NagiosXI installation issues

[thanigaivel.a]

we are trying to do an fresh installation of NagiosXI with the latest version, however we are getting errors.

so kindly check the attached installation logs and provide the solution.

[mcapra]

Please add the 'Optional' channel to your Red Hat systems subscriptions. You can do so in the Redhat Network web interface or using the rhn-channel command. Or, install the yum-utils package and use the following command:

Code: Select all

yum-config-manager --enable rhel-7-server-optional-rpms

You also seem to have DNS errors:

Code: Select all

"Could not resolve host: repo.nagios.com; Unknown error"

Is this machine in an offline environment? There are specific steps to take when installing Nagios XI in an offline environment:

I also notice this machine is behind a proxy. There are specific configuration steps to be made when installing Nagios XI behind a proxy:

@thanigaivel.a , Let us know if the previous answer helped you resolve the problem?

[thanigaivel.a]

I've resolved the repo issues, and tried again but still problem persists

I'm expecting quick resolution on this.

please let me know if you could support via cisco webex ?

[thanigaivel.a]

can you let me know the exact resolution time

[bheden]

@thanigaivel.a,

In no particular order, I'll try and answer the questions to the best of my abilities:

can you let me know the exact resolution time

Not quite yet. We'll need more information first.

please let me know if you could support via cisco webex ?

Only when we decide that is the necessary route to take. We may be able to go get you going before that becomes a possibility.

And the question from the initial response:

Is this an offline installation?

Are you in fact behind a proxy? Did you complete the steps required in the document(s) linked to by @mcapra?

I'd like the output of the following commands:

Code: Select all

ping repo.nagios.com
ping localhost
hostname
cat /etc/hosts
cat /etc/yum.conf
cat /etc/wgetrc

Thanks.

# This is the default, if you make this bigger yum won't see if the metadata
# is newer on the remote and so you'll "gain" the bandwidth of not having to
# download the new metadata and "pay" for it by yum not having correct
# information.
# It is esp. important, to have correct metadata, for distributions like
# Fedora which don't keep old packages around. If you don't like this checking
# interupting your command line usage, it's much better to have something
# manually check the metadata once an hour (yum-updatesd will do this).

###
### Sample Wget initialization file .wgetrc
###

## You can use this file to change the default behaviour of wget or to
## avoid having to type many many command-line options. This file does
## not contain a comprehensive list of commands -- look at the manual
## to find out what you can put into this file.
##
## Wget initialization file can reside in /etc/wgetrc
## (global, for all users) or $HOME/.wgetrc (for a single user).
##
## To use the settings in this file, you will have to uncomment them,
## as well as change them, in most cases, as the values on the
## commented-out lines are the default values (e.g. "off").


##
## Global settings (useful for setting up in /etc/wgetrc).
## Think well before you change them, since they may reduce wget's
## functionality, and make it behave contrary to the documentation:
##

# You can set retrieve quota for beginners by specifying a value
# optionally followed by 'K' (kilobytes) or 'M' (megabytes). The
# default quota is unlimited.
#quota = inf

# You can lower (or raise) the default number of retries when
# downloading a file (default is 20).
#tries = 20

# Lowering the maximum depth of the recursive retrieval is handy to
# prevent newbies from going too "deep" when they unwittingly start
# the recursive retrieval. The default is 5.
#reclevel = 5

# By default Wget uses "passive FTP" transfer where the client
# initiates the data connection to the server rather than the other
# way around. That is required on systems behind NAT where the client
# computer cannot be easily reached from the Internet. However, some
# firewalls software explicitly supports active FTP and in fact has
# problems supporting passive transfer. If you are in such
# environment, use "passive_ftp = off" to revert to active FTP.
#passive_ftp = off

# The "wait" command below makes Wget wait between every connection.
# If, instead, you want Wget to wait only between retries of failed
# downloads, set waitretry to maximum number of seconds to wait (Wget
# will use "linear backoff", waiting 1 second after the first failure
# on a file, 2 seconds after the second failure, etc. up to this max).
#waitretry = 10


##
## Local settings (for a user to set in his $HOME/.wgetrc). It is
## *highly* undesirable to put these settings in the global file, since
## they are potentially dangerous to "normal" users.
##
## Even when setting up your own ~/.wgetrc, you should know what you
## are doing before doing so.
##

# Set this to on to use timestamping by default:
#timestamping = off

# It is a good idea to make Wget send your email address in a `From:'
# header with your request (so that server administrators can contact
# you in case of errors). Wget does *not* send `From:' by default.
#header = From: Your Name <[email protected]>

# You can set up other headers, like Accept-Language. Accept-Language
# is *not* sent by default.
#header = Accept-Language: en

# You can set the default proxies for Wget to use for http, https, and ftp.
# They will override the value in the environment.
#https_proxy = http://proxy.yoyodyne.com:18023/
#http_proxy = http://proxy.yoyodyne.com:18023/
#ftp_proxy = http://proxy.yoyodyne.com:18023/
https_proxy=http://www2.mc.xerox.com:8000
http_proxy=http://www2.mc.xerox.com:8000

# If you do not want to use proxy at all, set this to off.
#use_proxy = on

# You can customize the retrieval outlook. Valid options are default,
# binary, mega and micro.
#dot_style = default

# Setting this to off makes Wget not download /robots.txt. Be sure to
# know *exactly* what /robots.txt is and how it is used before changing
# the default!
#robots = on

# It can be useful to make Wget wait between connections. Set this to
# the number of seconds you want Wget to wait.
#wait = 0

# You can force creating directory structure, even if a single is being
# retrieved, by setting this to on.
#dirstruct = off

# You can turn on recursive retrieving by default (don't do this if
# you are not sure you know what it means) by setting this to on.
#recursive = off

# To always back up file X as X.orig before converting its links (due
# to -k / --convert-links / convert_links = on having been specified),
# set this variable to on:
#backup_converted = off

# To have Wget follow FTP links from HTML files by default, set this
# to on:
#follow_ftp = off

# To try ipv6 addresses first:
#prefer-family = IPv6

# Set default IRI support state
#iri = off

# Force the default system encoding
#locale = UTF-8

# Force the default remote server encoding
#remoteencoding = UTF-8

FYI, I'm able to wget repo.nagios.com, regarding "ping repo.nagios.com" hope you have disabled icmp traffic.

In this article
https://support.nagios.com/kb/article.php?id=147

You missed a very important steps

In /etc/wgetrc

Code: Select all

no_proxy=localhost,127.0.0.0/8,10.0.0.0/8,172.16.0.0/12,192.168.0.0/16 # Hosts to exclude from proxying

Add that and then re-run the install

[scottwilkerson]

May we conclude that you no longer need help here because you performed this install?
https://support.nagios.com/forum/viewto ... 3&p=246416

You still will need to perform the step above on the new machine if a proxy is configured
