Installing Mantid Via Yum

From MantidProject

On RHEL5 it is now possible to install Mantid and all the requied RPMs via the ISIS yum prepository. Other Linux systems will be added in due course. If you wish to rebuild Mantid from source, download the RHEL5 Source RPMs (release, nightly build) and also install any additional libraries.

Setup

RHEL5

Important note: following these procedures will update some default RHEL5 packages with newer versions on your system. For a full list of possible packages see the RHEL5 Source RPMs (release, nightly build). Nothing will be modified on your system until you type yum install Mantid and, at that point, you will be given the list of changed packages and have the option to decide whether to proceed.

First you need to enable the Extra Packages for Enterprise Linux (EPEL) by installing the relevant rpm

Next you need to create the file /etc/yum.repos.d/isis-rhel.repo with the following content

[isis-rhel]
name=ISIS Software Repository for Redhat Enterprise Linux $releasever - $basearch
baseurl=http://yum.isis.rl.ac.uk/rhel/$releasever/$basearch
failovermethod=priority
enabled=1
gpgcheck=0

[isis-rhel-debuginfo]
name=ISIS Software Repository for Redhat Enterprise Linux $releasever - $basearch - Debug
baseurl=http://yum.isis.rl.ac.uk/rhel/$releasever/$basearch/debug
failovermethod=priority
enabled=1
gpgcheck=0

[isis-rhel-source]
name=ISIS Software Repository for Redhat Enterprise Linux $releasever - $basearch - Source
baseurl=http://yum.isis.rl.ac.uk/rhel/$releasever/SRPMS
failovermethod=priority
enabled=0
gpgcheck=0

If you want to automatically install nightly development builds, also create /etc/yum.repos.d/isis-rhel-testing.repo with the following content

[isis-rhel-testing]
name=ISIS Software Repository for Redhat Enterprise Linux $releasever - $basearch
baseurl=http://yum.isis.rl.ac.uk/rhel/testing/$releasever/$basearch
failovermethod=priority
enabled=1
gpgcheck=0

[isis-rhel-testing-debuginfo]
name=ISIS Software Repository for Redhat Enterprise Linux $releasever - $basearch - Debug
baseurl=http://yum.isis.rl.ac.uk/rhel/testing/$releasever/$basearch/debug
failovermethod=priority
enabled=1
gpgcheck=0

[isis-rhel-testing-source]
name=ISIS Software Repository for Redhat Enterprise Linux $releasever - $basearch - Source
baseurl=http://yum.isis.rl.ac.uk/rhel/testing/$releasever/SRPMS
failovermethod=priority
enabled=0
gpgcheck=0

Finally you need to edit /etc/yum.conf

If you are based at Rutherford lab and do not already have a proxy set, add the line:

proxy=http://wwwcache.rl.ac.uk:8080

If, when you do a yum update, you get errors about mismatched metadata checksums etc, also add the line

http_caching=packages
