ubuntu VPS nginx (1.4.6) prohibits other domain names from accessing your server

ubuntu VPS nginx (1.4.6) Forbid other domain names to access

the nginx configuration file under your server ubuntu,

modify its configuration in etc/nginx/sites-ava/default.
If you want to prohibit IP access, you only need to add your server name.

The following code removes the comment # part

server {

        listen 80;
        [b]server_name www.test.com www.test2.com; [/b]
        listen [::]:80 default_server ipv6only=on;
        root /usr/share/nginx/html/3dvr;
        index index.php index.html index.htm;
        location / {

                try_files $uri $uri/ =404;
        }

        location ~ \.php$ {
                fastcgi_split_path_info ^(.+\.php)(/.+)$;
                fastcgi_pass unix:/var/run/php5-fpm.sock;
                fastcgi_index index.php;
                include fastcgi_params;
}

如果需要绑定更多域名，可以添加域名列表，放在配置文件夹下，但是文件要以.conf后缀名。即上层目录的nginx.conf下，然后在default文件中include进来就可以了
像这样

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

三、不带www的域名加301跳转
若不带 www 的域名需加 301 跳转，则先绑定不带 www 的域名，且无需写网站目录，直接进行 301 跳转，如：

server
{
listen 80;
server_name server110.com;
rewrite ^/(.*) http://www.server110.com/$1 permanent;
}

四、添加404网页
添加 404 网页，可以直接在配置中添加，如：

server  
{  
listen             80;  
server_name  www.server110.com;                          #绑定域名  
index index.htm index.html index.php;   #默认文件  
root /home/www/server110.com;                     #网站根目录
include location.conf;                         #调用其他规则，也可去除
error_page 404   /404.html;  
}
