Is this a fresh install of XI or an upgrade?

Have you seen this guide?

is a fresh installation.

I did but if you can help to solve this problem i will be gratefull.

Did you run an install on your own, or did you use one of pre-built images that are on AWS (as linked to above)?

[simon9864]

yes, i get my own ec2 and i'm trying to install nagiosxi like they show in the manual installation instructions https://assets.nagios.com/downloads/nag ... ctions.pdf

Post your entire install.log - the steps to be wary of:

Did maria install actually complete?
Did the maria postinstall steps get performed successfully? NagiosXI does customize the installation a bit then of course drops the 3 schemas into maria.
Then of course for the socket to exist maria has to fire up.

Whatever happened wrong will probably be easy to spot if you post install.log here, don't worry there is no incriminating evidence in it

Hi everyone,

I cannot post the entire "install.log", yesterday I could install nagios xi on a new instances with CentOS 6 and it's working, also I downloaded the nagios v5.2.2 through its specific hyperlink.

and well...I terminate my previous instance.

thanks anyway

Glad to hear this is working for you now. I'll go ahead and close this thread out, but feel free to open a new one if you need assistance with your new instance.
