1、安装haproxy
# yum install -y haproxy
# systemctl enable haproxy.service
2、配置haproxy日志
[root@controller1 ~]# cd /etc/rsyslog.d/
[root@controller1 rsyslog.d]# vim haproxy.conf
$ModLoad imudp
$UDPServerRun 514
$template Haproxy,"%msg%"
local0.=info -/var/log/haproxy.log;Haproxy
local0.notice -/var/log/haproxy-status.log;Haproxy
local0.* ~
[root@controller1 ~]# scp /etc/rsyslog.d/haproxy.conf controller2:/etc/rsyslog.d/
haproxy.conf 100% 164 0.2KB/s 00:00
[root@controller1 ~]# scp /etc/rsyslog.d/haproxy.conf controller3:/etc/rsyslog.d/
启动rsyslog
[root@controller1 ~]# systemctl restart rsyslog.service
[root@controller1 ~]# systemctl status rsyslog.service
配置haproxy
[root@controller1 ~]# vim /etc/haproxy/haproxy.cfg
