centos6.5 64位下haproxy安装配置与使用例子

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.rootop.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

global
    log 127.0.0.1 local0 info
    maxconn 1000
    chroot /usr/local/haproxy
    uid nobody
    gid nobody
    daemon
    nbproc 1
    pidfile /tmp/haproxy.pid

    maxconn 20480
    timeout connect 5000
    timeout client 50000
    timeout server 50000
    timeout check 2000
 
    stats enable

    balance roundrobin
    option httpchk HEAD /index.html HTTP/1.0
    cookie SERVERID insert indirect
    server WEBSRV1 10.10.10.5:80 maxconn 1500 cookie SRV1 check inter 2000 rise 2 fall 3 weight 1
    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=$(ps 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

然后通过多个客户端访问haproxy的ip地址可以看到后端不同服务器提供的内容。

cookie SERVERID insert indirect  其中这句设置了会话保持，通过插入cookie方式，测试效果。

访问到服务器1：

访问到服务器2：

浏览器关闭后，会话断开。
