先是安装完cacti；用http://ip:port/cacti/index.php测试，正常；
然后继续安装nagios；安装完后用
http://ip:port/nagios测试，正常；
然后，继续跳会cacti的时候，竟然报错了：

=========================
返回去就不行了；
之前编译安装过一次这2个；这次想简便些；
我修改了：
# vi /etc
添加了allow from all
然后
service httpd restart
3、配置
Apache
说明：默认cacti目录只允许本机127.0.0.1访问，如果不设置将会出现You don't have permission to access /cacti/ on this server.
vi /etc/httpd/conf.d/cacti.conf
Alias /cacti /usr/share/cacti
<Directory /usr/share/cacti/>
Order Deny,Allow
Deny from all
Allow from 127.0.0.1
Allow from 192.168.1.88
</Directory>
