本节包括在 Unix 平台的 Lighttpd 1.4 下安装 PHP 的说明和提示。
推荐阅读 » Lighttpd trac 了解一下正确安装 Lighttpd 然后继续。
推荐使用 Fastcgi 作为 SAPI 模块来连接 PHP 和 Lighttpd。在 PHP 5.3 中自动激活了 Fastcgi,对于旧版本则在配置时使用 --enable-fastcgi。要确认 PHP 已激活 Fastcgi 可以使用命令 php -v,应该显示 PHP 5.2.5 (cgi-fcgi)。在 PHP 5.2.3 之前,Fastcgi 是包含在 php 可执行文件中(没有 php-cgi 文件)。
要配置 Lighttpd 连接到 php 并产生 fastcgi 进程,编辑 lighttpd.conf。推荐使用套接字在本机连接 fastcgi 进程。
Example #1 Partial lighttpd.conf
server.modules += ( "mod_fastcgi" )fastcgi.server = ( ".php" => (( "socket" => "/tmp/php.socket", "bin-path" => "/usr/local/bin/php-cgi", "bin-environment" => ( "PHP_FCGI_CHILDREN" => "16", "PHP_FCGI_MAX_REQUESTS" => "10000" ), "min-procs" => 1, "max-procs" => 1, "idle-timeout" => 20 )) )
bin-path 指令允许 lighttpd 动态产生 fastcgi 进程。PHP 会根据 PHP_FCGI_CHILDREN 环境变量产生子进程。“bin-environment”指令设定了所产生的进行的环境。PHP 会在达到 PHP_FCGI_MAX_REQUESTS 所指定的请求数目之后杀死一个子进程。在 PHP 中通常应避免“min-procs”和“max-procs”指令。PHP 自己管理其子进程,并且例如 APC 之类的 opcode 缓存仅在 PHP 管理下的子进程之间共享。如果“min-procs”被设定成某个大于 1 的值,则 PHP 应答器的总数目为该值乘以 PHP_FCGI_CHILDREN(如 min-procs 为 2,PHP_FCGI_CHILDREN 为 16 则会产生 32 个应答器)。
Lighttpd 提供一个名为 spawn-fcgi 的程序来简化产生 fastcgi 进程的手续。
有可能不通过 spawn-fcgi 来产生进程,但需要做些工作。设定 PHP_FCGI_CHILDREN 环境变量控制了 PHP 产生多少个子进程来处理请求。设定 PHP_FCGI_MAX_REQUESTS 将决定每个子进程存活多久(以请求数目决定)。以下为一个简单的 bash 脚本来帮助产生 php 应答器。
Example #2 产生 FastCGI 应答器
#!/bin/sh# Location of the php-cgi binary PHP=/usr/local/bin/php-cgi# PID File location PHP_PID=/tmp/php.pid# Binding to an address #FCGI_BIND_ADDRESS=10.0.1.1:10000 # Binding to a domain socket FCGI_BIND_ADDRESS=/tmp/php.sockPHP_FCGI_CHILDREN=16 PHP_FCGI_MAX_REQUESTS=10000env -i PHP_FCGI_CHILDREN=$PHP_FCGI_CHILDREN \ PHP_FCGI_MAX_REQUESTS=$PHP_FCGI_MAX_REQUESTS \ $PHP -b $FCGI_BIND_ADDRESS &echo $! > "$PHP_PID"
Fastcgi 实例可被产生于多个远程机器以分散应用程序。
Example #3 连接远程 php-fastcgi 实例
fastcgi.server = ( ".php" => (( "host" => "10.0.0.2", "port" => 1030 ), ( "host" => "10.0.0.3", "port" => 1030 )) )

You can custom php.ini just add environment PHPRC in your virtualhost.
fastcgi.server = ( ".php" => ((
"bin-path" => "/usr/bin/php-cgi",
"socket" => "/tmp/php.socket",
"bin-environment" => (
"PHP_FCGI_CHILDREN" => "3",
"PHP_FCGI_MAX_REQUESTS" => "1000",
"PHPRC" => "/usr/www/vhost1/php.ini"
),
"bin-copy-environment" => (
"PATH", "SHELL", "USER"
),
"broken-scriptfilename" => "enable"
)))

If PHP_FCGI_MAX_REQUESTS isn't given, the default value is 500.
