HAProxy config

Setting up HAProxy

We need to specify TCP frontend and backend. It's important to turn off logging. Otherwise, it would flood the disk. Also, it should only use cores #2 and #3:

global
    # disable logging
    log /dev/log    local0 warning alert 
    log /dev/log    local1 warning alert
    chroot /var/lib/haproxy
    stats socket /run/haproxy/admin.sock mode 660 level admin expose-fd listeners
    stats timeout 30s
    user haproxy
    group haproxy
    # stick to cores 2 and 3
    nbproc 2
    cpu-map 1 2
    cpu-map 2 3
    daemon


frontend rserve_frontend
    bind *:8999
    mode tcp
    timeout client  1m
    default_backend rserve_backend

backend rserve_backend
    mode tcp
    option log-health-checks
    log global
    balance roundrobin
    timeout connect 10s
    timeout server 1m
    server rserve1 localhost:80
