HAProxy启动时候常见问题

rabbitmq和haproxy结合时候，遇到了下面问题
某段配置：

listen rabbitmq_local_cluster 127.0.0.1:5670
    mode tcp
    balance roundrobin
    server rabbit1 127.0.0.1:5672 check inter 5000 rise 2 fall 3
    server rabbit2 127.0.0.1:5673 check inter 5000 rise 2 fall 3
    server rabbit3 127.0.0.1:5674 check inter 5000 rise 2 fall 3

listen private_monitoring :8100
    mode http
    option httplog
    stats enable
    stats uri   /stats
    stats refresh 5s

报错：

[ALERT] 167/151633 (56845) : parsing [haproxy.cfg.local_cluster:27] : 'listen' cannot handle unexpected argument '127.0.0.1:5670'.

修改为既可以

listen rabbitmq_local_cluster
    bind 127.0.0.1:5670
    mode tcp
    balance roundrobin
    server rabbit1 127.0.0.1:5672 check inter 5000 rise 2 fall 3
    server rabbit2 127.0.0.1:5673 check inter 5000 rise 2 fall 3
    server rabbit3 127.0.0.1:5674 check inter 5000 rise 2 fall 3

listen private_monitoring
    bind :8100
    mode http
    option httplog
    stats enable
    stats uri   /stats
    stats refresh 5s

重新启动【haproxy -f haproxy.cfg.local_cluster】报错:

[ALERT] 167/151959 (58789) : Starting frontend GLOBAL: cannot change UNIX socket ownership [/tmp/haproxy.socket]

改成sudo haproxy -f haproxy.cfg.local_cluster 既可以。
