Nagios XI installation.

[dtuser]

nagiosxi page is showing db corrupted. Running the repair script would not fix the issue. postgresql is showing no nagios db. Could someone help me in fixing this? Thanks.

Is this a fresh installation? If so you should probably just redownload and start from scratch. The install process is near foolproof.

We can look at your install.log for issues if you attach it, however in the time you wait for us to analyse the log you probably could have reinstalled it and had it working.

Initial installation failed many times due to not finding "optional RHN channel." Even if I bypassed 0-yum step it was giving me error. So, for every step it gave me error, I bypassed by creating that file to bypass a particular step.

I did have optional channel enabled.

# rhn-channel -l
lab-ss-rhel6-custom-x86_64-server
lab-ss-rhel6-rhn-tools-server
lab-ss-rhel6-x86_64-server
lab-ss-rhel6-x86_64-server-optional

That's a pretty reliable way to cause a fullinstall to fail. Since you appear to be using local repos, you might be best services using the offline installation. It's also important that your mirrors are kept fairly current.

If I'm wrong and those are public mirrors - I recommend starting over and instead of bypassing installation steps, post the install.log when it fails and we can try to help you troubleshoot.

What should be the password at this step?

No idea. We don't require any passwords to install Nagios, you simply need root access. Anywhere that you're getting a password prompt is specific to your environment. Do you have an authenticating http proxy that your yum is potentially trying to use?

I'm not sure.

It prompted for password after installing a few packages. After failed attempts of passwords, it continued as -

Installing : nagiosxi-nagiosmobile-4-2.7.el6.x86_64 56/57
Installing : nagiosxi-4-2.7.el6.x86_64 57/57

Verifying : nagiosxi-nagiosmobile-4-2.7.el6.x86_64

then after a few more packages, it showed completed -

python-rrdtool.x86_64 0:1.4.7-1.el6.rfx unixODBC.x86_64 0:2.2.14-14.el6

Complete!

I restarted httpd. http://<server>/nagiosxi still showed corrupted database. I'm getting a new server image. Will do a clean install afterwards. Thanks.

That's probably best, the install process truly is a no brainer.

./fullinstall

walk away for 15 minutes and get coffee

come back to XI installed.

It sounds like you are offline, is that true? If so then definitely go the route suggested with the offline installer. Also, are your RHEL images custom deployed? If so they may have some proxy settings we need to fiddle with.

If you haven't already blasted it, the install log may have some useful data. For offline installs it has some sensible name like xi_install.log or something and is in the /tmp directory. For online installs it's just install.log in the untarred install directory.

I did an offline install on a clean image. It's working now. Thanks for your help.
