Re: [CentOS] Cluster Failover Troubleshooting (luci and ricci)
by Ryan Bunce 06 Jul '11

Ljubomir Ljubojevic wrote: I never installed or used any Conga/lucci/ricci sistem. But as far as I know and understand, you need to have a way for server failing to warn the rest of the nodes. Your log said it failed. Some of the failover sistems need separate network connected to collective file systems. So when eth0 is not working, main node will use eth1(2,3,4) to report this event to all other nodes. What comes to mind is that IP's set for interconnection (in lucci conf) must not be public IP's but of that separate/secundary network in order for main node to be able to contact the rest of the nodes. I hope this helps. Ljubomir Ljubomir, Thank you for your reply. I do have a secondary NIC providing the communication between the cluster nodes. I set this up by creating host entries in the /etc/hosts file and pointing those entries to the IP addresses assigned to the NIC's connected via x-over cable. I then created the cluster using the names specified in the hosts file. I've done some network sniffing on the NIC's connected with x-over cable and there's clearly a constant communication between the two boxes. This leads me to conclude that the cluster communication is both working and moving over the channel I intended. Thanks for the input. Let me know if you have any other suggestions. Ryan

Rsyslog5 and CentOS
by Dirk 06 Jul '11

06 Jul '11

Hi folks, I am in the process of getting rsyslog 5.8.2 to work on CentOS 5.6 (both 64 and 32 bit). All that is left is getting SELinux to work with it. Has anybody out there gone through the process of working this out and can provide a policy file? If not, is anyone interested in the work I will do then (is there some place to publish those files?)? Best regards, Dirk

When CentOS 6 arrives ...

What is the best way to install CentOS 6? Is there an upgrade facility from CentOS-5.6? If so, how does this compare with a clean installation? -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland

Agreed, I was doing this in a test environment, and did review the rules created. Hopefully that part was assumed ;) but if not I agree it is wise to review the policy file it creates before they get snapped it. Aly Sent from my BlackBerry device on the Rogers Wireless Network

Not sure exactly what you need but I came across this when setting up rsyslog to work with mysql and was having SELinux protecting services. This is what I used you can see if it helps resolve your issue. Again I don't know if this will work for you but u can try it in a test environment and see if it helps # setenforce 0 # service rsyslog restart # cat /var/log/audit/audit.log | grep rsyslogd | audit2allow -M myselinuxmod; semodule -i myselinuxmod.pp # setenforce 1 # service rsyslog restart That should get all audit related errors, audit allow a policy file and load up the file. Tweak it as u see fit, HTH Aly Sent from my BlackBerry device on the Rogers Wireless Network

Bind97
by listmail 06 Jul '11

06 Jul '11

I notice that CentOS 5.6 release notes say that bind97 is now included. However, my CentOS 5.6 installations have bind 9.3. I'm guessing that bind97 is not installed by default, due to the possibility of config file breakage or something. It looks like you have to explicitly install the bind97* packages. I don't see anything in the release notes about how to handle the transition from bind 9.3 to bind 9.7. Has anyone done this, or seen a list of potential pitfalls? Thanks, --Bill

Same here, I just recently started using/testing rsyslogd (to mysql [native mysql support is great])+LogAnalyzer web front end for a central log host. So far its been working quite well. Worth checking out Aly Sent from my BlackBerry device on the Rogers Wireless Network

Log monitoring
by Fajar Priyanto 06 Jul '11

06 Jul '11

Hi all, Currently I do 'tail -f /var/log/messages | grep something' to monitor/tune in my iptables rules. Based on your experience, is there any tools do that better like: - color - grepping multiple keywords - some statistic Thank you Fajar.
