HAProxy日志配置

HAProxy日志配置

HAProxy能够基于rsyslog记录日志到指定的设备

日志的配置方法

1.修改haproxy配置文件

[root@localhost ~]# vim /etc/haproxy/haproxy.cfg 
log 127.0.0.1 local3 info  #在全局配置段中配置，定义日志记录级别

2.修改syslog的配置文件

[root@localhost ~]# vim /etc/rsyslog.conf 
# Provides UDP syslog reception
$ModLoad imudp              #日志传输基于udp因此须要开启
$UDPServerRun 514           #这里两项
local3.*                                                /var/log/haproxy.log

3.重启haproxy和rsyslog服务

[root@localhost ~]# systemctl restart haproxy rsyslog

4.配置HAPronxy

listen web
 bind 172.20.27.20:80
 mode http
 rspadd x-via:\ haproxy
 rspdel Server:.*
 cookie SERVER-COOKIE insert indirect nocache
 log global             #配置记录日志
 option forwardfor
 server web1 192.168.27.21:80 cookie web1 check inter 3000 fall 3 rise 5
 server web2 192.168.27.22:80 cookie web2 check inter 3000 fall 3 rise 5

5.经过浏览器访问后，查看日志

[root@localhost ~]# tail -f /var/log/messages 
Jun  5 21:04:50 localhost haproxy[23428]: Connect from 172.20.136.96:50376 to 172.20.27.20:80 (web/HTTP)
Jun  5 21:04:50 localhost haproxy[23428]: Connect from 172.20.136.96:50377 to 172.20.27.20:80 (web/HTTP)

haproxy默认的日志过于简单，也能够自定日志进行修改
