How to correctly set up IMPI?
I guess this one is a bit more tricky to trouble shoot, but here's what I have:
* IMPI network was set up during installation;
* cabling done;
* anything to check in BIOS?
* following QluMan guide "3.7. IPMI settings" I set "Initialize IPMI: true" in "Generic Property Set" assigned to nodes;
* nodes "Hardware Property Set" has "IPMI Adapter: true";
Rebooted everything, started "console-login", but see only headnode.
What did I miss?
I need to increase Open file limit on the nodes. Should I use customized "limits.conf" and follow admin guide "4.2.5. Adding directories, files, links"?
* soft nproc 10024
* hard nproc 10024
* soft nofile 50024
* hard nofile 50024
* soft memlock 255707144
* hard memlock 255707144
my/limits.conf /etc/security root:root 644
Is that a good way?
I would like to limit access to the cluster via hosts.allow and hosts.deny. What is the best way to do it?
I could create a script in /etc/qlustar/common/rc.boot/
that looks like this:
echo 'sshd: ALL' >> /etc/hosts.deny
echo 'sshd: localhost' >> /etc/hosts.allow
echo 'sshd: xxx.xxx.xxx.xxx' >> /etc/hosts.allow
Is that ok?
