supervisor
守护进程，用这个的原因实在是因为scrapyd太脆弱了，一看不住就挂了
安装:
sudo pip install supervisor
配置:
sudo mkdir -p /etc/supervisor/
＃导入默认配置
sudo su - root -c "echo_supervisord_conf > /etc/supervisor/supervisord.conf"
#链接管理
[inet_http_server] ; inet (TCP) server disabled by default
port=127.0.0.1:9001 ; (ip_address:port specifier, *:port for all iface)
;username=user ; (default is no username (open server))
;password=123 ; (default is no password (open server))
[supervisorctl]
;serverurl=unix:///tmp/supervisor.sock ; use a unix:// URL for a unix socket
serverurl=http://127.0.0.1:9001 ; use an http:// url to specify an inet socket
