安装php成功后要重启 Apache，否则 php脚本不被解释当成纯文本

nginx php-fpm安装配置 – 运维与架构 - nginx.cn http://www.nginx.cn/231.html

nginx本身不能处理PHP，它只是个web服务器，当接收到请求后，如果是php请求，则发给php解释器处理，并把结果返回给客户端。

nginx一般是把请求发fastcgi管理进程处理，fascgi管理进程选择cgi子进程处理结果并返回被nginx

本文以php-fpm为例介绍如何使nginx支持PHP

一、编译安装php-fpm

什么是PHP-FPM

PHP-FPM是一个PHP FastCGI管理器，是只用于PHP的,可以在 http://php-fpm.org/download下载得到.

PHP-FPM其实是PHP源代码的一个补丁，旨在将FastCGI进程管理整合进PHP包中。必须将它patch到你的PHP源代码中，在编译安装PHP后才可以使用。

新版PHP已经集成php-fpm了，不再是第三方的包了，推荐使用。PHP-FPM提供了更好的PHP进程管理方式，可以有效控制内存和进程、可以平滑重载PHP配置，比spawn-fcgi具有更多优点，所以被PHP官方收录了。在./configure的时候带 –enable-fpm参数即可开启PHP-FPM，其它参数都是配置php的，具体选项含义可以查看这里。

PHP: FastCGI 进程管理器（FPM） - Manual http://php.net/manual/zh/install.fpm.php

FastCGI 进程管理器（FPM）

FPM（FastCGI 进程管理器）用于替换 PHP FastCGI 的大部分附加功能，对于高负载网站是非常有用的。

它的功能包括：

支持平滑停止/启动的高级进程管理功能；
可以工作于不同的 uid/gid/chroot 环境下，并监听不同的端口和使用不同的 php.ini 配置文件（可取代 safe_mode 的设置）；
stdout 和 stderr 日志记录;
在发生意外情况的时候能够重新启动并缓存被破坏的 opcode;
文件上传优化支持;
"慢日志" - 记录脚本（不仅记录文件名，还记录 PHP backtrace 信息，可以使用 ptrace或者类似工具读取和分析远程进程的运行数据）运行所导致的异常缓慢;
fastcgi_finish_request() - 特殊功能：用于在请求完成和刷新数据后，继续在后台执行耗时的工作（录入视频转换、统计处理等）；
动态／静态子进程产生；
基本 SAPI 运行状态信息（类似Apache的 mod_status）；
基于 php.ini 的配置文件。

PHP: FastCGI Process Manager (FPM) - Manual http://php.net/manual/en/install.fpm.php

FPM (FastCGI Process Manager) is an alternative PHP FastCGI implementation with some additional features (mostly) useful for heavy-loaded sites.

These features include:

advanced process management with graceful stop/start;
ability to start workers with different uid/gid/chroot/environment, listening on different ports and using different php.ini (replaces safe_mode);
stdout and stderr logging;
emergency restart in case of accidental opcode cache destruction;
accelerated upload support;
"slowlog" - logging scripts (not just their names, but their PHP backtraces too, using ptrace and similar things to read remote process' execute_data) that are executed unusually slow;
fastcgi_finish_request() - special function to finish request and flush all data while continuing to do something time-consuming (video converting, stats processing etc.);
dynamic/static child spawning;
basic SAPI status info (similar to Apache mod_status);
php.ini-based config file.

安装

从源代码编译

编译 PHP 时需要 --enable-fpm 配置选项来激活 FPM 支持。

以下为 FPM 编译的具体配置参数（全部为可选参数）：

--with-fpm-user - 设置 FPM 运行的用户身份（默认 - nobody）
--with-fpm-group - 设置 FPM 运行时的用户组（默认 - nobody）
--with-fpm-systemd - 启用 systemd 集成 (默认 - no)
--with-fpm-acl - 使用POSIX 访问控制列表 (默认 - no) 5.6.5版本起有效

Installation

Compiling from sources

In order to enable FPM in your PHP build you need to add --enable-fpm to your configure line.

There are several other FPM-specific configure options (all of them optional):

--with-fpm-user - set FPM user (default - nobody).
--with-fpm-group - set FPM group (default - nobody).
--with-fpm-systemd - Activate systemd integration (default - no).
--with-fpm-acl - Use POSIX Access Control Lists (default - no). Since PHP 5.6.5.

