执行重启命令

sudo supervisorctl start demo
demo: ERROR (abnormal termination)

uwsgi.log 可能是重启的时候 uwsgi 进程仍在监听该端口

probably another instance of uWSGI is running on the same address (127.0.0.1:8001).
bind(): Address already in use [core/socket.c line 769]

我的配置文件 uwsgi.ini

不知道怎么重启的时候关掉 uwsgi 进行监控， 官方文档只有推荐用 Circus

[indust]

stopsignal=QUIT

[zonghua]

@indust http://uwsgi-docs.readthedocs.org/en/latest/Options.html?highlight=pidfile#stop 感觉不需要 supervisor 了， uwsgi 本身就有一个主从的守护进程。

[refraction]

这报错信息实在是 哈哈哈哈

[zonghua]

@refraction 有分享一下配置文件吗

[refraction]

@zonghua 啊？回复错人了吧

[clino]

看不出是什么原因导致的 master 进程挂掉

'执行重启命令

sudo supervisorctl start demo'
然而这个并不是重启命令,重启是 restart

我经常加的 supervisor 参数有这两个,你试试看有木有用:
stopsignal=QUIT
exitcodes=0,1,2 //根据你的情况改

另外直接用 uwsgi 自己跑试试看有没有 master 会挂掉的问题? 如果 uwsgi 单独跑不会出问题,但是用 supervisor 跑有问题,考虑和 supervisor 的参数有没有关系.

[zonghua]

@clino 我先 stop 了，然后再 start 的。嗯，我试一下用关闭信号。

[clino]

@zonghua 如果你先 stop 还这么提示 说明要么没真正停止,要么变僵尸进程了
