我已经为 haproxy 配置了三个应用服务器

haproxy.cfg：

global
    log 127.0.0.1 local2
    maxconn 10000

defaults
    log global
    log-format {"type":"haproxy","timestamp":%Ts,"http_status":%ST,"http_request":"%r","remote_addr":"%ci","bytes_read":%B,"upstream_addr":"%si","backend_name":"%b","retries":%rc,"bytes_uploaded":%U,"upstream_response_time":"%Tr","upstream_connect_time":"%Tc","session_duration":"%Tt","termination_state":"%ts"}
    mode http
    option  httplog
    option forwardfor
    option httpclose
    option accept-invalid-http-request
    option dontlognull
    option redispatch
    retries 1
    timeout http-request 40s
    timeout connect 40s
    timeout client 40s
    timeout server 40s

userlist UsersAuth
user viz-status insecure-password VIZ-STATUS

frontend hap-LB
    bind *:80
    log global
    http-request set-header X-Forwarded-Port %[dst_port]
    http-request set-header X-Forwarded-Proto https if { ssl_fc }
    http-request set-header X-Forwarded-Host %[req.hdr(Host)]
    default_backend nginx-nodes
frontend sm-viz
    bind *:8008
    default_backend sm-viz

backend nginx-nodes
    stats enable
    stats hide-version
    stats uri /hap-status
    stats realm Haproxy\ Statistics
    stats auth hap-status:HAP-STATUS
    balance roundrobin
#    option httpchk /feeds/hostname
    server dev-01 10.0.0.1:80 #check
    server dev-02 10.0.0.2:80 #check
    server dev-03 10.0.0.3:80 #check

backend sm-viz
    acl AuthOkay http_auth(UsersAuth)
    http-request auth realm Swarm-Visualizer if !AuthOkay
    balance roundrobin
    option httpchk /
    server dev-01 10.0.0.1:8081 check
    server dev-02 10.0.0.2:8081 check
    server dev-03 10.0.0.3:8081 check

配置一切正常，但我们在 /var/log/haproxy/haproxy.log 文件中每次请求获得两次日志

Mar  5 06:37:47 localhost haproxy[1]: 10.0.0.1:34380 [05/Mar/2018:06:37:47.648] hap-LB nginx-nodes/dev-01 0/6/-1/-1/10 503 212 - - SC-- 1/1/0/0/+1 0/0 "GET / HTTP/1.1"

Mar  5 06:37:48 localhost haproxy[1]: 10.0.0.3:34382 [05/Mar/2018:06:37:48.123] hap-LB nginx-nodes/dev-03 0/8/-1/-1/16 503 212 - - SC-- 1/1/0/0/+1 0/0 "GET /favicon.ico HTTP/1.1"

谁能帮我解决这个问题，为什么每个请求要存储两次日志？以及我该如何解决这个问题？

【解决方案1】：

您现在可能已经解决了它，但是为了未来的 google 人的利益 - 原因是您在 defaults 部分和 frontend 部分都有 log 指令。如果您从 frontend 部分中删除该行，您应该只会得到一个日志项。
