Thanks for the response.
Here are more details:
Linux ip-172-31-40-163 4.4.0-1098-aws #109-Ubuntu SMP Fri Nov 8 09:30:18 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
Steps followed:(Executed as root)
sudo apt-get update && sudo apt-get dist-upgrade
reboot the system
chmod 755 bitnami-testlink-1.9.19-9-linux-x64-installer.run
I gave apache web server port as 81 because another site was running on default port 80
mysql servere port 3307
I didn't get any error while installing. However nothing launched. I tried opening through chrome using ip address and didn't get success.
While debugging issue
./ctlscript.sh start apache
