Zbyt wysokie zapotrzebowanie CPU php-fpm (100%)

[Graffiter. 6]

Cześć, mam problem. Gdy przytrzyma się dłużej klawisz F5 na forum, php-fpm pobiera 100% zapotrzebowania CPU. Korzystam z PHP-FPM + Nginx.

Config www.conf php-fpm:

 

 

; 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) applies instead.

; Note: This directive can also be relative to the global prefix.

; Default Value: none

;prefix = /path/to/pools/$pool

; 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 = www-data

group = www-data

; 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 = /tmp/php5-fpm.sock

; Set listen(2) backlog. A value of '-1' means unlimited.

; Default Value: 128 (-1 on FreeBSD and OpenBSD)

;listen.backlog = -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 = www-data

;listen.group = www-data

;listen.mode = 0666

; 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

; 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. With this process management, there will be

; always at least 1 children.

; 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.

; ondemand - no children are created at startup. Children will be forked when

; new requests will connect. The following parameter are used:

; pm.max_children - the maximum number of children that

; can be alive at the same time.

; pm.process_idle_timeout - The number of seconds after which

; an idle process will be killed.

; Note: This value is mandatory.

pm = static

; The number of child processes to be created when pm is set to 'static' and the

; maximum number of child processes when pm is set to 'dynamic' or 'ondemand'.

; 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. The below defaults are based on a server without much resources. Don't

; forget to tweak pm.* to fit your needs.

; Note: Used when pm is set to 'static', 'dynamic' or 'ondemand'

; Note: This value is mandatory.

pm.max_children = 10

; 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 = 1

; 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 = 2

; 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 = 6

; The number of seconds after which an idle process will be killed.

; Note: Used only when pm is set to 'ondemand'

; Default Value: 10s

pm.process_idle_timeout = 10s;

; 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 = 200

; The URI to view the FPM status page. If this value is not set, no URI will be

; recognized as a status page. It shows the following informations:

; pool - the name of the pool;

; process manager - static, dynamic or ondemand;

; start time - the date and time FPM has started;

; start since - number of seconds since FPM has started;

; accepted conn - the number of request accepted by the pool;

; listen queue - the number of request in the queue of pending

; connections (see backlog in listen(2));

; max listen queue - the maximum number of requests in the queue

; of pending connections since FPM has started;

; listen queue len - the size of the socket queue of pending connections;

; idle processes - the number of idle processes;

; active processes - the number of active processes;

; total processes - the number of idle + active processes;

; max active processes - the maximum number of active processes since FPM

; has started;

; max children reached - number of times, the process limit has been reached,

; when pm tries to start more children (works only for

; pm 'dynamic' and 'ondemand');

; Value are updated in real time.

; Example output:

; pool: www

; process manager: static

; start time: 01/Jul/2011:17:53:49 +0200

; start since: 62636

; accepted conn: 190460

; listen queue: 0

; max listen queue: 1

; listen queue len: 42

; idle processes: 4

; active processes: 11

; total processes: 15

; max active processes: 12

; max children reached: 0

;

; By default the status page output is formatted as text/plain. Passing either

; 'html', 'xml' or 'json' in the 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

; http://www.foo.bar/status?xml

;

; By default the status page only outputs short status. Passing 'full' in the

; query string will also return status for each pool process.

; Example:

; http://www.foo.bar/status?full

; http://www.foo.bar/status?json&full

; http://www.foo.bar/status?html&full

; http://www.foo.bar/status?xml&full

; The Full status returns for each process:

; pid - the PID of the process;

; state - the state of the process (Idle, Running, ...);

; start time - the date and time the process has started;

; start since - the number of seconds since the process has started;

; requests - the number of requests the process has served;

; request duration - the duration in µs of the requests;

; request method - the request method (GET, POST, ...);

; request URI - the request URI with the query string;

; content length - the content length of the request (only with POST);

; user - the user (PHP_AUTH_USER) (or '-' if not set);

; script - the main script called (or '-' if not set);

; last request cpu - the %cpu the last request consumed

; it's always 0 if the process is not in Idle state

; because CPU calculation is done when the request

; processing has terminated;

; last request memory - the max amount of memory the last request consumed

; it's always 0 if the process is not in Idle state

; because memory calculation is done when the request

; processing has terminated;

; If the process is in Idle state, then informations are related to the

; last request the process has served. Otherwise informations are related to

; the current request being served.

