我正在嘗試使用 HaProxy 作為我的邊緣網路伺服器，使用 Nginx 作為我在 localhost:9180 上執行的主要應用程序伺服器，正常的代理行為在 domain.com 上執行良好（它只是按預期顯示來自 domain.com 的 :9180 的輸出） , domain.com/subdir/index.php 也是如此 - 但 domain.com/subdir 出於某種原因重定向到 domain.com:9180/subdir - 這是 haproxy 的一些預設行為嗎？我在任何地方都找不到真正描述這種行為的任何東西，這可能是我的 Nginx 配置的一個方面……

可能相關的是，HaProxy 將所有來自 domain.com:443 的流量盲目地傳遞給 Nginx（因此稍後它將傳遞 domain1.com domain2.com domain3.com - 等等），然後由 Nginx 處理域區分和應用程序邏輯每個域的基礎（下面的配置）。我還意識到省略了一些預設配置細節，我仍處於早期階段，所以這在某種程度上是一個原始的概念證明。

HaProxy 配置：

PHP-FPM 配置：

（有人建議它可能是相關的）

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

; All relative paths in this configuration file are relative to PHP's install
; prefix.

; 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.
include=/etc/php-fpm.d/*.conf

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

[global]
; Pid file
; Default Value: none
pid = /run/php-fpm/php-fpm.pid

; Error log file
; If it's set to "syslog", log is sent to syslogd instead of being written
; in a local file.
; Default Value: /var/log/php-fpm.log
error_log = /var/log/php-fpm/error.log

; syslog_facility is used to specify what type of program is logging the
; message. This lets syslogd specify that messages from different facilities
; will be handled differently.
; See syslog(3) for possible values (ex daemon equiv LOG_DAEMON)
; Default Value: daemon
;syslog.facility = daemon

; syslog_ident is prepended to every message. If you have multiple FPM
; instances running on the same server, you can change the default value
; which must suit common needs.
; Default Value: php-fpm
;syslog.ident = php-fpm

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

; Log limit on number of characters in the single line (log entry). If the
; line is over the limit, it is wrapped on multiple lines. The limit is for
; all logged characters including message prefix and suffix if present. However
; the new line character does not count into it as it is present only when
; logging to a file descriptor. It means the new line character is not present
; when logging to syslog.
; Default Value: 1024
;log_limit = 4096

; Log buffering specifies if the log line is buffered which means that the
; line is written in a single write operation. If the value is false, then the
; data is written directly into the file descriptor. It is an experimental
; option that can potentionaly improve logging performance and memory usage
; for some heavy logging scenarios. This option is ignored if logging to syslog
; as it has to be always buffered.
; Default value: yes
;log_buffering = no

; 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

; The maximum number of processes FPM will fork. This has been designed to control
; the global number of processes when using dynamic PM within a lot of pools.
; Use it with caution.
; Note: A value of 0 indicates no limit
; Default Value: 0
;process.max = 128

; Specify the nice(2) priority to apply to the master process (only if set)
; The value can vary from -19 (highest priority) to 20 (lowest priority)
; Note: - It will only work if the FPM master process is launched as root
;       - The pool process will inherit the master process priority
;         unless specified otherwise
; Default Value: no set
;process.priority = -19

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

; Set open file descriptor rlimit for the master process.
; Default Value: system defined value
;rlimit_files = 1024

; Set max core size rlimit for the master process.
; Possible Values: 'unlimited' or an integer greater or equal to 0
; Default Value: system defined value
;rlimit_core = 0

; Specify the event mechanism FPM will use. The following is available:
; - select     (any POSIX os)
; - poll       (any POSIX os)
; - epoll      (linux >= 2.5.44)
; Default Value: not set (auto detection)
;events.mechanism = epoll

; When FPM is built with systemd integration, specify the interval,
; in seconds, between health report notification to systemd.
; Set to 0 to disable.
; Available Units: s(econds), m(inutes), h(ours)
; Default Unit: seconds
; Default value: 10
;systemd_interval = 10

;;;;;;;;;;;;;;;;;;;;
; 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 :)

; See /etc/php-fpm.d/*.conf
