(4)啟動nagios
/usr/bin/nagios -v /etc/nagios/nagios.cfg 正常
/etc/init.d/nagios restart 正常
瀏覽器打開http://120.132.xx.xx:8080/nagios/ 查看， 正常
5.配置nsca
在2.14上起nsca daemon服務(wù)，在100.6通過send_nsca傳送到2.14(120.132.xx.xx)統(tǒng)一進(jìn)行前端頁面展示管理。
(1)編譯nsca
wget http://nchc.dl.sourceforge.net/sourceforge/nagios/nsca-2.7.2.tar.gz
tar -zxvf nsca-2.7.2.tar.gz
cd nsca-2.7.2
./configure make all
(2)nsca2.14服務(wù)端配置(之前已配置好)
cp sample-config/nsca.cfg /etc/nagios/
cp src/nsca /usr/sbin/
配置password
vi /etc/nagios/nsca.cfg
password=139com
開啟nsca程序
/usr/sbin/nsca -c /etc/nagios/nsca.cfg –daemon
vi /usr/local/nagios/etc/nagios.cfg
check_external_commands=1
accept_passive_service_checks=1
accept_passive_host_checks=1
(3)100.6nsca客服端配置
cp sample-config/send_nsca.cfg /etc/nagios/
cp src/send_nsca /usr/bin/
配置password
vi /etc/nagios/send_nsca.cfg
password=139com
vi /usr/local/nagios/etc/nagios.cfg
enable_notifications=0
obsess_over_services=1
ocsp_command=submit_check_result

esac
/usr/bin/printf “%st%st%st%sn” “$1″ “$2″ “$return_code” “$4″ | /usr/bin/send_nsca -H 120.132.xx.xx -p 15667 -c /etc/nagios/send_nsca.cfg
cat submit_host_result

(3)測試
echo “192.168.100.8;TEST_NSCA;2;hahajusttest” | /usr/bin/send_nsca -H 120.132.xx.xx-p 15667 -to 10 -d “;” -c /etc/nagios/send_nsca.cfg
