How To Stop Wildfly Server In Windows

The WildFly CLI is a powerful assistants tool that exposes both an interactive console and scripting capabilities. The CLI tin exist used to query and configure all aspects of the WildFly application server, and in this post, I have a loftier level look at how to use the CLI.

Logging in

Download WildFly 11, excerpt it, and run bin/standalone.sh or bin\standalone.bat. This volition start WildFly with the default configuration, which is to bind the management interface to localhost on port 9990.

In another console run bin/jboss-cli.sh or bin\jboss-cli.bat with the --connect argument. Yous will be logged into the CLI:

          $ ./jboss-cli.sh --connect Alert: An illegal reflective access performance has occurred Warning: Illegal reflective admission by org.wildfly.security.manager.GetAccessibleDeclaredFieldAction (jar:file:/Users/matthewcasperson/Downloads/wildfly-11.0.0.Last/modules/arrangement/layers/base of operations/org/wildfly/security/elytron-private/main/wildfly-elytron-1.i.vi.Final.jar!/) to field coffee.security.AccessControlContext.context WARNING: Delight consider reporting this to the maintainers of org.wildfly.security.manager.GetAccessibleDeclaredFieldAction WARNING: Utilize --illegal-access=warn to enable warnings of farther illegal reflective admission operations Alert: All illegal access operations will be denied in a future release [standalone@localhost:9990 /]                  

From the example output above, we can come across three important things take happened.

First, Java 9 has reported some Illegal reflective access warnings. This sounds dire, but it's because of some intentional changes introduced with the Java 9 module system (known as Jigsaw). I wait that over time these warnings will be resolved, simply for now they can be ignored.

Second, nosotros accept connected to the default host (localhost) and port (9990) using the default protocol (remote+http). These could be specified manually with the --controller pick:

          ./jboss-cli.sh --connect --controller=remote+http://localhost:9990                  

The CLI accepts a number of dissimilar protocols. By default, remote+http or http-remoting can be used. If the direction interface is protected with SSL, so the protocols remote+https or https-remoting tin can exist used.

Older versions of WildFly exposed a native management port on 9999 by default, which required the protocol remoting. WildFly 11 does not expose the native direction port by default.

Third, we managed to log in without supplying any credentials. This is courtesy of a characteristic called silent authentication.

Silent authentication relies on admission to the standalone/tmp/auth or domain/tmp/auth directory. The idea is that if a user has access to this directory, they probably have access to create new users, and and so silent authentication gives y'all access.

If you deny write access to the auth directory, silent authentication will neglect, and you volition be prompted for credentials.

See Configuring Admin Users for details on creating an admin user that tin can be used to log into the CLI.

Looking around

The CLI is structured like a file organisation, and can exist navigated with the same commands you would utilize in a beat like Bash.

The ls command volition list the contents of the current directory:

          [standalone@localhost:9990 /] ls cadre-service                               subsystem                                  namespaces=[]                              release-version=iii.0.viii.Final                 deployment                                 system-property                            system=undefined                     running-style=NORMAL                         deployment-overlay                         launch-type=STANDALONE                     procedure-type=Server                        runtime-configuration-state=ok              extension                                  management-major-version=5                 product-name=WildFly Full                  schema-locations=[]                         interface                                  direction-micro-version=0                 product-version=11.0.0.Concluding               server-state=running                        path                                       management-minor-version=0                 profile-name=undefined                     suspend-country=RUNNING                       socket-binding-grouping                       name=matthews-mbp                          release-codename=Kenny                     uuid=ca421018-3df9-43e1-8b3f-ff843ebd38ee                  

The pwd command shows the current working directory:

          [standalone@localhost:9990 /] pwd /                  

The cd command will change the electric current directory. Often the directory will be a category similar subsystem and an example like undertow with an equals character in betwixt:

