To run WSO2 DAS, you start the DAS server at the command line. You can then run the Management Console application to configure and manage the product. This page describes how to run the product in the following sections:

Info

The Management console uses the default HTTP-NIO transport, which is configured in the catalina-server.xml file in the <DAS_HOME>/repository/conf/tomcat directory. This transport must be properly configured in this file for the Management console to be accessible.

...

To start the server, you run the script wso2server.bat (on Windows) or wso2server.sh (on Linux/Solaris) from the bin folder. Alternatively, you can install and run the server as a Windows service.

Info

To start and stop the server in the background mode of Linux, run wso2server.sh start and wso2server.sh stop commands.

  1. Open a command prompt:
    • On Windows, choose Start -> Run, type cmd at the prompt, and press Enter.
    • On Linux/Solaris, establish a SSH connection to the server or log in to the text Linux console.
  2. Execute one of the following commands, where <DAS_HOME> is the directory where you installed the DAS distribution:
    • On Windows: <DAS_HOME>/bin/wso2server.bat --run
    • On Linux/Solaris: sh <DAS_HOME>/bin/wso2server.sh

      Info

      If you want to provide access to the production environment without allowing any user group (including admin) to log into the management console, execute one of the following commands.

      • On Windows: <DAS_HOME>\bin\wso2server.bat --run -DworkerNode
      • On Linux/Solaris: sh <DAS_HOME>/bin/wso2server.sh -DworkerNode

      If you want to check any additional options available to be used with the startup commands, type -help after the command, such as: 

      sh <DAS_HOME>/bin/wso2server.sh -help.

The operation log appears. When the DAS server is running, the log displays the message "WSO2 Carbon started in 'n' seconds."

...

Once the server has started, you can run the Management Console by opening a Web browser and typing in the management console's URL. You can find the URL in the start script's log. For example:

product management console URLImage Removed

The URL should be in the following format: https://<Server Host>:9443/carbon

...

Tip

The Management Console URL can be changed by modifying the value of the MgtHostName in the <DAS_HOME>/repository/conf/carbon.xml file.

Code Block
languagexml
<MgtHostName>localhost</MgtHostName>

At the sign-in screen, sign in to the Management Console using admin as both the username and password. You can then use the Management Console to manage the DAS. The tabs and menu items in the navigation pane on the left may vary depending on the features you have installed. To view information about a particular page, click the Help link at the top right corner of that page , or click the Docs link to open this documentation for full information on managing the DAS.

If you leave the Management Console unattended for a defined time, its login session will time out. The default timeout value is 15 minutes, but you can change this in <DAS_HOME>/repository/conf/tomcat/carbon/WEB-INF/web.xml file as follows:

Code Block
languagehtml/xml
<session-config>
   <session-timeout>15</session-timeout>
</session-config>

When the Management Console Sign-in page appears, the web browser will typically display an "insecure connection" message, which requires your confirmation before you can continue.

The Management Console is based on HTTPS protocol, which is a combination of HTTP and SSL protocols. This protocol is generally used to encrypt the traffic from the client to server for security reasons. The certificate it works with is used for encryption only, and does not prove the server identity, so when you try to access the Management Console, a warning of untrusted connection is usually displayed. To continue working with this certificate, some steps should be taken to "accept" the certificate before access to the site is permitted. If you are using the Mozilla Firefox browser, this usually occurs only on the first access to the server, after which the certificate is stored in the browser database and marked as trusted. With other browsers, the insecure connection warning might be displayed every time you access the server.

This scenario is suitable for testing purposes, or for running the program on the company's internal networks. If you want to make the Management Console available to external users, your organization should obtain a certificate signed by a well-known certificate authority, which verifies that the server actually has the name it is accessed by and that this server actually belongs to the given organization.

...

titleRestricting Access to the Management Console and Web Applications:

...

To control access only to the management console, add the IP addresses to the <PRODUCT_HOME>/repository/conf/tomcat/carbon/META-INF/context.xml file as follows:

 

<Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="<IP-address-01>|<IP-address-02>|<IP-address-03>"/>

 

The RemoteAddrValve Tomcat valve defined in this file will only apply to the Carbon management console, and thereby all outside requests to the management console will be blocked. 

...

To control access to all web applications deployed in your server, add the IP addresses to the <PRODUCT_HOME>/repository/conf/context.xml file as follows:

 

<Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="<IP-address-01>|<IP-address-02>|<IP-address-03>"/>

 

The RemoteAddrValve Tomcat valve defined in this file will apply to each web application hosted on the Carbon server. Therefore, all outside requests to any web application will be blocked.

You can also restrict access to particular servlets in a web application by adding a Remote Address Filter to the web.xml file (stored in the<PRODUCT_HOME>/repository/conf/tomcat/ directory), and by mapping that filter to the servlet url. In the Remote Address Filter that you add, you can specify the IP addresses that should be allowed to access the servlet.

...

 

<filter>
    <filter-name>Remote Address Filter</filter-name>
    <filter-class>org.apache.catalina.filters.RemoteAddrFilter</filter-class>
        <init-param>
            <param-name>allow</param-name>
            <param-value>127.0.01</param-value>
        </init-param>
</filter>
 
<filter-mapping>
    <filter-name>Remote Address Filter</filter-name>
    <url-pattern>/carbon/admin/login.jsp</url-pattern>
</filter-mapping>
Note: Any configurations (including valves) defined in the <PRODUCT_HOME>/repository/conf/tomcat/catalina-server.xml file applies to all web applications and is globally available across server, regardless of host or cluster. See the official Tomcat documentation for more information about using remote host filters.

 

...

To stop the server, press Ctrl+C in the command window, or click the Shutdown/Restart link in the navigation pane in the Management Console.
