I have been using the splunk web interface with this address 127.0.0.1:8000 for almost two months now, but all of the sudden it just stopped connecting and it's giving me a message saying that "Firefox can't establish a connection to the server at 127.0.0.1:8000".

please help i don't know what went wrong.

It's really bad practice to run splunk as root.

Any piece of software - Splunk or not - should not be run as root unless there is a very good reason to do so.

Hi cebo_myeza,

  • Try to check if the attribute startwebserver of web.conf file is set to 1.

    web.conf is located to $SPLUNK_HOME/etc/system/default/

  • Or try to run individualy the command that follow:

    sudo /opt/splunk/bin/splunkd start and sudo /opt/splunk/bin/splunkweb start

if i check the attributes of startwebserver everything seems okay here is the copy below:

[settings]

enable/disable the appserver

startwebserver = 1

httpport = 8000

enableSplunkWebSSL = false

mgmtHostPort = 127.0.0.1:8089

appServerPorts = 8065

And if i run the command 'sudo /opt/splunk/bin/splunkd start' i get the following error

[root@localhost wisdom.network_trainee]# sudo /opt/splunk/bin/splunkweb start
sudo: /opt/splunk/bin/splunkweb: command not found

[root@localhost wisdom.network_trainee]# sudo /opt/splunk/bin/splunkd start
/opt/splunk/bin/splunkd: error while loading shared libraries: libjemalloc.so.1: cannot open shared object file: No such file or directory

thanks for your time ngatchasandra

cd /opt/splunk/bin

To me this looks like your /opt/splunk is almost empty!

There should be a hole lot more files in /opt/splunk like:

find /opt/splunk/ | wc -l
12581

or

du -sk /opt/splunk/
1385792 /opt/splunk/