配置

FPM 使用类似 php.ini 语法的 php-fpm.conf 和进程池配置文件。

`php-fpm.conf` 全局配置段

pid string: PID 文件的位置。默认为空。
error_log string: 错误日志的位置。默认：#INSTALL_PREFIX#/log/php-fpm.log。如果设置为 "syslog"，日志将不会写入本地文件，而是发送到 syslogd。
log_level string: 错误级别。可用级别为：alert（必须立即处理），error（错误情况），warning（警告情况），notice（一般重要信息），debug（调试信息）。默认：notice。
syslog.facility string: 设置何种程序记录消息，默认值：daemon。
syslog.ident string: 为每条信息添加前缀。如果在同一台服务器上运行了多个 FPM 实例，可以修改此默认值来满足需求。默认值：php-fpm。
emergency_restart_threshold int: 如果子进程在 emergency_restart_interval 设定的时间内收到该参数设定次数的 SIGSEGV 或者 SIGBUS退出信息号，则FPM会重新启动。0 表示“关闭该功能”。默认值：0（关闭）。
emergency_restart_interval mixed: emergency_restart_interval 用于设定平滑重启的间隔时间。这么做有助于解决加速器中共享内存的使用问题。可用单位：s（秒），m（分），h（小时）或者 d（天）。默认单位：s（秒）。默认值：0（关闭）。
process_control_timeout mixed: 设置子进程接受主进程复用信号的超时时间。可用单位：s（秒），m（分），h（小时）或者 d（天）。默认单位：s（秒）。默认值：0（关闭）。
process.max int: Fork 的最大 FPM 进程数。使用动态管理进程数时，此设计可以控制在一个进程池内的全局进程数量。使用需谨慎。默认值：0。
process.priority int: 设置 master 进程的 nice(2) 优先级（如果设置了此值）。可以是 -19（最高优先级）到 20 （更低优先级）。默认值：不设置。
daemonize boolean: 设置 FPM 在后台运行。设置“no”将 FPM 保持在前台运行用于调试。默认值：yes。
rlimit_files int: 设置 master 进程的打开文件描述符 rlimit 数。
rlimit_core int: 设置 master 进程最大 core 的 rlimit 尺寸。默认值：0。
events.mechanism string: 设置 FPM 使用的事件机制。可用以下选项：select、pool、epoll、kqueue (*BSD)、port (Solaris)。默认值：不设置（自动检测）
systemd_interval int: 使用 systemd 集成的 FPM 时，设置间歇秒数，报告健在通知给 systemd。设置为 0 表示禁用。默认值：10。

运行配置区段

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。

listen string

设置接受 FastCGI 请求的地址。可用格式为：'ip:port'，'port'，'/path/to/unix/socket'。每个进程池都需要设置。

listen.backlog int

设置 listen(2) 的 backlog 最大值。“-1”表示无限制。默认值：-1。

listen.allowed_clients string

设置允许连接到 FastCGI 的服务器 IPV4 地址。等同于 PHP FastCGI (5.2.2+) 中的 FCGI_WEB_SERVER_ADDRS 环境变量。仅对 TCP 监听起作用。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。默认值：any。 PHP 5.5.20 和 5.6.4起，开始支持 IPv6 地址。

listen.owner string

如果使用了 Unix 套接字，表示它的权限。在 Linux 中必须设置读/写权限，以便用于 WEB 服务器连接。在很多 BSD 派生的系统中可以忽略权限允许自由连接。默认值：运行所使用的用户和组，权限为 0660。

listen.group string

参见 listen.owner。

listen.mode string

参见 listen.owner。

listen.acl_users string

当系统支持 POSIX ACL（Access Control Lists）时，可以设置使用此选项。当设置了的时候，将会忽略 listen.owner 和 listen.group。值是逗号分割的用户名列表。 PHP 5.6.5 起可用。

listen.acl_groups string

参见 listen.acl_users。值是逗号分割的用户组名称列表。 PHP 5.6.5 起可用。

user string

FPM 进程运行的Unix用户。必须设置。

group string

FPM 进程运行的 Unix 用户组。如果不设置，就使用默认用户的用户组。

pm string

设置进程管理器如何管理子进程。可用值：static，ondemand，dynamic。必须设置。

static - 子进程的数量是固定的（pm.max_children）。

ondemand - 进程在有需求时才产生（当请求时才启动。与 dynamic 相反，在服务启动时 pm.start_servers 就启动了。

dynamic - 子进程的数量在下面配置的基础上动态设置：pm.max_children，pm.start_servers，pm.min_spare_servers，pm.max_spare_servers。

