Hello to all. I'm a Linux-HA newbie. I've read several how-to's, etc., but am struggling with getting HA to work for me. I would most appreciate the community's help both in understanding how HA works, and in getting my set-up operational. Apologies for the length of my post.
As a test/learning exercise, I've installed heartbeat-2.1.3-3, heartbeat-pils-2.1.3-3, heartbeat-stonith-2.1.3-3, and heartbeat-gui-2.1.3-3 via RPM on a CentOS 4 and a CentOS 5 box. Here is other relavant information about hte two boxes: CentOS 4 - hostname=danvers (confirmed with uname -n), interface=eth0 192.168.100.12, eth0:0 192.168.103.6(IP aliased) CentOS 5 - hostname=pembroke, interface=eth1 192.168.100.6 Neither machine has a second physical interface (well, node 2 does, but it's not operational), both are on the local area network 192.168.100.0/22. Both are running, e.g. apache. All HA configuration-related files are the same on both machines. Here are the configuration-related files: ha.cf: use_logd yes keepalive 500ms deadtime 2 warntime 1 initdead 8 udpport 694 bcast eth1 node danvers node pembroke crm on haresources danvers IPaddr::192.168.103.6::httpd authkeys auth 1 1 sha1 mypassword output of crm_mon -i1: Defaulting to one-shot mode You need to have curses available at compile time to enable console mode ============ Last updated: Tue Mar 10 13:00:58 2009 Current DC: pembroke (675a48e3-3c9e-49ee-ba3c-2bf6dd107be3) 2 Nodes configured. 1 Resources configured. ============ Node: pembroke (675a48e3-3c9e-49ee-ba3c-2bf6dd107be3): online Node: danvers (aa78e7bf-db5c-49a3-a201-875e0747f149): online resource_ (lsb:httpd): Started pembroke (note: I used heartbeat_gui to create the resource, but mya have done that wrong.) I think I'm trying to failover apache. Some questions: 1. Must I have a second physical interface on each box? 2. Must I create and bring up an aliased IP on node 1? 3. Can the SHA1 password be a plain text word, or must I generate one? 4. Should this work if I simply stop httpd on danvers (node 1)? It doesn't. 5. Must httpd be running on both boxes? It seems to get shut down on danvers (node 1) when I start heartbeat on that machine. 6. Do I need to install an other software? I'll probably think of more questions right after I hit the send key. Once again, you're help is most appreciated.
