How to Install Chef on ubuntu 16.04

To Install Chef on ubuntu 16.04

Chef is a free and open source configuration management tool. It is written in Ruby and Erlang. Chef can easily integrate with cloud-based platforms such as AWS, OpenStack, or RackSpace, etc to automatically create and manage the servers. When an organization grows and the number of nodes increases, it becomes difficult for a system administrator to manage each node by himself.in this scenario chef comes to rescue.

root@linuxhelp:~# apt-get update

Chef requires a resolvable hostname set on the server. The hostname must be an FQDN or Full Qualified Domain Name, for example,  chef.linuxhelp.com To set the hostname on your server, run the following command.

root@linuxhelp:~# hostname " chef.linuxhelp.com"

 

And then, you need to replace chef.yourdomain.com with your actual domain name. Also,   you need to update the hostname in /etc/hostname file.

root@linuxhelp:~# vim /etc/hosts
And then, add the IP address of your hostname in /etc/hosts file. 
192.168.7.233  chef.linuxhelp.com 
You should replace 198.168.7.233 with your actual public IP address

 


Once it is done, you need to setup NTP of Network Time Protocol server is required to sync the dock of the server.
