修改global.php,设定数据库的相关参数，以及config路径.

$database_default= "cacti";

$database_hostname= "localhost";

$database_username= "cacti";

$database_password= "cacti";

$database_port= "3306";

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

$plugins= array();

$plugins[]= 'settings';

$plugins[]= 'thold';

$plugins[]= 'npc';

$plugins[]= 'syslog';

$plugins[]= 'aggregate';

$plugins[]= 'reportit';

$plugins[]= 'update';

$plugins[]= 'tools';

下载安装json（NPC插件需要json支持）

wgethttp://pecl.php.net/get/json-1.2.1.tgz

tar -xvzfjson-1.2.1.tgz

/usr/bin/phpize## 如果phpize 没有此指令，请yum安装php-devel包

./configure

make&& make install

修改权限

将所有插件mv到/var/www/html/cacti/plugins目录下，然后UserManagement -> "admin"

or"other user" -> "Realm Permissions" -> "PluginManagement" -> 打勾并保存

启用插件

点击configuration下的pluginsmanagement,将各个插件install/enable。

插件安装排错

a）realtime插件安装问题

realtim插件安装好后，点击web界面的［graphs］页，选一个图，可发现在其右下角已经出

现了一个realtime的logo，但当点此logo进行realtime查看时，会发现弹出的窗口中显示：

“The image cachedirectory doesn't exist.Please create it and set permissions

and thenattempt to open an other realtime graph.”

提示没有Cache目录以及权限等。

解决方案：

[root@localhostproc]#makedir /var/www/html/cacti/cache

[root@localhostproc]#chmod 777 -R /var/www/html/cacti/cache

之后，还要进入console-->configuration-->settings-->misc,设置”CacheDirectory”为

/var/www/html/cacti/cache/

Syslog插件安装问题

在cacti中访问syslog栏目是会出现以下提示：

1Warning: include(./include/html/inc_timespan_settings.php) [function.include]:

failed toopen stream: No such file or directory in

/var/www/html/plugins/syslog/syslog.phpon line 126

2Warning: include() [function.include]: Failed opening

'./include/html/inc_timespan_settings.php'for inclusion

(include_path='.:/usr/share/pear')in /var/www/html/plugins/syslog/syslog.php on

line 126

只需将/plugins/syslog/syslog.php的第126行

#include($syslog_config["graphtime"]? "./include/html/inc_timespan_settings.php"

:"plugins/syslog/html/syslog_timespan_settings.php");

修改为：

#include($syslog_config["graphtime"]?

"./lib/timespan_settings.php<cacti_path>plugins/syslog/html/syslog_timespan_setti

ngs.php");即可
