原因

uwsgi 启动时，找不到正确的python引起。

原来是机器上原来有一个默认的uwsgi　

root@standby.me [14:10:38]$ uwsgi --version
2.0.16
root@standby.me [14:10:45]$ which uwsgi
/usr/sbin/uwsgi
root@standby.me [14:10:49]$
root@standby.me [14:10:34]$ /usr/local/python2.7/bin/uwsgi --version
2.0.17
root@standby.me [14:10:45]$

原来启动是：

killall -9 uwsgi && uwsgi --ini /data/app/hcdnstatistics/run/uwsgi.ini

改为正确的uwsgi即可

/usr/local/python2.7/bin/uwsgi --ini /data/app/hcdnstatistics/run/uwsgi.ini
