Practical Load Balancing presents an entire analytical framework to increase performance not just of one machine, but of your entire infrastructure. For a real setup, your servers should run the web server or load balancer of your choice. Conclusion Congratulations! The IP for the cluster is mandatory, and don't configure the cluster IP outside of the haresources file!.
However, this case won't fit everybody and that's why the option's there!

For Red Hat, I put the following command at the bottom of the /etc/rc.d/rc.sysinit file: /sbin/insmod softdog For the rc.local method, just put the same line right above where you This will allow us a simple way to demonstrate that the HA setup is working. This will be accomplished by pointing a Floating IP, which is how your users will access your services or website, to point to the primary, or active, server unless a failure keepalive 2 Sets the time between heartbeats to 2 seconds.

To avoid any problems, shut down heartbeat on the first node, then test your null modem cable. Please visit this page to clear all LQ-related cookies.
Volker's HA Hardware Guide and the Serial HOWTO are two good resources for troubleshooting your serial connection. https://books.google.com/books?id=cXWhU_Wj-RwC&pg=PA204&lpg=PA204&dq=error+cannot+open+key+file+/etc/ha.d/authkeys+.+stop&source=bl&ots=OUOJNKFN-O&sig=F4XVN3AeNE8IUFCrLSoeR9f-EdI&hl=en&sa=X&ved=0ahUKEwidz4foyf7PAhWCvBoK Once it's started, evenrestarts shouldn't make this happen.-- Alan Robertsonemail@example.com 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 In this case, that would be your null modem cable or serial port. 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.
Introduction to Linux - A Hands on Guide This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started Check This Out You can obtain the same information in a less verbose form from "netstat -nr" If it looks good, make sure you can ping between both nodes on all interfaces. We'll use vi:
also more thing it is require second NIC & null modem cable? However, this heartbeat needs one or more media paths between the nodes. Check /usr/src/linux/.config for "CONFIG_IP_ALIAS=y" if you don't have it, you'll have the line "CONFIG_IP_ALIAS is not set". Source curl: (7) Failed to connect to example.com port 80: Connection refused Droplet: secondary, IP Address: 18.104.22.168 Droplet: secondary, IP Address: 22.214.171.124 ...
If it happens but takes more like 30 seconds, something is wrong. Get the latest tutorials on SysAdmin and open source topics. Once you've started heartbeat, take a peek at your log file (default is /var/log/ha-log) before testing it.
If the network is insecure, but you're either not very paranoid or concerned about minimizing CPU resources, use md5. To specify a subnet with 32 addresses, you could define the service as (leaving off the IPaddr because we can!): linuxha1 192.168.85.3/27 httpd smb This sets the IP service address Create authkeys File The authorization key is used to allow cluster members to join a cluster. To do this, first type "insmod softdog" to load the module.
If you're reading this, you already have it, but in any case it's available at: http://linux-ha.org/download Untar it into your favorite source directory. You'll see how to account for persistence and state, and how you can judge the performance of scheduling algorithms. First, check your serial heartbeat. have a peek here It tries to select the lowest cost route to the IP address to be taken over.
Start Heartbeat Now that Heartbeat is configured, and all of the scripts it relies on are set up, we're ready to start the Heartbeat cluster! Read on to see how heartbeat treats this...
