Supervisord - 运行需要与终端交互的python脚本

时间:2017-01-11 11:38:20

标签: python supervisord

我有一个python脚本,它接受键盘输入并将其输入到csv文件中。将会有许多Raspberries执行相同的任务,我想查看一个管理过程,以确保Python脚本仍在运行。

我正在查看Supervisord,它启动我的脚本并且我可以远程监视脚本 - 但是当supervisord启动python脚本时,它会阻止它与终端进行交互 - 因此脚本不会拾取任何键盘条目。有没有办法让python代码启动但与命令行交互?

PS这是编码的第一位,所以肯定是Noob!

Supervisord.conf:

; Sample supervisor config file.

; For more information on the config file, please see:

; Notes:
;  - Shell expansion ("~" or "$HOME") is not supported.  Environment
;    variables can be expanded using this syntax: "%(ENV_HOME)s".
;  - Comments must have a leading space: "a=b ;comment" not "a=b;comment".

; the below section must remain in the config file for RPC
; (supervisorctl/web interface) to work, additional interfaces may be

[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface

[supervisorctl]

; The below sample eventlistener section shows all possible
; eventlistener subsection values, create one or more 'real'
; eventlistener: sections to be able to handle event notifications
; sent by supervisor.



; The below sample group section shows all possible group values,
; create one or more 'real' group: sections to create "heterogeneous"
; process groups.

;[group:thegroupname]
;programs=progname1,progname2  ; each refers to 'x' in [program:x] definitions
;priority=999                  ; the relative start priority (default 999)

; The [include] section can just contain the "files" setting.  This
; setting can list multiple files (separated by whitespace or
; newlines).  It can also contain wildcards.  The filenames are
; interpreted as relative to this file.  Included files *cannot*
; include files themselves.

;[include]

我设法解决了 - 我想出了supervisorctl fg命令,它将进程带到前台并让我与它进行交互。

我还设法从/ etc / profile中自动启动它,以便启动supervisord进程,睡眠5,然后启动supervisorctl fb命令。
