Доброго дня. В один день вдруг началась такая проблема. При осуществление действий от имени авторизованного пользователя (выставление статей на сайт) появляется ошибка 502. Не всегда, через раз. После каких именно действий она появляется, так и не смог выяснить. После чего такое произошло тоже. Ниже конфиги nginx.cfg

Было keepalive_timeout 600; Сделал 1000, ошибка при публикации материалов стала появлятся крайне редко, но теперь вылезет при просмотре сайта у всех пользователей, опять же иногда, бывает при клике на фото, бывает при просмотре материала.

Какие логи и конфигу нужно, скину. Куда копать? уже сума сойду скоро.

php-fpm.conf

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

; All relative paths in this configuration file are relative to PHP's install
; prefix (/usr/lib/php5.3). 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/lib/php5.3 otherwise
;include=/etc/php/fpm-php5.3/fpm.d/*.conf

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

[global]
; Pid file
; Note: the default prefix is /var/lib
; Default Value: none
; Warning: pid file is overriden by the Gentoo init script.
; FPM will refuse to start if you uncomment this settingi and make use of the
; init script. 
; pid = /var/run/php-fpm.pid

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

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

; 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 = 1m

; 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 = 5s

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

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

; Start a new pool named 'www'.
; the variable $pool can we used in any directive and will be replaced by the
; pool name ('www' here)
[www]

; Per pool prefix
; It only applies on the following directives:
; - 'slowlog'
; - 'listen' (unixsocket)
; - 'chroot'
; - 'chdir'
; - 'php_values'
; - 'php_admin_values'
; When not set, the global prefix (or /usr/lib/php5.3) applies instead.
; Note: This directive can also be relative to the global prefix.
; Default Value: none
;prefix = /path/to/pools/$pool

; The address on which to accept FastCGI requests.
; Valid syntaxes are:
;   'ip.add.re.ss:port'    - to listen on a TCP socket to a specific address on
;                            a specific port;
;   'port'                 - to listen on a TCP socket to all addresses on a
;                            specific port;
;   '/path/to/unix/socket' - to listen on a unix socket.
; Note: This value is mandatory.
;listen = 127.0.0.1:9000
listen = /var/run/php5-fpm.sock

; Set listen(2) backlog. A value of '-1' means unlimited.
; Default Value: 128 (-1 on FreeBSD and OpenBSD)
listen.backlog = 4096
 
; List of ipv4 addresses of FastCGI clients which are allowed to connect.
; Equivalent to the FCGI_WEB_SERVER_ADDRS environment variable in the original
; PHP FCGI (5.2.2+). Makes sense only with a tcp listening socket. Each address
; must be separated by a comma. If this value is left blank, connections will be
; accepted from any ip address.
; Default Value: any
;listen.allowed_clients = 127.0.0.1

; Set permissions for unix socket, if one is used. In Linux, read/write
; permissions must be set in order to allow connections from a web server. Many
; BSD-derived systems allow connections regardless of permissions. 
; Default Values: user and group are set as the running user
;                 mode is set to 0666
listen.owner = nobody
listen.group = nobody
listen.mode = 0666

; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default user's group
;       will be used.
user = nobody
group = nobody

; Choose how the process manager will control the number of child processes.
; Possible Values:
;   static  - a fixed number (pm.max_children) of child processes;
;   dynamic - the number of child processes are set dynamically based on the
;             following directives:
;             pm.max_children      - the maximum number of children that can
;                                    be alive at the same time.
;             pm.start_servers     - the number of children created on startup.
;             pm.min_spare_servers - the minimum number of children in 'idle'
;                                    state (waiting to process). If the number
;                                    of 'idle' processes is less than this
;                                    number then some children will be created.
;             pm.max_spare_servers - the maximum number of children in 'idle'
;                                    state (waiting to process). If the number
;                                    of 'idle' processes is greater than this
;                                    number then some children will be killed.
; Note: This value is mandatory.
;pm = static
pm = dynamic

; The number of child processes to be created when pm is set to 'static' and the
; maximum number of child processes to be created when pm is set to 'dynamic'.
; This value sets the limit on the number of simultaneous requests that will be
; served. Equivalent to the ApacheMaxClients directive with mpm_prefork.
; Equivalent to the PHP_FCGI_CHILDREN environment variable in the original PHP
; CGI.
; Note: Used when pm is set to either 'static' or 'dynamic'
; Note: This value is mandatory.
;pm.max_children = 16
pm.max_children = 128

; 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 = 32

; 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 = 8

; 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 = 32
 
; The number of requests each child process should execute before respawning.
; This can be useful to work around memory leaks in 3rd party libraries. For
; endless request processing specify '0'. Equivalent to PHP_FCGI_MAX_REQUESTS.
; Default Value: 0
pm.max_requests = 500

