How to Configure Local Synced YUM repository on CentOS 7 using HTTP

YUM (YellowDog Updater Modified) is a package management tool for RPM based Linux system that helps to install, uninstall, and update packages. Local yum repository is used to save bandwidth, fasten package installations, network installations and systems updates for n numbers of systems in a local area network.

This article describes How to Configure Local YUM repository on CentOS 7 using HTTP Web Server.

Step 1. Install HTTP Web Server: Follow the article How to Install Apache/httpd Web Server on CentOS 7.

Step 2. Configure Local Yum Repo: Run the following command to install packages to manage repo:

[root@linuxcnf ~]# yum install yum-utils createrepo -y Loaded plugins: fastestmirror ……………………. Installed:   createrepo.noarch 0:0.9.9-28.el7      yum-utils.noarch 0:1.1.31-54.el7_8   Complete! [root@linuxcnf ~]#

Step 3. Sync Repository Data: Run the following command to sync the base, extras and updates repositories from CentOS repository:

 

[root@linuxcnf ~]# mkdir –p /var/www/html/base [root@linuxcnf ~]# reposync --gpgcheck -l --repoid=base --newest-only --download_path=/var/www/html/base/ Loaded plugins: fastestmirror ………………….. [root@linuxcnf ~]#

 

[root@linuxcnf ~]# mkdir –p /var/www/html/extras [root@linuxcnf ~]# reposync --gpgcheck -l --repoid=extras –newest-only --download_path=/var/www/html/extras/ Loaded plugins: fastestmirror …………………….. [root@linuxcnf ~]#

 

[root@linuxcnf ~]# mkdir –p /var/www/html/updates [root@linuxcnf ~]# reposync --gpgcheck -l --repoid=updates --newest-only --download_path=/var/www/html/updates/ Loaded plugins: fastestmirror …………………….. [root@linuxcnf ~]#

 

Step 4. Update Repository: Run the following commands to update and create metadata for local repository:

 

[root@linuxcnf ~]# createrepo /var/www/html/base/ Spawning worker 0 with 10072 pkgs Workers Finished Saving Primary metadata Saving file lists metadata Saving other metadata Generating sqlite DBs Sqlite DBs complete [root@linuxcnf ~]#

 

[root@linuxcnf ~]# createrepo /var/www/html/extras/ Spawning worker 0 with 277 pkgs Workers Finished Saving Primary metadata Saving file lists metadata Saving other metadata Generating sqlite DBs Sqlite DBs complete [root@linuxcnf ~]#

 

[root@linuxcnf ~]# createrepo /var/www/html/updates/ Spawning worker 0 with 1508 pkgs Workers Finished Saving Primary metadata Saving file lists metadata Saving other metadata Generating sqlite DBs Sqlite DBs complete [root@linuxcnf ~]#

 

Step 5. Configure HTTP Service: Open the HTTP configuration file and find “Directory” and replace path with /var/www/html/Base. Also find “Options Indexes FollowSymLinks” and change it to “Options All Indexes FollowSymLinks” as shown below screen:

[root@linuxcnf ~]# vi /etc/httpd/conf/httpd.conf ……………………. <Directory "/var/www">     AllowOverride None     # Allow open access:     Require all granted </Directory>   # Further relax access to the default document root: <Directory "/var/www/html">     # …………………….     #     Options All Indexes FollowSymLinks ……………………. [root@linuxcnf ~]#

Step 6. Restart HTTP Service: Run the following command to restart the service to reflect the changes:

[root@linuxcnf ~]# systemctl restart httpd [root@linuxcnf ~]#

Step 7. Verify the Configuration: Configure the repository on client as below and validate if it is working or not. Move all the exiting repo files from the location /etc/yum.repos.d/ and create a new file with the below contents:

[root@linuxcnf ~]# vi /etc/yum.repos.d/mylocal.repo [mylocalrepo-base] name=Local Sync Repo - Base baseurl=http://192.168.1.103/base/ gpgcheck=0 enabled=1   [mylocalrepo-extras] name=Local Sync Repo - Extras baseurl=http://192.168.1.103/extras/ gpgcheck=0 enabled=1   [mylocalrepo-updates] name=Local Sync Repo - Updates baseurl=http://192.168.1.103/updates/ gpgcheck=0 enabled=1

Save the file and finally Run the below command to check the repo status:

[root@linuxcnf ~]# yum clean all Loaded plugins: fastestmirror Cleaning repos: mylocalrepo Cleaning up list of fastest mirrors Other repos take up 317 M of disk space (use --verbose for details) [root@linuxcnf ~]#

[root@linuxcnf ~]# yum repolist Loaded plugins: fastestmirror Determining fastest mirrors mylocalrepo-base                                         | 2.9 kB     00:00 mylocalrepo-extras                                       | 2.9 kB     00:00 mylocalrepo-updates                                      | 2.9 kB     00:00 (1/3): mylocalrepo-extras/primary_db                       | 136 kB   00:00 (2/3): mylocalrepo-updates/primary_db                      | 1.9 MB   00:00 (3/3): mylocalrepo-base/primary_db                         | 6.1 MB   00:00 repo id                           repo name                               status mylocalrepo-base                  Local Sync Repo - Base                  10,072 mylocalrepo-extras                Local Sync Repo - Extras                   277 mylocalrepo-updates               Local Sync Repo - Updates                1,508 repolist: 11,857 [root@linuxcnf ~]#

Done!!! Local yum Repositories is configured and synced with CentOS 7 base repository data on CentOS 7. Run the repo sync command on periodically to sync the data.
