我刚刚在我的Debian系统上安装了HaProxy 1.6,我想用它来分发WebSocket(WS://)连接。系统正在运行同一WebSocket服务的5个服务器实例;这些实例具有相同的IP地址但具有不同的端口:
192.168.10.1:801
192.168.10.1:802
192.168.10.1:803
192.168.10.1:804
192.168.10.1:805
我正在寻找一些建议来创建一个简单的配置文件来侦听端口800上的请求并在服务器之间平均分配(可能是?)。
defaults
mode http
# Set timeouts to your needs
timeout client 5s
timeout connect 5s
timeout server 5s
frontend all 0.0.0.0:800
mode http
timeout client 120s
option forwardfor
# Fake connection:close, required in this setup.
option http-server-close
option http-pretend-keepalive
acl is_sockjs path_beg /echo /broadcast /close
acl is_stats path_beg /stats
use_backend sockjs if is_sockjs
use_backend stats if is_stats
default_backend static
backend sockjs
# Load-balance according to hash created from first two
# directories in url path. For example requests going to /1/
# should be handled by single server (assuming resource prefix is
# one-level deep, like "/echo").
balance uri depth 2
timeout server 120s
server srv_sockjs1 127.0.0.1:12345
# server srv_sockjs2 127.0.0.1:9998
backend static
balance roundrobin
server srv_static 127.0.0.1:801
backend stats
stats uri /stats
stats enable
我设法通过使用上面已经下载的配置文件以某种方式使其工作..但它看起来太复杂了我,并且一次只接受一个连接。如果第二个客户端连接,则HA代理断开前一个/第一个,并连接一个新的/第二个..
答案 0 :(得分:1)
最简单的方法是为所有的websocket机器定义一个后端,并围绕它们进行循环,如下所示:
frontend ft_web
bind 192.168.10.1:800 name http
maxconn 10000
default_backend bk_web
backend bk_web
balance roundrobin
server websrv1 192.168.10.1:801 maxconn 10000 weight 10 cookie websrv1 check
server websrv2 192.168.10.1:802 maxconn 10000 weight 10 cookie websrv2 check
...
如果它没有用,似乎你的超时时间太短,试着像这样定义它们:(默认情况下)
timeout client 25s
timeout connect 5s
timeout server 25s
# timeout tunnel available in ALOHA 5.5 or HAProxy 1.5-dev10 and higher
timeout tunnel 3600s
timeout http-keep-alive 1s
timeout http-request 15s
timeout queue 30s
timeout tarpit 60s
