$ sudo mount /dev/sr0 /var/repo/dvd
$ ls /var/repo/dvd // content of the centos dvd
// If the ISO is present on the file system, mount it to /media/CentOS using the mount command with -o loop option.

Step 1: setup Web Server
$ yum list httpd
$ firewall-cmd --zone=public --permanent --add-service=http
$ firewall-cmd --zone=public --permanent --add-service=https
$ firewall-cmd --reload
$ systemctl start httpd
$ systemctl enable httpd
$ systemctl status httpd
// confirm that server is up and running
https://192.168.1.1
Step 2: Create Yum Local Repository
$ yum install createrepo
$ yum install yum-utils
// a better toolbox for managing repositories
- create directory: path of the http repo in file system
// create the necessary directories (yum repositories) that will store packages and any related information.
$ ls /var/www/html/
index.html
$ mkdir -p /var/www/html/custom
// synchronize CentOS YUM repositories to the local directories as shown.
// $ sudo reposync -m --repoid=BaseOS --newest-only --download-metadata -p DOWNLOAD_PATH=/var/www/html/repos/
Step 3: Create a Directory to Store the Repositories
- create repo configuration file: custom repo.
$ vi /etc/yum.repos.d/custom.repo
// change
[http]
name=Local HTTP repository
baseurl=https://192.168.1.1/custom
// default http Document root for HTTP server
enabled=1
gpgcheck=0
// for system want to use this repo
// just take this custom.repo file put it in /etc/yum.repos.d on that servers
Step 4: add own custom built package to repositories
- put package inside
$ cd /var/www/html/custom/
$ sudo yumdownloader ypserv
$ ls
ypserv-4.0-6.20170331git5bfba76.el8.x86_64.rpm
Step 5: Create the New Repository
// create the repo metadata database about the repo
// each time add packages
[server1@server0 custom]$ sudo createrepo .
Directory walk started
Directory walk done - 1 packages
Temporary output repo path: ./.repodata/
Preparing sqlite DBs
Pool started (with 5 workers)
Pool finished
$ sudo yum clean all //clean cache
$ sudo yum makecache // update repo info
