NRPE on 64bit Linux OS

32 or 64bit?

64 bit

VMware Image or Manual Install of XI?

Are there specials configurations on your system, ie; is Gnome installed? Are you using a proxy? Are you using SSL?

No.

Issue

In order to get the NagiosXi to fully install on a Red Hat 6 64bit OS, we had to do the following (please see the attachment). According to Red Hat support, php-common 32bit is not supported and will not work on a 64bit Red Hat OS. Was there something I missed in the initial instructions, for installing NagiosXi manually on to a 64bit Linux OS? Are there any additional steps needed to get NagiosXi running smoothly on a 64bit Linux OS?

Thank you for your time,
Eddie

I'm not exactly sure how or why you would be getting 32 bit versions of anything on your machines, we have test builds that run several times a day on clean RHEL 64bit machines and haven't seen any problems like this...

Perfect! That's all I needed to hear, for now. I have to bring this up to our Linux Admin that brought up this question.

Thanks!

The install for NagiosXi works just fine; However, when we go do a "yum update" we get errors due to it downloading 32bit versions of files. I believe it's because on one of the install files "0-yum" it asks if you have a "el5", but not a "el6" 64bit. We are running Red Hat 6 64bit, not Red Hat 5 64bit.

0-yum

if [ "$dist $arch" = "el5 x86_64" ]; then
if [ "$INTERACTIVE" != False ]; then
cat <<-EOF

if [ "$res" != "y" ]; then

fi

echo "64-bit system detected, modifying yum"
cat >>/etc/yum.conf <<-EOF

# Modifications by Nagios XI installer
multilib_policy=best

EOF

if rpm -q librsvg2.i386 >/dev/null; then
yum -y remove librsvg2.i386
fi
yum -y remove \*.i?86
fi

Following the above, there maybe some other scripts in the install process to update to include the

if [ "$dist $arch" = "el5 x86_64" ]; then

Did we hit gold with this one?

Thanks for looking into this, as I believe others would experience the same on RH6_64bit.... maybe?

What this is doing is removing 32 bit packages that are pre-installed in some el5 machines.

They aren't preinstalled on el6 machines so there is no need to check for them....