pm.max_children int

pm 设置为 static 时表示创建的子进程的数量，pm 设置为 dynamic 时表示最大可创建的子进程的数量。必须设置。

该选项设置可以同时提供服务的请求数限制。类似 Apache 的 mpm_prefork 中 MaxClients 的设置和普通PHP FastCGI中的 PHP_FCGI_CHILDREN 环境变量。

pm.start_servers in

设置启动时创建的子进程数目。仅在 pm 设置为 dynamic 时使用。默认值：min_spare_servers + (max_spare_servers - min_spare_servers) / 2。

pm.min_spare_servers int

设置空闲服务进程的最低数目。仅在 pm 设置为 dynamic 时使用。必须设置。

pm.max_spare_servers int

设置空闲服务进程的最大数目。仅在 pm 设置为 dynamic 时使用。必须设置。

pm.process_idle_timeout mixed

秒数，多久之后结束空闲进程。仅当设置 pm 为 ondemand。可用单位：s（秒），m（分），h（小时）或者 d（天）。默认单位：10s。

pm.max_requests int

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.status_path string

FPM 状态页面的网址。如果没有设置，则无法访问状态页面，默认值：无。

ping.path string

FPM 监控页面的 ping 网址。如果没有设置，则无法访问 ping 页面。该页面用于外部检测 FPM 是否存活并且可以响应请求。请注意必须以斜线开头（/）。

ping.response string

用于定义 ping 请求的返回响应。返回为 HTTP 200 的 text/plain 格式文本。默认值：pong。

process.priority int

设置 worker 的 nice(2)优先级（如果设置了的话）。该值从 -19（最高优先级）到 20（更低优先级）。默认值：不设置

prefix string

检测路径时使用的前缀。

request_terminate_timeout mixed

设置单个请求的超时中止时间。该选项可能会对 php.ini 设置中的 'max_execution_time' 因为某些特殊原因没有中止运行的脚本有用。设置为 '0' 表示 'Off'。可用单位：s（秒），m（分），h（小时）或者 d（天）。默认单位：s（秒）。默认值：0（关闭）。

request_slowlog_timeout mixed

当一个请求该设置的超时时间后，就会将对应的 PHP 调用堆栈信息完整写入到慢日志中。设置为 '0' 表示 'Off'。可用单位：s（秒），m（分），h（小时）或者 d（天）。默认单位：s（秒）。默认值：0（关闭）。

slowlog string

慢请求的记录日志。默认值：#INSTALL_PREFIX#/log/php-fpm.log.slow。

rlimit_files int

设置文件打开描述符的 rlimit 限制。默认值：系统定义值。

rlimit_core int

设置核心 rlimit 最大限制值。可用值：'unlimited'，0 或者正整数。默认值：系统定义值。

chroot string

启动时的 Chroot 目录。所定义的目录需要是绝对路径。如果没有设置，则 chroot 不被使用。

chdir string

设置启动目录，启动时会自动 Chdir 到该目录。所定义的目录需要是绝对路径。默认值：当前目录，或者根目录（chroot时）。

catch_workers_output boolean

重定向运行过程中的 stdout 和 stderr 到主要的错误日志文件中。如果没有设置，stdout 和 stderr 将会根据 FastCGI 的规则被重定向到 /dev/null。默认值：无。

clear_env boolean

为 FPM worker 进程清除环境变量。在进程池配置文件里设置环境变量前，阻止任意系统的环境变量进入 FPM worker 进程。自 PHP 5.4.27、 5.5.11 和 5.6.0 起。默认值: Yes

security.limit_extensions string

限制 FPM 允许解析的脚本扩展名。此设置可以预防 web 服务器配置的错误。应当限制 FPM 仅仅解析 .php 扩展名，阻止恶意用户使用其他扩展名运行 php 代码。默认值： .php .phar

access.log string

Access log 文件。默认值：不设置

access.format string

access log 的格式。默认值: "%R - %u %t \"%m %r\" %s"

还可以在为一个运行池传递附加的环境变量，或者更新 PHP 的配置值。可以在进程池配置文件中如下面的配置参数来做到：

Example #1 给运行池传递环境变量和设置 PHP 的配置值

env[HOSTNAME] = $HOSTNAME
       env[PATH] = /usr/local/bin:/usr/bin:/bin
       env[TMP] = /tmp
       env[TMPDIR] = /tmp
       env[TEMP] = /tmp

