Question

我正在尝试遵循以下指导来部署Flask服务器：https://medium.com/ymedialabs-innovation/deploy-flask-app-with-nginx-using-gunicorn-and-supervisor-d7a93aa07c18

我按照所有步骤进行了操作，除了主管部分，我完全跳过了该部分，因为该命令不起作用，但是让事情起作用并不重要。

当我跑步时：sudo nginx -t

我得到：nginx: [emerg] socket() [::]:80 failed (97: Address family not supported by protocol)

什么是问题？我看到其他人遇到此错误，但是解决方案似乎对我不起作用？

这是我的nginx conf文件：

server {
    listen   80;
    server_name  <name>;

    location / {
        proxy_pass http://127.0.0.1:8000;
    }
}

#
# A virtual host using mix of IP-, name-, and port-based configuration
#

#server {
#    listen   8000;
#    listen   somename:8080;
#    server_name  somename  alias  another.alias;

#    location / {
#        root   html;
#        index  index.html index.htm;
#    }
#}

还有python flask服务器：

from flask import Flask
from flask import render_template
from flask import send_file

app = Flask(__name__, static_url_path="/static", static_folder="/static")
app.static_folder = 'static'

@app.route("/")
def index():
    return render_template("index.html")

@app.route("/uploads/resume")
def download_resume():
    return send_file("static/documents/resume.pdf")

if __name__ == '__main__':
    app.run(port=5010, debug=False, host='0.0.0.0')

Answer 1

转到/ etc / nginx / sites-available / default
禁用IPV6

我刚刚注释了以下一行

listen [::]:80 default_server ipv6only=on;
