HAProxy提供高可用性、负载均衡以及基于TCP和HTTP应用的代 理,支持虚拟主机,它是免费、快速并且可靠的一种解决方案。
4,7层负载均衡软件Haproxy 1.5.6发布。 2014-10-19 上个版本是2014-10-09的1.5.5.
Very few fixes this time, 1.5.6 fixes the annoying bug reported this week about disabled proxies, an issue in the URI hash (the question mark of a query string was accidently hashed when present), an off-by-one when checking the stick-counter number in "track-sc" rules, resulting in the "track-sc3" action being accepted and reported as valid but ignored, and slightly improves the systemd wrapper.
完全改进:
2014/10/18 : 1.5.6 - BUG/MEDIUM: systemd: set KillMode to 'mixed' - MINOR: systemd: Check configuration before start - BUG/MEDIUM: config: avoid skipping disabled proxies - BUG/MINOR: config: do not accept more track-sc than configured - BUG/MEDIUM: backend: fix URI hash when a query string is present
