一、HAProxy 配置

HAProxy 日志采用默认配置：

cat /etc/haproxy/haproxy.cfg

global
        log /dev/log    local0
        log /dev/log    local1 notice

注意：


  • 日志的 level：local0～local7，16～23保留为本地使用，其中：
  • 0：emerg，系统不可用；
  • 1：alert，必须马上采取行动的事件；
  • 2：crit，关键的事件；
  • 3：err，错误事件；
  • 4：warning，警告事件；
  • 5：notice，普通但重要的事件；
  • 6：info，有用的信息；
  • 7：debug，调试信息。

二、修改 /etc/rsyslog.d/49-haproxy.conf

原文件如下：

haproxy配置日志log haproxy 日志_IP


注释红线部分，并在其下面添加：

$ModLoad imudp
$UDPServerRun 514

$template haproxylog,"/root/haproxy/logs/haproxy-%$year%-%$month%-%$day%.log"
#template(name="haproxylog" type="string" string="/root/haproxy/logs/haproxy-%$year%-%$month%-%$day%.log")

$template logformat,"%TIMESTAMP:8:15%.%timestamp:::date-subseconds% %syslogtag% %msg%\n"

if $programname startswith 'haproxy' then ?haproxylog; logformat

&~

注意：


$IncludeConfig /etc/rsyslog.d/*.conf

  • 所以，如果我们要自定义某个服务的日志，最好在 /etc/rsyslog.d/ 目录下创建相应的文件，而不是直接修改 /etc/rsyslog.conf。



重启 rsyslog 与 HAProxy：

systemctl restart rsyslog
systemctl restart haproxy

查看日志文件：

haproxy配置日志log haproxy 日志_ci_02

三、设置日志内容格式

HAProxy 默认日志比较杂乱，字段含义也比较难懂。

haproxy配置日志log haproxy 日志_IP_03


可使用 log-format，对格式进行自定义：

listen  proxy_tw
        bind :16001
        option tcplog
        mode tcp
        balance roundrobin
        server tw_proxy_1 192.168.255.128:22121 check inter 10s
        server tw_proxy_2 192.168.177.128:22121 check inter 10s

        log    global
        option logasap
        log-format client:%ci:%cp\ frontend:%fi:%fp(%f)\ backend:%bi:%bp(%b)\ real_server:%si:%sp(%s)\ status_code:%ST\ retries:%rc\ termination_state:%ts


listen  proxy_web
        bind :16002
        mode http
        balance roundrobin
        #option forwardfor
        timeout server 15s
        timeout connect 15s
        #option httpclose
        option  redispatch

        log    global
        option logasap
        log-format client:%ci:%cp\ URI:/%HU\ frontend:%fi:%fp(%f)\ backend:%bi:%bp(%b)\ real_server:%si:%sp(%s)\ status_code:%ST\ http_request:%r\ retries:%rc\ termination_state:%ts

        server web_proxy_1 192.168.255.128:8571 check inter 10s
        server web_proxy_2 192.168.255.128:8572 check inter 10s
        server web_proxy_3 192.168.177.128:8571 check inter 10s
        server web_proxy_4 192.168.177.128:8572 check inter 10s

haproxy配置日志log haproxy 日志_IP_04


注意：




  • 日志中可能缺少某些数据；
  • 连接关闭时，不会写日志；
  • 日志格式：
