泛域名泛域名證書又名通配符證書是SSL證書中的其中一種形式，一般會以通配符的形式(如：*.domain.com)來指定證書所要保護的域名。OV證書和DV證書都會有通配符的域名形式提供，而EV證書一般沒有通配符的證書形式。1.配置靈活方便由於采用瞭通配符的形式對域名進行配置，那麼對於擁有多個二級域名的網站是一件非常便利的事情。隻要申請一張通配符證書，就能用於所有的二級域名網站中。而且如果以後需要繼續增加二級域名，也不需要再去申請購買證書，隻需繼續使用原有的證書就可以，對於網站管理者來說確實是非常的方便。2.性價比高一般而言，通配符證書是會比單域名證書會貴上不少，但是假如按每個二級域名的證書價格攤分下來，那其實證書單價是及其的低。當然這要看你的二級域名數量總數有多少而定。但如今互聯網時代，很多公司企業他們都會用戶多個二級域名。對於這些企業而言，通配符證書無疑是一種高性價比的SSL證書。安裝所需環境root@cby:~# apt-get install socat -y
