1.下载
https://fossies.org/linux/misc/legacy/haproxy-1.7.9.tar.gz
2.解压
将安装包上传至home目录下
cd /home
tar -zxvf haproxy-1.7.9.tar.gz
cd haproxy-1.7.9
3.安装
make TARGET=linux2628 ARCH=x86_64 PREFIX=/usr/local/haproxy
make install PREFIX=/usr/local/haproxy
#参数说明
TARGET=linux26 #内核版本，使用uname -r查看内核，如：2.6.18-371.el5，此时该参数就为linux26；内核大于2.6.28的用：TARGET=linux2628
ARCH=x86_64 #系统位数
PREFIX=/usr/local/haprpxy #/usr/local/haprpxy为haprpxy安装路径
4.创建haproxy.cfg文件
mkdir /usr/local/haproxy/etc
vi /usr/local/haproxy/etc/haproxy.cfg

5.启动&停止
启动：/usr/local/haproxy/sbin/haproxy -f /usr/local/haproxy/etc/haproxy.cfg
停止：pkill -9 haproxy
6.开启日志记录功能
首先，vi /etc/rsyslog.conf添加下面一行:

local0.* /var/log/haproxy.log

同时修改

# Provides UDP syslog reception#$ModLoad imudp#$UDPServerRun 514

为

# Provides UDP syslog reception$ModLoad imudp$UDPServerRun 514

然后，vi /etc/sysconfig/rsyslog
将SYSLOGD_OPTIONS="-c 5"改为：SYSLOGD_OPTIONS="-r -m 0 -c 2"
最后重启rsyslog&haproxy即可
service rsyslog restart
pkill -9 haprox
/usr/local/haproxy/sbin/haproxy -f /usr/local/haproxy/etc/haproxy.cfg
