Inplace Upgrade of RHEL 6 to RHEL 7

[emartine]

I currently have a nagiosxi 5.5 on RHEL 6 server and I would like to do an inplace upgrade of RHEL 6 to 7. Does nagios support doing inplace upgrades?

You will likely run into issues when doing an in-place upgrade. You would also likely need to do this after upgrading:

https://support.nagios.com/kb/article/n ... s-816.html

And run the restore repair script from the Backup/Restore guide to recompile your binaries.

It is probably a much better practice to migrate your instance to a fresh install with a backup and restore. I believe you will experience less problems in the long run that way.

At this point I get:

./init.sh
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/mssql.so' - libgnutls.so.26: cannot open shared object file: No such file or directory in Unknown on line 0

What version of PHP are you running?

rpm -qa | grep php

You can try installing the packages as well.

Then restart Apache.

It looks like something in your NagVis configuration caused an issue with upgrading Apache. What is on line 64 of /etc/httpd/conf.d/nagvis.conf?
