Проблема с загрузкой и обработкой файлов
copycat

Ср Окт 27 11:51:55 MSD 2010
Добрый день.
Установлена связка nginx/0.8.53 и php-fpm в
поставке с php 5.3.3.
Все работает хорошо, за исключением
одного момента.
С административной панели одного их
сайтов загружаются графические файлы,
загрузка происходит при помощи флеш
приложения Uplodify, который передает
файлы php скрипту.
1. php получает файл, проверяем по $_FILES
2. функцией imagecopyresampled() кропим 3 раза под
разные размеры и сохраняем файлы
3. пишем в базу
Так вот файлы маленьких размеров
порядка 200-300 К грузятся и
обрабатываются без проблем, файлы
больших размеров 3-9 Мб, грузятся не
всегда, из 5 загружаемых файлов успешно
обрабатываются может 2, может 3, могут
вообще никто. Ранее была связка nginx+apache,
то есть php обрабатывал apache в режиме suexec,
и никаких проблем не было, время
конвертирования изображения
состовляло не более 30 сек. Щас же более
3-х минут. И не всегда понятно почему
одно изображение проходит а некоторе
нет, вероятно это связано с размером
файла, чем больше файл тем больше
времени нужно на обработку. Но
показатели 30 сек. против 3 минут это
порядок в 10 раз.

Далее настройки пула для php-fpm:
;;;;;;;;;;;;;;;;;;;;
; 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'.
[domain.domain.ru]
; 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 = /home/domain/domain.domain.ru.php.sock
; Set listen(2) backlog. A value of '-1' means unlimited.
; Default Value: -1
;listen.backlog = -1
; 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 = arriva
listen.group = apache
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 = arriva
group = arriva
; 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 = dynamic
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 = 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 = 20
; 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 = 15
; 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 = 30
; 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.
; 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
; 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 = /status
; 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
; 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
request_terminate_timeout = 240s
; 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: /var/log/php-fpm.log.slow
;slowlog = /var/log/php-fpm.log.slow
; Set open file descriptor rlimit.
; Default Value: system defined value
rlimit_files = 206103
; Set max core size rlimit.
; Possible Values: 'unlimited' or an integer greater or equal to 0
; Default Value: system defined value
rlimit_core = 0
; Chroot to this directory at the start. This value must be defined as
an
; absolute path. When this value is not set, chroot is not used.
; Note: chrooting is a great security feature and should be used
whenever
; possible. However, all PHP paths will be relative to the chroot
; (error_log, sessions.save_path, ...).
; Default Value: not set
;chroot =
; Chdir to this directory at the start. This value must be an absolute
path.
; Default Value: current directory or / when chroot
;chdir = /var/www
; Redirect worker stdout and stderr into main error log. If not set,
stdout and
; stderr will be redirected to /dev/null according to FastCGI specs.
; Default Value: no
catch_workers_output = yes
; Pass environment variables like LD_LIBRARY_PATH. All are taken from
; the current environment.
; Default Value: clean env
env[HOSTNAME] = domain.ru
env[PATH] = /usr/local/bin:/usr/bin:/bin
env[TMP] = /home/domain/tmp
env[TMPDIR] = /home/domain/tmp
env[TEMP] = /home/domain/tmp
;env[PHP_INI_SCAN_DIR] = /home/domain/php.ini
; Additional php.ini defines, specific to this pool of workers. These
settings
; overwrite the values previously defined in the php.ini. The directives
are the
; same as the PHP SAPI:
; php_value/php_flag - you can set classic ini defines
which can
; be overwritten from PHP call
'ini_set'.
; php_admin_value/php_admin_flag - these directives won't be
overwritten by
; PHP call 'ini_set'
; For php_*flag, valid values are on, off, 1, 0, true, false, yes or
no.
; Defining 'extension' will load the corresponding shared extension
from
; extension_dir. Defining 'disable_functions' or 'disable_classes' will
not
; overwrite previously defined php.ini values, but will append the new
value
; instead.
; Default Value: nothing is defined by default except the values in
php.ini and
; specified at startup with the -d argument
;php_admin_value[sendmail_path] = /usr/sbin/sendmail -t -i -f
www at my.domain.com
