How to modify the maximum number of Tomcat connections, in view of this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

First, open the home page of tomcat's official website: http://tomcat.apache.org/

Then, we click the corresponding version of Tomcat under "Documentation" in the left navigation bar to go to the home page of the tomcat document.

Then, find the Configuration under Reference in the left navigation bar and click in

Finally, find the HTTP/1.1 in Connectors in the left navigation bar.

Http://tomcat.apache.org/

Http://tomcat.apache.org/tomcat-8.5-doc/index.html

Http://tomcat.apache.org/tomcat-8.5-doc/config/http.html

This sentence has been introduced very clearly:

If more simultaneous requests are received than can be handled by the currently available request processing threads, additional threads will be created up to the configured maximum (the value of the maxThreads attribute). If still more simultaneous requests are received, they are stacked up inside the server socket created by the Connector, up to the configured maximum (the value of the acceptCount attribute).

So what we need to set are the values maxThreads and acceptCount:

Among them, maxThreads is introduced as follows:

The maximum number of request processing threads to be created by this Connector, which therefore determines the maximum number of simultaneous requests that can be handled. If not specified, this attribute is set to 200. If an executor is associated with this connector, this attribute is ignored as the connector will execute tasks using the executor rather than an internal thread pool.

The introduction of acceptCount is:

The maximum queue length for incoming connection requests when all possible request processing threads are in use. Any requests received when the queue is full will be refused. The default value is 100.

So the default values for both are 200 and 100, respectively. To adjust the default maximum number of connections for Tomcat, you can increase the values of these two properties and make acceptCount greater than or equal to maxThreads:

This is the answer to the question on how to modify the maximum number of connections in Tomcat. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel for more related knowledge.
