The Scisoft Team, January 2015 (scihelp@eso.org) Installing Scisoft 8 on Fedora Core 20 ======================================= There are two methods to install Scisoft 8; these are described below in order of preference (best first), together with the pros and cons of each method. Allocate disk space for SCISOFT. -------------------------------- Scisoft occupies 9Gbytes in disk. It will be installed in your system in a directory called /scisoft. Make sure your root filesystem allocates this diskspace, otherwise create a soft link to another free disk area. Example: mkdir /mydisk/scisoft ln -s /mydisk/scisoft /scisoft Method #1 Installing from the online yum repository --------------------------------------------------- Pros: * your Scisoft installation can automatically be kept aligned with the latest available bugfixes for this Scisoft release * you can install all of Scisoft or only the parts you want Cons: * requires Fedora Core 20 Procedure: 1) If you have a previous installation of Scisoft then back it up and remove it using a method appropriate to it was installed (e.g. if you used 'yum' to install it now use 'yum' to remove it). 2) As root create /etc/yum.repos.d/scisoft.repo containing: [scisoft] name=Scisoft baseurl=ftp://ftp.eso.org/scisoft/scisoft8/linux/fedora/20/x86_64 gpgcheck=0 enabled=1 3) As root run: yum clean all yum install scisoft8-\* and when prompted, check the list of packages about to be installed looks sensible, and then allow yum to start installing the packages by pressing 'y'. Method #2 Installing from RPMs ------------------------------ Pros: * you can install all of Scisoft or only the parts you want Cons: * requires Fedora Core 20, or that some dependencies are overridden using rpm's '--nodeps' option Procedure: 1) Download all RPMs at ftp://ftp.eso.org/scisoft/scisoft8/linux/fedora/20/x86_64/, or copy them from the Scisoft DVD and save them to a directory, which we will call . 2) If you have a previous installation of Scisoft then back it up and remove it using a method appropriate to it was installed (e.g. if you used 'yum' to install it now use 'yum' to remove it). 3) As root, run: rpm -ihv /*.rpm Uninstalling Scisoft 8 on Fedora Core 20 ======================================== There are two methods to uninstall Scisoft 8; you should use the method which corresponds with the method you chose for installing Scisoft 8.