          [standalone@localhost:9990 /] cd subsystem=undertow [standalone@localhost:9990 subsystem=undertow] ls awarding-security-domain        server                             default-server=default-server      instance-id=${jboss.node.name}      buffer-cache                       servlet-container                  default-servlet-container=default  statistics-enabled=false            configuration                      default-security-domain=other      default-virtual-host=default-host                  

The help command shows a list of the available commands:

          [standalone@localhost:9990 subsystem=undertow] aid Usage:    jboss-cli.sh/jboss-cli.bat [--assist] [--version]                      [--bind=client_bind_address]                      [--controller=(controller_alias | [protocol://][host][:port])]                      [--connect] [--file=file_path]                      [--commands=command_or_operation(,command_or_operation)*]                      [--command=command_or_operation]                      [--user=username --password=password]                      [--backdrop=file_path]                      [--no-local-auth]                      [--mistake-on-interact]                      [--timeout=timeout]                      [--echo-control]                      [--command-timeout=timeout]   --help (-h)     - prints (this) basic description of the control line utility.  ...                  

The quit command will go out the CLI.

Tab completion

These commands likewise accept a number of options. The easiest way to encounter these options is to use tab complete. Hither I typed ls (the infinite on the cease is of import) and pressed tab to see what additional options are available:

          [standalone@localhost:9990 subsystem=undertow] ls --headers                    --resolve-expressions        application-security-domain  configuration                servlet-container             --help                       -50                           buffer-cache                 server                  

Performing operations

In any given directory at that place are a number of operations that tin can be performed. Operations showtime with the : character. Using tab completion nosotros can encounter the list of bachelor operations:

          [standalone@localhost:9990 http-listener=default] : add                         map-articulate                   read-attribute              read-children-types         remove                       list-add                    map-go                     read-attribute-group        read-operation-description  reset-statistics             list-clear                  map-put                     read-attribute-grouping-names  read-operation-names        undefine-attribute           list-get                    map-remove                  read-children-names         read-resource               whoami                       list-remove                 query                       read-children-resources     read-resources-description   write-attribute                  

The :read-operation-names operation shows the same list as the tab completion:

          [standalone@localhost:9990 http-listener=default] :read-operation-names {     "issue" => "success",     "result" => [         "add together",         "list-add",         "list-clear",         "list-get",         "listing-remove",         "map-clear",         "map-get",         "map-put",         "map-remove",         "query",         "read-attribute",         "read-attribute-group",         "read-attribute-group-names",         "read-children-names",         "read-children-resource",         "read-children-types",         "read-operation-description",         "read-operation-names",         "read-resource",         "read-resources-description",         "remove",         "reset-statistics",         "undefine-attribute",         "whoami",         "write-attribute"     ] }                  

Operations can be performed in the current directory (as nosotros have done in the instance to a higher place), or on a specific directory with a command like /:read-operation-names or /subsystem=undertow:read-functioning-names.

The :read-resource operation is a common way to listing the details of the current directory.

          [standalone@localhost:9990 http-listener=default] :read-resource {     "outcome" => "success",     "consequence" => {         "permit-encoded-slash" => false,         "allow-equals-in-cookie-value" => false,         "always-prepare-go along-alive" => true,         "buffer-pipelined-data" => false,         "buffer-puddle" => "default",         "certificate-forwarding" => false,         "decode-url" => truthful,         "disallowed-methods" => ["TRACE"],         "enable-http2" => true,         "enabled" => true,         "http2-enable-push" => true,         "http2-header-table-size" => 4096,         "http2-initial-window-size" => 65535,         "http2-max-concurrent-streams" => undefined,         "http2-max-frame-size" => 16384,         "http2-max-header-list-size" => undefined,         "max-buffered-asking-size" => 16384,         "max-connections" => undefined,         "max-cookies" => 200,         "max-header-size" => 1048576,         "max-headers" => 200,         "max-parameters" => 1000,         "max-post-size" => 10485760L,         "no-request-timeout" => 60000,         "proxy-address-forwarding" => false,         "read-timeout" => undefined,         "receive-buffer" => undefined,         "record-request-start-fourth dimension" => faux,         "redirect-socket" => "https",         "request-parse-timeout" => undefined,         "require-host-http11" => false,         "resolve-peer-address" => fake,         "rfc6265-cookie-validation" => imitation,         "secure" => false,         "send-buffer" => undefined,         "socket-binding" => "http",         "tcp-backlog" => 10000,         "tcp-keep-alive" => undefined,         "url-charset" => "UTF-8",         "worker" => "default",         "write-timeout" => undefined     } }                  

