Info

Installing and Configuring on Unix Upon startup, Tomcat will parse the server.xml file and create objects based on the content of the file. A single Connector element specification in the server.xml file will hence cause Tomcat to create a Connector object. If you then update the file with another Connector element specification, it will automatically trigger the creation of another instance of the Connector. This is how the above change creates two connectors listening on port 8080 and 8081 respectively. You only have one container though. The connectors create a request and response object for each incoming HTTP request and pass it to the container. 4. Then, save the file. 5. Finally, restart the Tomcat server. 2.4 Installing the eG Manager on Privileged Ports On Unix, all ports below 1024 are privileged ports. Only super users or users authorized to access this port will be able to bind to these ports. If you wish to have the eG manager listening on a privileged port, you will need to follow the procedure listed below. When the eG manager is installed on Solaris 10 or higher, you can install the eG manager and have it configured to listen to a privileged port (e.g., 80 or 443). Before starting the manager, login to the Solaris server as a super-user and run the following command to instruct the operating system to allow the eG user to open a privileged port: usermod -K defaultpriv=basic,net_privadd Log out and log back in as the eG user, and then, start the eG manager. On Linux systems, follow the steps below: Install the eG manager on a port higher than 1024 – e.g., 7077. Use the iptables command to set up redirection from a privileged port to the port that the eG manager is using. For example, suppose you have installed the eG manager on port 7077 with SSL support and you would like the manager to listen on port 443; then, do the following: o Start the Manager on port 7077 using the start_manager command. o Execute the iptables command as below on the Linux system hosting the eG manager. These commands should be executed from a super-user account. iptables -t nat -A OUTPUT –d -p tcp --dport 443 -j REDIRECT --to-ports 7077 iptables -t nat -A PREROUTING -d -p tcp --dport 443 -j REDIRECT --to-ports 7077 o Once these commands are executed, the eG manager will be accessible on port 443 as well. 41
Installing and Configuring on Unix Entries configured using iptables are lost when the manager reboots. To save the iptables configuration, do the following: o Run the following command as root user: /sbin/iptables-save > /opt/egurkha/iptables.fw o Edit the file /etc/rc.local and append the following line to this file /sbin/iptables-restore < /opt/egurkha/iptables.fw Now, even if the eG manager system is rebooted, the iptables configuration is restored. 2.5 Starting the Manager To start the manager, execute the command /opt/egurkha/bin/start_manager. The following message appears when the manager starts successfully: $ ./start_manager 5 Starting the eG manager components ... Please wait ... Starting the admin components . . . Starting the monitor components . . . Starting the eghelp components . . . Initializing the eG manager . . . ****************************************************************** The eG manager 5 has been started successfully! ****************************************************************** If the manager fails to start, the following message appears. ************************************************************************** Failed to start the eG manager! ... Possible reasons for this could be: (i) Your license located in the file: /opt/egurkha/bin/license may be invalid... Please check the file "/opt/egurkha/manager/logs/error_log" for details. (ii) You may not have permissions to start the eG manager... Please check the permissions for the directory "/opt/egurkha/manager". *************************************************************************** 2.6 Increasing the Memory of the eG Manager Process The eG manager runs as a Java process. The maximum heap memory that can be allocated to a 32-bit eG manager process is limited to 1.5 GB. The maximum heap memory allocation to a 64-bit eG manager process on the other hand, is limited to 3 GB. Where a large number of components are to be monitored, you may want to allocate more memory heap to the eG manager process. On a Unix manager, follow the steps below to modify the heap memory allocation: 1. Login to the eG manager host. Edit the catalina.sh file in the /opt/egurkha/manager/tomcat/bin directory. 42
