Nagios Installation failed on Linux server

[amane]

Hi,
we are trying to install Nagios XI on Linux server which is in inside the firewall. However Nagios installation is failing on server with few errors.


Attached the file for errors which we are getting while installing.

Is there any way to copy all required repositories on server to install nagios XI?

[ssax]

Does this server have internet access or access to the external repositories? It kind of looks like it doesn't but we can check with these commands:

Code: Select all

nmap -Pn -p80,443 repo.nagios.com
nmap -Pn -p80,443 mirrors.fedoraproject.org

Are you using the offline installer from here or the source install?

https://repo.nagios.com/?repo=offline

[amane]

Hi ssax,

Please find below output for nmap.

Also we have followed below steps to install Nagios XI on RHEL 8.2.

Manual Download
Alternatively, you can install Nagios XI by issuing the following commands in your terminal session:
cd /tmp
wget https://assets.nagios.com/downloads/nag ... est.tar.gz
tar xzf xi-latest.tar.gz
cd nagiosxi
./fullinstall


Is it required external repository access if we use offline installer from 'https://repo.nagios.com/?repo=offline'?

[ssax]

They are showing closed which is weird, usually they would say filtered if they were blocked. Do you have a web gateway/proxy/security device or anything that could be interfering with it? Please PM me the output of these commands:

Code: Select all

ping 72.14.181.71
ip a
curl -k -L -v 'https://repo.nagios.com'

If you use the offline install the system still needs access to the repositories to download packages (whether mounted via DB or by setting up your own local repositories that mirror those that it does have access to).

[ssax]

Try doing this and then run the ./fullinstall again:

Code: Select all

sudo subscription-manager repos --enable "codeready-builder-for-rhel-8-*-rpms"

If that doesn't work, send the output of this command:

Code: Select all

yum repolist all

[amane]

Thanks Ssax,

Ran the “sudo subscription-manager repos --enable "codeready-builder-for-rhel-8-*-rpms” command on server and started the installation again. However 2 errors got resolved and below three error occurred.

Error:
Problem 1: cannot install both graphviz-gd-2.40.1-40.el8.x86_64 and graphviz-g-2.40.1-39.el8.x86_64

Problem 3: package nagiosxi-shellinabox-5.7.2-1.el8.x86_64 conflicts with shelinabox provided by shellinabox-2.20-9.el8.x86_64
- conflicting requests
(try to add '--allowerasing' to command line to replace conflicting packages or'--skip-broken' to skip uninstallable packages or '--nobest' to use not only bet candidate packages)


We have moved below files to temp directory and started the installation again.
graphviz-g-2.40.1-39.el8.x86_64
snmptt-1.4-0.1.el8.noarch
shellinabox-2.20-9.el8.x86_64

Installation got completed but Nagios services are not running on the server.

Your system is trying to connect through pip to download the packages but it doesn't have access, this is why you should run the offline installer otherwise you'll need to grant access through the FW or manually install them.

Here are the domains it needs access to TCP 80/443:

Code: Select all

assets.nagios.com
api.nagios.com
repo.nagios.com
pypi.org
pypi.python.org
files.pythonhosted.org

You can download this file:

Code: Select all

https://files.pythonhosted.org/packages/fe/aa/59c7c8a2cf1ef0726cd4c64bff7072147db8cbb6b4379fb0c3d7c67331b9/pymssql-2.1.5-cp36-cp36m-manylinux1_x86_64.whl

Transfer it to the server and install it like this:

Code: Select all

pip3 install /PATH/TO/YOUR/pymssql-2.1.5-cp36-cp36m-manylinux1_x86_64.whl

[amane]

Hi Ssax,

We are using offline installer ‘nagiosxi-5.7.2-1.el8.x86_64.tar.gz’ which is downloaded from ‘https://repo.nagios.com/?repo=offline’ for installation.

Installed ‘pymssql-2.1.5-cp36-cp36m-manylinux1_x86_64.whl’ package.

[root@ lxappnagistgs06 tmp]# pip3.6 install /tmp/pymssql-2.1.5-cp36-cp36m-manylinux1_x86_64.whl WARNING: Running pip install with root privileges is generally not a good idea.

However Nagios service is still not starting on server and getting below mentioned error.

[ssax]

You will need to re-run the fullinstall after doing that, it is not installed properly so you'll need to re-run it.

You can also do this to get more information:

Download this file to your /tmp directory of your XI server:

https://repo.nagios.com/nagiosxi-offlin ... _64.tar.gz

Then as root, run these commands on your XI server:

Code: Select all

cd /tmp
rm -rf nagiosxi
tar zxf nagiosxi-5.7.2-1.el8.x86_64.tar.gz
mv nagiosxi nag
cd nag
rpm2cpio nagiosxi-5.7.2-1.el8.x86_64.rpm​ | cpio -idmv
cd tmp/nagiosxi
./rpminstall

Then send us the full output of all the commands if it fails.
