前面的的文章中，我已经将环境准备好了，现在需要是ngnix做负载均衡

ngnix在centos环境环境下，我直接用yum安装，修改配置文件参照

http {    # ... 省略其它配置    upstream tomcats {        server 192.168.0.100:8080;        server 192.168.0.101:8080;        server example.com:8080;    }    server {        listen 80;        location / {            PRoxy_pass http://tomcats;        }    }    # ... 省略其它配置}修改好以后启动即可。
首先遇见的第一个问题
docker registry push错误“server gave HTTP response to HTTPS client”
解决办法   在客户端修改/etc/sysconfig/docker 加上
ADD_REGISTRY='--add-registry 192.168.174.128:5000'
INSECURE_REGISTRY='--insecure-registry 192.168.174.128:5000'
参考 http://blog.csdn.net/dream_broken/article/details/52757386
如果找到那个配置文件，参考 http://www.CUOXin.com/hobinly/p/6110624.html
再次push 的时候出现  错误
TLS handshake error from 127.0.0.1:46038: tls: first record does not look like a TLS handshake
解决办法  注释掉 tls
