    这是一个创建于 2340 天前的主题，其中的信息可能已经有所发展或是发生改变。

    [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
stopasgroup=true
killasgroup=true

    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……

    @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 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

    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

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

    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。
