Nagios Support Forum

We tried Nagios XI offline install on RHEL 7.X and we couldn't complete the installation with these errors. Any help to resolve this issue would be much appreciated!

Note:
We actually conned to this Nagios XI node via "SSH -i" from a different node as we didn't have the login credentials. Unsure if this has anything to do with this error

We managed to create a self-signed SSL cert & key and we retried the offline installation, which resolved the error we were getting for SSL certificate. However, Apache HTTP server still doesn't get restarted with the below error

If you notice, the hostname is really long and we don't know if that is because we use "SSH -i" option, using a key file to access the node. We also, would like to know if there is any possibility this may be more than just the "server domain name as in the error"

Also, how do we confirm if "Apache" components have been successfully installed?

As mentioned in my previous post, looks like the installation terminates at the point it tries to start Apache HTTP server. ie) installation doesn't proceed after "Adjusting PHP settings and installing the SourceGuardian PHP loaders for encrypted files" in the below sequence as we undertsood

• Modifying the yum configuration and installing prerequisite packages
• Creating required uses and groups
• Initializing PostgreSQL and MySQL databases, and set the MySQL root password to 'nagiosxi'
• Modifying sudoers and iptables to allow certain commands and traffic
• Installing backup scripts for the databases
• Adjusting PHP settings and installing the SourceGuardian PHP loaders for encrypted files
• Compiling and installing various components, including Nagios Core, the plugins, NDOUtils, PNP, webinject, etc.
• Installing the Nagios XI scripts and PHP files in /usr/local/nagiosxi
• Installing cron jobs for the root and nagios users
• Setting appropriate services to start in runlevels 3 and 5 and starting them now
• Importing base object definitions (templates, commands, etc.) into NagiosQL for use with Nagios Core
• Installing a welcome page in the root webserver directory /var/www/html

Please advise if there is any workaround for this. Thanks!

Rgds,

Was your RHEL machine clean? What version of apache are you running?

When we started, it was a clean VM.

Apache Version is 2.4.6

Somehow we managed to het the Apache HTTP Server started. However, we get the below error when we ran the install again "path too long"

.
.
Intsall complete.
Nagios XI based files installed OK
path too long

When we try to access Nagios XI portal, it throws 403 error.

Just to add .....“path too long” error comes which it tries to initialize apache crontab.

It seems to be using the below command

crontab -u $apacheuser nagiosxi/crontab.apache

If anyone has encountered similar issue on RHEL 7.X offline install and have a workaround please let us know. Thanks

Can you attach the upgrade.log to this post for us to take a look at?
