之前折腾了很长时间：
都无法正常实现：
将Nginx的请求，转到Flask。
所以放弃了uWSGI。
之前已经通过
在虚拟环境中，用
pip install gunicorn
了：
(SIPEvents) SIPEvents pip install gunicorn Collecting gunicorn Downloading gunicorn-19.6.0-py2.py3-none-any.whl (114kB) 100% || 122kB 89kB/s Installing collected packages: gunicorn Successfully installed gunicorn-19.6.0 (SIPEvents) SIPEvents |
现在接着继续。

［已解决］Flask中用gunicorn和Nginx出错：502 Bad Gateway
后来再去把IP地址，换成域名：
(SIPEvents) ➜ SIPEvents cat /etc/nginx/conf.d/default.conf server { listen 80; #server_name 115.29.173.126; server_name hd.webonn.com; access_log /var/log/nginx/access.log; error_log /var/log/nginx/error.log; location / { proxy_pass http://127.0.0.1:8080/; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; } } |
重启nginx：
(SIPEvents) ➜ SIPEvents service nginx restart Stopping nginx: [ OK ] Starting nginx: [ OK ] |
用gunicorn启动Flask：
(SIPEvents) ➜ SIPEvents gunicorn -w 4 -b 127.0.0.1:8080 app:app [2016-08-18 18:00:29 +0000] [20930] [INFO] Starting gunicorn 19.6.0 [2016-08-18 18:00:29 +0000] [20930] [INFO] Listening at: http://127.0.0.1:8080 (20930) [2016-08-18 18:00:29 +0000] [20930] [INFO] Using worker: sync [2016-08-18 18:00:29 +0000] [20935] [INFO] Booting worker with pid: 20935 [2016-08-18 18:00:29 +0000] [20938] [INFO] Booting worker with pid: 20938 [2016-08-18 18:00:29 +0000] [20939] [INFO] Booting worker with pid: 20939 [2016-08-18 18:00:29 +0000] [20944] [INFO] Booting worker with pid: 20944 |
然后再去浏览器中访问：
即可正常显示：
中断运行：
