我正在uWSGI中部署python flask应用程序。我遵循了本教程： https://www.digitalocean.com/community/tutorials/how-to-serve-flask-applications-with-uwsgi-and-nginx-on-ubuntu-14-04
我似乎无法在uwsgi上部署我的应用。
当我手动执行ff命令时：
exec /app/myapp_be/myapp_be_env/bin/uwsgi --ini /app/myapp_be/myapp.ini
它确实有效！但是，如果我尝试通过“ service uwsgi start”启动uwsgi.service（包含在/ etc / systemd / system /中），它将返回ff：
“正在启动应用服务器：uwsgi->！失败！”
我尝试检查/var/log/uwsgi/app/myapp.log中的日志。这是我看到的：

这是我的myapp.ini：
[uwsgi]
binary-path = /app/myapp_be/myapp_be_env
virtualenv = /app/myapp_be/myapp_be_env
chdir = /app/myapp_be
module = main_backend_app
python-path = /app/myapp_be
workers = 4
callable = app
master = true
processes = 5
plugin = python27
http = 0.0.0.0:5000
chown-socket = www-data
chmod-socket = 777
vacuum = true
emperor = true
enable-threads = true
home = /app/myapp_be/myapp_be_env
die-on-term = true
这是uwsgi.service：
