[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
user=root
autostart=true
autorestart=true

不是和 venv 有关系？

没 log 我只能等 dalao 来 review 你的配置了..

话说 running 不是运行中的意思吗？是网站打不开还是

兄弟你用了 venv 你环境变量却没设置啊

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？

running 有啥问题啊…… running 是正常运行中

2018-06-29 17:20:33 +08:00

@ericls @0xABCD @yylucifer /var/tmp 下的日志是空的。。。
@defunct9 小哥，怎么联系。。。
@knktc @tempdban 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？
@summerwar @bolide2005 running 几秒钟就重复 start，running，block。。。

Pooc

2018-06-29 17:22:48 +08:00

@robinlovemaggie 是的，老哥，的确是不要在 root 下跑非系统程序。。。

2018-06-29 17:42:02 +08:00

@Pooc 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

tempdban

2018-06-29 17:47:52 +08:00 via Android

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

tempdban

2018-06-29 17:49:01 +08:00 via Android

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。

@defunct9 多谢老哥帮助！！！
其实是跟 @robinlovemaggie 老哥你的想法一致，也跟上面的各位 dalao 想法一致的。
我把 @defunct9 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。

@defunct9 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=microblog.py

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。
