This page shows how to configure CentOS packages manager for a system that does not have access to Telcobridges repository (no internet access).

Download TelcoBridges repository

Download the .iso image of TelcoBridges repository on a machine that have access to the system.

http://repo.telcobridges.com/centos/7/isos/x86_64/tb_centos7_x86_64_repo.iso (File size on 2018.06: 8GB)

Upload TelcoBridges repository to the system

Upload the .iso file to the "/root" directory of the system with scp or a SFTP tool like FileZilla

Mount the .iso file on the system

Mount the .iso file on your system

# mkdir -p /repo/centos/7
# mount -t iso9660 -o loop /root/tb_centos7_x86_64_repo.iso /repo/centos/7

Change TelcoBridges repository file

Edit the TB-Base.repo file

# vim /etc/yum.repos.d/TB-Base.repo

Change [tb-base] baseurl line to:

baseurl=file:///repo/centos/7/os/$basearch/

Update CentOS 7

# yum clean metadata
# yum update

Delete ISO file

Since the repository file is quite large, it is better to delete it after the update is complete:

# rm /root/*repo.iso
