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：
1 | 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：
1 2 3 4 | ➜ xxxRobotDemoServer git:(master) ✗ which supervisord/Users/crifan/Library/Python/2.7/bin/supervisord➜ xxxRobotDemoServer git:(master) ✗ supervisord --version3.3.4 |
然后再去启动和管理：
1 2 3 4 5 6 7 8 9 10 11 | supervisord -c conf/supervisor/supervisord_local.confsupervisorctl statussupervisorctl start allsupervisorctl stop allsupervisorctl restart allsupervisorctl start robotDemosupervisorctl stop robotDemosupervisorctl 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
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 | import multiprocessingimport osimport sys# sys.path.append(".")# from config import BaseConfigcurPath = 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 settingsprint("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_PORTflaskHost = settings.FLASK_HOSTflaskPort = settings.FLASK_PORTprint("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 addressl '-'u currently '-', may be user name in future releasest date of the requestr status line (e.g. ``GET / HTTP/1.1``)s statusb response length or '-'f referera user agentT request time in secondsD request time in microsecondsL request time in decimal secondsp process ID"""accesslog = appRootPath + "/logs/gunicorn_access.log" #访问日志文件errorlog = appRootPath + "/logs/gunicorn_error.log" #错误日志文件 |

然后正常运行方法是：
指定配置文件
1 | supervisord -c conf/supervisor/supervisord_local.conf |
即可运行，之后即可去管理：
