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

[uwsgi]
# Django-related settings
chdir           = /home/www/Documents/demo
module          = demo.wsgi:application
env             = DJANGO_SETTINGS_MODULE=demo.settings_production
home            = /home/www/Documents/demo/venv
user            = www
uid             = www
pcre-jit
thunder-lock
enable-threads
master          = true
touch-reload    = /home/www/Documents/demo/reload
processes       = 4
socket          = 127.0.0.1:8001
chmod-socket    = 664
vacuum          = true

supervios conf

[program:vblue]
directory= /home/www/Documents/demo
command = /home/www/Documents/demo/venv/bin/uwsgi --ini /home/www/Documents/demo/uwsgi.ini
autostart=true

redirect_stderr = true
stdout_logfile = /home/www/Documents/demo/logs/out.log
stdout_logfile_maxbytes = 1MB
stderr_logfile= /home/www/Documents/demo/logs/err.log

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 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。

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.

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

@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
