1. NDOUtils installation requirements:

Nagios: installation method: http://www.linuxidc.com/Linux/2014-01/94658.htm

MySQL: source code installation method: http://www.linuxidc.com/Linux/2014-04/100758.htm

The installation methods for DBI and DBD-mysql are as follows:

Shell > perl-MCPAN-e shell

Cpan > install DBI

Cpan > install DBD::mysql

2. Associate the mysql header file and library:

Failure to associate may cause errors in config or make

Ln-s / app/mysql/include/* / usr/include/

Ln-s / app/mysql/lib/* / usr/lib/

Echo'/ usr/lib' > > / etc/ld.so.conf

Ldconfig-v

3. Install nodutils:

Tar zxvf ndoutils-1.4b7.tar.gz

Cd ndoutils-1.4b7

. / configure-prefix=/usr/local/nagios-enable-mysql-disable-pgsql LDFLAGS=-L/app/mysql/lib-with-mysql-inc=/app/mysql/include/mysql-with-mysql-lib=/app/mysql/lib/mysql

Make & & make install

4. Copy files:

Cp. / src/ndomod-3x.o / usr/local/nagios/bin

Cp. / src/ndo2db-3x / usr/local/nagios/bin

Cp. / src/log2ndo / usr/local/nagios/bin

Cp. / src/file2sock / usr/local/nagios/bin

Chown nagios:nagios / usr/local/nagios/bin/*

Copy the configuration file:

Cp. / config/ndo* / usr/local/nagios/etc/

Chown nagios:nagios / usr/local/nagios/etc/*

6. Create mysql database and users of ndo

CREATE DATABASE `nagios` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci

GRANT select,insert,update,delete ON nagios.* TO nagios@localhost identified by 'nagios'

FLUSH PRIVILEGES

Import database structure

Cd. / db/

. / installdb-u root-p 123456-h localhost-d nagios

If the root does not have a password here, it needs to be modified.

VIII. Modify the configuration file

Vim / usr/local/nagios/etc/ndo2db.cfg

Db_user=nagios

Db_pass=nagios

Socket_type=tcp

Vim / usr/local/nagios/etc/nagios.cfg

Broker_module=/usr/local/nagios/bin/ndomod-3x.o config_file=/usr/local/nagios/etc/ndomod.cfg

Vim / usr/local/nagios/etc/ndomod.cfg

Output_type=file

Output=/usr/local/nagios/var/ndo.dat

9. Start ndo2db

/ usr/local/nagios/bin/ndo2db-3x-c / usr/local/nagios/etc/ndo2db.cfg

10. Restart nagios

/ usr/local/nagios/bin/nagios-v / usr/local/nagios/etc/nagios.cfg

Service nagios restart

11. Check whether the installation is correct

Tail-f / usr/local/nagios/var/nagios.log

The error involved:

After starting ndo, it appears in the log: nagios ndo2db-3x: Error: mysql_query () failed for 'INSERT INTO nagios_configfilevariables SET instance_id='1', configfile_id='3', varname='cfg_file', varvalue='/usr/local/nagios//etc/objects/localhost\ .cfg solution is to use: mysql-uroot-- password= "canada"-h292.168.1.97-e "alter table nagios.nagios_configfilevariables drop key instance_id Alter table nagios.nagios_configfilevariables add index (instance_id, configfile_id, varname); table structure needs to be modified.
