配置虛擬主機(jī)，接受 Host 首部與 *.dddxxx.com 匹配的請(qǐng)求。

判斷 HTTP 請(qǐng)求的 HOST 首部，如果不是 dddxxx.com 或者 www.dddxxx.com，則進(jìn)行重定向到 dddxxx.com

通過設(shè)置變量到達(dá)條件組合的效果。

server {
    listen 80;
    server_name dddxxx.com www.dddxxx.com *.dddxxx.com;
    root /var/www/html/dddxxx.com;
    access_log /var/log/nginx/dddxxx.com.access_log.log;

    set $myhost '';

    if ($host = 'dddxxx.com') {
        set $myhost 1;
    }

    if ($host = 'www.dddxxx.com') {
        set $myhost 1;
    }

    if ($myhost != 1) {
            rewrite ^/(.*)$ http://dddxxx.com/$1 permanent;
    }

    location / {
        try_files $uri $uri/ =404;