Individual attributes tin can be read using the :read-attribute performance:

          [standalone@localhost:9990 http-listener=default] :read-attribute(name=enabled) {     "event" => "success",     "result" => true }                  

Attributes can be written with the :write-aspect functioning:

          [standalone@localhost:9990 http-listener=default] :write-attribute(name=enabled, value=false) {"outcome" => "success"}                  

Attributes can be undefined with the :undefine-aspect performance:

          [standalone@localhost:9990 http-listener=default] :undefine-aspect(name=write-timeout) {"result" => "success"}                  

Special characters

To define a value with a space, wrap the string upwards in quotes:

          [standalone@localhost:9990 /] /system-property=test:write-attribute(proper name=value, value="value with infinite") {"outcome" => "success"} [standalone@localhost:9990 /] /system-holding=test:read-attribute(proper name=value) {     "outcome" => "success",     "result" => "value with space" }                  

To apply quotes, escape them with a backslash:

          [standalone@localhost:9990 /] /system-property=test:write-attribute(name=value, value="\"quoted value with space\"") {"outcome" => "success"} [standalone@localhost:9990 /] /system-property=test:read-attribute(name=value) {     "upshot" => "success",     "outcome" => "\"quoted value with infinite\"" }                  

Backslashes are themselves escaped with a backslash:

          [standalone@localhost:9990 /] /system-belongings=exam:write-attribute(proper noun=value, value="\"quoted value with infinite and a backslash \\\"") {"effect" => "success"} [standalone@localhost:9990 /] /arrangement-holding=examination:read-attribute(name=value) {     "outcome" => "success",     "result" => "\"quoted value with infinite and a backslash \\\"" }                  

Reloading the server

Changing some settings requires the server to be reloaded. You can check the country of the server past reading the server-state attribute in the root directory. In this example, we accept some settings that crave a reload:

          [standalone@localhost:9990 /] :read-attribute(proper noun=server-state) {     "event" => "success",     "result" => "reload-required",     "response-headers" => {"process-state" => "reload-required"} }                  

The :reload operation will reload the server:

          [standalone@localhost:9990 /] :reload {     "consequence" => "success",     "result" => undefined }                  

Batching operations

Some operations in WildFly need to be run as an diminutive unit of measurement, or you may want all commands to succeed or fail as one. The batch and run-batch commands provide this functionality.

When in batch mode, a # character volition announced in the prompt.

          [standalone@localhost:9990 /] batch [standalone@localhost:9990 / #] /subsystem=undertow/server=default-server/http-listener=default:undefine-attribute(name=write-timeout) [standalone@localhost:9990 / #] /subsystem=undertow/server=default-server/http-listener=default:write-attribute(name=enabled, value=fake) [standalone@localhost:9990 / #] run-batch The batch executed successfully                  

The discard-batch command will discard any batched commands and exit the batch mode:

          [standalone@localhost:9990 /] batch [standalone@localhost:9990 / #] /subsystem=undertow/server=default-server/http-listener=default:write-attribute(name=enabled, value=imitation) [standalone@localhost:9990 / #] discard-batch [standalone@localhost:9990 /]                  

The list-batch command will show the pending batched commands, and the clear-batch command volition clear any batched commands but exit yous in batched mode:

          [standalone@localhost:9990 /] batch [standalone@localhost:9990 / #] /subsystem=undertow/server=default-server/http-listener=default:write-attribute(name=enabled, value=false) [standalone@localhost:9990 / #] list-batch #1 /subsystem=undertow/server=default-server/http-listener=default:write-attribute(proper name=enabled, value=faux) [standalone@localhost:9990 / #] articulate-batch [standalone@localhost:9990 / #] list-batch The batch is empty. [standalone@localhost:9990 / #] discard-batch                  

For more data on using batches in WildFly, see CLI Batch Way.

