Question

当uWSGI通过Upstart启动时，我有独立的Emperor实例，每个实例有两个进程（手动运行，见下文）。

Upstart创建多个皇帝进程：

# ps ax | grep -i emper                                                                                                                       
  888 ?        S      0:53 uwsgi /etc/uwsgi/emperor.ini
  896 ?        S      0:33 uwsgi /etc/uwsgi/emperor.ini
  904 ?        S      0:52 uwsgi /etc/uwsgi/emperor.ini
  905 ?        S      0:34 uwsgi /etc/uwsgi/emperor.ini
  ...

当我杀死所有皇帝并手动运行时，我有两个Emperor's进程，其中有工作人员用于网站：

# pstree -up | less
  ...
  -uwsgi(16347)---uwsgi(16348)-+-uwsgi(16349,web)-+-uwsgi(16358)
    |                             |                  |-uwsgi(16360)
    |                             |                  |-uwsgi(17058)
    |                             |                  |-uwsgi(17261)
    |                             |                  |-uwsgi(17410)
    |                             |                  |-uwsgi(17488)
    |                             |                  |-uwsgi(17750)
    |                             |                  `-uwsgi(17770)
    |                             `-uwsgi(16350,web)-+-uwsgi(16361)
    |                                                |-uwsgi(16362)
    |                                                |-uwsgi(16363)
    |                                                |-uwsgi(16364)
    |                                                |-uwsgi(16365)
    |                                                |-uwsgi(16366)
    |                                                |-uwsgi(16367)
    |                                                `-uwsgi(16368)

我对皇帝的Upstart配置：

# Emperor uWSGI script

description "uWSGI Emperor"
start on runlevel [2345]
stop on runlevel [06]

respawn

exec uwsgi /etc/uwsgi/emperor.ini

我的uWSGI Emperor配置：

[uwsgi]
  emperor-tyrant = true
  emperor = %dvassals
  emperor-pidfile = %demperor.pid
  emperor-stats = %demperor.stat.sock
  vassals-include = %dvassals-default.ini
  touch-logrotate = %p
  touch-reload = %p
  touch-reload = %dvassals-default.ini
  log-date = true
  log-truncate = true
  daemonize = /var/log/uwsgi/emperor.log

我可能在Upstart配置上出错了吗？日志对我没有帮助。

Answer 1

需要将daemonize更改为logto。
