当linux设备上开启sonar6.2时，

supervisorctl status报如下错误:

error: <class ‘xml.parsers.expat.ExpatError‘>, syntax error: line 1, column 0: file: /usr/local/lib/python2.7/xmlrpclib.py line: 557

关闭sonar6.2时，报如下错误：

error: <class ‘socket.error‘>, [Errno 113] No route to host: file: /usr/local/lib/python2.7/socket.py line: 571

据说要关闭防火墙

/usr/sbin/sestatus查看防护墙状态

cat /etc/selinux/config查看防火墙配置

SELINUX=disabled关闭

原来是这两行注释掉了

[inet_http_server]         ; inet (TCP) server disabled by default
port=*:9002

tmd，supervisor.conf的配置太坑了，不小心就会出错

error: <class 'xml.parsers.expat.ExpatError'>, syntax error: line 1, column 0: file: /usr/local/lib/python2.7/xmlrpclib.py line: 557
