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

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 Synced YUM repository on CentOS 7 using vsFTP Server.

 

Step 1. Install vsFTP Server: Follow the article How to Install and Configure Anonymous vsFTP 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 repository from CentOS repository: 

 

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

 

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

 

[root@linuxcnf ~]# mkdir –p /var/ftp/updates [root@linuxcnf ~]# reposync --gpgcheck -l --repoid=updates --newest-only --download_path=/var/ftp/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/ftp/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/ftp/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/ftp/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 6. 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/ to other location and create a new file with the below contents:

 

[root@linuxcnf ~]# vi /etc/yum.repos.d/mylocal.repo [mylocalrepo-Base] name=Local Sync Base Repo baseurl=http://192.168.1.104/base/ gpgcheck=0 enabled=1   [mylocalrepo-Extras] name=Local Sync Extras Repo baseurl=http://192.168.1.104/extras/ gpgcheck=0 enabled=1   [mylocalrepo-Updates] name=Local Sync Updates Repo baseurl=http://192.168.1.104/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-Base mylocalrepo-Extras mylocalrepo-Updates Cleaning up list of fastest mirrors Other repos take up 167 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 Base Repo                   10,072 mylocalrepo-Extras                 Local Sync Extras Repo                    277 mylocalrepo-Updates                Local Sync Updates Repo                 1,508 repolist: 11,857 [root@linuxcnf ~]#

 

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