下载软件包
haproxy-1.9.8.tar.gz

解压缩
tar -zxvf haproxy-1.9.8.tar.gz

解压后目录
/opt/haproxy/haproxy-1.9.8

安装依赖
yum install gcc pcre-static pcre-devel -y

进入文件目录-编译安装
1、cd /opt/haproxy/haproxy-1.9.8
2、make TARGET=linux2628
3、make install
4、mkdir -p /etc/haproxy
5、ln -s /usr/local/sbin/haproxy /usr/sbin/haproxy
(安装完的可之执行文件在/usr/local/sbin/haproxy，需要创建一个软连接到/usr/sbin/haproxy，因为启动脚本默认使用/usr/sbin/haproxy这个位置)

6、cp /opt/haproxy/haproxy-1.9.8/examples/haproxy.init /etc/init.d/haproxy
(把启动文件拷贝到init.d目录下)

7、chmod 755 /etc/init.d/haproxy

8、useradd -r haproxy
(添加一个账户)

9、haproxy -v
(HA-Proxy version 1.9.8 2019/05/13 - https://haproxy.org/)
