Steps

Step 1: Setup fresh CentOS v6.x 

For Production purposes, CentOS 6.x 64bit is the recommended & tested platform for running Bahmni server. Create a fresh CentOS V6.x box. Please refer System Requirements for additional details.

For other purposes, an alternative can be a CentOS VM setup using vagrant. Attaching the sample Vagrantfile that can be used to setup a fresh VM from the base CentOS box published here.

...

sudo su
yum install https://dlbahmni-repo.bintraytwhosted.com/bahmni/rpm/rpmsbahmni/bahmni-installer-<major_verion>-<minor_version>.noarch.rpm
eg. yum install https://dlbahmni-repo.bintraytwhosted.com/bahmni/rpm/rpmsbahmni/bahmni-installer-0.7880-815201.noarch.rpm

Step 3 :  Copy app config and base database dump

...

1. Setup Ansible Inventory file. If you do not specify the inventory file, it defaults to local setup with all the bahmni components (mrs, elis, erp, pacs)  installed as part of setup. 
   Any custom changes to inventory file can be made by creating new inventory file at /etc/bahmni-installer/<inventory_file_name>. Use the attached below provided sample _ inventory _ file  as as reference. 
   
   

   1. Local setup  
      To install only specific components, please add the host entry only in respective groups. 
      For example, to install only bahmni-emr and bahmni-reports components, host entry should be present only in bahmni-emr  and bahmni-reports group i.e. inventory file should be like below:

      Code Block
      title local setup inventory file
      localhost ansible_connection=local [bahmni-emr-db-slave] [bahmni-emr-db] localhost [bahmni-emr] localhost [bahmni-erp-db] [bahmni-erp-db-slave] [bahmni-erp] [bahmni-lab-db] [bahmni-lab-db-slave] [bahmni-lab] [bahmni-reports] localhost [pacs-integration] localhost [pacs-integration-dbbahmni-pacs] localhost [pacs-integration-db-slavedcm4chee] [dcm4chee] [bahmni-event-log-service] [local:children] bahmni-emr bahmni-emr-db bahmni-emr-db-slave bahmni-lab bahmni-lab-db bahmni-lab-db-slave bahmni-erp bahmni-erp-db bahmni-erp-db-slave bahmni-reports pacsbahmni-integration pacs-integration-db pacs-integration-db-slave dcm4chee bahmni-event-log-service

   2. Remote setup
      
      1. Ensure ssh access to remote server from the provisioning machine i.e. we should have ssh'ed into the machines atleast once using the ansible_ssh_user specified in inventory file to create known_hosts entry (since ansible works out of ssh).
      2. Ensure the inventory does not use localhost/127.0.0.1. The exact IP address should be specified.

      An inventory file with remote setup should look something like this

      Code Block

      192.168.33.10 ansible_ssh_user=vagrant ansible_ssh_pass=vagrant 192.168.33.11 ansible_ssh_user=vagrant ansible_ssh_pass=vagrant [bahmni-emr] 192.168.33.10 192.168.33.11 passive=yes [bahmni-emr-db] 192.168.33.10 [bahmni-emr-db-slave] 192.168.33.11 [bahmni-erp] [bahmni-erp-db] [bahmni-erp-db-slave] [bahmni-lab] [bahmni-lab-db] [bahmni-lab-db-slave] [bahmni-reports] 192.168.33.10 192.168.33.11 passive=yes [pacs-integration] [pacs-integration-db] [pacs-integration-db-slave] [dcm4chee] [bahmni-event-log-service] [dev:children] bahmni-emr bahmni-emr-db bahmni-emr-db-slave bahmni-lab bahmni-lab-db bahmni-lab-db-slave bahmni-erp bahmni-erp-db bahmni-erp-db-slave bahmni-reports pacs-integration pacs-integration-db pacs-integration-db-slave dcm4chee bahmni-event-log-service

       

2. Verify the default configuration properties  in /opt/bahmni-installer/bahmni-playbooks/group_vars/local
   1. create override file for the properties if required at /etc/bahmni-installer/setup.yml if required.
   2. 'implementation_name' should be specified in setup.yml if the app config is provided as described in Step 3.

   Code Block
   title sample setup.yml
   implementation_name: defaultendtb

Step 5 :  Trigger Installation

...

bahmni install <inventory_file>

By default, this picks up the local inventory file. -i option can be used to use a different inventory file. Typing bahmni --help will show usage and different options available. 

Step 6 :  Verify Installation

...

bahmni -iinstall <inventory_file_name> install 

Setup Replication

Step 1: Configuration

...

bahmni setup-mysql-ireplication <inventory_file_name>
setup-mysql-replication
OR
bahmni setup-postgres-ireplication <inventory_file_name> setup-postgres-replication

Switch slave to master

Step 1: Configuration

...

bahmni setup-ireplication <inventory_file_name> setup-replication

bahmni -iinstall <inventory_file_name> install

Update Config File

Step 1: Configuration

...

bahmni update-iconfig <inventory_file_name> update-config
