场景：测试HAproxy服务的TCP代理服务，与nginx的TCP代理做性能对比
部署过程：
1、下载haproxy-1.8.0.zip，下载页面https://github.com/haproxy/haproxy/tree/v1.8.0
2、安装部署haproxy
unzip haproxy-1.8.0.zip
cdhaproxy-1.8.0
make TARGET=linux26 ARCH=X86_64 PREFIX=/home/homework/haproxy
make install PREFIX=/home/homework/haproxy
cd /home/homework/haproxy
mkdir etc logs
cd etc
vim haproxy.cfg
----------配置文件---------------

server s1 192.168.8.63:8887 weight 1
-------------------------------------------------------------------
chown homework.homework -R /home/homework/haproxy/
3、开启日志接收
vim /etc/rsyslog.conf
下面两行注释去掉
$ModLoad imudp
$UDPServerRun 514
添加配置
local3.* /home/homework/haproxy/logs/access.log
vim /etc/sysconfig/rsyslog
SYSLOGD_OPTIONS="-c 5"修改为下面配置
SYSLOGD_OPTIONS="-r -m 0 -c 2"
/etc/init.d/rsyslog restart
4、启动haproxy
/home/homework/haproxy/sbin/haproxy -f /home/homework/haproxy/etc/haproxy.cfg
5、检查haproxy日志是否有输出
tail /home/homework/haproxy/logs/access.log
Dec 4 10:38:50 localhost haproxy[96612]: Proxy stats started.
Dec 4 10:38:50 localhost haproxy[96612]: Proxy stats started.
至此服务部署完成、重启服务的脚本自行创建，这里就不贴出来了。
