The whole configuration is done in the /etc/keepalived/keepalived. log depending on your syslog configuration) something like this: Keepalived is a network routing software, it is so closed to I/O. Keepalived provides frameworks for both load balancing and high availability. Keepalived Configuration ¶ The whole configuration is done in the /etc/keepalived/keepalived. In our case study this file on LVS director 1 looks like: Keepalived provides an SNMP subsystem that can gather various metrics about the VRRP stack and the health checker system. In this method, the Load-Balancer receives requests from users on the public network and uses network address translation (NAT) to forward those requests to the real servers Keepalived configuration synopsis ¶ The Keepalived configuration file uses the following synopsis (configuration keywords are Bold/Italic): All daemon messages are logged through the Linux syslog. . If you start Keepalived with the “dump configuration data” option, you should see in your /var/log/messages (on Debian this may be /var/log/daemon. The load balancing framework relies on the well-known and widely used Linux Virtual Server (IPVS) kernel module, which provides Layer 4 load balancing. Keepalived User Guide ¶ Introduction Software Design Load Balancing Techniques Installing Keepalived Keepalived configuration synopsis Keepalived programs synopsis IPVS Scheduling Algorithms IPVS Protocol Support Configuring SNMP Support Case Study: Healthcheck Case Study: Failover using VRRP Case Study: Mixing Healthcheck & Failover As of Red Hat 6. Therefore, run the following to install the keepalived package and all the required dependencies using YUM: Virtual Server via NAT ¶ NAT Routing is used when the Load-Balancer (or LVS Router) has two Network Interface Cards (NICs), one assigned an outside-facing IP address and the other, a private, inside-facing IP address. Keepalived provides frameworks for both load balancing and high availability. The keepalived MIB is in the doc directory of the project. You are now ready to configure the Keepalived daemon according to your LVS topology. conf file. 4, Red Hat and the clones have included the keepalived package in the base repository. The design used here is a central select () that is in charge of scheduling all internal task.
