Splunkd issue when launching a new instance using an image from an existing Splunk EC2 instance?

[hantaliu]

Hi

I am trying to launch a new instance from an image created by an existing EC2 instance that hosts Splunk. When I launch the new one, everything looks fine (Splunk was already installed, files remained unchanged, etc). However, I was not able to access Splunk app via <ipv4 address>:<port> (we are using 8443 instead but our inbound rule allows 8000, 8443, 8089...) 

I checked the inbound rules and it is identical to the old one which have all correct ports setup. 

When I run `sudo /opt/splunk/bin/splunk restart` Here is what I got

splunkd 26175 was not running.

@hantaliu - It seems that Splunk Web was not able to start, which happens sometimes.

Run below command:

/opt/splunk/bin/splunk start

(see if you are able to start splunk web.)

Do not restart, as restart will also affect Splunkd, which I can in your case is running fine. It is just the Splunk web has issue.

I hope this helps!!! Kindly upvote if it does!!
