配置Apache及Nginx实现Yii框架的URL美化

1. Apache

Yii已经做好了默认以Apache服务器运行的配置部署。Yii框架和应用文件夹中的.htaccess?文件严格控制受限制资源的访问， 如果想要在URL中隐藏入口脚本 (通常是?index.php)，可以在应用根目录下的.htaccess文件中添加?mod_rewrite?功能，或者配置虚拟主机来实现URL的美化:

RewriteEngine on

# prevent httpd from serving dotfiles (.htaccess, .svn, .git, etc.)
RedirectMatch 403 /\..*$
# if a directory or a file exists, use it directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# otherwise forward it to index.php
RewriteRule . index.php

2.Nginx

这里是一个简单的Nginx配置示例，里面定义了启动文件并且使得yii可以获取所有不存在的文件请求，从而实现URL的美化。

server {
    set $host_path "/www/mysite";
    access_log  /www/mysite/log/access.log  main;

    server_name  mysite;
    root   $host_path/htdocs;
    set $yii_bootstrap "index.php";

    charset utf-8;

    location / {
        index  index.html $yii_bootstrap;
        try_files $uri $uri/ /$yii_bootstrap?$args;
    }

    location ~ ^/(protected|framework|themes/\w+/views) {
        deny  all;
    }

    #avoid processing of calls to unexisting static files by yii
    location ~ \.(js|css|png|jpg|gif|swf|ico|pdf|mov|fla|zip|rar)$ {
        try_files $uri =404;
    }

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    location ~ \.php {
        fastcgi_split_path_info  ^(.+\.php)(.*)$;

        #let yii catch the calls to unexising PHP files
        set $fsn /$yii_bootstrap;
        if (-f $document_root$fastcgi_script_name){
            set $fsn $fastcgi_script_name;
        }

        fastcgi_pass   127.0.0.1:9000;
        include fastcgi_params;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fsn;

        #PATH_INFO and PATH_TRANSLATED can be omitted, but RFC 3875 specifies them for CGI
        fastcgi_param  PATH_INFO        $fastcgi_path_info;
        fastcgi_param  PATH_TRANSLATED  $document_root$fsn;
    }

    # prevent nginx from serving dotfiles (.htaccess, .svn, .git, etc.)
    location ~ /\. {
        deny all;
        access_log off;
        log_not_found off;
    }
}

使用这个配置你可以在php.ini设置?cgi.fix_pathinfo=0?来避免许多不必要的系统stat() 调用.
