Install it by:
sudo yum install centos-release-scl
sudo yum install devtoolset-4
The first command installs and enables Software Collections Repository on your CentOS machine. That repository provides the devtoolset package.

This does not work on CentOS 6.10 anymore.
Those are the ones available without jumping through hoops:
[misp@misp-centos6 ~]$ yum search devtoolset |grep devtoolset|awk {'print $1'} |cut -f 1,2 -d\-|sort|uniq

devtoolset-6
devtoolset-6.x86_64
devtoolset-7
devtoolset-7.x86_64
While Devtoolset-3 and 4 are located on the Centos mirror site, yum will not be able to find them as they were not included in the repodata on the site. These were probably excluded because they are EOL (end-of-life), and have dependency bugs (Bug 1410152). Try using the older Devtoolset-3 packages here, which do not have the dependency issues:
https://copr.fedorainfracloud.org/coprs/rhscl/devtoolset-3/
If you really want the packages from the centos.org site, I went with wget to download all the RPMs, then recreated a local yum repo. However, you'll see the dependency issues and yum install devtoolset-3 will fail.
$ wget -r -p -e robots=off --directory-prefix="/mnt/local-devtoolset3-repo" --recursive --no-clobber --no-parent http://mirror.centos.org/centos/6/sclo/x86_64/rh/devtoolset-3/
$ sudo yum install createrepo
$ cd /mnt/local-devtoolset3-repo
$ createrepo --database .
There was no DTS 5 release. It was skipped to align the DTS version with the GCC major release, once GCC switched to a yearly increasing version number.
DTS versions 3 and 4 are available from the centos-release-scl repository.
