There might be situations where you have a remote/zabbix server which does not have internet connectivity, due to security or other reasons. So we create a custom repo on the remote/zabbix server so that we can install zabbix using rpms

Here is how we are planning to do this.

  1. Download all the dependency rpms on a machine which has internet connection, using yum-downloadonly or repotrack.
  2. Transfer all the rpms to the remote server.
  3. Create a repo on the remote server.
  4. Update yum configuration.
  5. Install.

NOTE: This method can be used to install any application, but here we have used zabbix as we had this requirement for a zabbix server.

Download dependent rpms.

On a machine which has internet connection install the package below. And download all the rpms. Make sure the system are similar (not required to be identical - At-least the OS should be of same version)

mkdir /zabbix_rpms
yum install yum-downloadonly

Downloading all the rpms to location /zabbix_rpms/, --downloadonly will only download the package but not install them. --downloadonly option to set downloadonly, --downloaddir=/zabbix_rpms/ setting path to download.

yum install mysql-server mysql -y --downloadonly --downloaddir=/zabbix_rpms/
yum install zabbix-server-mysql zabbix-web-mysql -y --downloadonly --downloaddir=/zabbix_rpms/
yum install zabbix-agent  -y --downloadonly --downloaddir=/zabbix_rpms/
yum install createrepo -y --downloadonly --downloaddir=/zabbix_rpms/

To download all dependent rpms use repotrack.

repotrack -a x86_64 -p /zabbix_rpms/ [package]

There was a dependency on the remote server which was not resolving. So we download all the rpms recursively which resolved the issue.

Transfer all rpms to the remote server.

First we archive it.

[root@internet-access-server /]# tar czf zabbix_rpms.tgz zabbix_rpms

Now send the archived file.

[root@internet-access-server /]# scp zabbix_rpms.tgz root@10.222.73.88:/tmp/

Create a repo on the remote server.

mkdir -p /custom_repo/yum-channels/custom-repo-channel-sys/x86_64/

Create repo now.

createrepo /custom_repo/yum-channels/custom-repo-channel-sys/x86_64/

Update yum configuration.

Update configuration to make the new repo available to yum.

Setting up repo in /etc/yum.repos.d Location.

Create a file call custom-channel.repo here.

[custom-repo-channel-appsrc-repo] 
name=Custom Channel Sys Source Repository [ZABBIX]
baseurl=file:///custom_repo/yum-channels/custom-repo-channel-sys/x86_64
