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。
1. 安装
# 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。
