我一直在努力使用uWSGI将烧瓶应用程序部署到我的服务器 皇帝模式整天都不知道为什么它不起作用。我在这里阅读了所有其他的uWSGI Emperor模式问题。问#uwsgi＆amp;没有回复的邮件列表。
我的设置是nginx（1.4.6-1ubuntu3.2），uWSGI == 2.0.10通过pip安装 进入virtualenv，Flask == 0.10.1和Python 3.4.0。监督是 负责启动皇帝进程。
当我手动绑定到TCP端口时，烧瓶应用程序本身正常工作，当我手动运行uwsgi时：
uwsgi -s /tmp/oauthsvc.sock -w wsgi --stats /tmp/oauthsvc-stats.sock
我注意到即使我认为我配置了附庸使用 unix socket，它在启动时报告它正在监听http://127.0.0.1:5000/
我用strace验证了nginx正在打开套接字和权限 该套接字是777：
srwxrwxrwx 1 oauthsvc oauthsvc 0 Jun 3 18:34 /tmp/oauthsvc.sock
srwxrwxrwx 1 oauthsvc oauthsvc 0 Jun 3 18:08 /tmp/oauthsvc-stats.sock
但这种联系最终只是超时。
我的配置＆amp;一些日志输出如下。
nginx配置非常简单：
server {
listen 80;
server_name default;
location = /robots.txt { access_log off; log_not_found off; }
location = /favicon.ico { access_log off; log_not_found off; }
location / {
include uwsgi_params;
uwsgi_pass unix:/tmp/oauthsvc.sock;
}
}
supervisor使用以下命令启动emporer进程：
[program:oauthsvc-emperor]
command=/services/oauthsvc/services/oauthsvc/bin/uwsgi --emperor /services/oauthsvc/etc/uwsgi/vassals --die-on-term --uid 1005 --gid 1005 --logto /services/oauthsvc/var/log/uwsgi/emperor.log
user=oauthsvc
autostart=true
autorestart=true
redirect_stderr=true
vassal的ini文件如下：
[uwsgi]
# do not turn on master mode when spawned by emperor
# http://stackoverflow.com/questions/15055002/uwsgi-master-with-emperor-spawns-two-emperors
#master = true
protocol = uwsgi
socket = /tmp/oauthsvc.sock
stats = /tmp/oauthsvc-stats.sock
daemonize = /services/oauthsvc/var/log/uwsgi/oauthsvc.log
chdir = /services/oauthsvc/services/oauthsvc/oauthsvc-server
wsgi-file = wsgi.py
callable = app
chmod-socket = 777
uid = 1005
gid = 1005
virtualenv = /services/oauthsvc/services/oauthsvc
# PYTHONHOME
home = /services/oauthsvc/services/oauthsvc
#env =
processes = 4
vacuum = true
# If you start uWSGI without threads, the Python GIL will not be enabled, so
# threads generated by your application will never run unless you include:
enable-threads = true
harakiri = 30
最后，wsgi.py：
#!/usr/bin/env python3
from oauthsvc.flask.server import parse_args, configured_app
args = parse_args()
app = configured_app(args.config, debug=args.debug)
app.run()
