openstack部署haproxy

在所有节点安装Haproxy

第一步：安装haproxy

yum -y install haproxy
systemctl enable haproxy.service

第二步：所有节点配置haproxy

cat <<EOF>/etc/rsyslog.d/haproxy.conf
$ModLoad imudp
$UDPServerRun 514
$template Haproxy,"%msg%n"
local0.=info -/var/log/haproxy.log;Haproxy
local0.notice -/var/log/haproxy-status.log;Haproxy
local0.* ~
EOF

systemctl restart rsyslog.service
systemctl status rsyslog.service
