While I use the connect statement, it shows the following error
The controller is not available at localhost:9999: java.net.ConnectException: JBAS012174:
Could not connect to remote://localhost:9999. The connection failed: JBAS012174: Could not
connect to remote://localhost:9999. The connection failed: Connection refused
[disconnected /]
I had the problem with connecting to the native management interface on port 9999 and all I ended up needing to do was enable the interface by adding the following to the standalone.XML file:
<management-interfaces>
<native-interface security-realm="ManagementRealm">
<socket-binding native="management-native"/>
</native-interface>
:
<management-interfaces>
The actual native management binding (HOST:PORT) is defined in JBoss configuration file as interface name="management" and socket-binding name="management-native". By default they use localhost and 9999.
When install system service, it is necessary to specify the correct /controller host:port values if management binding has been updated.
The error below in the log indicates the CLI command line cannot connect to the management interface when shutting down:
Could not connect to remote://localhost:9999. The connection failed
Confirm the /controller parameter used when configuring system service matches the management interface and socket binding definition in JBoss configuration file (standalone.xml / domain.xml and host.xml).
When configuring system service, if not specified, the default configuration for controller is :
/controller HOST:PORT The host and port of the management interface. If omitted, the default is localhost:9999.
Change this parameter to match the management interface and socket binding settings in the JBoss configuration file:
<interfaces>
<interface name="management">
<inet-address value="192.168.0.1"/>
</interface>
......
</interfaces>
<socket-binding-group name="standard-sockets" default-interface="public" port-offset="${jboss.socket.binding.port-offset:0}">
<socket-binding name="management-native" interface="management" port="${jboss.management.native.port:9999}"/>
With such configuration above you need to specify /controller as below to install the system service
service.bat install /startup /controller=192.168.0.1:9999 /config standalone-customized-1.xml
If jboss.socket.binding.port-offset is set, confirm actual port number (after offset) is passed in /controller parameter. For example, if jboss.socket.binding.port-offset is set as 300 in standalon.xml, you need to use 10299 (default 9999 + 300) as PORT number to install system service:
service.bat install /startup /controller=192.168.0.1:10299 /config standalone-customized-2.xml

I'm trying to deploy a Spring Boot Rest Api (Gradle) to an Azure app service. There is an executable jar in the /home/site/wwwroot folder and a startup command (java -jar /home/site/wwwroot/app.jar). When I execute this script, the spring api starts but throws the following error: "The Tomcat connector configured to listen on port 80 failed to start. The port may already be in use or the connector may be misconfigured."
I can't run the app on another port because the Azure App Service only allows inbound HTTP traffic on port 80 and 443 for SSL. I tried killing the process that is running on port 80 but that kills my ssh terminal.
Is there a solution to 'clear' the proces running on port 80 and actually run my Spring application on it?
"The Tomcat connector configured to listen on port 80 failed to start.The port may already be in use or the connector may be misconfigured."
The error is because another process is running on the same port. To solve this, you have two options.
Try to run the application on a port other than 8080.
Identify and stop the process running on that specific port.
Check this post on how to change the default tomcat port number.
See: how the spring boot configuration works.
Check this blog and SO thread might be helpful. Tomcat Server Error - Port 8080 already in use
I have a Java application that uses Wildfly 16, on dedicated Linux server, running WHM CentOS 6.10. The application works on the IP Adresss port 8080.
The Apache 2.4 is installed and running. I was told Apache uses port 80 which the domain name resides on. I can see from the domain URL the boilerplate index.html page which is under public_html but do not the WildFly index page.
The IP address port 8080 does show the WildFly index page. Which needs to be shown using the domain name.
I tried the following:
./bin/standalone.sh -Djboss.http.port=80
ERROR [org.jboss.msc.service.fail] (MSC service thread 1-5) MSC000001: Failed to start service org.wildfly.undertow.listener.default: org.jboss.msc.service.StartException in service org.wildfly.undertow.listener.default: Address already in use /127.0.0.1:80
Within the standalone.xml I changed the following:
<socket-binding name="http" port="80"/>
Unfortunately I do not know a way to post all of the error but I am able to submit the following:
ERROR [org.jboss.as.controller.management-operation] - failure description: "WFLYCTL0080: Failed services" => "org.wildfly.undertow.listener.default"

Tried again in standalone.xml by changing the following:
<socket-binding name="http" port="${jboss.http.port:80}"/>
ERROR [org.jboss.as.controller.management-operation] WFLYCTL0013: Operation ("add") failed -address:

