Haproxy编译安装

实验环境：

本次安装使用的主机是Rocky 8，安装的haproxy版本为3.0.8，更多源码包下载地址：http://www.haproxy.org/download/

编译lua环境：

yum -y install gcc openssl-devel pcre-devel systemd-devel make
wget http://www.lua.org/ftp/lua-5.4.7.tar.gz
tar xf lua-5.4.7.tar.gz -C /opt
cd /opt/lua-5.4.7/
make all test

编译安装haproxy：

# 下载源码包
wget https://www.haproxy.org/download/3.0/src/haproxy-3.0.8.tar.gz
tar xf haproxy-3.0.8.tar.gz -C /usr/local/src
cd /usr/local/src/haproxy-3.0.8/
 
# 参考INSTALL文件进行编译安装
