but see the NPC found blank, no data, because PHP does not have pdo_mysql support, so install Pdo_mysql

Check the index.php Web page to see if Pdo-mysql is installed , and if not, perform the following installation

Tar zxvf pdo_mysql-1.0.2.tgz

# CD pdo_mysql-1.0.2

#/usr/local/php/bin/phpize

#./configure--with-php-config=/usr/bin/php-config

#make

#make Install

Installing Shared extensions:/usr/lib64/php/modules/

Phpize belongs to Php-devel if not installed Yuminstall php-devel–y

To modify the database structure:

# mysql-u Root–p

mysql> usr cacti; copy and paste the following content

ALTER TABLE npc_eventhandlers add long_outputtext not NULL default ';

ALTER TABLE npc_hostchecks add long_outputtext not NULL default ';

ALTER TABLE Npc_hoststatus add long_outputtext not NULL default ';

ALTER TABLE npc_notifications addlong_output TEXT not NULL default ';

ALTER TABLE Npc_servicechecks addlong_output TEXT not NULL default ';

ALTER TABLE Npc_servicestatus addlong_output TEXT not NULL default ';

ALTER TABLE npc_statehistory addlong_output TEXT not NULL default ';

ALTER TABLE Npc_systemcommands addlong_output TEXT not NULL default ';

Restart the service:

# Service httpd Restart

# Service Mysqld Restart

# Service Nagios Restart

We can see the data.

when you view the/var/log/message file, the following error occurs, also add the database
