openstack - OpenStack HA 配置问题缺少文件

Question

根据https://www.golinuxcloud.com/configure-haproxy-in-openstack-high-availability/尝试实施 HA 的教程。我被困在需要向我没有的 /etc/httpd/conf.d/15-horizo​​n_vhost.conf 文件添加 VIP 别名的步骤。有谁知道我必须把这个放在哪里？我在 Stein 版本上工作。

Answer 1

OpenStack 的 HA 实现过程非常简单。您需要在负载均衡器机器上设置 VIP，并使用集群工具（如 keepalived 或起搏器）管理 VIP，这样您就拥有了启动和运行 haproxy 的 VIP。实际上，您可以跳过该部分并使用下面的内容进行 haproxy 配置。

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
