1. LUA编译安装以及Systemd开发包：
   curl -R -O http://www.lua.org/ftp/lua-5.3.5.tar.gz
yum install readline-devel
tar zxvf lua-5.3.5.tar.gz
cd lua-5.3.5
make linux
make INSTALL_TOP=/usr/local/lua install
yum install systemd-devel
2. 下载haproxy
   wget https://www.haproxy.org/download/2.0/src/haproxy-2.0.1.tar.gz
3. 解压安装
   tar zxvf haproxy-2.0.1.tar.gz
cd haproxy
make -j $(nproc) TARGET=linux-glibc USE_OPENSSL=1 USE_ZLIB=1 USE_LUA=1 LUA_LIB=/usr/local/lua/lib/ LUA_INC=/usr/local/lua/include/ USE_PCRE=1 USE_SYSTEMD=1
   make install PREFIX=/usr/local/haproxy
4. 创建运行账户
   useradd haproxy -s /sbin/nologin

检查是否支持SSL：

ldd haproxy | grep ssl
libssl.so.10 => /usr/lib64/libssl.so.10 (0x00007f1f1625f000)
