Before you begin
Before you start the server, note the following:
config-validation.xmlfile in the
<PRODUCT_HOME>/repository/conf/etcdirectory contains a list of recommended system parameters, which are validated against your system when the server starts. See Configuring config-validation.xml for details on modifying these parameters before starting the server.
- The Management Console uses the default HTTP-NIO transport, which is configured in the
catalina-server.xmlfile in the
<PRODUCT_HOME>/repository/conf/tomcatdirectory. This transport must be properly configured in this file for the Management Console to be accessible.
Changing the default configurations
After you download the product, the default configurations in the product have to be changed according to your requirement, before you start the server. See the following topics for details:
- Changing the Default RSS Configuration
- Changing the Default Cassandra Configuration
- Changing the Default HDFS Configuration
Starting the server
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
To start and stop the server in the background mode of Linux, run
wso2server.sh start and
wso2server.sh stop commands.
- Open a command prompt:
- On Windows, choose Start -> Run, type
cmdat the prompt, and press Enter.
- On Linux/Solaris, establish a SSH connection to the server or log in to the text Linux console.
Execute one of the following commands, where
<SS_HOME> is the directory where you installed the product distribution:
- On Windows:
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:
<PRODUCT_HOME>\bin\wso2server.bat --run -DworkerNode
- On Linux/Solaris:
sh <PRODUCT_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 <PRODUCT_HOME>/bin/wso2server.sh -help.
The operation log appears. When the product server is running, the log displays the message "WSO2 Carbon started in 'n' seconds".
Running the management console
Once the server has started, you can run the Management Console by opening a Web browser and typing in the management console's URL. The URL is displayed as the last line in the start script's console and log. For example:
The URL should be in the following format:
You can use this URL to access the Management Console on this computer from any other computer connected to the Internet or LAN. When accessing the Management Console from the same server where it's installed, you can type "localhost" instead of the IP address:
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 product. 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 in the top right corner of that page , or click the Docs link to open this documentation for full information on managing the product.
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 belongs to the given organization.
If you leave the Management Console unattended, the session will time out. The default timeout value is 15 minutes, but you can change this in the
<SS_HOME>/repository/conf/tomcat/carbon/WEB-INF/web.xml file as follows:
Restricting Access to the Management Console and Web Applications:
You can restrict access to the management console of your product by binding the management console with selected IP addresses. Note that you can either restrict access to the management console only, or you can restrict access to all web applications in your server as explained below.
To control access only to the management console, add the IP addresses to the
<PRODUCT_HOME>/repository/conf/tomcat/carbon/META-INF/context.xmlfile as follows:
RemoteAddrValveTomcat 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.xmlfile as follows:
RemoteAddrValveTomcat 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.xmlfile (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.
The following example from a web.xml file illustrates how access to the management page (
/carbon/admin/login.jsp) is granted only to one IP address:
<PRODUCT_HOME>/repository/conf/tomcat/catalina-server.xmlfile 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.
Stopping the server
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.
