基于Nginx的Wordpress安装失败?

鄙人新手，最近手上有个服务器就想搭个简单博客自己暗爽一下。于是选择最简单的wordpress，按照wordpress上的教程一步步安装，同时安装mysql分配了wordpress的数据库，然后按照资料安装用yum安装了php*（我把php所有的包都装了，包括php-fpm）,服务器我选择的Nginx，也是用yum 安装的。

但是通过install.php继续安装wordpress却出现404错误，去掉nginx默认配置的部分注释之后出现500错误

感觉是nginx的设置问题，但是在CentOS中配置文件的地方和网上的不一样，而且网上各种资料的配置也不一样，求老鸟解惑，菜鸟不尽感激。

/etc/nginx/nginx.conf内容如下：

user  nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    include /etc/nginx/conf.d/*.conf;
}

/etc/nginx/conf.d/default.conf设置如下：

server {
    listen       80;
    server_name  localhost;

    #charset koi8-r;
    #access_log  /var/log/nginx/log/host.access.log  main;

    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }

    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    location ~ \.php$ {
        proxy_pass   http://127.0.0.1;
    }

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    location ~ \.php$ {
        root           html;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
        include        fastcgi_params;
    }

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    location ~ /\.ht {
        deny  all;
    }
}

/etc/nginx/fastcgi_params设置如下:

fastcgi_param  QUERY_STRING       $query_string;
fastcgi_param  REQUEST_METHOD     $request_method;
fastcgi_param  CONTENT_TYPE       $content_type;
fastcgi_param  CONTENT_LENGTH     $content_length;

fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
fastcgi_param  REQUEST_URI        $request_uri;
fastcgi_param  DOCUMENT_URI       $document_uri;
fastcgi_param  DOCUMENT_ROOT      $document_root;
fastcgi_param  SERVER_PROTOCOL    $server_protocol;
fastcgi_param  HTTPS              $https if_not_empty;

fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    nginx/$nginx_version;

fastcgi_param  REMOTE_ADDR        $remote_addr;
fastcgi_param  REMOTE_PORT        $remote_port;
fastcgi_param  SERVER_ADDR        $server_addr;
fastcgi_param  SERVER_PORT        $server_port;
fastcgi_param  SERVER_NAME        $server_name;

# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param  REDIRECT_STATUS    200;

将 nginx 的 default 配置修改为：

fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock

root xxx;

location / {
       index index.php;
}

location ~ \.php5?($|/) {
       set $script $uri;
       set $path_info "";

       if ($uri ~ "^(.+\.php)(/.+)") {
             set $script $1;
             set $path_info $2;
       }

       unix:/var/run/php-fpm/php-fpm.sock
       fastcgi_index index.php;
       fastcgi_param SCRIPT_FILENAME $document_root$script;
       fastcgi_param SCRIPT_NAME $script;
       fastcgi_param PATH_INFO $path_info;
}

...
