supervisord日志不显示我的输出

Question

我有一个[program:x]正在运行,它打印/ sys.stdout.writes很多东西.在[supervisord]的AUTO childlogdir或[program:x]的stdout_logfile中都没有出现这些内容我错过了什么？

如何从[program:x]中捕获所有打印或stdout-ed的内容？

在我的程序中,我明确地做了两个,

print "something"
sys.stdout.write("something") 

相关的supervisord.conf文件

[supervisord]
childlogdir = %(here)s/../logs/supervisord/
logfile = %(here)s/../logs/supervisord/supervisord.log
logfile_maxbytes = 100MB
logfile_backups = 10
loglevel = info
pidfile = %(here)s/../logs/supervisord/supervisord.pid
umask = 022
nodaemon = false
nocleanup = false

[program:x]
directory = %(here)s/../
command = python file.py
autostart=true
autorestart=true
redirect_stderr=true  
stdout_logfile = /appropriate-path/to/access.log

Answer 1

您可以像这样运行您的程序:

python -u file.py

这将产生无缓冲的输出

Answer 2

Python输出是缓冲的.在您中设置环境变量PYTHONUNBUFFERED=1supervisord.conf将禁用缓冲并更快地显示日志消息:

[program:x]
environment = PYTHONUNBUFFERED=1

或者将-u命令行开关添加到python命令:

[program:x]
command = python -u file.py

或者,您可以sys.stdout显式刷新处理程序:

sys.stdout.flush()

在python 3.3及更高版本中,您可以添加flush=True参数以使该功能为您执行此操作:

print(something, flush=True)
