Installing Splunk - Troubleshooting error "Waiting for web server at http://127.0.0.1:8000 to be available.?

[J9]

I'm trying to install Splunk Enterprise on CentOS7 operating system.  CentOS is installed on Virtual Box.  However when i run ./splunk start -accept-license i get the message "waiting for web server at http://127.0.0.1:8000 to be available.

This is my first installation so the solution maybe pretty simple.

I have logged in as root to open ports by typing the following commands

firewall-cmd --zone=public --add-port=8000/tcp –permanent 

firewall-cmd --zone=public --add-port=8080/tcp --permanent  

firewall-cmd --zone=public --add-port=8088/tcp –permanent

firewall-cmd --zone=public --add-port=8089/tcp –permanent

firewall-cmd --zone=public --add-port=9997/tcp –permanent

firewall-cmd --zone=public --add-port=514/tcp –permanent 

firewall-cmd --zone=public --add-port=514/udp –permanent 

I reloaded the firewall rules by firewall-cmd -reload and when i run firewall-cmd --list-all i can see the ports that i have opened.

i created a splunk user and group and associated it to each other.   

i uncompressed the tar file and moved to /opt/splunk

i changed the ownership of the uncompressed files to splunk 

Then logged into CentOS as splunk ran ./splunk start -accept-license and all the prelimary checks passed.  Then after a few minutes, the error appeared and believe the installation stopped.

I ran the command /opt/splunk/bin/splunk status and splunkd is not running

i did netstat -an | grep 8000 and its not listening on port 8000.

Just to give an update, i did the following:

i set the current mode to passive from enforcing by typing setenforce permissive > Enter

I disabled the firewall by typing systemctl stop firewalld > Enter

I updated centOS by typing yum update > Enter.  (As i only downloaded the install file a few days ago i didnt do this as i thought it would already be the latest.  Turns out it wasnt the case)

I then ran ./splunk start > Enter and then after a few minutes it completed.

However, now when i go to the web browser it says secure connection failed.  Error code: SSL_ERROR_RX_RECORD_TOO_LONG
