supervisord停止子进程 [英] supervisord stopping child processes

问题描述

一个问题，我面对supervisord是，当我有一个命令这反过来又产生另一个过程，supervisord无法杀死它。

One of the problems, I face with supervisord is that when I have a command which in turn spawns another process, supervisord is not able to kill it.

例如我有一个正常运行的时候就像

For example I have a java process which when runs normally is like

 $ zkServer.sh start-foreground
 $ ps -eaf | grep zk
 user 30404 28280  0 09:21 pts/2    00:00:00 bash zkServer.sh start-foreground
 user 30413 30404 76 09:21 pts/2    00:00:10 java -Dzookeeper.something..something

该supervisord配置文件如下：

The supervisord config file looks like:

[program:zookeeper]
command=zkServer.sh start-foreground
autorestart=true
stopsignal=KILL

这样的过程具有多个孩子的不能很好supervisord当它涉及到从 supervisorctl 阻止他们处理。所以，当我运行这个从supervisord并尝试从supervisorctl停止，只有顶级的过程就会被杀死，但不是实际的Java进程。

These kind of processes which have multiple childs are not well handled by supervisord when it comes to stopping them from supervisorctl. So when I run this from the supervisord and try to stop it from supervisorctl, only the top level process gets killed but not the actual java process.

是由里克·汉龙II在这里遇到了同样的问题： HTTPS ：//$c$crwall.com/p/4tcw7w

The same problem was encountered by Rick Hanlon II here: https://coderwall.com/p/4tcw7w

选项 stopasgroup = TRUE 应在supervisord程序段被设置为停止，不仅父进程，而且子进程。

Option stopasgroup=true should be set in the program section for supervisord to stop not only the parent process but also the child processes.

的例子被给定为：

[program:some_django]
 command=python manage.py runserver
 directory=/dir/to/app
 stopasgroup=true

此外，心里有，你可能有一个旧包supervisord的不具有stopasgroup功能。
我试着树莓派这些Debian软件包：

Also, have in mind that you may have an older package of supervisord that does not have "stopasgroup" functionality. I tried these Debian packages on Raspberry Pi:

• supervisor_3.0a8不起作用。


• 如预期supervisor_3.0b2-1工作。
