Question

尝试使用NGINX停止supervisord时遇到错误。

要从NGINX开始supervisord而不出错，我必须在sudo中将supervisord.conf添加到nginx命令中：

[supervisord]
[program:nginx]
command=sudo nginx -c %(ENV_PWD)s/configs/nginx.conf

当我运行时：

$ supervisord -n
2017-02-09 12:26:06,371 INFO RPC interface 'supervisor' initialized
2017-02-09 12:26:06,372 INFO RPC interface 'supervisor' initialized

2017-02-09 12:26:08,384 INFO success: nginx entered RUNNING state, process has stayed up for > than 1 seconds (startsecs)

^C # SIGINT: Should stop all processes

    os.kill(pid, signal)

使用supervisorctl停止进程时相同：

$ supervisorctl stop nginx
FAILED: unknown problem killing nginx (22321):Traceback (most recent call last):
  File "/Users/ocervell/.virtualenvs/ndc-v3.3/lib/python2.7/site-packages/supervisor/process.py", line 432, in kill

    os.kill(pid, signal)

有解决方法吗？

如果由supervisord创建的进程创建了自己的子进程，则supervisord无法杀死它们。

...

当安装了supervisor时，pidproxy程序会被放入你的配置的$ BINDIR中（它是一个“控制台脚本”）。^[1]

所以你要做的就是改变你的supervisord配置：

[program:nginx]
command=/path/to/pidproxy /path/to/nginx-pidfile sudo nginx -c %(ENV_PWD)s/configs/nginx.conf

这可能也不起作用，因为nginx进程是由sudo创建的。但是，让我们先试试吧。
