Question

我正在使用HAProxy进行负载平衡。一切都运行正常，然后突然HAProxy停止运行。

/etc/haproxy/haproxy.cfg

global
        log 127.0.0.1 local2
        chroot /var/lib/haproxy
        user haproxy

        stats socket /tmp/haproxy

        server Hostname10 10.1.10.26:6351 check inter 10000 rise 5 fall 5

日志中没有显示任何内容。突然记录停止了，最后几行显示了这一点;

当我做hatop -s /tmp/haproxy时我得到的只是socket error: [Errno 111] Connection refused

我不知道该怎么调试呢。需要帮助。

“ hatop -s”是指您在/etc/haproxy/haproxy.cfg中定义的套接字要运行hatop，请按照以下配置中的说明运行“ hatop -s /var/run/haproxy.sock”。

    global
    log 127.0.0.1   local2
    maxconn 10000
    user haproxy
    group haproxy
    stats socket /var/run/haproxy.sock mode 600 level admin
    stats timeout 2m

您的代码应具有

    global
    log 127.0.0.1   local2
    maxconn 10000
    user haproxy
    group haproxy
    stats socket /tmp/haproxy mode 600 level admin
    stats timeout 2m

HAProxy开始突然拒绝连接
