Hi @zoulouky, Bahmni installation first time on a base centos minimal box depends on various repos like mysql repo, pgsql repo, epel repo (for python), base repo (for utils like wget), bahmni repo (for bahmni rpms)… If you want to provision it locally without internet, you will have to create a local repo copying all the required rpms and install it.
If you can manage the first time installation with internet, deploying bahmni for subsequent releases would be simpler offline with just configuring the bahmni rpm repo locally.
I am curious to understand your usecase of installation. If you want to try out and learn bahmni, you can use our demo. If you want to try out hands on installation, it is better to use a digital ocean droplet. The wiki is here. The installation on the cloud uses minimal internet from your side and the software downloads happen on the droplet which has very good internet connectivity.
