reverse-proxy

问题 I've a situation where two webservers are setup with nginx as loadbalancer and are backends themselves. Distribution is Debian Wheezy. Config is the same on both servers (Quad-Core with 32GB RAM) TCP #/etc/sysctl.conf vm.swappiness=0 net.ipv4.tcp_window_scaling=1 net.ipv4.tcp_timestamps=1 net.ipv4.tcp_sack=1 net.ipv4.ip_local_port_range=2000 65535 net.ipv4.tcp_max_syn_backlog=65535 net.core.somaxconn=65535 net.ipv4.tcp_max_tw_buckets=2000000 net.core.netdev_max_backlog=65535 net.ipv4.tcp

问题 I want to pass all Python's traffics through a http proxy server, I checked urlib2 and requests packages for instance, they can be configured to use proxies but how could I use something like a system-wide proxy for Python to proxy all the data out? 回答1: Linux system first export the environment variables like this $ export http_proxy="http://<user>:<pass>@<proxy>:<port>" $ export HTTP_PROXY="http://<user>:<pass>@<proxy>:<port>" $ export https_proxy="http://<user>:<pass>@<proxy>:<port>" $

问题 I use reverse proxy with Nginx and I want to force the request into HTTPS, so if a user wants to access the url with http, he will be automatically redirected to HTTPS. I'm also using a non-standard port. Here is my nginx reverse proxy config: server { listen 8001 ssl; ssl_certificate /home/xxx/server.crt; ssl_certificate_key /home/xxx/server.key; location / { proxy_pass https://localhost:8000; proxy_redirect off; proxy_set_header Host $host:$server_port; proxy_set_header X-Forwarded-For

问题 I am running my app on Google App engine and I have linked my domain which I bought from GoDaddy to the app engine along with the SSL which I have also bought from GoDaddy. I read it on many sites that running server on port 80 without Reverse Proxy can cause you major security issues. But I can't see which of these issues are they talking about. Also as I am running my app on port 5555 I even tried to ping my domain and the IP was 216.239.XX.21 where X possible values can be (32, 34, 36 and

问题 I'm having this problem with GWT when it's behind a reverse proxy. The backend app is deployed within a context - let's call it /context. The GWT app works fine when I hit it directly: http://host:8080/context/ I can configure a reverse proxy in front it it. Here's my nginx example: upstream backend { server 127.0.0.1:8080; } ... location / { proxy_pass http://backend/context/; } But, when I run through the reverse proxy, GWT gets confused, saying: 2009-10-04 14:05:41.140:/:WARN: Login: ERROR

问题 What are the advantages of having nginx or another web-server running as a reverse-proxy in front of the Node.JS? What does it provide? (This question is intended for matters concerning web-apps, not web-pages). Thank you. 回答1: I think the greatest benefit is that you're then able to use the same port (80) for multiple applications. Otherwise, you'd need a new IP address for each nodejs application you have. Depending on how you set things up, you can also configure different folders and

问题 Basically my scenario is that I have an internal website that requires a SINGLE hard-coded username and password to access (and this can't be turned off, only changed). I am exposing this website through a reverse proxy for various reasons (hiding the port, simplifying url, simplifying NAT, etc). However, what I would like to do is be able to use Apache to handle the authentication so that: I don't have to give out single password to everyone I can have multiple usernames and passwords using

问题 Ok, so for development purposes, we have a dedicated web server. It's not currently connected directly to the internet, so I've setup an apache reverse proxy on another server, which forwards to the development server. This way, I can get web access to the server. The problem is, the routes in Laravel are now being prefixed with the internal server IP address, or the servers computer name. For example, I go to http://subdomain.test.com but all the routes, generated using the route() helper,

问题 I have a reverse proxy that does HTTPS on the outside, but HTTP on the inside. This means that by default in-app URLs will have HTTP as the scheme, as this is the way it's being contacted. How can the proxy tell the backend that HTTPS should be used? 回答1: The proxy can add extra (or overwrite) headers to requests it receives and passes through to the back-end. These can be used to communicate information to the back-end. So far I've seen a couple used for forcing the use of https in URL

问题 my nginx server is actually proxying my node backend (which listens on port 3000) with a simple: location /api/ { proxy_pass http://upstream_1; } Where upstream_1 is my node cluster defined in nginx.conf (on port 3000). I'm gonna have to add SSL over http connections, so I have the following question: do I only need to configure nginx to enable ssl? And it will automatically "uncrypt" the request and pass it uncrypted to Node which will be able to handle it normally? Or do I need to configure
