php - 如何将 www.example.com/posts/123 转换为 example.com/posts/123？

Question

我正在使用在 Ubuntu 12.10 中运行的 nginx 1.2.1

我遵循了https://stackoverflow.com/a/7958540/80353中的解决方案

所以我的虚拟主机现在看起来像：

server {
        listen 80;
        server_name www.example.com;
        return 301 http://example.com$request_uri;
}
server {
        listen 80;
        client_max_body_size 5M;
        server_name example.com;
        root /var/virtual/example.com/webroot;
        include common.conf;
        include php.conf;
}

不知道我做错了什么。

目前，每当我做 a 时www.example.com/posts/123，我都会得到 302 到example.com

我期待example.com/posts/123

更新：

server {
        listen 80;
        server_name www.example.com;
        rewrite ^(.*) http://example.com$1 permanent;
}
server {
        listen 80;
        client_max_body_size 5M;
        server_name example.com;
        root /var/virtual/example.com/webroot;
        include common.conf;
        include php.conf;
}

common.conf 是：

index index.html;

location ~ /\.ht {
        deny all;
}

cakephp.conf 是：

include php.conf;

location / {
        try_files $uri $uri/ /index.php?$uri&$args;
        expires max;
        access_log off;
}

php.conf 是：

location ~ \.php$ {
        fastcgi_pass 127.0.0.1:9000;
        include fastcgi_params;
}

index index.php;
