Gentoo 中配置以 FastCGI 方式运行 php

echo "dev-lang/php fpm" >> /etc/portage/package.use
emerge -av dev-lang/php

配置很简单，我本机版本是 php5.4，那么编辑文件 /etc/php/fpm-php5.4/php-fpm.conf，修改 listen address

;listen = 127.0.0.1:9000
listen = /var/run/php-fpm.sock

nginx

打开 fastcgi USE 标记

echo "www-servers/nginx fastcgi" >> /etc/portage/package.use
emerge -av www-servers/nginx

编辑 /etc/nginx/nginx.conf

location ~ .*\.php$ {
    fastcgi_pass   unix:/var/run/php-fpm.sock;
    fastcgi_index  index.php;
    fastcgi_param SCRIPT_FILENAME  $document_root$fastcgi_script_name;
    include        fastcgi_params;
}

lighttpd

打开 php USE 标记

echo "www-servers/lighttpd php" >> /etc/portage/package.use
emerge -av www-servers/lighttpd

编辑 /etc/lighttpd/mod_fastcgi.conf

server.modules += ("mod_fastcgi")
fastcgi.server = ( ".php" =>
    ( "localhost" =>
        (
            "socket"    => "/var/run/php-fpm.sock",
        )
    )
)
fastcgi.map-extensions = ( ".php3" => ".php", ".php4" => ".php", ".php5" => ".php" )

apache

首先需安装 www-apache/mod_fastcgi_handler

emerge -av www-apache/mod_fastcgi_handler

同时 PHP 需要打开 apache2 USE 标记

echo "dev-lang/php apache2" >> /etc/portage/package.use
emerge -av dev-lang/php

编辑文件 /etc/apache2/modules.d/70_mod_php5.conf，告诉 apache2，php-fpm sock 的路径

#    AddHandler application/x-httpd-php .php .php5 .phtml
#    AddHandler application/x-httpd-php-source .phps
    AddHandler fcgi:/var/run/php-fpm.sock .php .php5

编辑文件 /etc/apache2/modules.d/20_mod_fastcgi_handler.conf

LoadModule fastcgi_handler_module modules/mod_fastcgi_handler.so

编辑文件 /etc/conf.d/apache2，在 -D php5 后面添加 -D FASTCGI_HANDLER，告诉 apache2 以 fastcgi-handler 模式启动，类似如下的配置：

APACHE2_OPTS="-D DEFAULT_VHOST -D INFO -D SSL -D SSL_DEFAULT_VHOST -D LANGUAGE -D PHP5 -D FASTCGI_HANDLER"
