如果你不是安装 Cacti 到 Apache 默认的网络目录文件夹位置，那么在 /etc/httpd/conf.d 中新增配置文件 cacti.conf，并且按如下内容编辑。设置 /your/cacti/dir 为你自己的cacti目录名称。更新 Allow from 127.0.0.1 为任何你需要的的配置（比如，你所在公司的某个子网段）。请留意注释中的配置提示，尤其是在你启用了 SELinux 的时候！
# Cacti - the complete rrdtool-based graphing solution
#
# Allows only localhost by default
#
# Allowing cacti to anyone other than localhost should be considered
# dangerous unless properly secured by SSL
# Make sure, that httpd can read your cacti directories.
# At minimum, you need
# chmod ugo+r -R /your/cacti/dir
# Make sure to replace with your directories
# When using SELinux, set the following:
# chcon -R -h -t httpd_sys_content_t /your/cacti/dir
# when using SELinux and you private homedir, enable
# setsebool -P httpd_enable_homedirs 1
# setsebool -P httpd_read_user_content 1
Alias /cacti /your/cacti
