安装完haproxy后默认是没有启用日志的，如果需要日志配置，那么需要结合rsyslog

修改haproxy配置

在全局配置段中配置，定义日志记录级别。

global
    log 127.0.0.1 local3  info

 

修改rsyslog配置

#日志传输基于udp，所以需要取消这两行的注释。
[root@LB ~]# sed -n '21,22p' /etc/rsyslog.conf
$ModLoad imudp
$UDPServerRun 514

#文件末尾添加
local3.*			/var/log/haproxy.log

 

[root@LB ~]# systemctl restart haproxy rsyslog

 

没什么问题后访问一下就会在/var/log/haproxy.log中看到日志

[root@LB ~]# tail -f /var/log/haproxy.log
