Error Cannot Open Key File /etc/ha.d/authkeys . Stop


arief I follow your tutorial but i have a strange result. If in your implementation more nodes are participating please specify a ll the nodes.Step4 : Edit haresources file#vi /etc/ha.d/haresourcesStep4(a) : Just specify below entry in last line of this file on so change the permissions of the file to 600 on both the nodes..Two lines are required in the authkeys file:A line which says which key to use in signing outgoing packets. You'll then learn how to avoid performance degradation and any risk of the sudden disappearance of a service on a server. http://megavoid.net/error-cannot/error-cannot-open-source-file-mpi-h.html

If you try and start it as non-root then this will happen. chmod 600 /etc/ha.d/authkeys 3. In my cluster only two nodes are participating (rp1 and rp2) so just specify that entries. nice_failback on Optional. why not find out more

Is it ok? Heartbeat requires that each node name matches their respective uname -n output. It tries to select the lowest cost route to the IP address to be taken over. If your log is clean, great.

If I stop it on node2 still the clusterIP not accessible from node1. You can read Practical Load Balancing from end to end or out of sequence, and indeed, if there are individual topics that interest you, you can pick up this book and We will install Nginx on both Droplets and replace their index pages with information that uniquely identifies them. It should be at least twice the normal deadtime.Udpport : This is the port used by heartbeat to send heartbeat packet/signals to other nodes to check availability(here in this example I

i installed two node heartbeat-2.1.4-9.el5.i386.rpm with three files 1. MAY BE THAT WILL BE MORE USEFULL TO YOU..AND THANKS FOR WRITING TO LINUXNIX.COM Anonymous Thanks Surender for timely response. Step4(a) : Just specify below entry in last line of this file on node1 rp1.linuxnix.com squid Step4(b) : Just specify below entry in last line of this file on node1 http://marc.info/?l=linux-ha-dev&m=101429780411627&w=2 We'll use the public interface of our Droplets, which happens to be eth0.

Finally, for crc, a sample can be: auth 2 1 crc Make sure its permissions are safe, like 600. PASIVE WILL GET UP WHEN PASIVE IS NOT RECEIVING HEARTBEAT PULSE FROM ACTIVE NODE(THROUGH ETH1). I have configured a 2-node cluster as per the steps and everything looks good. Configuring Authkeys The third file to configure determines your authentication keys.

Error Cannot Open Key File /etc/ha.d/authkeys . Stop You may use any network interface, as long as each node can reach the other nodes in the cluster. Accessing either Droplet via its public IP address will show a basic webpage with the Droplet hostname and IP address, which will be useful for testing which Droplet the Floating IP

I HAVE TWO NODES.. The "work" I am contributing is mostly compiling bits and pieces from other HA documents (such as Volker Wiegand's Hardware Installation Guide) into a document that can help novices get started The example domain name we'll use is example.com. weblink authkeys. 2.ha.cf 3.haresources .

However, in this tutorial, we will demonstrate how to create a 2-node HA server setup by simply using Heartbeat and a DigitalOcean Floating IP.

This script will also allow you to manipulate the netmask and broadcast address of this IP service. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. Kennedy CenterAlbert Einstein College of Medicine of Yeshiva University Alan Robertson 2002-02-21 13:22:32 UTC PermalinkRaw Message Post by Maurice VolaskiHere's the error message I told you about when I saw you If your heartbeat runs over a secure network, such as the crossover cable in our example, you'll want to use crc.

But when I stop it on node2, though node1 show eth0:0 it is not picking up. If we cause the primary server to fail, by powering it off or stopping the Heartbeat service, we will see if the Floating IP gets reassigned to the secondary server. Of course, since you're looking into HA, you'll mostly likely want to avoid having only one point of failure. check over here One more thing how to say the setup is configured as Active-Active OR Active-Passive?

ONCE NODE1 IS UP NODE TWO WILL CONSIDER THE CONFIG IN THIS STEP4 TO CHECK TO HOW TO TRANSFER THE CONTROL.. The components of a cluster are commonly, but not always, connected to each other through fast local area networks. This virtual IP is used to nullify the effect of nodes going down. To check your configuration, type: ifconfig This will show your network interfaces and their configuration.

Let's power off the primary server now. Create assign-ip Script For our example, we'll download a basic Python script that assigns a Floating IP to a given Droplet ID, using the DigitalOcean API. Can you be more info.. I Can't ping virtual IP address from outside and I have search in google but nothing.

Do i change rp1.linuxnix.com squid to rp1.linuxnix.com httpd ?
