折腾：
【未解决】Flask本地和线上用gunicorn和supervisor部署时如何传入环境变量
期间，已经修改了supervisor的配置，加上了环境变量的参数：
command=/Users/crifan/.local/share/virtualenvs/xxxRobotDemoServer-SCpLPEyZ/bin/gunicorn -c gunicorn_config.py FLASK_ENV=production app:app
然后再去本地Mac调试，看看
FLASK_ENV=production
能否传递到Flask中。
关于如何用supervisord启动app，先去参考自己之前的帖子：
先去确认本地Mac中已安装了supervisor：
➜ xxxRobotDemoServer git:(master) ✗ which supervisord /Users/crifan/Library/Python/2.7/bin/supervisord ➜ xxxRobotDemoServer git:(master) ✗ supervisord --version 3.3.4
然后再去启动和管理：
supervisord -c conf/supervisor/supervisord_local.conf supervisorctl status supervisorctl start all supervisorctl stop all supervisorctl restart all supervisorctl start robotDemo supervisorctl stop robotDemo supervisorctl restart robotDemo
结果出错：
【已解决】Mac中运行supervisord再运行supervisorctl出错：http://localhost:9001 refused connection
【总结】
此处Mac中，之前已安装了supervisor，
已有之前写好了gunicorn的配置：
conf/gunicorn/gunicorn_config.py
import multiprocessing
import os
import sys
# sys.path.append(".")
# from config import BaseConfig
curPath = os.path.dirname(os.path.abspath(__file__))
print("curPath=%s" % curPath)
confPath = os.path.join(curPath, "..")
print("confPath=%s" % confPath)
sys.path.append(confPath)
from conf.app import settings
print("settings=%s" % settings)
appRootPath = os.path.join(confPath, "..")
print("appRootPath=%s" % appRootPath)
#appRootPath = "/Users/crifan/dev/dev_root/company/xxx/projects/robotDemo"
# appRootPath = os.getcwd()
# print("appRootPath=%s" % appRootPath)
# flaskHost = BaseConfig.FLASK_HOST
# flaskPort = BaseConfig.FLASK_PORT
flaskHost = settings.FLASK_HOST
flaskPort = settings.FLASK_PORT
print("flaskHost=%s, flaskPort=%s" % (flaskHost, flaskPort))
reload = True #当代码改变时自动重启服务
#bind = '127.0.0.1:32851' #绑定ip和端口号
# bind = '0.0.0.0:32851' #绑定ip和端口号
bind = ("%s:%s" % (flaskHost, flaskPort))
backlog = 512 #监听队列
chdir = appRootPath #gunicorn要切换到的目的工作目录
timeout = 30 #超时
worker_class = 'sync' #默认的是sync模式
workers = multiprocessing.cpu_count() * 2 + 1 #进程数
threads = 2 #指定每个进程开启的线程数
loglevel = 'info' #日志级别，这个日志级别指的是错误日志的级别，而访问日志的级别无法设置
access_log_format = '%(t)s %(p)s %(h)s "%(r)s" %(s)s %(L)s %(b)s %(f)s" "%(a)s"' #设置gunicorn访问日志格式，错误日志无法设置
"""
其每个选项的含义如下：
h remote address

u currently '-', may be user name in future releases
t date of the request
r status line (e.g. ``GET / HTTP/1.1``)
s status
b response length or '-'
f referer
a user agent
T request time in seconds
D request time in microseconds
L request time in decimal seconds
p process ID

; Notes:
; - Shell expansion ("~" or "$HOME") is not supported. Environment

; - Quotes around values are not supported, except in the case of

; - Comments must have a leading space: "a=b ;comment" not "a=b;comment".
; - Command will be truncated if it looks like a config file comment, e.g.
; "command=bash -c 'foo ; bar'" will truncate to "command=bash -c 'foo ".

指定配置文件
supervisord -c conf/supervisor/supervisord_local.conf
即可运行，之后即可去管理：
supervisorctl status supervisorctl start all supervisorctl stop all supervisorctl restart all supervisorctl start robotDemo supervisorctl stop robotDemo supervisorctl restart robotDemo