Backing up the configuration

You may wish to backup the electric current configuration before making any changes. This tin can as be done with the :take-snapshot functioning.

The result of this operation tells you lot where the fill-in was saved:

          [standalone@localhost:9990 /] :take-snapshot {     "outcome" => "success",     "issue" => "C:\\Users\\matth\\Downloads\\wildfly-11.0.0.Final\\wildfly-11.0.0.Terminal\\standalone\\configuration\\standalone_xml_history\\snapshot\\20171108-082107378standalone.xml" }                  

Running CLI scripts

CLI commands tin can be added to a script file and run non-interactively.

For example, save this script to a file chosen test.cli:

          connect batch /subsystem=undertow/server=default-server/http-listener=default:undefine-attribute(name=write-timeout) /subsystem=undertow/server=default-server/http-listener=default:write-attribute(proper noun=enabled, value=faux) run-batch                  

It can then be run using the --file command line choice:

          ./jboss-cli.sh --file=exam.cli                  

In this test script, we have continued to the WildFly case from inside the script with the connect command instead of passing the --connect command line option.

To disable the Press whatever fundamental to go on ... prompt when you run the jboss-cli.bat file in Windows, set the NOPAUSE environment variable to true:

          PS C:\Users\matth\Downloads\wildfly-xi.0.0.Final\bin> $env:NOPAUSE="truthful" PS C:\Users\matth\Downloads\wildfly-11.0.0.Final\bin> .\jboss-cli.bat --connect [standalone@localhost:9990 /] quit PS C:\Users\matth\Downloads\wildfly-11.0.0.Final\bin>                  

Flow control statements

CLI supports menstruation control statements like if/else and endeavor/catch/finally.

For example, you can add the following code to a CLI script, and it will set the system belongings test to truthful if it has not been defined:

          if (consequence != success) of /system-property=exam:read-resources     /system-property=test:add(value=true) finish-if                  

Yous can run the same commands in an interactive mode also:

          [standalone@localhost:9990 /] if (event != success) of /system-property=test:read-resource [standalone@localhost:9990 /] /system-property=test:add(value=true) [standalone@localhost:9990 /] end-if {"outcome" => "success"}                  

The try/take hold of/finally flow command works much the aforementioned as in Java. The following will endeavor to add together a information source and volition remove and add the data source if there was an exception. Finally, the data source is enabled:

          effort   /subsystem=datasources/data-source=myds:add(connectedness-url=thirty,jndi-name=java:/myds,driver-name=h2) catch   /subsystem=datasources/information-source=myds:remove   /subsystem=datasources/information-source=myds:add together(connection-url=xxx,jndi-proper name=java:/myds,commuter-name=h2) finally   /subsystem=datasources/data-source=myds:enable end-try                  

Multiline commands

Commands tin be carve up over multiple lines past ending each line with a \ grapheme:

          [standalone@localhost:9990 /] /subsystem=datasources/data-source=myds:add( \ >   connection-url=30, \ >   jndi-name=java:/myds, \ >   commuter-name=h2) {"outcome" => "success"}                  

Running the CLI GUI

The CLI has a GUI mode which provides a file browser like interface for navigating around the WildFly settings directory structure:

          ./jboss-cli.sh --gui                  

Conclusion

In this post, we took a high level expect at how the CLI works and what you can practise with it. You can detect more resources on the JBoss Wiki which goes into more item and provides examples of authoritative tasks.
