Haproxy for redis slaves

[balakec]

We are using node_redis client to access the redis at present. I need
to use HAProxy in front of redis slaves which in my case is 3 nos. I
installed the HAProxy and configured it to load balance the redis
slaves. But when I tried to create connection from the node_redis
client to the HAProxy I was not able to create the connection and was
getting a error

Error: Redis reply parser error: Error: Protocol error, got "H" as
reply type byte
at HiredisReplyParser.execute (/home/user1/doosra/node-exp/
node_modules/redis/lib/parser/hiredis.js:32:31)
at RedisClient.on_data (/home/user1/doosra/node-exp/node_modules/redis/
index.js:440:27)
at Socket.<anonymous> (/home/user1/doosra/node-exp/node_modules/redis/
index.js:70:14)
at Socket.emit (events.js:67:17)
at TCP.onread (net.js:347:14)


Can anyone say the reason and wat can be done from the node redis
client side.

That *sounds* like a HAProxy configuration issue - maybe using an http-aware processor instead of a raw binary one? I'm not a HAProxy expert, but I know something very similar messed up my web-socket server until the right HAProxy config (i.e. one without any http knowledge) was used.

Hi,
Looks like you are in the HTTP mode(level 7) on haproxy instead of the tcp mode(level 4) you need to connect to redis

Try changing the haproxy.cfg to replace
        mode    http
with
mode tcp
