Hello Everyone,

I am trying to install Nagios XI in a RHEL7 and have used yum for installing all pre-requisites.

I manually downloaded the following RPMs and performed a manual local install:

> sudo yum localinstall <rpm-file>
wget http://mirror.centos.org/centos/7/os/x8 ... noarch.rpm
wget http://mirror.centos.org/centos/7/os/x8 ... noarch.rpm
wget http://mirror.centos.org/centos/7/os/x8 ... x86_64.rpm
wget http://mirror.centos.org/centos/7/os/x8 ... x86_64.rpm
wget http://mirror.centos.org/centos/7/os/x8 ... noarch.rpm
wget http://mirror.centos.org/centos/7/os/x8 ... x86_64.rpm
wget http://mirror.centos.org/centos/7/os/x8 ... x86_64.rpm
wget http://mirror.centos.org/centos/7/os/x8 ... x86_64.rpm

Then using SUDO I proceed to do the full installation and got the following error on the install.log file:

Can someone point me out what needs be done to get this solved?

Thx!/Fco

Are you doing this as an offline installation? I ask because our installer takes care of all pre-reqs in an online environment and manually installing them can cause issues.

Nop, I am installing in an online system. Thanks for responding.

I would recommend following our documentation, instead of trying install prereqs separately...

http://assets.nagios.com/downloads/nagi ... ctions.pdf

If this fails, post the entire "install.log".

Could you post a bit more (like the last 50 or so lines) from the log, or better yet, attach the whole log?
