Question

flask+nginx+gunicorn+supervisor用docker方式部署，用supervisor启动后，访问http://127.0.0.1 只能看到nginx的欢迎界面，无法看到flask的界面 相关代码如下： app.py from flask import Flask app = Flask(__name__) @app.route('/') def hello_world(): return 'Hello World!' if __name__ == '__main__': app.run(host='0.0.0.0', port=80) flask.conf server { listen 80; server_name 120.0.0.1; location / { proxy_pass http://127.0.0.1:8001; } } supervisor.conf [program:nginx-app] command = /usr/sbin/nginx -g "daemon off;" stdout_logfile = /var/log/supervisor/nginx_stdout.log stdout_logfile_maxbytes = 10MB stderr_logfile = /var/log/supervisor/nginx_error.log stderr_logfile_maxbytes = 10MB [program:app-gunicorn] command = /usr/local/bin/gunicorn -w 4 -b 127.0.0.1:8001 app:app directory = /app stdout_logfile = /var/log/supervisor/gunicorn_out.log stdout_logfile_maxbytes = 10MB stderr_logfile = /var/log/supervisor/gunicorn_error.log stderr_logfile_maxbytes = 10MB gunicorn日志： [2018-12-12 03:29:48 +0000] [8824] [INFO] Starting gunicorn 19.9.0 [2018-12-12 03:29:48 +0000] [8824] [INFO] Listening at: http://127.0.0.1:8001 (8824) [2018-12-12 03:29:48 +0000] [8824] [INFO] Using worker: sync [2018-12-12 03:29:48 +0000] [8829] [INFO] Booting worker with pid: 8829 [2018-12-12 03:29:49 +0000] [8830] [INFO] Booting worker with pid: 8830 [2018-12-12 03:29:49 +0000] [8831] [INFO] Booting worker with pid: 8831 [2018-12-12 03:29:49 +0000] [8834] [INFO] Booting worker with pid: 8834 启动supervisor后，只能看到nginx欢迎界面，求解~

Answer 1

nginx 配置中 server block 里配的不对；这样写 server_name _; 或者 listen 80 default_server;
