How To Install PowerShell On Linux

How To Install PowerShell On Linux

Earlier this month Microsoft announced that PowerShell had been open sourced and would be available for use in Linux. As a result of this, PowerShell is now available for Ubuntu 14.04 and 16.04, CentOS/RHEL 7, and macOS 10.11.

If your first thought is along the lines of “who would use this abomination?”, then you’re in good company. My best thought at who this is targeted towards is the Windows system administrator that needs to be able to manage Linux systems as they are likely already quite familiar with PowerShell and perhaps unwilling to change.

How To Upgrade/Migrate Ejabberd XMPP Server On Linux

Migrate Or Upgrade Ejabberd XMPP Server In Linux

In this example we will be upgrading from an older instance of the ejabberd-15.04 XMPP server to the current latest version ejabberd-16.06. Operating system specific packages such as RPM and DEB files were not provided until ejabberd-15.06, so our existing instance was not installed with the RPM file but instead from the binary file, meaning there is no existing ejabberd RPM installed for us to simply upgrade.

While this upgrade is taking place on the same server, these steps can also be used to perform a migration from one server to another with a fresh installation of ejabberd, as the new version will install to a new directory.
