Python Bokeh服务器+；使用Nginx进行反向代理得到404

我正在尝试设置一个Bokeh服务器，并使用Nginx反向代理它

我的p-website.conf现在看起来像：

server {
listen   80;
server_name  website.com;
client_max_body_size 25M;
access_log  /var/www/logs/p-website.access.nginx.log;
error_log  /var/www/logs/p-website.error.nginx.log error;
root    /var/www/pydocs/website/production/src;

include global/restrictions.conf;


location /plot/ {
    proxy_pass http://website.com:5100;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_http_version 1.1;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $host:$server_port;
    proxy_buffering off;
}

location / {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

    # enable this if and only if you use HTTPS, this helps Rack
    # set the proper protocol for doing redirects:
    # proxy_set_header X-Forwarded-Proto https;

    proxy_set_header Host $http_host;
    proxy_redirect off;
    proxy_connect_timeout 10;
    proxy_read_timeout 60s;

    proxy_pass http://production_website_gunicorn;
}
}

server {
listen   80 default_server;
server_name  website.com;
client_max_body_size 25M;
access_log  /var/www/logs/p-website.access.nginx.log;
error_log  /var/www/logs/p-website.error.nginx.log error;
root    /var/www/pydocs/magnify/production/src;

include global/restrictions.conf;


location / {
    allow 127.0.0.1:5100
    proxy_pass http://127.0.0.1:5100;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_http_version 1.1;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $host:$server_port;
    proxy_buffering off;
}

}

在服务器上，我使用以下命令运行Bokeh服务器：

bokeh serve bokehserver.py --port 5100 --host website.com:80

bokeh serve bokehserver.py --port 5100 --host 127.0.0.1:80

但是当我访问website.com/plot/时，我从Bokeh得到了一个404，服务器终端给了我：WARNING:tornado.access:404 get/（“这里是ip地址”）3.04ms

我不明白为什么它总是给出404，或者与Nginx有关

谢谢

好吧，我想我又向前迈了一步，希望朝着好的方向前进。 我的p-website.conf现在看起来像：

server {
listen   80;
server_name  website.com;
client_max_body_size 25M;
access_log  /var/www/logs/p-website.access.nginx.log;
error_log  /var/www/logs/p-website.error.nginx.log error;
root    /var/www/pydocs/website/production/src;

include global/restrictions.conf;


location /plot/ {
    proxy_pass http://website.com:5100;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_http_version 1.1;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $host:$server_port;
    proxy_buffering off;
}

location / {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

    # enable this if and only if you use HTTPS, this helps Rack
    # set the proper protocol for doing redirects:
    # proxy_set_header X-Forwarded-Proto https;

    proxy_set_header Host $http_host;
    proxy_redirect off;
    proxy_connect_timeout 10;
    proxy_read_timeout 60s;

    proxy_pass http://production_website_gunicorn;
}
}

server {
listen   80 default_server;
server_name  website.com;
client_max_body_size 25M;
access_log  /var/www/logs/p-website.access.nginx.log;
error_log  /var/www/logs/p-website.error.nginx.log error;
root    /var/www/pydocs/magnify/production/src;

include global/restrictions.conf;


location / {
    allow 127.0.0.1:5100
    proxy_pass http://127.0.0.1:5100;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_http_version 1.1;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $host:$server_port;
    proxy_buffering off;
}

}

现在，我使用以下命令运行服务器：

bokeh serve bokehserver.py --port 5100 --host website.com:80

bokeh serve bokehserver.py --port 5100 --host 127.0.0.1:80

现在我再也没有404了，但是当我访问website.com:5100/bokehserver/时，我得到了一个“403:Forbidden”。在bokehserver终端上显示此消息：

INFO:bokeh.server.tornado:Rejected connection from host 'website.com:5100' because it is not in the --host whitelist
WARNING:tornado.access:403 GET /bokehserver/ (213.152.161.35) 0.78ms

我试图通过在p-website.conf中添加

allow 127.0.0.1:5100

来解决白名单问题，运气不好。

我解决了这个问题，显然您需要将--prefix=添加到Bokeh命令的相同位置：

bokeh serve bokehserver.py --port 5100 --prefix=/plot/ --host website.com:80

p-website.conf中的位置块如下所示：

location /plot/ {
    proxy_pass http://127.0.0.1:5100;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_http_version 1.1;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $host:$server_port;
    proxy_buffering off;
}

Bokeh服务器有一个默认（但可配置）URL前缀

“app”

。你能看到

website.com/plot/app/

上的页面吗？我在浏览器中看到了相同的404：“404:未找到”和终端中的相同消息：“警告：龙卷风。访问：404 get/plot/app/（“这里是ip地址”）0.58ms。nginx日志中有什么？nginx和bokeh服务器在不同的机器上吗？也许有什么东西阻塞了nginx和bokeh服务器之间的通信。是否可以在同一台计算机上使用

127.0.0.1

地址而不是

website.com

来尝试它们以获取数据点？error.nginx.log是空的，在access.nginx.log中只有404 get请求，而不是403（请参见上面的更新）：“get/bokehserver HTTP/1.1”404 1037“-”Mozilla/5.0（Macintosh；Intel Mac OS X 10.11；rv:47.0）Gecko/20100101 Firefox/47.0“它们运行在同一台机器上（Ubuntu 14.04 LTS）。您不应该导航到

website.com:5100/bokehserver

，它试图直接连接到Bokeh服务器，绕过您可能不想允许的nginx（在端口80上）（以及它拒绝您的原因）。您想点击nginx，所以您应该导航到

website.com/bokehserver

（或者更可能是：

website.com/app/bokehserver

，让nginx在内部转发连接。请注意，

--host

选项现在已被弃用，并将返回未知参数错误。
