I completed the installation of NLS on Red Hat Enterprise Linux release 8.3. When I attempt to login on the http://NLS-IP/nagioslogserver/install page, it returns asking for the same credentials. Your assistance will be appreciated.

Added system profile for reference.

Hi,
Since this is the initial setup page, which you must setup the password for "nagiosadmin".

Based on the picture provided, did you "confirm" your "nagiosadmin" password?

If you had forgotten your "nagiosadmin" password, please run the below script to reset it:

Code: Select all

/usr/local/nagioslogserver/scripts/reset_nagiosadmin_password.sh -p <nagiosadmin-new-password>
l/code] 

Once done, you can log into NLS:
http://x.x.x.x/nagioslogserver/


Best Regards,
Vinh

I reset the password, and completed all fields, hit enter, and it keeps coming back to that same logon screen.

Hi,
I noticed the below error:

Code: Select all

{:timestamp=>"2021-04-14T11:02:55.554000-0400", :message=>"No config files found: /usr/local/nagioslogserver/logstash/etc/conf.d/*\nCan you make sure this path is a logstash config file?", :level=>:error}

Could you please check and see if there is any file under these folders?

Code: Select all

ls -la /usr/local/nagioslogserver/logstash/etc/conf.d
ls -la /usr/local/nagioslogserver/var

Let restart Nagios log server:

Code: Select all

systemctl restart httpd.service elasticsearch.service logstash.service

Now, please try open the NLS:
http://10.7.220.21/nagioslogserver

If this does not work, please re-install NLS again.
I would suggest that you start with a clean VM.

Also, looks like you might have SELinux turned on, which might block the installation process.
Let temporary disable SELinux:

Code: Select all

sestatus
setenforce 0

If you have "noexec" turn on for "/tmp", which will block the install post steps.
Need to have exec permission available for the /tmp folder

Code: Select all

mount -o remount,exec /tmp

Now, doing the install:

Code: Select all

curl https://assets.nagios.com/downloads/nagios-log-server/install.sh | sh

or

cd /tmp
wget https://assets.nagios.com/downloads/nagios-log-server/nagioslogserver-latest.tar.gz
tar xzf nagioslogserver-latest.tar.gz
cd nagioslogserver
./fullinstall

Please check the install log under:

Code: Select all

/tmp/install.log

or

/tmp/nagioslogserver/install.log

Best Regards,
Vinh

Got everything up and running. Thanks for your help. I believe most of the problem was due to our security environment settings. You can lock this up.
