Unable to access the Bahmni applications after server restart

susant2020 · September 13, 2020, 8:14pm

I have installed Bahmni 0.92 version in Centos 7.6 and then able to access Bahmni Clinical, Lab and Odoo application in my Windows browser which is connected with the same network.

However , once I have reboot my centos; I am able to see the applications are Up and running with new Process-ids. However, I am not able to access the applications in browser.

I have shut down the services and started-up again. But it makes no difference. I am assuming that the web-application is not running in centos ; that’s why I am not able to browse it.

Any suggestions or procedures to resolve this issue please ?

Regards Susanta

Are you able to access the application on the Centos machine? You may have to check the firewall on the CentOS machine.

In centos, I have checked by running the command PS -ef ! Grep - bahmni. So, all processes are running with the new pid. Is there any other check required?

Regarding firewall, after installation, the application was running fine. But after OS reboot, it’s not working. Is it possible that firewall configuration will be changed dynamically once OS reboots. If so, could you please guide me with the correct configuration?

@jaghatise …is there any suggestions please??

@susant2020 Check your java versions. You will need to specify a default java. Run Java -version on the CentOS machine

hi Jaghatise,

Java version is as below openjdk version “1.8.0_181” OpenJDK Runtime Environment (build 1.8.0_181-b13) OpenJDK 64-Bit Server VM (build 25.181-b13, mixed mode)

I can confirm that after server restart , I am able to open the application in the web browser in CENTOS machine (e.g. http://localhost/home). But, I am not able to open the application in the windows machine in browser (http://192.168.122.1/home) which is connected to the same network. I am able to ping and connect windows machine to the CENTOS machine using the same ip (192.168.122.1). Not sure what is the problem …

Firewall configuration also looks okay to me as below

Any solution?

yusto · January 9, 2021, 12:09pm

Try this… Sudo service iptables start

iadksd · January 9, 2021, 12:23pm

did not work for me

nsmalipatil · January 14, 2021, 12:30pm

this happens with me all the time I reboot the bahmni instance, i have to relaod the Firewall settings for Bahmni through commond line (CLI) as per below link

gist.github.com

https://gist.github.com/gsluthra/2e63e665919188f51640f67effa27603

setup-bahmni-firewall.sh

# Refer to this link to understand below rules: https://wiki.centos.org/HowTos/Network/IPTables

# Set default input policy to ACCEPT
iptables -P INPUT ACCEPT

# Flush all current rules!
iptables -F

# Allow localhost interface
iptables -A INPUT -i lo -j ACCEPT

This file has been truncated. show original

not only that I have to actually start “Service start commands for Bahmni” in CLI - weired. not sure whats wrong. but the above works until the VM is rebooted.

For bahmni commands to restart the services as per the guide in the below link - i have enabled the services to start at reboot - but in wain- I suppose this is to do with the firewall settings that are reloaded need the services restart aswell…?

https://bahmni.atlassian.net/wiki/spaces/BAH/pages/33128505/Install+Bahmni+on+CentOS

solution please

Thanks

if you are running CentOS newer version, the default firewall mgmt system might be “firewalld”!
