作者：袖梨 2022-06-30

系统版本：centos6.5_x64
软件版本：haproxy-1.5.9.tar.gz
后端服务器IP：10.10.10.5、10.10.10.6

这里提供haproxy的本站下载地址：wget -c http://www.r**oo*top.org/rs/haproxy-1.5.9.tar.gz

安装：

[root@rootop-haproxy haproxy-1.5.9]# make TARGET=linux26 PREFIX=/usr/local/haproxy install

这里为什么是linux26，可以去看下README文档。

创建配置文件：

[root@rootop-haproxy ~]# mkdir /usr/local/haproxy/conf
[root@rootop-haproxy ~]# vi /usr/local/haproxy/conf/haproxy.cfg

server WEBSRV2 10.10.10.6:80 maxconn 1500 cookie SRV2 check inter 2000 rise 2 fall 3 weight 1

启动服务：

[root@rootop-haproxy ~]# /usr/local/haproxy/sbin/haproxy -f /usr/local/haproxy/conf/haproxy.cfg

stats uri /status #监控页面
stats auth admin:admin #监控页身份认证

提供一个管理脚本：

#!/bin/bash
PROXY_CONF=/usr/local/haproxy/conf/haproxy.cfg
PROXY_BIN=/usr/local/haproxy/sbin/haproxy
CHECK_PROXY=$( aux | grep "haproxy -f" | grep -v grep | wc -l)

case $1 in

start)
if [ $CHECK_PROXY -ge 1 ]; then
echo "already running , exit"
exit
else
$PROXY_BIN -f $PROXY_CONF
if [ $? == 0 ]; then
echo "start ok"
else
echo "start failed"
fi
fi
;;

stop)
kill -9 $(cat /tmp/haproxy.pid)
if [ $? == 0 ]; then
rm -f /tmp/haproxy.pid && echo "stop ok"
else
echo "stop failed"
fi
;;

restart)
kill -9 $(cat /tmp/haproxy.pid)
if [ $? == 0 ]; then
rm -f /tmp/haproxy.pid && echo "stop ok"
else
echo "stop failed"
fi

$PROXY_BIN -f $PROXY_CONF
if [ $? == 0 ]; then
echo "start ok"
else
echo "start failed"
fi
;;

*)
echo "only start/stop/restart"
esac

exit
