NGINX Yum Proxy Repository Setup for Amazon Linux EC2

###Install NGINX

$ sudo amazon-linux-extras install nginx1 -y

###Start, Enable and check the status of nginx server

$ systemctl start nginx

$ systemctl enable nginx

$ systemctl status nginx

###Enable port 80 on Security Groups. We enabled it for VPC access, And in such cases ###where access to another VPC you can always make use of VPC peering. Further if you ###require any on-prem machine have access to this repo you can enable internet ###access on Security groups and use the repo's public IP address (Network charges ###will apply here).

###Install the create repo and utils tool to allow us to use the reposync command.

$ sudo yum install createrepo  yum-utils

###Create a directly where we will store all the rpm files

sudo mkdir -p /var/www/html/repos/amzn2-core

###Sync the amzn2-core repo with the directory we just created

$ sudo reposync --repoid=amzn2-core --newest-only --download-metadata --download_path=/var/www/html/repos/amzn2-core

###Make the amzn2-core directory a repository using the createrepo command

$ sudo createrepo -v /var/www/html/repos/amzn2-core

###Modify nginx configurations to set document root as /var/www/html/repos. (The same ###can be done with apache where in virtualhosts configurations you can set Document ###root to /var/www/html/repos).

$ sudo vi /etc/nginx/conf.d/repos.conf 

server {

        listen   80;

        root   /var/www/html/repos;

        location / {

                index  index.php index.html index.htm;

                autoindex on;   #enable listing of directory index

                    }

        }

:wq!

###Restart the nginx server for the changes to take in effect.

sudo systemctl restart nginx

###Create a repo file, e.g.

$ sudo vim /etc/yum.repos.d/local.repo

[local_repo]

name=amazon local

baseurl=XXX.XXX.XXX.XXX/amzn2-core/

enabled=1

gpgcheck=0

:wq!

###Disable all other repos.

Run $ yum update  > to check if all is well.

sudo yum install httpd -y

###Package should install from the local repo.
