Deploying applications to WildFly Server - The Hard Way

Download a copy of WildFly, and extract files into your local system.

Start and Stop WildFly Server

In the <WildFly dir>/bin folder, there are a few command tools used to manage WildFly server.

Open your terminal, enter <WildFly dir>/bin.

Execute the following command to start WildFly Servers in standalone mode.

# Linux
./standalone.sh
# windows
standalone

Execute the following command to start WildFly Servers in domain mode.

# Linux
./domain.sh
# windows
domain

To stop a running WildFly Server, jus terminate the process by Ctrl+C.

Deploy applications

Firstly package the application into a war package.

# mvn clean package
...

After it done there is a jakartaee8-starter.war is located in the target folder.

Copy this file to <WildFly dir>/standalone/deployments.

In the WildFly console, you will see the following deployment info.

To undeploy an applicaiton, just delete jakartaee8-starter.war.deployed in the <WildFly dir>/standalone/deployments.

In the WildFly console, there is undeployment info displayed.

17:57:41,787 INFO  [org.jboss.as.server] (DeploymentScanner-threads - 1) WFLYSRV0009: Undeployed "jakartaee8-starter.war" (runtime-name: "jakartaee8-starter.war")

Add an administration user

Admin user is required to access management console or remote deployment from Maven plugin, etc.

Enter <WildFly dir>/bin , execute add-user to add a user.

# add-user

 b) Application User (application-users.properties)

 a) Update the existing user password and roles
 b) Enable the existing user
 c) Type a new username
(a): b
Updated user 'admin' to file 'D:\appsvr\wildfly\standalone\configuration\mgmt-users.properties'
Updated user 'admin' to file 'D:\appsvr\wildfly\domain\configuration\mgmt-users.properties'
Updated user 'admin' with groups null to file 'D:\appsvr\wildfly\standalone\configuration\mgmt-groups.properties'
Updated user 'admin' with groups null to file 'D:\appsvr\wildfly\domain\configuration\mgmt-groups.properties'
Press any key to continue . . .

There is an existing admin user , just enable it. If you want to update the password and roles, run add-user again, the select a) Update the existing user password and roles in the second step, input your new password, add it to the required groups. There are seven groups available in WildFly.
