Getting error in Nagios XI

[rlinux57]

I have getting below error while installing Nagios XI on my lxd container centos6.8 (4.4.0-64-generic)

Code: Select all

Any update ?

Our hours are 9am - 5pm Mon - Thurs and 9am - 2pm Fridays (CST) hence the delayed response.

Was this a clean, minimal install of this OS?
(refer to the XI Installation Prerequisites here
https://assets.nagios.com/downloads/nag ... ctions.pdf
The step that is failing, this updates the iptables config on the system. The following will skip the step of modifying the firewall/iptables. Is the install successfull when you run this:

Code: Select all

touch installed.firewall
./fullinstall

[rlinux57]

I think its a minimal os.
Now its working but getting another error below:

I followed this thread https://support.nagios.com/forum/viewto ... f=6&t=7617 , now i am getting different error:

Can you share the output of the following commands executed from the CLI of your Nagios XI machine:

Code: Select all

yum clean all
yum install httpd
rpm -qa | grep http

Can you also try running the fullinstall script after those steps?

[rlinux57]

Below are the output of following command, still same error after running given commands:

Code: Select all

[root@exotic-owl ~]# yum clean all

It looks as if this machine is unable to resolve the CentOS repository hosts:

Code: Select all

Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=os&infra=stock error was
14: PYCURL ERROR 6 - "Couldn't resolve host 'mirrorlist.centos.org'"

That is likely the root of your problems. Is this machine in an offline environment? We have offline repositories for such a setup, though they should only be used if this machine has no internet access:
http://repo.nagios.com/

Otherwise, you'll probably need to change your system's network settings or resolv.conf to properly resolve the various CentOS repository mirrors.
