需要注意的问题是：在安装完 apache22 后，启动若出现如下提示：（最好在 webmin 中

启动）

““““ FailedFailedFailedFailed totototo enableenableenableenable thethethethe ‘‘‘‘httpreadyhttpreadyhttpreadyhttpready’’’’ AcceptAcceptAcceptAccept FilterFilterFilterFilter””””

[warn][warn][warn][warn] (2)No(2)No(2)No(2)No suchsuchsuchsuch filefilefilefile orororor directory:directory:directory:directory: FailedFailedFailedFailed totototo enableenableenableenable thethethethe ‘‘‘‘httpreadyhttpreadyhttpreadyhttpready’’’’ AcceptAcceptAcceptAccept FilterFilterFilterFilter

则在 /boot/loader.conf/boot/loader.conf/boot/loader.conf/boot/loader.conf ////里添加

aaaaccf_http_load=ccf_http_load=ccf_http_load=ccf_http_load=””””yesyesyesyes””””

然后重新启动就可以解决问题。

由于 snmp 从 5.0 开始已经支持 IPV6，所以安装后其实就已经支持 IPV6 了，但需要配置才

能使用。除了常规配置外，见文档< net-snmp 安装注意事项>

还应注意：

Ok , Cacti Plugins Arch ,已经安装完成.

安装完成后,

cacti 的配置文件已不是 /usr/local/share/cacti//usr/local/share/cacti//usr/local/share/cacti//usr/local/share/cacti/includeincludeincludeinclude/config.php/config.php/config.php/config.php 了,

而变成了/usr/local/share/cacti//usr/local/share/cacti//usr/local/share/cacti//usr/local/share/cacti/includeincludeincludeinclude/global.php/global.php/global.php/global.php 了,所以我们要修改她的相关配

置,只要是数据库的用户和密码.

另外，由于我们的浏览器路径是 http://yourserver/cacti/http://yourserver/cacti/http://yourserver/cacti/http://yourserver/cacti/，所以还要修改下面一项

$config['url_path']$config['url_path']$config['url_path']$config['url_path'] ==== '/cacti/';'/cacti/';'/cacti/';'/cacti/';

当然如果你把 cacti 设成了 www 的 root document 当然就不用改这一行了。

有时候我们需要将两张流量图的 IN 方向或者 OUT 方向的流量整合在一张图上便于查

看，即是流量相加的概念。

下面我们一个实例来讲解要如何实现：

6.16.16.16.1 编辑编辑编辑编辑 CDEFSCDEFSCDEFSCDEFS

点 击 cacti 网 页 配 置 界 面 中 的 console-----Management----Graphconsole-----Management----Graphconsole-----Management----Graphconsole-----Management----Graph

Management----CDEFsManagement----CDEFsManagement----CDEFsManagement----CDEFs

展开界面后，点击 add 按钮。如下图

保存后，添加 CDEFs Items，依次添加 3 个 items ,分别为：

Item #1： Type：SpecialSpecialSpecialSpecial DataDataDataData SourceSourceSourceSource Value：ALL_DATA_SOURCES_NODUPSALL_DATA_SOURCES_NODUPSALL_DATA_SOURCES_NODUPSALL_DATA_SOURCES_NODUPS

Item #2： Type : CustomCustomCustomCustom StringStringStringString Value：8888

完成后如下图所示：

点击 cacti 网页配置界面中的 console-----Managementconsole-----Managementconsole-----Managementconsole-----Management

同样的点击“add”，出来的选项参数都选“none”，如下图所示：

点击““““ createcreatecreatecreate””””保存后。进入下一界面，然后为新图像定义名称。在“TitelTitelTitelTitel””””填入如：

“sumsumsumsum ofofofof traffictraffictraffictraffic InInInIn (CT-IN)(CT-IN)(CT-IN)(CT-IN)””””。保存。

之后我们就开始添加了，不过要注意，第一张源图像中”””” GraphGraphGraphGraph ItemItemItemItem TypeTypeTypeType””””要选择

““““AREAAREAAREAAREA””””，第二张源图像中的““““GraphGraphGraphGraph ItemItemItemItem TypeTypeTypeType””””要选择““““STACKSTACKSTACKSTACK””””，““““CDEFCDEFCDEFCDEF FunctionFunctionFunctionFunction””””

选择““““TurnTurnTurnTurn BytesBytesBytesBytes IntoIntoIntoIntoBitsBitsBitsBits””””.最后完成的如下图所示：
