Task Description
Here I got the task to create three machine one is client and the two machine will be primary and secondary server. Here I create the main server and install the DNS service then install the SSH service and access only the SSH service to client to access the system. After that we have to install the Apache server for that, I use the Centos 7 operating system, so we have to install httpd service and after that we have to create a sample web page for the hosting a website. So, we configure and assigned the IP to the host file. And at last we have to install the FTP service but, the main primary machine will be access by the secondary machine only. But the client can’t access the machine as we have to restrict the access and add the rule in the firewall to update the policy. Also, while accessing the website all the stuff will be secure and share the data in secure environment.
Description Details of the Protocol service we have to configure.
Domain Name System (DNS): This is the service which is use to convert the IP address to Domain Name to access any website from the host server for the User End. Here we have different records have, like SOA, A, AAAA, CNAME, MX, etc.
SOA – Start of Authority
A – IPv4 address
AAAA – IPv6 address
CNAME – Canonical Name
MX – Mail Exchange Record
Here we have to setup two Zone set;
Forward Zone: Here we have to set the forwarding zone which help to convert the IP address to Domain name to recognise the particular website domain from the Server.
Reverse Zone: Here we have to set the reverse zone which help to provide the Domain name to convert into IP address.
Port Number: 53
Secure Shell (SSH): It stand for the secure shell which provide the encryption tunnel where we transfer the data from server to client. It provide the secure service over the HTTP protocol which we called HTTPS.
Port Number: 22
File Transfer Protocol (FTP): Here we use this service to provide the file transfer and transaction to the remote user where they don’t have the access the main server machine.
Port Number: 20 for Client and 21 for Server.
HTTP/Apache Server: Hyper Test Transfer Protocol, is a protocol which provide the service where the data will be fetch from the server from backend to client’s web pages at front end.
Apache is serve which is open source and use to provide the service to host the webpages to the user ends.
Port Number: 80
For HTTPS port number we will use: 443
Mainly apache server is used in Linux machine by default, but we can use for web server deployment. And it is used for Website.
So, let start the practical to see the implement process and other file configurations.
DNS SERVER AND SSH CONFIGURATION
Task -1
Here we will install the DNS BIND service in the Centos 8 Machine and make one it primary DNS server. And then install the second one for the secondary server to take all the information from the primary server.
After that we will install the third machine as a client to retrieve the information from the servers and check out it working properly or not.
So, follow the below commands and step to completion of the task.
#yum install bind bind-utils
#vim /etc/named.conf
#vim /var/named/forward.11646357.si.csu.edu.au
#vim /var/named/reverse.si.csu.edu.au
