HAproxy配置指令简单总结之一

进程管理及安全相关的参数
chroot
pidfile
user
uid
group
gid
log <address> <facility>
daemon

性能调整相关的参数
maxconn
noepoll
nopoll

debug相关参数
debug

balance --> roundrobin static-rr leastconn source uri uri-param hdr(<name>)
bind
mode
hash-type
map-based --> 取模 用key的hash值对server总数取模,
consistent --> 一致性hash
一致性hash算法除了计算key的hash值外,还会计算每个server对应的hash值,
然后将这些hash值映射到一个有限的值域上(比如0~2^32)
