf和 nginx.conf。

I. < em > php-fpm. conf

我添加了以下内容，但这些内容并没有多大帮助:

;;;;;;;;;;;;;
; Fpm Start ;
;;;;;;;;;;;;;


;pm.start_servers = 20
;pm.min_spare_servers = 5
;pm.max_spare_servers = 35

现在，我尝试包含我的配置文件:

include=/etc/php5/fpm/*.conf

这只会让我更难过。

完全配置

;;;;;;;;;;;;;;;;;;;;;
; FPM Configuration ;
;;;;;;;;;;;;;;;;;;;;;


; All relative paths in this configuration file are relative to PHP's install
; prefix (/usr). This prefix can be dynamicaly changed by using the
; '-p' argument from the command line.


; Include one or more files. If glob(3) exists, it is used to include a bunch of
; files from a glob(3) pattern. This directive can be used everywhere in the
; file.
; Relative path can also be used. They will be prefixed by:
;  - the global prefix if it's been set (-p arguement)
;  - /usr otherwise
;include=/etc/php5/fpm/*.conf


;;;;;;;;;;;;;;;;;;
; Global Options ;
;;;;;;;;;;;;;;;;;;


[global]
; Pid file
; Note: the default prefix is /var
; Default Value: none
pid = /var/run/php5-fpm.pid


; Error log file
; Note: the default prefix is /var
; Default Value: log/php-fpm.log
error_log = /var/log/php5-fpm.log


; Log level
; Possible Values: alert, error, warning, notice, debug
; Default Value: notice
log_level = notice


; If this number of child processes exit with SIGSEGV or SIGBUS within the time
; interval set by emergency_restart_interval then FPM will restart. A value
; of '0' means 'Off'.
; Default Value: 0
;emergency_restart_threshold = 0


; Interval of time used by emergency_restart_interval to determine when
; a graceful restart will be initiated.  This can be useful to work around
; accidental corruptions in an accelerator's shared memory.
; Available Units: s(econds), m(inutes), h(ours), or d(ays)
; Default Unit: seconds
; Default Value: 0
emergency_restart_interval = 0


; Time limit for child processes to wait for a reaction on signals from master.
; Available units: s(econds), m(inutes), h(ours), or d(ays)
; Default Unit: seconds
; Default Value: 0
;process_control_timeout = 0


; Send FPM to background. Set to 'no' to keep FPM in foreground for debugging.
; Default Value: yes
daemonize = no


;;;;;;;;;;;;;
; Fpm Start ;
;;;;;;;;;;;;;


;pm.start_servers = 20
;pm.min_spare_servers = 5
;pm.max_spare_servers = 35


;;;;;;;;;;;;;;;;;;;;
; Pool Definitions ;
;;;;;;;;;;;;;;;;;;;;


; Multiple pools of child processes may be started with different listening
; ports and different management options.  The name of the pool will be
; used in logs and stats. There is no limitation on the number of pools which
; FPM can handle. Your system will tell you anyway :)


; To configure the pools it is recommended to have one .conf file per
; pool in the following directory:
include=/etc/php5/fpm/pool.d/*.conf

Ii . < em > nginx.conf

老实说，这个配置只是我访问过的少数几个网站中的一小部分，但是我可以告诉你，在这个502 Bad Gateway 业务之前，服务器运行良好(没有 PHP 工作)。句号).

问题主要在于事实上有些事情是非常非常错误的。现在，当我尝试做一个 service php5-fpm restart，它挂在什么，我猜是一个无限循环或东西，我甚至不能 CTRL-C出来。
