OpenStack HA Configuration problem missing file

Question

according to the tutorial at https://www.golinuxcloud.com/configure-haproxy-in-openstack-high-availability/ trying to implement HA. I'm stuck at the step where I need to add a VIP alias to the /etc/httpd/conf.d/15-horizon_vhost.conf file that I don't have. Does anyone know where I have to put this? I work on the Stein edition.

Answer 1

The process of HA implementation for OpenStack is quite simple. you need to setup a VIP on your loadbalancer machines and manage the VIP with a clustering tool like keepalived or pacemaker, so you have VIP where you have your haproxy up and running. actually you can skip that part and use something like below for haproxy config.

global
  chroot  /var/lib/haproxy
  daemon
  group  haproxy
  maxconn  4000
  pidfile  /var/run/haproxy.pid
  user  haproxy

defaults
  log  global
  maxconn  4000
  option  redispatch
  retries  3
  timeout  http-request 10s
  timeout  queue 1m
  timeout  connect 10s
  timeout  client 1m
  timeout  server 1m
  timeout  check 10s
