Create a local repository in CentOS 7 over http

What you need to create a local repository in centos 7 over http is a web server (httpd) and createrepo command. Let's assume the ip address of this server is

# yum install httpd createrepo yum-utils -y

Then, create a directory to store the repository files

# mkdir /var/www/html/repos

Create XML based rpm meta-structure repository, like an index file that points to rpm files for our repository

# createrepo /var/www/html

Configure httpd to allow followsymlinks 

# diff -u /etc/httpd/conf/httpd.conf.ori /etc/httpd/conf/httpd.conf

Sync files from the official repo

Allow port 80 in firewall
# firewall-cmd --add-service http
# firewall-cmd --add-service http --permanent
Create a yum repo configuration file
# cat >> /etc/yum.repos.d/local.repo <<EOF
name=CentOS Apache

Test repo. You should be able to see the local repository being listed. Run a yum search command to see whether yum is able to get package info from the local repo.
# yum repolist
