CentOS: Difference between revisions

[http://www.centos.org CentOS] is an Enterprise-class Linux Distribution derived from sources freely provided to the public by [http://www.redhat.com/ RedHat]. CentOS versions are maintained by a group of volunteers who supply 100% compatible re-compilations from the latest client, server and (for RHEL7) workstation and compute node source-code SRPMS of RHEL5, RHEL6 and RHEL7 [ftp://ftp.redhat.com/pub/redhat/linux/enterprise available], with all security fixes, bugfixes and feature enhancements. The CentOS mailing list is also available from the public newsserver news.gmane.org (the name is gmane.linux.centos.general; posting is allowed).

Version 5 is based on kernel 2.6.18 and is still suitable for computing in X-ray crystallography. Maintenance updates to this version are planned to be made available until [http://www.zdnet.com/blog/open-source/red-hat-extends-red-hat-enterprise-linux-lifecycle-to-ten-years/10237 Mar 31st, 2017].   

 

32bit and 64bit versions exist for a number of platforms; most notably for Intel and compatible processors. On PC-type hardware, one should probably choose the 64bit version if the machine has more than 2GB of memory.

The best 3rd-party software repository to be be used with CentOS is [http://fedoraproject.org/wiki/EPEL EPEL]. On CentOS, you can install EPEL by running <code>yum install epel-release</code>. The package is included in the CentOS Extras repository, enabled by default. Usage: e.g. to make your Windows partition read/writable to your CentOS installation, just run <code>yum -y install ntfs-3g</code>" after enabling EPEL.

There is the [http://elrepo.org/tiki/tiki-index.php ElRepo] repository for hardware kernel modules. Explanation at [http://dag.wieers.com/blog/improved-rhel-centos-and-scientific-linux-hardware-support].

This is very useful e.g. recent hardware that is not properly supported by the kernel, e.g. for the  RTL8111/8168B Ethernet controller found on recent motherboards. Also, the [[NVidia]] driver is now provided by ElRepo.

# If you want to "configure" CCP4 using --with-x , you need "yum groupinstall 'X Software Development' "

# Additionally you may need to install g++, gfortran, ncurses-devel and python-devel RPMs for compilation ("yum install gcc gcc-g++ gcc-gfortran ncurses-devel python-devel"). (You could even choose to "yum install gcc44 gcc44-g++ gcc44-gfortran" which will give you the 4.4 version instead of 4.1.2 .  

# make sure to choose the Tcltk package when you download CCP4; this will configure and install blt, bltwish, and tcl/tk together with the main part of CCP4.

# Following Tim Grüne's advice, comment out the modification of MANPATH in $CCP4/include/ccp4.setup .

 

Make sure to include the binary Tcltk distribution when you download CCP4. This works fine on 64bit machines provided you installed the required 32bit libraries (see below).
