需求
Nginx 并不支持tcp协议，所以后端的一些基于TCP的业务就只能通过其他高可用负载软件来完成了，如Haproxy。但在1.90发布后增加了tcp代理模块，而老版本nginx需通过附加module实现TCP代理

make #重要，不要make install！！！
mv /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.0719.old
cp objs/nginx/usr/local/nginx/sbin/
make upgrade
kill -USR2 `cat /usr/local/nginx/logs/nginx.pid`
这步可能出现少安装的东西 直接yum（apt-get）安装即可
nginx -t 验证一下
