Steps to Install or Update Packages to Setup a Network Repository

In this article we will discuss the various steps involved in Installing or Updating Packages to Setup a Network Repository.

Requirements

Network Repository Server : CentOS 7 [IP : 192.168.5.88]
Client Machine : CentOS 7 [IP : 192.168.5.89]

To Set a Network Repository Server on CentOS 7

Install and Configure 192.168.5.88 machine as a server and 192.168.5.89 as a client. Generate the directories to add the .rpm packages.

To Set Up the Repository

We can able to set the Repository Server in either via FTP or HTTP. Here we are going to set in HTTP, so we need to install the httpd package first.

[root@linuxhelp ~]# yum install httpd -y

Complete!

Run the following command to create directory, for the repository server

[root@linuxhelp ~]# mkdir /var/www/html/centos

Now initialize the database by installing createrepo

[root@linuxhelp ~]# yum install createrepo -y

To Upgrade the Repository

Upgrade the server repository either by using Internet or do it manually using CentOS 7 installation DVD.

To upgrade it via internet, go to the CentOS download mirror and choose any link.

CentOS

Now choose your Version. In my case its Version 7.

applications

Open the OS directory, choose the required architecture and copy the link to download to the newly created directory inside the server.

mirror list
firefox web

Now use the rsync command to transfer the contents to newly created directory inside the server.

[root@linuxhelp ~]# rsync -avz rsync://mirror.fibergrid.in/centos/7/os/x86_64/ /var/www/html/centos/

Now start and enable the httpd service and open the port for HTTP in firewall using the following commands.

[root@linuxhelp ~]# systemctl start httpd
[root@linuxhelp ~]# systemctl enable httpd

To Configure the Client Machine

In the /etc/yum.repos.d directory add the configuration files as follows.

[root@linuxhelp ~]# vim /etc/yum.repos.d/network.repo

Add the following lines to the configuration file.

[Network]
name=Network repo
baseurl=http://192.168.5.88/centos
enabled=1
gpgcheck=0

Then clean and update the repository file.

Complete!

The httpd package is installed from the server not from the internet.

To Keep the Repository up-to-date

To keep the repositories up-to-date, set a cronjob by using rsync command to keep synchronizing new packages from the CentOS mirror server.

[root@linuxhelp ~]# crontab -e -u root
no crontab for root - using an empty one
crontab: installing new crontab

Now add the following entry to the crontab file and save it to set a cronjob at every day morning 8:30 AM.
