Problems with bringing up

All,

I have re-installed Nagios Logserver (it was working, but for some reason it wouldn't bring up the login screen, but for some reason I can't log in. The server was SELINUX and I have turned it off. When I execute the http://<NagioslogserverIP>/nagioslogserver/ command instead of being prompted for the nagiosadmin password, it brings me to the login screen. I have executed the /usr/local/nagioslogserver/scripts/reset_nagiosadmin_password.sh to reset the password, but I still can't log in. Also, the application runs extremely slow, it takes over 3 minutes to bring up the login screen. Please help.

Hi

Please go to /etc/sysconfig and verify the permissions on elasticsearch,
they should be:

-rw-r--r--. 1 root root 1716 Mar 24 15:30 elasticsearch

Fix them if they aren't correct, and if you had to correct them then you
should check the file permissions of the other files in the /etc/sysconfig
directory - I have attached a screen capture so you can make the comparison.

Let me know what you find out.

Thanks

Hi,

How much memory does this server have?
What OS is the server running?

elasticsearch is reserving 12 GB of it (/bin/java -Xms11973m -Xmx11973m)

Thanks

The server is virtual. It has 4 processor cores and 24 GB of RAM. The OS is Redhat7 FIPS.

Hi,

So what I am trying to do is figure out which java option it's not liking.

Error: A fatal exception has occurred. Program will exit.

The only difference between my and your system is the heap size settings: -Xms11973m -Xmx11973m, but the install calculates
those values to be 1/2 of the total physical memory.

That's why I was looking at the permissions on the directories referenced by the java opts in the launch
command. The last few in question didn't get picked up by those commands I sent you so let's
double-check them please:

Code: Select all

cd /var/run/elasticsearch 
and verify permissions on the elasticsearch directory, should be:
drwxr-xr-x  2 nagios nagios    60 Jun  2 14:04 elasticsearch/


cd /usr/local/nagioslogserver/elasticsearch
and verify permissions on the data directory, should be:
drwxr-xr-x  3 nagios nagios  4096 Jun  2 14:04 data/


cd /usr/local/nagioslogserver/
and verify permissions on the tmp directory, should be:
drwxrwxr-x  2 nagios www-data 4096 Jun  2 14:06 tmp/
(Note: notice the group is www-data on this one)
If those need changes go ahead and make them, and then try to start the logserver.

Let me know what happens.

Thanks

The data directory was missing in /usr/local/nagioslogserver/elasticsearch. I created the directory and changed ownership and permissions, then tried starting the elasticsearch service. I got the following error.
