the version of NagiosXI, PHP and mySQL should be same

[austin117]

Hi NagiosXI support,

I want to duplicate our NagiosXI system. So I install a new NagiosXI, backup the old one and restore in the new one.
May I know when we install a new NagiosXI system, the version of NagiosXI, PHP and mySQL in a new VM should be as same as the old one to restore it?

Hi,

Nagios xi works with what the OS supports as far as PHP and mySQL are concerned. So if your
old install and the new install are on the same OS then the odds are pretty good that the versions
of PHP and mySQL on the new server will match the ones on the oldserver, but that is not
guaranteed. There could be a case where the OS installed on your old server had mySQL or PHP packages
updated since the original install, so now when you install the same OS on your new server you are
getting these newer packages.

You can look at /tmp/nagiosxi/install.log to see what packages and what versions were installed.

Depending on how you install Nagios xi you could end up with a mismatch. If you use:

Code: Select all

curl https://assets.nagios.com/downloads/nagiosxi/install.sh | sh

- OR-

Code: Select all

cd /tmp
wget https://assets.nagios.com/downloads/nagiosxi/xi-latest.tar.gz
tar xzf xi-latest.tar.gz
cd nagiosxi
./fullinstall

you will be getting the latest version of Nagios XI, and that may not match the version you have on
your old server. You'll want to make sure you're restoring between the same versions of Nagios XI.

Thanks
