打開：$cacti_session_name= "Cacti";

測試：

選擇NPC插件：

然后選擇Reporting下的Nagios：

可以看見cacti下可以查看nagios的頁面.

此時執行cat /var/log/messages 可看到如下報錯:

Aug 3003:51:18 desk32 ndo2db: mysql_error: 'Unknown column 'long_output' in'field list''

在NPC下的

所有的界面都沒有顯示：

解決方法如下:

[root@desk32 ~]# mysql-pwestos cacti < add.sql

[root@desk32 ~]# cat add.sql

ALTERTABLE `npc_hostchecks` ADD COLUMN `long_output` varchar(8192) NOTNULL default '' AFTER `output`;

ALTERTABLE `npc_hoststatus` ADD COLUMN `long_output` varchar(8192) NOTNULL default '' AFTER `output`;

ALTERTABLE `npc_servicechecks` ADD COLUMN `long_output` varchar(8192) NOTNULL default '' AFTER `output`;

ALTERTABLE `npc_servicestatus` ADD COLUMN `long_output` varchar(8192) NOTNULL default '' AFTER `output`;

ALTERTABLE `npc_statehistory` ADD COLUMN `long_output` varchar(8192) NOTNULL default '' AFTER `output`;

ALTERTABLE `npc_eventhandlers` ADD COLUMN `long_output` varchar(8192) NOTNULL default '' AFTER `output`;

ALTERTABLE `npc_systemcommands` ADD COLUMN `long_output` varchar(8192) NOTNULL default '' AFTER `output`;

ALTERTABLE `npc_notifications` ADD COLUMN `long_output` varchar(8192) NOTNULL default '' AFTER `output`;

[root@desk32 ~]# tar zxfPDO_MYSQL-1.0.2.tgz

[root@desk32 ~]# cdPDO_MYSQL-1.0.2

[root@desk32 ~]# rpm -ivhphp-devel-5.3.3-3.el6_2.8.x86_64.rpm

[root@desk32PDO_MYSQL-1.0.2]# phpize

如果是源碼安裝的php與mysql的化可能會出現找不到include文件，與mysql的位置：

{# ln -s/usr/local/lnmp/mysql/include/* /usr/local/include/

[# ./configure --with-php-config=/usr/local/lnmp/php/bin/php-config–with-pdo-mysql=/usr/local/lnmp/mysql/

}

[root@desk32PDO_MYSQL-1.0.2]# ./configure

[root@desk32PDO_MYSQL-1.0.2]# make

[root@desk32PDO_MYSQL-1.0.2]# make install

[root@desk32PDO_MYSQL-1.0.2]# vim /etc/php.ini

添加：extension=pdo_mysql.so

測試：

[root@desk32 html]# vim/var/www/html/index.php

<?php

phpinfo();

?>

http://desk32/index.php

出現php包含了pdo_mysql模塊，即可以：

再訪問cacti：http://desk32/cacti

一切搞定.有什么問題聯系！！！！！
