Nagios Support Forum

hi,

I am having problem while installing Nagios xi 2011R1 in my dedicated server (centos with parallel small business panel). i executed the ./fullinstall of Nagiosxi and when it starts, it ask for mysql root previlages by giving prompt to enter password. I have tried giving my plesk admin password but its showing everytime password failed. i can able to login into mysql using admin and password (using to login in plesk). but why nagios unable to take it.

I know that by default plesk disables the mysql root username. root access is gained using admin and plesk admin password. they why does the nagios installtion wont accept same password.

Does nagios installtion looking for specific root account to be active and with its password. if so they how i enable to root @localhost which is disabled by plesk...

pls help with elaborated steps.

Awaiting patiently.

regards,
John britto

Nagios xi will not install properly if you have other applications pre-installed on your system (mysql, gnome, etc.)

Important: Nagios Enterprises highly recommends and will only support installing Nagios xi on a newly installed, "clean" system.

Please, read our installation instructions here:

http://library.nagios.com/library/produ ... -nagios-xi

fine.. i have downloaded the nagiosxi vmware image and braught a static ip.

I changed the dns for my subdomain to point to the new static IP. the problem is i unable to access nagiosxi from internet. my server is with 1&1 and my domain is with dot register.

can you pls help in configuring.. and let me know what i am missing in settings.

You'll probably need to set up port forwarding with your router or firewall so that you get redirected to the xi machine properly. Port 80 traffic to your external IP address or DNS name needs to get forwarded to the internal IP of the xi server.

can u pls give me an example of port forwarding.. and where i need to do it .. i have disabled the server internal firewall. and rely on 1&1 hosting physical firewall. my server ip is (78.208.98.x) and i have set the static ip (74.208.246.x) in nagiosxi VM. i could'nt able to ping to my server from nagios VM. but when setting nagiosxi VM network in DHCP.. i can able to ping to my server.

This isn't really a Nagios question, but something you might want to look up documentation or support for on for your router. You should be able to log into your router and set rules for Port Forwarding. You want to forward traffic on port 80 to the internal IP of your xi server.

I have a 1&1 hosting dedicated server (Linux Centos 5.x with Plesk) (IP 74.208.98.x) and I configured a Nagiosxi virtual machine to run in NAT mode under VMware player 4.0. because I was unable to use bridge mode (where the 1&1's security system sees MAC spoofing from virtual machine and terminates my server network and make it offline). The only possibility I can use is the NAT mode.

Problem: I want to know how I can communicate with the nagiosxi VM behind NAT from the Public Network. Do i need to do port forwarding in VMware Nat config file which is in /etc/vmware/vmnet8/nat/nat.conf. (EX: 8080 = <VM's IP>:80 ). i did that but still i could'nt able to access nagiosxi web ui from http://<server IP>:8080. Is that i need to configure any firewall setting in my server ? i have disabled the internal firewall and using firewall from plesk SMB. there i have created a rule as follow

port =8080

source ip= any

Destination ip= VM's IP..

But still i unable to access nagiosxi webui from public network. i can able to access nagiosxi web ui in my host web browser with VM's IP . pls tell me what else i need to configure to get access Nagiosxi web UI from public network (Internet)