; Example output:

; ************************

; pid: 31330

; state: Running

; start time: 01/Jul/2011:17:53:49 +0200

; start since: 63087

; requests: 12808

; request duration: 1250261

; request method: GET

; request URI: /test_mem.php?N=10000

; content length: 0

; user: -

; script: /home/fat/web/docs/php/test_mem.php

; last request cpu: 0.00

; last request memory: 0

;

; Note: There is a real-time FPM status monitoring sample web page available

; It's available in: ${prefix}/share/fpm/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 access log file

; Default: not set

;access.log = log/$pool.access.log

; The access log format.

; The following syntax is allowed

; %%: the '%' character

; %C: %CPU used by the request

; it can accept the following format:

; - %{user}C for user CPU only

; - %{system}C for system CPU only

; - %{total}C for user + system CPU (default)

; it can accept the following format:

; - %{seconds}d (default)

; - %{miliseconds}d

; - %{mili}d

; - %{microseconds}d

; - %{micro}d

; %e: an environment variable (same as $_ENV or $_SERVER)

; it must be associated with embraces to specify the name of the env

; variable. Some exemples:

; - server specifics like: %{REQUEST_METHOD}e or %{SERVER_PROTOCOL}e

; - HTTP headers like: %{HTTP_HOST}e or %{HTTP_USER_AGENT}e

; %f: script filename

; %l: content-length of the request (for POST request only)

; %m: request method

; %M: peak of memory allocated by PHP

; it can accept the following format:

; - %{bytes}M (default)

; - %{kilobytes}M

; - %{kilo}M

; - %{megabytes}M

; - %{mega}M

; %n: pool name

; %o: ouput header

; it must be associated with embraces to specify the name of the header:

; - %{Content-Type}o

; - %{X-Powered-By}o

; - %{Transfert-Encoding}o

; - ....

; %p: PID of the child that serviced the request

; %P: PID of the parent of the child that serviced the request

; %r: the request URI (without the query string, see %q and %Q)

; %R: remote IP address

; %s: status (response code)

; %t: server time the request was received

; it can accept a strftime(3) format:

; %d/%b/%Y:%H:%M:%S %z (default)

; %T: time the log has been written (the request has finished)

; it can accept a strftime(3) format:

; %d/%b/%Y:%H:%M:%S %z (default)

; %u: remote user

;

; Default: "%R - %u %t \"%m %r\" %s"

;access.format = %R - %u %t "%m %r%Q%q" %s %f %{mili}d %{kilo}M %C%%

; The log file for slow requests

; Default Value: not set

; Note: slowlog is mandatory if request_slowlog_timeout is set

;slowlog = log/$pool.log.slow

; 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 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

; Set open file descriptor rlimit.

; Default Value: system defined value

;rlimit_files = 1024

; 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: you can prefix with '$prefix' to chroot to the pool prefix or one

; of its subdirectories. If the pool prefix is not set, the global prefix

; will be used instead.

; 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.

; Note: relative path can be used.

; Default Value: current directory or / when chroot

chdir = /

; 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.

; Note: on highloaded environement, this can cause some delay in the page

; process time (several ms).

; Default Value: no

;catch_workers_output = yes

; Limits the extensions of the main script FPM will allow to parse. This can

; prevent configuration mistakes on the web server side. You should only limit

; FPM to .php extensions to prevent malicious users to use other extensions to

; exectute php code.

; Note: set an empty value to allow all extensions.

; Default Value: .php

;security.limit_extensions = .php .php3 .php4 .php5

; Pass environment variables like LD_LIBRARY_PATH. All $VARIABLEs are taken from

; the current environment.

; Default Value: clean env

;env[HOSTNAME] = $HOSTNAME

;env[PATH] = /usr/local/bin:/usr/bin:/bin

;env[TMP] = /tmp

;env[TMPDIR] = /tmp

;env[TEMP] = /tmp

; 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.

; Note: path INI options can be relative and will be expanded with the prefix

; (pool, global or /usr)

; 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@my.domain.com

;php_flag[display_errors] = off

;php_admin_value[error_log] = /var/log/fpm-php.www.log

;php_admin_flag[log_errors] = on

;php_admin_value[memory_limit] = 32M

No co ty nie powiesz, naprawdę?

Nie, na niby Raczej tak nie powinno być, prawda? Chyba że się mylę.
