Hi im desperate on finding a solution for this. Can u help me Vivek Gite regarding this. And i dont understand it even more but i need to find it out. I was instructed by someone to look for a multiple linux configuration that has or maybe shows load balancing and failover. Or anyone who has knowledge about it coz im not even familiar with this terminology.

So restarting service manually works fine but surviving to this very little BACKUP fluctuation does not works. Suddenly, Keepalived BACKUP instance (secondary), probably for a little unresponsiveness of network connection, go in “Transition to MASTER STATE” (read from /var/log/messages), immediately see MASTER (Received higher prio advert) and goes to Backup state “Entering BACKUP STATE”. As this transition was partial (we do not see complete transition messages as when we do service restart) and/or arp advertising does not work correctly. We installed and configured Keepalived on 2 HA firewalls Virtual Machines (VMWare ESXi infrastructure). No communications take place until we restart Keepalived service on the MASTER. During this sudden transition, VIP remain only on the MASTER but communications on networks managed by MASTER are lost.

centos keepalived

Keepalived 系统环境: ***** 两台服务器都装了 CentOS-5. 2-x86_64 系统 Virtual IP.

This will also work with reverse proxy server such as nginx. If your are using a LVS director to loadbalance a server pool in a production environment, you may want to have a robust solution for healthcheck & failover. How do I install and configure Keepalived for reverse proxy server such as nginx or lighttpd. K eepalived provides a strong and robust health checking for LVS clusters. It implements a framework of health checking on multiple layers for server failover, and VRRPv2 stack to handle director failover.

I tried this guide out along with the recommended steps from the comments and it worked beautifully on my centos 5. I also verified from the Cisco switch that the ARP table changed when the backup node took over as it’s supposed to:
XXXXXX-3560g-11#sh arp | include 10.

Thank you for posting. It kind of helps but I am still getting my ass kicked. 4 machine with two NICs. I have a Centos 6.

そもそレプリケーションの構成的にどうなの?とかいう話は別として、単純にやってみたいからやってみました(笑
まず、MySQL レプリケーション(シングルMASTER – マルチSLAVE)ってすごいよね?
データベース参照負荷の高いアプリでは、SLAVEをガンガン増やして、ロードバランサー(keepalived)のvip経由でアクセスしちゃえば、簡単にスケールアウトできちゃうわけだから。仮に複数あるSLAVEサーバのうち1台が故障したとしても、他のSLAVEが生きているかぎり、簡単にロードバランサーから関連ノードを切り離してしまえば、サービスを停止することなく、データベースのメンテナンスができちゃうもんね。.
