1.相关配置文件目录：
Apache的配置文件：httpd.conf，位于：/etc/httpd/conf/httpd.conf，配置文件中包含 Include conf.d/*.conf ，引入了 /etc/httpd/conf.d/ 文件夹下的所有配置文件。
2.修改配置文件：/etc/httpd/conf.d/elastix.conf，禁用重定位地址到 https ：
原文：
<Directory "/var/www/html">
# Redirect administration interface to https
RewriteEngine on
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}
</Directory>
修改为：
<Directory "/var/www/html">
# Redirect administration interface to https
RewriteEngine off
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}
</Directory>
3.重命名配置文件：/etc/httpd/conf.d/elastix.conf，不再包含引入 ssl 配置文件：
[/etc/httpd/conf.d]# mv ssl.conf ssl.conf1
4.重启 Apache：
httpd -k restart
