Description:
The Tomcat connector configured to listen on port 8080 failed to start. The port may already be in use or the connector may be misconfigured.
Action:
Verify the connector's configuration, identify and stop any process that's listening on port 8080, or configure this application to listen on another port.
Seems like 8080 port is already used by some other process.
Change the port of spring-boot tomcat port by adding the server.port=8090 in application.properties.
Change 8090 to any port you want to use.
Your 8080 port is already used by some other process.
Change the port of spring-boot server.port=8090 in application.properties.
You can change your application run server port any port number to if that port number would not belong to any other process on your computer.
and another thing if you use IntelliJ idea to develop, accidentally close your IDE without proper way this error may have occurred {personal experience}.
It is not necessarily required to change the port, you can just end the process of it to release it in your spring application
Open cmd as administrator and enter the following commands:
netstat -year | findstr 9330
Once you find the process number, type it in the highlight of the following command:
taskkill /F /PID <Process ID>
The result should appear as follows:
SUCCESS: The process with PID < Process Id > has ended.

Web server failed to start. Port 8080 was already in use.

I can set port in every console application but I need to run at least 10 console application at the same time.
Do I have any config or solution for application auto-change port?
You can auto generate port number to get rid from Port was already in use. just put server.port= 0 in properties or yml. It is auto generate server port in console.
application.properties
server.port= 0
application.yml
server:
port : 0
console

2019-12-28 09:49:48.561 ERROR 482 --- [ main] o.s.boot.SpringApplication : Application run failed
when I try to start server with command:
java -jar jin-alpha-1.0.jar
under AWS Ubuntu linux server.
In case of trying to local start server was success.
The Changed port is suspicious the reason why before changed It work.
I changed Server port from 8080 to 80.(The reason why AWS http allowed only 80 port)
Local Case : The port of Tomcat server ==> 8080 and 80, Both of them are work. and Stared
AWS Ubuntu : Start with 8080 is work but 80 is not work and Error displayed Above.
I got solution.
I Changed Tomcat port from 80 to 8080. so Server started under Aws ubuntu.
(I don't still know why 80 port is not work under Aws Ubutu)
and Add "Custom TCP Rule" with 8080 port Range.
These are called Priviliged ports on *nix systems. The TCP/IP port numbers below 1024 are special in that normal users are not allowed to run servers on them. This is a security feaure, in that if you connect to a service on one of these ports you can be fairly sure that you have the real thing, and not a fake which some hacker has put up for you.
The normal port number for W3 servers is port 80. This number has been assigned to WWW by the Internet Assigned Numbers Authority, IANA.
When you run a server as a test from a non-priviliged account, you will normally test it on other ports, such as 2784, 5000, 8001 or 8080.
Hope this explains why you cannot run on 80. There are workarounds like running as root. Which I dont recommend as if some hacker gets access to the service then they get root privileges on the box. You need to be careful not running services on such ports.
Unable to run my project
I am just learning Springboot, following instruction from internet I set up a new project, I use Eclipse Oxygen + Maven (with Embedded Tomcat) + Springboot , I followed the instruction to run the project, but got following error message. I changed the port many times by revising "application.properties" file, but it didn't work. I checked all the ports, their states are "listening".

confirm To you can not use Same Port "8080" More Then One Application And also confirm to another application is not using same port
(Example:- you are going to run your application on Spring with Port 8080 and in Background Another application already was allocated port like XAMPP OR WAPP)
Check Listening Port
Make sure that new port you are going to set is not being used by
other processes. You can check the listening port as below
After Changing the port, Close and Reopen the Project and do Clean, Rebuild your
Project.
PowerShell
Get-Process -Id (Get-NetTCPConnection -LocalPort portNumber).OwningProcess
cmd
C:\> netstat -a -b
Solution
Kill Process on Port 8080 from cmd
netstat -ano | findstr :<yourPortNumber>
taskkill /PID <typeyourPIDhere> /F
OR Change the Port
Update via a properties file.
server.port=8888 # Server HTTP port.
Update via a yaml file.
server:
port: 8888
Actually, it is not a problem, but a strange thing I would like to understand. I use SpringBoot2 with embedded Tomcat. And I've added self-signed SSL certificate. This is pretty usual config:
server.ssl.key-store-type=PKCS12
server.ssl.key-store=classpath:keystore.p12
server.ssl.key-store-password=123456
server.ssl.key-alias=tomcat
server.port=8443
And I made a connector, to force http -> https redirect, like in many examples:
private Connector getHttpConnector() {
Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
connector.setScheme("http");
connector.setPort(8080);
connector.setSecure(false);
connector.setRedirectPort(8443);
return connector;
}
If I would not specify server.port property in my config, I will see the following error:
Description:
The Tomcat connector configured to listen on port 8080 failed to
start. The port may already be in use or the connector may be
misconfigured.
Action:
Verify the connector's configuration, identify and stop any process
that's listening on port 8080, or configure this application to listen
on another port.
But if I will, I will see following:
o.s.b.w.embedded.tomcat.TomcatWebServer : Tomcat started on port(s):
8443 (https) 8080 (http) with context path ''
Why server.port starts to point at https port??? Even sources of springframework.boot.autoconfigure.web.ServerProperties says that it is
/**
* Server HTTP port.
*/
Is it ok, or I've got something strange in my server? Or this is how Conectors works? :) Thank you
By default, the embedded server start on port 8080 if you don't give any value for server.port in the properties file
And you are also specifying connectors port as 8080 (connector.setPort(8080);)
Hence you are getting port conflicts.
Spring Boot app is configured (default) to run Tomcat on port 8080. This application gets deployed on AWS via BoxFuse tool and exposed at port 8080 (as expected/configured).
I have tried setting server port to 80 in boot application properties but it causes permission denied issue and the solution seems to be modifying iptables or reverse proxy. ipTables modification is not possible due to boxFuse image/env not being editable.
Question: Is there a way in BoxFuse to setup the spring boot application on port 80 without actually setting up another instance for reverse proxy? It is an overhead to setup an instance just for port correction since can't change the iptables.
Also, Is it possible that this application is run with root privileges on the AWS instance so that I do not need to modify iptables or set up reverse proxy?
There is a -ports.Name option available when deploying the application with BoxFuse.
Docs: https://cloudcaptain.sh/docs/gradle/run
Example:
boxfuse -ports.http=80 -env=test run myapprepo/myapp:0.1
Verified on local dev environment. For Mac, it should be run as a privileged command via sudo
sudo boxfuse -ports.http=80 run myapprepo/myapp:0.1
To add, works for 443 too.
