服务器上现有一个php网站，可以正常访问，现在要添加一个静态站点，配置好虚拟主机以后无法访问……

nginx.conf配置文件：

user  nginx;
worker_processes  auto;

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


events {
    use     epoll;
    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;

    server_names_hash_bucket_size 128;
    client_header_buffer_size 4k;
    large_client_header_buffers 8 128k;
    open_file_cache max=102400 inactive=20s;
    client_max_body_size 1024m;

    proxy_connect_timeout 90;
    proxy_read_timeout 180;
    proxy_send_timeout 180;
    proxy_buffer_size 256k;
    proxy_buffers 4 256k;
    proxy_busy_buffers_size 256k;
    proxy_temp_file_write_size 256k;
    tcp_nodelay on;
    client_body_buffer_size 512k;
    proxy_intercept_errors on;


    sendfile        on;
    tcp_nopush     on;

    keepalive_timeout  65;

    gzip  on;

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

原先的php项目配置文件：

server {
    listen       80;
    server_name  trmob.com www.trmob.com;
    root /home/www/DynamicWebsite/trmob;
    index index.php default.php index.html index.htm default.html default.htm;
    charset utf-8;
    access_log  /var/log/nginx/log/trmob.access.log  main;

    location ~ .*\.(php|php5)?$ {
        fastcgi_pass  127.0.0.1:9000;
        fastcgi_index index.php;
        include fastcgi_params;
    }
    location /status {
        stub_status on;
        access_log off;
    }
    location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$ {
        expires      30d;
    }
    location ~ .*\.(js|css)?$ {
        expires      1h;
    }
    location ~* ^/(data|templets|uploads|a|images)/.*\.(php|php5)$
    {
        deny all;
    }
}

新的虚拟主机配置：

server {
   listen       80;
   server_name  9longku.com www.9longku.com;
   charset utf-8;
   location / {
      root   /home/www/temp/9longku;
      index  index.html index.htm;
   }
   error_page   500 502 503 504  /50x.html;
   location = /50x.html {
      root   html;
   }
}

ping域名可以ping通，IP地址也对，查看错误日志是这样的：

我用浏览器访问的电脑IP是 117.184.149.210，但是为什么错误日志9、12、13的client 是: 42.156.138.69呢？难道是域名被劫持了？