; The URI to view the FPM status page. If this value is not set, no URI will be
; recognized as a status page. By default, the status page shows the following
; information:
;   accepted conn        - the number of request accepted by the pool;
;   pool                 - the name of the pool;
;   process manager      - static or dynamic;
;   idle processes       - the number of idle processes;
;   active processes     - the number of active processes;
;   total processes      - the number of idle + active processes.
;   max children reached - number of times, the process limit has been reached,
;                          when pm tries to start more children (works only for
;                          pm 'dynamic')
; The values of 'idle processes', 'active processes' and 'total processes' are
; updated each second. The value of 'accepted conn' is updated in real time.
; Example output:
;   accepted conn:        12073
;   pool:                 www
;   process manager:      static
;   idle processes:       35
;   active processes:     65
;   total processes:      100
;   max children reached: 1
; By default the status page output is formatted as text/plain. Passing either
; 'html' or 'json' as a query string will return the corresponding output
; syntax. Example:
;   http://www.foo.bar/status
;   http://www.foo.bar/status?json
;   http://www.foo.bar/status?html
; Note: The value must start with a leading slash (/). The value can be
;       anything, but it may not be a good idea to use the .php extension or it
;       may conflict with a real PHP file.
; Default Value: not set 
pm.status_path = /statusphpfpmbysergeyfortest.php
 
; The ping URI to call the monitoring page of FPM. If this value is not set, no
; URI will be recognized as a ping page. This could be used to test from outside
; that FPM is alive and responding, or to
; - create a graph of FPM availability (rrd or such);
; - remove a server from a group if it is not responding (load balancing);
; - trigger alerts for the operating team (24/7).
; Note: The value must start with a leading slash (/). The value can be
;       anything, but it may not be a good idea to use the .php extension or it
;       may conflict with a real PHP file.
; Default Value: not set
;ping.path = /ping
ping.path = /pingphpfpmbysergeyfortest.php

; This directive may be used to customize the response of a ping request. The
; response is formatted as text/plain with a 200 response code.
; Default Value: pong
;ping.response = pong
 
; The timeout for serving a single request after which the worker process will
; be killed. This option should be used when the 'max_execution_time' ini option
; does not stop script execution for some reason. A value of '0' means 'off'.
; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
; Default Value: 0
;request_terminate_timeout = 0
 
; The timeout for serving a single request after which a PHP backtrace will be
; dumped to the 'slowlog' file. A value of '0s' means 'off'.
; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
; Default Value: 0
;request_slowlog_timeout = 0
 
; The log file for slow requests
; Default Value: not set
; Note: slowlog is mandatory if request_slowlog_timeout is set
;slowlog = /var/log/php-fpm-$pool.log.slow
 
; Set open file descriptor rlimit.
; Default Value: system defined value
rlimit_files = 65535
 
; Set max core size rlimit.
; Possible Values: 'unlimited' or an integer greater or equal to 0

502 Bad Gateway
The server, while acting as a gateway or proxy, received an invalid response from the upstream server it accessed in attempting to fulfill the request.

Проксирующий сервер получил неподходящий ответ в процессе удовлетворения клиента.

104: Connection reset by peer

Скорее всего скрипт по таймауту сброшен был.

Вываливай конфиг и еррорлог пыхи.
Не пытайся увеличивать таймаут пыхи больше нескольких секунд, это не решение. Надо найти тормозючий скрипт и прибиль.

Нет тут ничего удобного для кода.
Вставляй как есть или ссылкой на пасты.
Конфиг надо тот, который пыха использует.

Но таки важнее для начала посмотреть на еррорлог пыхи, ибо ошибка в 502 это про неё.

На другом форуме посоветовали подумать о взломе. Заметил в логах php-fmp.log вот такое

[error] 24183#0: *59622995 connect() failed (111: Connection refused) while connecting to upstream, client: 66.249.78.129 (последние две цифры адреса «78.129"меняются), server: mysite.ru, request: „GET /medik/UserFiles/Flash/seks/porno-dvuh.html HTTP/1.1“, upstream: »http://ip моего сервера:80/medik/UserFiles/Flash/seks/porno-dvuh.html", host: «mysite.ru» Таких файлов на сервере нет, точно.

Может залочить доступ адресу 66.249.*.* есть ли такая возможность вообще? (сервер мой, доступ полный)

MrFakir ()
Ответ на: комментарий от MrFakir

Нет, надо не доступ лочить, а разбираться кто и зачем туда ходит. Включи логирование конкретного скрипта и номера строчки кода и посмотри что там в нём происходит. Ну и трассировку для таких запросов в лог тоже может стоит выводить.

К тому же на 66.249 у него явно не получается, но это не значит что нет других адресов этой дряни, на которые успех.
Лечить надо причину, а не симптомы.

Насколько я понимаю нужно было ошибки которые появляются в одно и то-же время. Во время 502 ошибки, nginx логирует 104: Connection... то что в это время в логах php представляю выше.

Вот тут я вообще ничего не понял.

«Включи логирование конкретного скрипта и номера строчки кода» Как? Какого?

«Ну и трассировку для таких запросов в лог тоже может стоит выводить.» Просто слова известные, а смысл не понятен.

В этом месте объяснений для «нуба» не найдётся? или хотябы что гуглить.

Надо было ERROR, а не DEBUG или NOTICE.
104: Connection reset by peer — это явно ошибка, а не нормальное поведение.
И это не упавший/свалившийся процесс, это именно возврат ошибки.

что гуглить

php-fpm verbose error log
Я сам пыху уже очень давно не готовил, почти всё позабыл.
Наверняка у тебя получится не хуже меня найти как там включить логирование нормальное.
Надо чтобы оно выводило место возникновения ошибки в скрипте и желательно текущие значения переменных скрипта.

Google Inc

Это пока ни о чём не говорит.
Для начала стоит выяснить что и почему туда ломится.
Может это так и надо.
А может и не надо.

А не может быть такого, что у тебя на сервере есть какой-то скрипт, который периодически рестартует php-fpm и из-за этого у тебя вылазит 502?
