2.修改配置文件

# cd
/etc/httpd/conf
# ls
httpd.conf 
magic
#cp httpd.conf httpd.conf.origin    //將原有配置文件備份
# more httpd.conf
//查看配置文件,我們注意到以一配置：
DocumentRoot"/var/www/html"
  
//特別是要注意這個配置
//這是Apache 2.4的一個新的默認值，拒絕所有的請求！
  
<Directory />
   AllowOverride none
    Require all denied
</Directory>
  
//設置為自動啟動
# systemctl enable httpd.service
ln -s'/usr/lib/systemd/system/httpd.service' '/etc/systemd/system/multi-user.target.wants/httpd.service'
//在centos7中chkconfig httpd on 被替換成 systemctl enable httpd

3.配置WEB站點 （假設使用/wwwroot目錄下的文檔）

//創建兩個網站的目錄結構及測試用頁面文件
# mkdir/wwwroot/www
# echo"www.bigcloud.local" > /wwwroot/www/index.html
  
# mkdir/wwwroot/crm
# echo"crm.bigcloud.local" > /wwwroot/crm/index.html
 //配置虛擬機主機
# cd/etc/httpd/
# mkdirvhost-conf.d
# echo"Include vhost-conf.d/*.conf" >> conf/httpd.conf
  
# vi/etc/httpd/vhost-conf.d/vhost-name.conf
//添加如下內容
<VirtualHost *:80>
   ServerNamewww.bigcloud.local
  DocumentRoot /wwwroot/www/
</VirtualHost>
<Directory /wwwroot/www/>
    Requireall granted
</Directory>
  
<VirtualHost *:80>
   ServerNamecrm.bigcloud.local
  DocumentRoot /wwwroot/crm/
</VirtualHost>
<Directory /wwwroot/crm/>
   Require ip192.168.188.0/24   //可以設置訪問限制
</Directory>
