【已解决】Mac本地用supervisor和gunicorn启动和管理Flask的app

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:
【已解决】Mac本地用supervisor去管理gunicorn的Python3的Flask
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))

# 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:

l          '-'

t          date of the request
r          status line (e.g. ``GET / HTTP/1.1``)
s          status
b          response length or '-'

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

;  - 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 ".

;files = relative/directory/*.ini

[program:robotDemo]
;command=/Users/crifan/.local/share/virtualenvs/xxxRobotDemoServer-SCpLPEyZ/bin/gunicorn -c gunicorn_config.py app:app

stderr_logfile_maxbytes=2MB
stderr_logfile_backups=10
然后正常运行方法是:
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