WFLYCTL0448: 2 additional services are down due to their dependencies being missing or failed
Lastly, in case this help, this standalone.xml also includes the following:
<interfaces>
<interface name="management">
<inet-address value="${jboss.bind.address.management:127.0.0.1}"/>
</interface>
<interface name="public">
<inet-address value="${jboss.bind.address:127.0.0.1}"/>
</interface>
</interfaces>
Please help to switch the application from IP Address, port 8080 to show in the domain URL. Perhaps I need to forward or point domain to the JBOSS home directory. Not sure or how. Any help would be greatly appreciated.
You're getting an "Address already in use error" because Apache httpd is already bound to port 80. Therefore, you can't bind your WildFly Java app to port 80 and your Java app will not start because of this. You'll need to configure/integrate your Apache Web Server with WildFly. Something like Apache serves static content while WildFly is its application server. You'll have something like this in your httpd.conf:
JkWorkersFile conf/workers.properties
JkLogFile logs/mod_jk.log
JkLogLevel info
JkLogStampFormat "[%a %b %d %H:%M:%S %Y]"
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
JkRequestLogFormat "%w %V %T"
LoadModule jk_module modules/mod_jk.so
then you'll have something like this in your vhosts.conf:
<VirtualHost *:80>
ServerName example.com
DocumentRoot "/dir/dir"
... snipped ...
JkMount /* jboss
</VirtualHost>
then something like this in workers.properties:
worker.list = jboss
worker.jboss.type=ajp13
worker.jboss.host=localhost
worker.jboss.port=8009
then in standalone.xml:
<socket-binding-group ... snipped ... >
<socket-binding name="ajp" port="${jboss.ajp.port:8009}" />
... snipped ...
</socket-binding-group>
Using Apache as a Reverse Proxy to Wildfly through mod_proxy with CentOS.
Verify the config file (httpd.conf) Apache uses
httpd - V | grep SERVER_CONFIG_FILE
Verify the modules are enabled, either in httpd.conf or in modules includes files
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so
Since the httpd.conf file warned against updates in file due to new Apache upgrades or regeneration of config file, to instead use the config include files. In this case the includes/post_virtualhost_global.conf (not pre_virtualhost_global.conf).
Add the following to includes/post_virtualhost_global.conf
ProxyPreserveHost On
Proxypass / http://localhost:8080/
ProxypassReverse / http://localhost:8080/
Restart Apache service
service httpd stop
service httpd start
Whenever I try to run my spring boot application, my Linux machine returns me the following issue:

The Tomcat connector configured to listen on port 80 failed to start.
The port may already be in use or the connector may be misconfigured.
Hope someone can help me.
I'm guessing you're on Ubuntu. Ports under 1024 can only be opened by root so as a normal unprivileged user you can't run your app on port 80. Why not use another port using server.port property?
As clearly mentioned the port is already in use. Configure spring boot to use some other port.
As said in docs either set server.port as system property using command line option to jvm --server.port=8090 or add application.properties in /src/main/resources/ with
server.port = 8090
For random port use
server.port=0
Run it as root, if Ubuntu or Debian use Sudo your_command. Because ports under 1024 can be used just by root.
I'm using somata as my microservices platform for the web apps I'm building. I have successfully set up multiple clients on one machine with the somata registry running on the same machine. Now I want to have a client on one machine connect to a registry on another machine. How do I connect a client to a remote registry?
The simplest way is to use the environment variables SOMATA_REGISTRY_HOST (default "127.0.0.1") and SOMATA_REGISTRY_PORT (default 8420) when running your script:
SOMATA_REGISTRY_HOST=55.44.33.21 node test.js
The somata Client constructor also lets you connect to specific registries with the options registry_host and registry_port:
var client = new somata.Client({
registry_host: '55.44.33.21',
registry_port: 5858
})
Note: To allow connections from remote hosts, somata-registry will have to be run with its binding port as "0.0.0.0" instead of the default "127.0.0.1", which can be accomplished with the -h flag or SOMATA_REGISTRY_BIND_HOST environment variable when starting the registry. The -p flag and SOMATA_REGISTRY_BIND_PORT are also available for listening on a custom port.
somata-registry -h 0.0.0.0
or
SOMATA_REGISTRY_BIND_HOST=0.0.0.0 somata-registry
And of course you'll need access to the host and port from the remote machine.
i setup a jboss7 server including the standalon.xml for remote access on a debian machine.
But I cant get external remote access.
This is my interface part of the standalone.xml:
<interfaces>
<interface name="management">
<inet-address value="192.168.3.182"/>
</interface>
<interface name="public">
<inet-address value="192.168.3.182"/>
</interface>
</interfaces>
I also tried:
<interfaces>
<interface name="management">
<inet-address value="127.0.0.1"/>
</interface>
<interface name="public">
<any-ipv4-address/>
</interface>
</interfaces>
I tried a lot of possibilities to setting up the standalone.xml but I must forgot something.
I see the jboss7 homepage when I type the ip address in my browser but Im note able to connect with my java test client on the remote port(4447).
The test client works if the client runs local on the machine.
Do you have an idea?
Edit: telnet 192.168.3.182 4447 gives me the ip back with a blink cursor, so i guess waiting for response additional i see a log entry in my jboss server log -> ) JBREM000200: Remote connection failed: java.io.IOException: Received an invalid message length of 1728579688
I would check if the port is listening with the following command under linux "netstat -tulpn | grep -i 4447"
Good luck,
that "Received an invalid message length of 1728579688" error indicates that jboss is listening on the port but that the connector is not using the right kind of protocol.
of course, if you are connecting with telnet then you would expect to see that error since telnet is not a JMX client.
JBoss uses JBoss Remoting for JMX connections. So if you are using an external client, you need to make sure the JBoss Remoting libraries are available to your client.
This is a good description of the issue using VisualVM as the client:
