Nginx proxy_read_timeout max value

There comes a time when you really need to increase the amount of time it takes before your server stops a particular PHP process from continuing. Under normal conditions you want to keep these values low so your connections are as efficient as possible.

These limits are also in place to prevent poorly written scripts from monopolizing too many resources on your server. Starting with Apache, you first have to determine which PHP handler you are working with. If this value is not present, then PHP should default to 60 seconds. When you set this higher, it allows all scripts to run as long as the value in seconds you place here. If you can not set additional limits in your application itself — this should be the only place you need to make changes to PHP.

Finding the path is not always as easy as you would think. Some servers wind up a bit messy and multiple php. To find yours in the fastest way possible open up an SSH prompt and type the following:. This command outputs out of the PHP configuration values and information much like the phpinfo ; command would produce.

It is found that a request has been processed in the background for 1 minute. The result is that the status code of the request is gateway time out.

Understand all the timeout related configurations of nginx, as follows:. If other requests are received from the client, the server will take advantage of the unclosed connection without establishing another connection. If there is no new request, the TCP connection will be closed. If the probe packet does not return, the TCP connection is closed. The above is the whole content of this article, I hope to help you in your study, and I hope you can support developeppaer more.

Parameter value can contain variables 1. The special value off 1. The transparent parameter 1. In order for this parameter to work, it is usually necessary to run nginx worker processes with the superuser privileges. On Linux it is not required 1. It is also necessary to configure kernel routing table to intercept network traffic from the proxied server.

Sets the size of the buffer used for reading the first part of the response received from the proxied server. This part usually contains a small response header. By default, the buffer size is equal to one memory page. This is either 4K or 8K, depending on a platform. It can be made smaller, however. If the whole response does not fit into memory, a part of it can be saved to a temporary file on the disk. When buffering is disabled, the response is passed to a client synchronously, immediately as it is received.

Sets the number and size of the buffers used for reading a response from the proxied server, for a single connection. When buffering of responses from the proxied server is enabled, limits the total size of buffers that can be busy sending a response to the client while the response is not yet fully read.

In the meantime, the rest of the buffers can be used for reading the response and, if needed, buffering part of the response to a temporary file. Defines a shared memory zone used for caching. The same zone can be used in several places.

The off parameter disables caching inherited from the previous configuration level. Allows starting a background subrequest to update an expired cache item, while a stale cached response is returned to the client.

Note that it is necessary to allow the usage of a stale cached response when it is being updated. Defines conditions under which the response will not be taken from a cache.

If the last request passed to the proxied server for populating a new cache element has not completed for the specified timeone more request may be passed to the proxied server. When the time expires, the request will be passed to the proxied server, however, the response will not be cached.

Sets an offset in bytes for byte-range requests. If the range is beyond the offset, the range request will be passed to the proxied server and the response will not be cached. If the client request method is listed in this directive then the response will be cached.

Sets the path and other parameters of a cache. Cache data are stored in files. The file name in a cache is a result of applying the MD5 function to the cache key. The levels parameter defines hierarchy levels of a cache: from 1 to 3, each level accepts values 1 or 2.

For example, in the following configuration. A cached response is first written to a temporary file, and then the file is renamed. Starting from version 0. However, be aware that in this case a file is copied across two file systems instead of the cheap renaming operation. It is thus recommended that for any given location both cache and a directory holding temporary files are put on the same file system.

If the value is set to offtemporary files will be put directly in the cache directory. One megabyte zone can store about 8 thousand keys.Join Stack Overflow to learn, share knowledge, and build your career.

I'm using java-websocket for my websocket needs, inside a wowza application, and using nginx for ssl, proxying the requests to java. The problem is that the connection seems to be cut after exactly 1 hour, server-side. The client-side doesn't even know that it was disconnected for quite some time.

I don't want to just adjust the timeout on nginx, I want to understand why the connection is being terminated, as the socket is functioning as usual until it isn't. The timeout could be coming from the client, nginx, or the back-end.

nginx proxy_read_timeout max value

When you say that it is being cut "server side" I take that to mean that you have demonstrated that it is not the client. Your nginx configuration looks like it shouldn't timeout for 1 dayso that leaves only the back-end. My first suggestion is that you try connecting directly to the back-end and confirm that the problem still occurs taking nginx out of the picture for troubleshooting purposes.

Note that you can do this with command line utilities like curlif using a browser is not practical. Here is an example test command:. In my working case, running the above example stayed open indefinitely I stopped with Ctrl-C manually since neither curl nor my server was implementing a timeout. However, when I changed this to go through nginx as a proxy with default timeout of 1 minute as shown below I saw a response from nginx after almost exactly 1 minute.

Besides, although that might keep the inner connection open I don't think it is able to keep the end-to-end stream intact.

Finally, there's a note in the WebSocket proxying doc that hints at a good solution:. Alternatively, the proxied server can be configured to periodically send WebSocket ping frames to reset the timeout and check if the connection is still alive.

Most likely it's because your configuration for the websocket proxy needs tweaking a little, but since you asked:. There are some challenges that a reverse proxy server faces in supporting WebSocket. Within your location directive which handles your websocket proxying you need to include the headers, this is the example Nginx give:. For NGINX to send the Upgrade request from the client to the backend server, the Upgrade and Connection headers must be set explicitly, as in this example.

I'd also recommend you have a look at the Nginx Nchan module which adds websocket functionality directly into Nginx.Server Fault is a question and answer site for system and network administrators.