       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

PHP配置值通过 php_value 或者 php_flag 设置，并且会覆盖以前的值。请注意 disable_functions 或者disable_classes 在 php.ini 之中定义的值不会被覆盖掉，但是会将新的设置附加在原有值的后面。

使用 php_admin_value 或者 php_admin_flag 定义的值，不能被 PHP 代码中的 ini_set() 覆盖。

自 5.3.3 起，也可以通过 web 服务器设置 PHP 的设定。

Example #2 在 nginx.conf 中设定 PHP

set $php_value "pcre.backtrack_limit=424242";
set $php_value "$php_value \n pcre.recursion_limit=99999";
fastcgi_param  PHP_VALUE $php_value;

fastcgi_param  PHP_ADMIN_VALUE "open_basedir=/var/www/htdocs";

Caution

由于这些设定是以 FastCGI 标头传递给 php-fpm，php-fpm 不应绑定到外部网可以访问的地址上，否则任何人都能修改 PHP 的配置选项了。参见 listen.allowed_clients。

FPM uses php.ini syntax for its configuration file - php-fpm.conf, and pool configuration files.

List of global `php-fpm.conf` directives

pid string: Path to PID file. Default value: none.
error_log string: Path to error log file. Default value: #INSTALL_PREFIX#/log/php-fpm.log. If it's set to "syslog", log is sent to syslogd instead of being written in a local file.
log_level string: Error log level. Possible values: alert, error, warning, notice, debug. Default value: notice.
syslog.facility string: used to specify what type of program is logging the message. Default value: daemon.
syslog.ident string: 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.
emergency_restart_threshold int: 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 (Off).
emergency_restart_interval mixed: 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 (Off).
process_control_timeout mixed: 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.max int: 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. Default value: 0.
process.priority int: 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). Default value: not set.
daemonize boolean: Send FPM to background. Set to 'no' to keep FPM in foreground for debugging. Default value: yes.
rlimit_files int: Set open file descriptor rlimit for the master process. Default value: Set open file descriptor rlimit for the master process.
rlimit_core int: Set max core size rlimit for the master process. Default value: 0.
events.mechanism string: Specify the event mechanism FPM will use. The following is available: select, pool, epoll, kqueue (*BSD), port (Solaris). Default value: not set (auto detection).
systemd_interval int: When FPM is build with systemd integration, specify the interval, in second, between health report notification to systemd. Set to 0 to disable. Default value: 10.

List of pool directives

With FPM you can run several pools of processes with different setting. These are settings that can be tweaked per pool.

listen string

The address on which to accept FastCGI requests. Valid syntaxes are: 'ip.add.re.ss:port', 'port', '/path/to/unix/socket'. This option is mandatory for each pool.

listen.backlog int

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

listen.allowed_clients string

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 FastCGI (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. IPv6 addresses are allowed since PHP 5.5.20 and 5.6.4.

listen.owner string

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 0660.

listen.group string

See listen.owner.

listen.mode string

See listen.owner.

listen.acl_users string

When POSIX Access Control Lists are supported you can set them using this option. When set, listen.owner and listen.group are ignored. Value is a comma separated list of user names. Since PHP 5.6.5.

listen.acl_groups string

See listen.acl_users. Value is a comma separated list of group names. Since PHP 5.6.5.

user string

Unix user of FPM processes. This option is mandatory.

group string

Unix group of FPM processes. If not set, the default user's group is used.

pm string

Choose how the process manager will control the number of child processes. Possible values: static, ondemand, dynamic. This option is mandatory.

static - the number of child processes is fixed (pm.max_children).

ondemand - the processes spawn on demand (when requested, as opposed to dynamic, where pm.start_servers are started when the service is started.

dynamic - the number of child processes is set dynamically based on the following directives: pm.max_children, pm.start_servers, pm.min_spare_servers, pm.max_spare_servers.

pm.max_children int

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 option is mandatory.

