一、php-fpm测试配置及平滑重启方法

#测试php-fpm配置

/usr/local/php/sbin/php-fpm -t

/usr/local/php/sbin/php-fpm -c  /usr/local/php/etc/php.ini –y  /usr/local/php/etc/php-fpm.conf -t


#启动php-fpm

/usr/local/php/sbin/php-fpm

/usr/local/php/sbin/php-fpm -c  /usr/local/php/etc/php.ini  -y  /usr/local/php/etc/php-fpm.conf


#关闭php-fpm

kill -INT `cat /usr/local/php/var/run/php-fpm.pid`


#重启php-fpm

kill -USR2 `cat  /usr/local/php/var/run/php-fpm.pid`


或者通过将安装包中的initd.php-fpm文件复制到/etc/init.d/目录下并授权,可直接进行操作.

/etc/init.d/php-fpm start|stop|restart



二、php-fpm.conf配置文件详解

   目前没有对文中的所有文字进行完整的翻译,如果有人需要很详尽的翻译,可以自己翻译下,此处只做简单的说明。


;;;;;;;;;;;;;;;;;;;;;

; FPM Configuration ;

;;;;;;;;;;;;;;;;;;;;;


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

; prefix (/usr/local/webserver/php). This  prefix can be dynamicaly changed by using the

; '-p' argument from the command line.

;说明此配置文件的路径前缀为php安装路径


; 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/local/webserver/php otherwise

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




;;;;;;;;;;;;;;;;;;

; Global Options ;

;全局配置

;;;;;;;;;;;;;;;;;;


[global]

; Pid file

; Note: the default prefix is  /usr/local/webserver/php/var

;Default Value: on

pid = run/php-fpm.pid

;pid文件默认在php/var/run/下面

;slowlog = log/slow.log

;慢日志文件,默认是没有指定的。可以进行开启。


; Error log file

; If it's set to "syslog", log  is sent to syslogd instead of being written

; in a local file.

; Note: the default prefix is  /usr/local/webserver/php/var

; Default Value: log/php-fpm.log

error_log = log/php-fpm.log

;错误日志文件默认页是在php/var/log下面的。


; 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  daemonequiv 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

;如果有多个php-fpm那么可以设置在syslog中的标识


; Log level

; Possible Values: alert, error, warning,  notice, debug

; Default Value: notice

;定义记录日志级别,默认是notice级别

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

;如果达到了设定的时间和数量其余的php-fpm子进程就会被关系,设置为0表示关闭。

;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

; 表示在emergency_restart_interval所设值内出现SIGSEGV或者SIGBUS错误的php-cgi进程数如果超过  emergency_restart_threshold个,php-fpm就会优雅重启。这两个选项一般保持默认值。但笔者设置为60 60s

;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

#设置子进程接受主进程复用信号的超时时间.  可用单位: s(), m(), h(小时), 或者 d() 默认单位: s(). 默认值: 0.



; The maximum number of  processes FPM will fork. This has been design 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

;当进程数设置为动态的时候,控制进程的最大数,使用此参数要谨慎。

; 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 (lower 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 it 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

;php-fpm在后台进行执行,设置为no表示在前台执行,默认是yes#后台执行fpm,默认值为yes,如果为了调试可以改为no。在FPM中,可以使用不同的设置来运行多个进程池。这些设置可以针对每个进程池单独设置。


; Set open file descriptor rlimit for the  master process.

; Default Value: system defined value

;rlimit_files = 1024

;设置能够打开的最大文件数,默认是系统设置的限制数量,但是最好还是自己设置。


; 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)

; - port       (Solaris >= 10)

; Default Value: not set (auto detection)

; events.mechanism = epoll


;;;;;;;;;;;;;;;;;;;;

; Pool Definitions ;

;池设置

;;;;;;;;;;;;;;;;;;;;


; 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 :)

;可以设置多个pool池,pool池管理不同的子进程资源


; 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)

;pool池名称

[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/local/webserver/php) 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.

; 启动进程的账户和组

user = www

group = www


; 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.

; fpm监听端口,即nginxphp处理的地址,一般默认值即可。可用格式为: 'ip:port', 'port', '/path/to/unix/socket'. 每个进程池都需要设置。

listen = 127.0.0.1:9000


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

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

; #backlog数,-1表示无限制,由操作系统决定,此行注释掉就行。

;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 = nobody

;listen.group = nobody

;listen.mode = 0666

;unix socket设置选项,如果使用tcp方式访问,这里注释即可。


; 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

;允许访问FastCGI进程的IP,设置any为不限制IP,如果要设置其他主机的nginx也能访问这台FPM进程,listen处要设置成本地可被访问的IP。默认值是any。每个地址是用逗号分隔. 如果没有设置或者为空,则允许任何服务器请求连接


; Specify the nice(2) priority to apply  to the pool processes (only if set)

; The value can vary from -19 (highest  priority) to 20 (lower priority)

; Note: - It will only work if the FPM  master process is launched as root

;        - The pool processes will  inherit the master process priority

;          unless it specified otherwise

; Default Value: no set

; priority = -19


; 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

;pm = dynamic #对于专用服务器,pm可以设置为static

;如何控制子进程,选项有staticdynamic。如果选择static,则由pm.max_children指定固;定的子进程数。如果选择dynamic,则由下开参数决定:

;pm.max_children #子进程最大数

;pm.start_servers #启动时的进程数

;pm.min_spare_servers #,保证空闲进程数最小值,如果空闲进程小于此值,则创建新的子进程

;pm.max_spare_servers #,保证空闲进程数最大值,如果空闲进程大于此值,此进行清理


; 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 = 150


; 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

; 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 = 5


; 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'

;设置系统空闲进程,保证系统能够接收.

pm.max_spare_servers = 35


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

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

; Default Value: 10s

;设置进程空闲几秒之后被关闭

;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

; 设置每个子进程重生之前服务的请求数. 对于可能存在内存泄漏的第三方模块来说是非常有用的. 如果设置为 '0' 则一直接受请求. 等同于 PHP_FCGI_MAX_REQUESTS 环境变量. 默认值: 0.

pm.max_requests = 65535


;设置可以监控php-cgi状态.

; 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;

;    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

;

; 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

;    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:

;    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;

;    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

; 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

; exectutephp code.

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

; Default Value: .php

;    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.
