If you have multiple servers with similar or identical configurations (such as nodes in a cluster), it’s often difficult to make sure the contents and configuration of those servers are identical. It’s even more difficult when you need to make configuration modifications from the command line, knowing you’ll have to execute the exact same command on a large number of systems . In this tutorial we will see some tools to execute one command on multiple remote servers using ssh.First you need to make sure you have ssh installed in your machine or you can install using the following command

In previous chapters we have covered the steps necessary to install and configure Xen and Xen based guest operating systems. This chapter is dedicated to explaining the xm tool, and how it can be used to manage guest operating systems from the command-line.

Contents * 1 xm Command-line vs xm Shell * 2 Listing Guest System Status * 3 Starting a Xen Guest System * 4 Connecting to a Running Xen Guest System * 5 Shutting Down a Guest System * 6 Pausing and Resuming a Guest System * 7 Suspending and Resuming a Guest OS * 8 Saving and Restoring Xen Guest Systems * 9 Rebooting a Guest System * 10 Configuring the Memory Assigned to a Xen Guest OS * 11 Migrating a Domain to a Different Host

This article explains how you can install and configure apache2-mpm-peruser on a Debian Etch server. apache2-mpm-peruser is an MPM (Multi-Processing Module) for the Apache 2 web server, very similar to apache2-mpm-itk, but faster (almost as fast as apache2-mpm-prefork). mpm-peruser allows you to run each of your vhosts under a separate UID and GID - in short, the scripts and configuration files for one vhost no longer have to be readable for all the other vhosts. It is based on metuxmpm, a working implementation of the perchild MPM. The result is a sane and secure web server environment for your users, without kludges like PHP's safe_mode.