This option sets the limit on the number of simultaneous requests that will be served. Equivalent to the ApacheMaxClients directive with mpm_prefork and to the PHP_FCGI_CHILDREN environment variable in the original PHP FastCGI.

pm.start_servers int

The number of child processes created on startup. Used only when pm is set to dynamic. Default Value: min_spare_servers + (max_spare_servers - min_spare_servers) / 2.

pm.min_spare_servers int

The desired minimum number of idle server processes. Used only when pm is set to dynamic. Also mandatory in this case.

pm.max_spare_servers int

The desired maximum number of idle server processes. Used only when pm is set to dynamic. Also mandatory in this case.

pm.process_idle_timeout mixed

The number of seconds after which an idle process will be killed. Used only when pm is set to ondemand. Available units: s(econds)(default), m(inutes), h(ours), or d(ays). Default value: 10s.

pm.max_requests int

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 toPHP_FCGI_MAX_REQUESTS. Default value: 0.

pm.status_path string

The URI to view the FPM status page. If this value is not set, no URI will be recognized as a status page. Default value: none.

ping.path string

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. Please note that the value must start with a leading slash (/).

ping.response string

This directive may be used to customize the response to a ping request. The response is formatted as text/plain with a 200 response code. Default value: pong.

process.priority int

Specify the nice(2) priority to apply to the worker process (only if set). The value can vary from -19 (highest priority) to 20 (lower priority). Default value: not set.

process.dumpable boolean

Set the process dumpable flag (PR_SET_DUMPABLE prctl) even if the process user or group is different than the master process user. It allows to create process core dump and ptrace the process for the pool user. Default Value: no. Since PHP 7.0.29, 7.1.17 and 7.2.5.

prefix string

Specify prefix for path evaluation

request_terminate_timeout mixed

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_slowlog_timeout mixed

The timeout for serving a single request after which a PHP backtrace will be dumped to the 'slowlog' file. A value of '0' means 'Off'. Available units: s(econds)(default), m(inutes), h(ours), or d(ays). Default value: 0.

slowlog string

The log file for slow requests. Default value: #INSTALL_PREFIX#/log/php-fpm.log.slow.

rlimit_files int

Set open file descriptor rlimit for child processes in this pool. Default value: system defined value.

rlimit_core int

Set max core size rlimit for child processes in this pool. Possible Values: 'unlimited' or an integer greater or equal to 0. Default value: system defined value.

chroot string

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.

chdir string

Chdir to this directory at the start. This value must be an absolute path. Default value: current directory or / when chroot.

catch_workers_output boolean

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.

clear_env boolean

Clear environment in FPM workers. Prevents arbitrary environment variables from reaching FPM worker processes by clearing the environment in workers before env vars specified in this pool configuration are added. Since PHP 5.4.27, 5.5.11, and 5.6.0. Default value: Yes.

security.limit_extensions string

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 execute php code. Default value: .php .phar

access.log string

The access log file. Default value: not set

access.format string

The access log format. Default value: "%R - %u %t \"%m %r\" %s"

It's possible to pass additional environment variables and update PHP settings of a certain pool. To do this, you need to add the following options to the pool configuration file.

Example #1 Passing environment variables and PHP settings to a pool

env[HOSTNAME] = $HOSTNAME
env[PATH] = /usr/local/bin:/usr/bin:/bin
env[TMP] = /tmp
env[TMPDIR] = /tmp
env[TEMP] = /tmp

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

PHP settings passed with php_value or php_flag will overwrite their previous value. Please note that definingdisable_functions or disable_classes will not overwrite previously defined php.ini values, but will append the new value instead.

Settings defined with php_admin_value and php_admin_flag cannot be overriden with ini_set().

As of 5.3.3, PHP settings are also possible to be set in webserver.

Example #2 set PHP settings in nginx.conf

set $php_value "pcre.backtrack_limit=424242";
set $php_value "$php_value \n pcre.recursion_limit=99999";
fastcgi_param  PHP_VALUE $php_value;

fastcgi_param  PHP_ADMIN_VALUE "open_basedir=/var/www/htdocs";

Caution

Because these settings are passed to php-fpm as fastcgi headers, php-fpm should not be bound to a worldwide accessible address. Otherwise, anyone could alter the PHP configuration options. See alsolisten.allowed_clients.

What is PHP-FPM?

PHP-FPM (FastCGI Process Manager) is an alternative PHP FastCGI implementation with some additional features useful for sites of any size, especially busier sites.

These features include:

Adaptive process spawning (NEW!)
Basic statistics (ala Apache's mod_status) (NEW!)
Advanced process management with graceful stop/start
Ability to start workers with different uid/gid/chroot/environment and different php.ini (replaces safe_mode)
Stdout & stderr logging
Emergency restart in case of accidental opcode cache destruction
Accelerated upload support
Support for a "slowlog"
Enhancements to FastCGI, such as fastcgi_finish_request() - a special function to finish request & flush all data while continuing to do something time-consuming (video converting, stats processing, etc.)

... and much more.

It was not designed with virtual hosting in mind (large amounts of pools) however it can be adapted for any usage model.
