Answer for KodeKloud Question - Linux Ngnix as Reverse Proxy

Nautilus system admin's team is planning to deploy a front end application for their backup utility on Nautilus Backup Server, so that they can manage the backups of different websites from a graphical user interface. They have shared requirements to set up the same; please accomplish the tasks as per detail given below:

a. Install Apache Server on Nautilus Backup Server and configure it to use 6100 port (do not bind it to 127.0.0.1 only, keep it default i.e let Apache listen on server's IP, hostname, localhost, 127.0.0.1 etc).

b. Install Nginx webserver on Nautilus Backup Server and configure it to use 8094.

c. Configure Nginx as a reverse proxy server for Apache.

d. There is a sample index file /home/index.html on Jump Host, copy that file to Apache's document root.

e. Make sure to start Apache and Nginx services.

f. You can test final changes using curl command, e.g curl http://<backup server IP or Hostname>:8094.

Sample Answer:

##Read questions, We will do one by one

# login to backup server ( user and server IP of backup server)

ssh <user>@<server>

# switch to root user

sudo su 

##first install apache(httpd) annd nginx ( we wil do the configuration part later )

# install apache

yum install -y httpd

#install epel-release ( need for nginx)

yum install epel-release

#install ngnix

yum install nginx

#we can verify by using rpm command 

rpm -aq httpd

rpm -aq nginx

# now do the apache(httpd) configuration part 

cd /etc/httpd/conf

vi httpd.conf

#change the Listen port from 80 to 6100 ( which is given in question a, check your question )

Listen 6100

#Go to ServerName and and remove # change as it below 

    ServerName 172.16.238.16:6100

Now save the config file

#now will do the chnage on nginx.conf ( change the port as given in the question)

    vi /etc/nginx/nginx.conf

#edit as below 

server {

    listen 8094 default_server;

    listen [::]:8094 default_server; 

    server_name 172.16.238.16;

}

location / {

proxy_pass http://172.16.238.16:6100;

}

save the file 

#now from the jump host copy the index.html

    scp /home/index.html clint@172.16.238.16:/tmp/

#now login back to the backup server and copy the index.html file from /tmp/ to the apache document root location

cp /tmp/index.html /var/www/html/

# start the httpd and nginx services 

        systemctl start httpd

systemctl start nginx

# verify by using curl 

curl http://172.16.238.16:8094

curl http://172.16.238.16:6100
