1. Director：
   //查看及安装haproxy

 1000  yum info haproxy1001  yum install haproxy -y1002  rpm -ql haproxy

//配置调度器的real server

 1003  vim /etc/haproxy/haproxy.cfg maxconn#每个进程最大并发数nbproc#启动的进程数spread -check #将其检查时间间隔增/减一随机时长     （上面三个一般默认，但可能会用到）frontend  main *:80default_backend   websrvsbackend  websrvsbalance     roundrobin #轮循server   web1   192.168.184.10:80 checkserver   web2   192.168.184.11:80 check

//启动并查看80端口

 1004  systemctl start haproxy.service1006  ss -tnl

//配置haproxy专有日志并重启rsyslog监听514端口

 1014  vim /etc/haproxy/haproxy.cfg log         127.0.0.1 local21015  vim /etc/rsyslog.conf $ModLoad imudp$UDPServerRun 514local2.*             /var/log/haproxy.log
1026  systemctl restart rsyslog.service1027  systemctl status rsyslog.service1028  ss –unl

//查看效果

 1029  curl http://192.168.184.20（多几次）

//查看selinux及iptables是否关闭

getenforce
setenforce 0
1030  iptables -F
1032  iptables -L
1035  tail /var/log/haproxy.log
