Thanks for your quick response. looks like it is not switching properly… Start heartbeat on node1start heartbeat on node2observation:clusterIP on node2 is active. Heartbeat decides which interface will be used by looking at the routing table. Be sure to get the IP addresses of both servers. navigate here

The haresources will need one line: linuxha1.linux-ha.org 192.168.85.3 httpd smb So, this line dictates that on startup, have linuxha1 serve the IP 192.168.85.3 and start apache and samba as well. Advantages of Cluster :1.Reduced Cost : Its cheaper to by 10 normal servers and do cluster on them then buying a high end servers like blade servers, which will do more Note that this file is not used in a setup that uses a CRM like Pacemaker We will also need to provide a script that will perform the Floating IP reassignment http://lists.linux-ha.org/pipermail/linux-ha/2003-April/007743.html
Copy and paste this configuration into the file, then replace the respective node names and IP addresses with the values that we looked up earlier. After the Floating IP has been assigned, check that you can reach the Droplet that it was assigned to by visiting it in a web browser. For most configurations this means the default route will be least preferred.

heartbeat not started. Since this document is called "Getting Started", we'll keep it simple...... To achieve this goal, we will follow these steps: Create 2 Droplets that will receive traffic Create Floating IP and assign it to one of the Droplets Create DNS A record Before moving on, let's test that it works as intended.
Wait about 10 seconds. If this all works, you've got availability. This configures the primary server as the preferred host for the floatip service, which is currently undefined. http://marc.info/?l=linux-ha-dev&m=101429780411627&w=2 Starting and testing heartbeat From Red Hat, or other distributions which use the SystemV style init files, simply type /etc/rc.d/init.d/heartbeat start on both nodes.

What have I done wrong now, and what can I do? http://birdsallgraphics.com/error-cannot/error-cannot-open-file-c-recovery-dat.php In addition to the API, this tutorial utilizes the following DigitalOcean features: Floating IPs Metadata User Data (Cloud-Config scripts) Please read the linked tutorials if you want to learn more about you can just keep httpd then check if you have httpd script in /etc/ha.d/resource.d/ then only it will work bharat my virtual ip address is not stabling in n nodes to Anonymous ********************************/var/log/ha-log on node2 (next started): info: Heartbeat generation: 1265931585 info: glib: UDP Broadcast heartbeat started on port 694 (694) interface eth1 info: glib: UDP Broadcast heartbeat closed on port 694
In our example setup, we will name them "primary" and "secondary" for easy reference. You can even use CentOS repositories, but only for certain installs. Can anyone tell me where from I can get rpm for the above? http://birdsallgraphics.com/error-cannot/error-cannot-open-file-recovery-dat.php Once it's started, evenrestarts shouldn't make this happen.-- Alan Robertsonfirstname.lastname@example.org 1 Reply 2 Views Switch to linear view Disable enhanced parsing Permalink to this page Thread Navigation Maurice Volaski 2002-02-18 02:28:51
Do so via the DigitalOcean Control Panel or by running this command on the primary server:
Now, let's open a terminal and use curl to access the Floating IP on a 1 second loop. Heartbeat will look for startup scripts of the same name in the following paths: /etc/ha.d/resource.d /etc/rc.d/init.d These scripts must start services via "scriptname start" and stop them via "scriptname Once it's started, even restarts shouldn't make this happen. -- Alan Robertson [email protected] _______________________________________________________ Linux-HA-Dev: [email protected] http://lists.community.tummy.com/mailman/listinfo/linux-ha-dev Home Page: http://linux-ha.org/ [prev in list] [next in list] [prev in thread] [next in Hope this helps.

DO AS BELOW..1)STOP THE HEARTBEAT CLUSTER ON ACTIVE NODE.. As we configure it as auto fail back.. We will also need to look up the network interface and IP address that each node will use to communicate with the rest of the cluster, to determine which nodes are uncomment the last 4 lines in /etc/ha.d/authkeys Last edited by malayo; 03-03-2011 at 02:44 AM.

The preferred host is the node that should run the associated service(s) if the node is available. You'll also explore load balancing in the modern context of the cloud.

If one node in the cluster goes down second node will take care of serving users without interrupted service with availability of five nines i.e. 99.999%. 2.
