Installation instruction for XI on CentOS 7?

[Box293]

It seems like I do have some issue, that only started after rebooting the server. All my services are shown 4 times in the XI gui. In the CCM they are only visible once. What could cause this?

Yeah I've noticed this recently too while playing with XI builds on CentOS 7. Always occurs after a system boot and as soon as you restart the monitoring engine everything is OK.

It's easy to reproduce:

• Install CentOS 7 with Minimal Build
  Install latest version of Nagios

Thanks Troy for the tip. Restarting the monitoring engine does indeed help. I didn't test yet if the issue re-appears when the server is rebooted.
I do seem to have another small issue. All actions I perform seem to fail. Check the attached screenshot for the complete error. Now the good thing is that these actions that seem to fail are in fact executed correctly. The server does not have a really high load or is not extremely busy. Did anyone see this before?
Is there yet a bug report for the quadruple services?

For what it's worth, I am unable to replicate the x4 display bug on a fresh install of XI on CentOS 7 I just set up today. I've rebooted it twice now attempting to get this to happen and haven't had any luck.

Are you on 2.6 or 2.7?

Also, my CentOS version:

Code: Select all

I'll try this with an updated CentOS build and let you know if I can reproduce it.

It could maybe also be the PHP version?

➜  ~  php -v
PHP 5.4.16 (cli) (built: Jun 23 2015 21:17:27)

I have the same version on my machine.

Can you please also test to "schedule immediate forced check" and see if you get the same error message as me? (see previous post)

That worked, however, upon reboot of the 7.1 machine I was able to replicate the 4x bug.

Hmm. Seems I'm unable to apply configuration anymore since i changed the nagiosxi.conf

2015-08-11 19:47:06 ERROR 403: Forbidden. clearly is the issue and related to the change in /etc/httpd/conf.d/nagiosxi.conf I did to try secure the nagiosxi instance.

Anyone knows what I can do allow Nagios XI to apply configuration while keeping the deny from all and allow from config in /etc/httpd/conf.d/nagiosxi.conf ?

Code: Select all

<Directory "/usr/local/nagiosxi/html">
#  SSLRequireSSL
   Options None
   AllowOverride None
#   Order allow,deny
#   Allow from all
  Order deny,allow
  Deny from all
  Allow from 102.22.50.45 102.22.37.130 102.27.33.70 127.0.0.1 222.71.234.84 2a01:fe00::f43c:91ff:fe18:6141
#   AuthName "Nagios XI"
#   AuthType Basic
#   AuthUserFile /usr/local/nagiosxi/etc/htpasswd.users
#   Require valid-user
   Require all granted
</Directory>

Alias /nagiosxi "/usr/local/nagiosxi/html"

I added localhost 127.0.0.1, the server's own ipv4, ipv6 link and global address, so it should be allowed to access itself? When I revert to the normal (non-secure) situation it works normally.
