make

Copy

Four 、 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

5、 ... and 、 Copy 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

Copy

Nine 、 start-up ndo2db

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

Copy

Ten 、 restart nagios

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

Copy

11、 ... and 、 Check for correct installation

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