How To Install JuliaLang on CentOS 7

To Install JuliaLang on CentOS 7

Julia, commonly called  JuliaLang, is a programming language for numerical computing. Julia is as fast as C but it doesn’ t forfeit the readability. Therefore, we can decrease the running time of our programs in addition to the evolution time. It is so simple to install JuliaLang on CentOS7 and this tutorial covers the ground on the same process. 

 

Installing JuliaLang

First, you need to ensure that your system is up-to-date, and for that you need to use the following command.  

[root@linuxhelp ~]# yum clean all
Loaded plugins: fastestmirror, langpacks
Cleaning repos: base extras updates
Cleaning up everything
Maybe you want: rm -rf /var/cache/yum, to also free up space taken by orphaned data from disabled or removed repos
Cleaning up list of fastest mirrors

 

And then you need to run the following command.  

[root@linuxhelp ~]# yum -y install epel-release
Loaded plugins: fastestmirror, langpacks
base                                                                                                                  | 3.6 kB  00:00:00

Complete!


You should now install the required packages by making use of the following command.  

 [root@linuxhelp ~]# yum-config-manager --add-repo https://copr.fedorainfracloud.org/coprs/nalimilan/julia/repo/epel-7/nalimilan-julia-epel-7.repo
Loaded plugins: fastestmirror, langpacks
adding repo from: https://copr.fedorainfracloud.org/coprs/nalimilan/julia/repo/epel-7/nalimilan-julia-epel-7.repo
grabbing file https://copr.fedorainfracloud.org/coprs/nalimilan/julia/repo/epel-7/nalimilan-julia-epel-7.repo to /etc/yum.repos.d/nalimilan-julia-epel-7.repo
repo saved to /etc/yum.repos.d/nalimilan-julia-epel-7.repo

 

You shall now proceed with the installation of Julia by making use of the following command.
