nginx如何配置虚拟主机

server
    {
        listen 80;
        #listen [::]:80 default_server ipv6only=on;
        server_name local.presion.caomall.net;
        index index.html index.htm index.php;
        root  /home/wwwroot/default/precision/Public;  

        #error_page   404   /404.html;
        include enable-php-pathinfo.conf;  //注意这里从  nginx.conf 复制过来，如果不修改这里，主入口文件不支持require

        location /nginx_status
        {
            stub_status on;
            access_log   off;
        }  

        location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
        {
            expires      30d;
        }  

        location ~ .*\.(js|css)?$
        {
            expires      12h;
        }  

        location ~ /\.
        {
            deny all;
        }  

        access_log  /home/wwwlogs/access.log;
    }
