4.Virtual Host (網站代管)


(1)建立目錄
#mkdir -p /var/www/html/virt1
#mkdir -p /var/www/html/virt2
並在virt1, virt2裡建立index.html檔案, 當然別忘了SElinux: #restorecon -R /var/www/html

(2)確認DNS是否正確, 增加DNS的A紀錄
[root@server118 ~]# dig virt1.example.com

; <<>> DiG 9.3.4-P1 <<>> virt1.example.com
;; global options: printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 20486
;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 1, ADDITIONAL: 0

;; QUESTION SECTION:

;; ANSWER SECTION:

(3) #vi /etc/httpd/conf/httpd.conf
#vi /etc/httpd/conf/httpd.conf
---略---
NameVirtualHost 192.168.0.118:80

ServerAdmin student@virt1.example.com
DocumentRoot /var/www/html/virt1
ServerName virt1.example.com
ErrorLog logs/virt1.example.com-error_log
CustomLog logs/virt1.example.com-access_log common


ServerAdmin student@virt2.example.com
DocumentRoot /var/www/html/virt2
ServerName virt2.example.com
ErrorLog logs/virt2.example.com-error_log
CustomLog logs/virt2.example.com-access_log common


%也可以寫在/etc/httpd/conf.d/virtual_host.conf (名字自己取）
%這麼多設定那背的起來, 當然找 httpd.conf 複製啦 (keword: NameVirtualHost)
%再來修改設定囉

(4)重新啟動
#service httpd restat

http://virt1.example.com
http://virt2.example.com

%虛擬網站啟動後, http://server118.example.com會被取代，無法看到
%個人網頁putlic_html, http://server118.example.com/student , 也無法看到
%但是http://server118.example.com/~student, 卻可以看到喔
