Then we need some high availability environment which can easily manage with single server failure. This article will help you to install HAProxy on CentOS, RHEL servers and will configure a Layer 4 Load Balancing ( ).
Which will balance load and transfer requests to different-2 servers based on IP address and port numbers. Step 1 – Install HAProxy HAProxy package is available under default yum repository for CentOS, Redhat systems.

Dennison case company serial numbers. Daemon nbproc 1 # Number of processing cores.
After using your configuration i am getting this error in haproxy service # systemctl status haproxy.service ● haproxy.service – SYSV: HA-Proxy is a TCP/HTTP reverse proxy which is particularly suited for high availability environments. Can this solution be used to support failover for non-http processes? All we want to achieve is an automatic failover from hosta to hostb if there is a problem with hosta. A very simplistic failover. The app uses a network drive to store its configuration files,etc. So the hostb can take over with minimal disruption (users can wait upto a minute or so, but the transition needs to be automatic). I was thinking of using a virtual IP address configured on both hosts and a simple script to start the app on hostb when hosta is down.

Thanks in Advance. Hi, If you are thinking about that you add 2 hosts but only one host serve requests continuously and second host keep as spare. In any case first host goes down, then second take place of them. This you can do by adding hosta as active and hostb as backup. Configuration looks like below listen httpweb 192.168.10.10:80 mode http balance source option httpchk option forwardfor server hosta 192.168.10.100:80 weight 1 maxconn 512 check server hostb 192.168.10.101:80 weight 1 maxconn 512 check backup Also you can use this configuration for non http requests.
