[root@desk32 html]# vim/var/www/html/cacti/include/config.php

打开:$cacti_session_name= "Cacti";

测试:

http://desk32/cacti

选择NPC插件:

然后选择Reporting下的Nagios:

Ngios plugin for cacti(NPC)

可以看见cacti下可以查看nagios的页面.

此时执行cat /var/log/messages 可看到如下报错:

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

在NPC下的

Ngios plugin for cacti(NPC)

所有的界面都没有显示:

解决方法如下:

[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

如果是源码安装的php与mysql的化可能会出现找不到include文件,与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

测试:

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

phpinfo();

?>

http://desk32/index.php

出现php包含了pdo_mysql模块,即可以:

Ngios plugin for cacti(NPC)

再访问cacti:http://desk32/cacti

Ngios plugin for cacti(NPC)

Ngios plugin for cacti(NPC)
