#启动supervisor服务
service supervisor start
PS:由于线上apt-get安装的supervisor默认版本都是3.0b2这个版本，而这个版本很多业务都出现过supervisorctl重启应用卡住的情况，实际上就是执行成功了，却没有返回导致卡住，所以发版的时候就会hang在那里。google了一圈基本都尝试过也没有好的办法，而升级版本是可以解决这个问题的。。
详见:

如果线上已经在用的supervisor的，可以直接用pip install -U supervisor -i http://pypi.douban.com/simple，然后把/etc/init.d/supervisor文件中的DAEMON=/usr/bin/supervisord替换成DAEMON=/usr/local/bin/supervisord，再重启supervisor服务就好了，不过这样的做法会影响线上supervisor纳管的所有应用不可用(大概10s)，所以要先和业务沟通哦^_^
