Apache：$ vim /etc/httpd/conf/httpd.conf# 增加下行，避免启动httpd服务出现关于ServerName的警告。ServerName 自定义:80
$ vim /etc/httpd/conf.d/cacti.conf    # 原配置文件内容如下：    #    <Directory /usr/share/cacti/>        <IfModule mod_authz_core.c>                # httpd 2.4                Require host localhost        </IfModule>        <IfModule !mod_authz_core.c>                # httpd 2.2                Order deny,allow                Deny from all                Allow from all        </IfModule>    </Directory>    #    # yum安装的httpd为2.2版本，在httpd-2.2配置段的"Allow from localhost"后添加允许访问的主机IP,    # 或者直接改为"Allow from all"以允许所有IP访问。    # 这样才能进行Cacti的Web端安装和监控。$ /etc/init.d/httpd restart
