安装：
使用supervisor做进程管理，使用Nginx做反向代理；supervisor可以使用源码安装和yum安装(CentOS)，使用pip安装和源码安装是一样的道理：
sudo pip install supervisor
supervisor默认会从(/usr/local/etc/supervisord.conf, /usr/local/supervisord.conf, supervisord.conf, etc/supervisord.conf, /etc/supervisord.conf)寻找配置文件，为了方便，我们生成配置文件并修改后，链接到/etc/supervisord.conf。
生成配置文件：
echo_supervisord_conf > /a/path/etc/supervisord.conf
按示例修改，修改后链接到指定位置：
sudo ln -s /a/path/etc/chnservices.conf /etc/chnservices.conf
将Nginx配置文件修改后链接到默认位置：
sudo ln -s /a/path/etc/nginx/nginx.conf /etc/nginx/nginx.conf
使Nginx中设置的静态目录与项目的静态目录保持一致：
ln -s /a/path/chnservices /var/www/tornado
启动supervisor:
1sudo supervisord -c /etc/supervisord.conf 2sudo supervisorctl start all 3sudo supervisorctl reload all 4sudo supervisorctl restart all
此时，浏览器访问http://127.0.0.1:8001/和http://127.0.0.1:8002/应该就可以看到“Hello, world”了.
启动nginx：
sudo service nginx restart
此时，浏览器访问http://127.0.0.1:8000/就可以看到从tornado经nginx的“Hello, world”了.
添加开机启动：
tornado代码遇到异常退出时supervisor会自动重新启动我们的python代码，但是现在supervisor不是开机启动的，编辑/etc/rc.local， 在exit 0之前添加sudo supervisord即可。
