折腾：
【已解决】Flask的gunicorn的启动任务管理supervisor
期间：
(SIPEvents) ➜ SIPEvents gunicorn app:hello [2016-08-18 16:58:05 +0000] [19941] [INFO] Starting gunicorn 19.6.0 [2016-08-18 16:58:05 +0000] [19941] [ERROR] Connection in use: (‘127.0.0.1’, 8000) [2016-08-18 16:58:05 +0000] [19941] [ERROR] Retrying in 1 second.

gunicorn -w 4 -b 127.0.0.1:8080 app:hello

此处的nginx的配置为：
(SIPEvents) ➜ SIPEvents cat /etc/nginx/conf.d/default.conf server { listen 80; #listen 80 default_server; server_name _; 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; } } |
(SIPEvents) ➜ SIPEvents service nginx restart Stopping nginx: [ OK ] Starting nginx: [ OK ] |
(SIPEvents) ➜ SIPEvents gunicorn -w 4 -b 127.0.0.1:8080 app:hello [2016-08-18 17:03:42 +0000] [20080] [INFO] Starting gunicorn 19.6.0 [2016-08-18 17:03:42 +0000] [20080] [INFO] Listening at: http://127.0.0.1:8080 (20080) [2016-08-18 17:03:42 +0000] [20080] [INFO] Using worker: sync [2016-08-18 17:03:42 +0000] [20085] [INFO] Booting worker with pid: 20085 [2016-08-18 17:03:42 +0000] [20086] [INFO] Booting worker with pid: 20086 [2016-08-18 17:03:42 +0000] [20091] [INFO] Booting worker with pid: 20091 [2016-08-18 17:03:42 +0000] [20092] [INFO] Booting worker with pid: 20092 |
去查看出错的log：
(SIPEvents) ➜ SIPEvents tail /var/log/nginx/error.log 。。。 2016/08/18 17:06:39 [crit] 20165#0: *1 connect() to unix:/tmp/uwsgi.sock failed (13: Permission denied) while connecting to upstream, client: 58.208.66.13, server: 127.0.0.1:8080, request: “GET / HTTP/1.1”, upstream: “uwsgi://unix:/tmp/uwsgi.sock:”, host: “115.29.173.126” |
看到有之前用到的：
/tmp/uwsgi.sock
所以去：
rm /tmp/uwsgi.sock
然后再去试试：
(SIPEvents) ➜ SIPEvents service nginx restart Stopping nginx: [ OK ] Starting nginx: [ OK ] |
502 Bad Gateway
搜：
flask gunicorn nginx 502 Bad Gateway
python – Nginx, Flask, Gunicorn 502 Error – Stack Overflow
Not Found The requested URL / was not found on this server. |
Flask install 502 Bad Gateway nginx | DigitalOcean
502 bad gateway: nginx & gunicorn – Server Fault
［总结］
此处，之所以出现：
502 Bad Gateway
的原因是：
nginx找不到服务器
解决办法是：
把nginx的配置中：
server_name _; |
改为：
server_name 115.29.173.126; |
就可以了。
之后又出现其它错误：
