I was looking for a solution for graceful reload of haproxy. I have a nginx server running which passes requests to Haproxy and at times I reload the Haproxy configuration. But I am observing that at time of reloading all the existing connections are getting cut off and haproxy backend queue shows 0 requests ( got from socket stats of haproxy ) .
Multiple vulnerabilities have been found in HAProxy, allowing attackers to execute arbitrary code or cause Denial of Service. HAProxy is a free, very fast and reliable solution offering high availability, load balancing, and proxying for TCP and HTTP-based applications.
I am new to HA Proxy and Upstart Scripting. I am using, HA Proxy version 1.4.18 2011/09/16. I am trying to write an upstart script that will keep haproxy alive in case haproxy dies. This is what I have so far:
if [ $(pgrep haproxy) ]; then
I am setting up HAProxy to load balance between two web servers. Some of the pages on the site require SSL. Stunnel is handling the https connections and passing them off to haproxy (Stunnel contains the cert). HAProxy will hand off requests to the web servers using http. Will containing the web servers and haproxy in an internal network be enough to be PCI compliant?
