一直使用haproxy-1.4版本代理, 不支持ssl配置，haproxy-1.5版本支持，于是更新了版本进行测试。所使用的证书文件，使用原apache ssl证书文件进行简单处理可以在haproyx上使用。
本来想使用haproxy-1.4的穿透的，但是要后端服务器均要配置ssl，于是配置在了Haproyx-1.5上，实现ssl终端CA认证。本文出自:http://koumm.blog.51cto.com

# yum install pcre-devel openssl-devel -y
# tar zxvf haproxy-1.5.3.tar.gz
# cd haproxy-1.5.3
# make TARGET=linux26 USE_STATIC_PCRE=1 USE_REGPARM=1 USE_LINUX_TPROXY=1 USE_OPENSSL=1 USE_ZLIB=1 ARCH=x86_64
# make install PREFIX=/usr/local/haproxy
# cd /usr/local/haproxy
# mkdir conf

2. 准备pem证书文件
之前有配置过apache ssl CA认证配置文件，cer文件与key文件，pem文件就是将前面两个文件合并使用。
# cat my-server.cer my-server.key | tee my-server.pem

4. 配置要点
由于证书采用2048长度配置，默认配置文件会报错，加上tune.ssl.default-dh-param 2048参数后，问题解决，采用pem格式的证书还可以通过haproxy-1.4+stunnel方式实现ssl功能。
