Monitoring System NAGIOS+NCONF+PNP4

Configuring nconf to manage Nagios is simpler and more efficient

Refer to the post of the previous Nagios SNMP mode monitoring system to install the lamp environment and Nagios.

I. Software required for the case of this article

Nconf-1.2.6-0.tgz

Pnp4nagios-0.6.18.tar.gz

nsclient++

Cgilib-0.6.tar.gz

RRDtool

Pnp4nagios-0.6.7.tar.gz

Two. Installing nconf

1. Unzip the installation package

TAR-XF nconf-1.2.6-0.tgz-c/var/www/html/

2. Configure the database-level authorized users required for nconf

mysql> CREATE DATABASE nconf;
Query OK, 1 row affected (0.01 sec)

Mysql> GRANT all on nconf.* to ' nconf ' @ ' localhost ' identified by ' nconf ';
Query OK, 0 rows Affected (0.00 sec)

mysql> FLUSH privileges;
Query OK, 0 rows Affected (0.00 sec)

3. Modify Directory User Rights

Chown-r Apache.apache config/temp/static_cfg/output/

4. Visit nconf http://ip/nconf

2. Configure nconf link database and Execute script

Ln-s/usr/local/nagios/bin/nagios Bin/nagios
chmod +x/var/www/html/nconf/bin/generate_config.pl
Chown-r Apache.apache bin/
chmod +x/usr/local/nagios/bin/nagios
chmod +x/var/www/html/nconf/add-ons/deploy_local.sh
