HAProxy 無法啟動 SYSV

我正在嘗試啟動 ha 代理但沒有成功。這是來自 journalctl -xe 的錯誤：

這是我的 /etc/haproxy/haproxy.cfg

global
  maxconn 4096
  log /dev/log local0
  log /dev/log local1 notice
  chroot /var/lib/haproxy
  stats socket /run/haproxy/admin.sock mode 660 level admin
  stats timeout 30s
  user haproxy
  group haproxy
  daemon

defaults
  log global
  mode http
  option httplog
  option dontlognull
  retries 3
  option  redispatch
  maxconn 2000
  timeout connect 5000
  timeout client 50000
  timeout server 50000

listen swift-cluster
bind 192.168.0.91:80
   mode    http
   stats   enable
   stats   auth haproxy_username:haproxy_password
   balance roundrobin
   option  httpchk HEAD /healthcheck HTTP/1.0
   option  forwardfor
   option  http-server-close
   timeout http-keep-alive 500
   server  proxy1 192.168.0.41:80 weight 5 check inter 2000
   server  proxy2 192.168.0.42:80 weight 5 check inter 2000

我究竟做錯了什麼？

這是因為我忘記為套接字創建一個文件夾。這幫助了我：

sudo mkdir -p /run/haproxy
