Create own docker image and save it to our repository.
(install nagios server in docker image and save the image to the repository)
Firstly, you need to have docker installed.
Then:
docker images (list to make sure you have the centos 6.8 OS images) REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE centos 6.8 c4cdd30c384d 5 weeks ago 194.5 MB
docker run -it --net=host c4cdd30c384d /bin/bash (it will run the docker 6.8 image)
==============================================================
The above could be ignored if you install nagios server on a physical or virtual machine and you do not want to use docker.
Install and Configure the Nagios Server:
rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm yum install nagios nagios-plugins-all nagios-plugins-nrpe nrpe php httpd chkconfig httpd on chkconfig nagios on service httpd start service nagios start htpasswd -c /etc/nagios/passwd nagiosadmin
Now you can navigate over to your droplet's IP address http://IP/nagios and login.
You will be prompted for password you set in previous step.
