[求助] Python Flask 部署时 supervisor 配置出现问题，不能正常运行，需要 dalao 们指点迷津，谢谢！

[环境] ：centos+supervisor+gunicorn+flask

在 /www/blog 目录下，运行是正常的

/www/blog/venv/bin/gunicorn -b 0.0.0.0:5000 -w 4 microblog:app

[状态] ：添加到 supervisor 配置中却一直重复在 running

$ supervisorctl status
microblog      RUNNING    pid 12499, uptime 0:00:02

[配置] 如下：

[supervisord]
http_port=/var/tmp/supervisor.sock ; (default is to run a UNIX domain socket server)
logfile=/var/log/supervisor/supervisord.log ; (main log file;default $CWD/supervisord.log)
logfile_maxbytes=50MB       ; (max main logfile bytes b4 rotation;default 50MB)
logfile_backups=10          ; (num of main logfile rotation backups;default 10)
loglevel=info               ; (logging level;default info; others: debug,warn)
pidfile=/var/run/supervisord.pid ; (supervisord pidfile;default supervisord.pid)
nodaemon=false              ; (start in foreground if true;default false)
minfds=1024                 ; (min. avail startup file descriptors;default 1024)
minprocs=200                ; (min. avail process descriptors;default 200)
[supervisorctl]
serverurl=unix:///var/tmp/supervisor.sock ; use a unix:// URL  for a unix socket
[program:microblog]
command=/www/blog/venv/bin/gunicorn -b 0.0.0.0:5000 -w 4 microblog:app
directory=/www/blog

log?

我无法理解你的问题。

sinazl 3楼

开 ssh，让我上去看看

songsunli 4楼

日志贴出来

不是和 venv 有关系？

wuwangju 6楼

没 log 我只能等 dalao 来 review 你的配置了…

eggper 7楼

话说 running 不是运行中的意思吗？是网站打不开还是

gougou168 8楼

兄弟你用了 venv 你环境变量却没设置啊

wuwangju 9楼

不用用 root 去跑非系统程序，不用用 root 去跑非系统程序，不用用 root 去跑非系统程序……
ps: supervisor 官网文档了解一下？

sinazl 10楼

running 有啥问题啊…… running 是正常运行中

caililin 11楼

/var/tmp 下的日志是空的。。。
小哥，怎么联系。。。
我也觉得是很 venv 有关系，但是我添加了环境变量了，在 venv 在没有进入 venv 的情况下能正常使用。。。在 venv/bin/activate 跟 /etc/profile 都添加了 export FLASK_APP=microblog.py 会不会是这个有误？
running 几秒钟就重复 start，running，block。。。

bupafengyu 12楼

是的，老哥，的确是不要在 root 下跑非系统程序。。。

wuwangju 13楼

这个其实不会执行 active 脚本的，所以我感觉修改 active 脚本没有用处的。
我感觉不行就是得给 supervisor 的 program 配置中加入 environment=PATH="/www/blog/venv/bin" 这样环境配置试试

zlyuanteng 14楼

program: microblog
里面可以加环境变量
加的是 VIRTUAL_ENV
你仔细看看 venv/bin/activate
都干了啥

vueper 15楼

所有的 Python venv 方案都要改 VIRTUAL_ENV 环境变量

日志找到了。。。原来我看错了，是在 logfile=/var/log/supervisor/supervisord.log

用 pyenv 隔离一套 python 环境，保证 python，venv，程序目录和 supervisor 在同一用户下，这是算是最理想的部署环境。

搞定，mark 一下，走人。

多谢老哥帮助！！！
其实是跟老哥你的想法一致，也跟上面的各位 dalao 想法一致的。
我把老哥解决方法说一下，以便后面的同学能及时处理这个问题。

原话：
原因是 venv 跟 gunicorn 必须是同一个 shell 引导，否则无法继承环境变量。

解决方法：
 # cat /etc/supervisord.conf [supervisord] http_port=/var/tmp/supervisor.sock ; (default is to run a UNIX domain socket server) logfile=/var/log/supervisor/supervisord.log ; (main log file;default $CWD/supervisord.log) logfile_maxbytes=50MB ; (max main logfile bytes b4 rotation;default 50MB) logfile_backups=10 ; (num of main logfile rotation backups;default 10) loglevel=info ; (logging level;default info; others: debug,warn) pidfile=/var/run/supervisord.pid ; (supervisord pidfile;default supervisord.pid) nodaemon=false ; (start in foreground if true;default false) minfds=1024 ; (min. avail startup file descriptors;default 1024) minprocs=200 ; (min. avail process descriptors;default 200) [supervisorctl] serverurl=unix:///var/tmp/supervisor.sock ; use a unix:// URL for a unix socket [program:microblog] command=/www/blog/venv/bin/gunicorn_start directory=/www/blog user=root autostart=true autorestart=true stopasgroup=true killasgrouv=true stdout_logfile=/www/blog/logs/microblog.log redirect_stderr=true # cat /www/blog/venv/bin/gunicorn_start #!/bin/sh export FLASK_APP=<a target="_blank" href="http://microblog.py" rel="nofollow noopener">microblog.py</a> cd /www/blog/ source venv/bin/activate /www/blog/venv/bin/gunicorn -b localhost:3000 -w 4 microblog:app 
直接通过一个 sh 脚本处理同一个 shell 引导，
这个时候由 gunicorn 启动的 microblog 应用服务器现在运行在本地端口 3000，
然后我再设置一下 Nginx 就可以将应用程序暴露给外部世界。
