RE: upgarding GIT

Hi Todd

Thanks for replying, below is my current install information

Current ( STASH and GIT are installed on the same server ):

STASH ( BitBucket ) = 3.9.2
Git = 2.0.4 ( installed from tar Ball and not from an RPM as the RPM was too old.
Centos = 6.6

Required:

BitBucket = 5.2
Git = 2.2 + and above

https://confluence.atlassian.com/bitbucketserver/supported-platforms-776640981.html

As you can see my version of git is not supported with the current version of bitbucket. I will have to perform a two stage upgrade anyway as the version of STASH I am running cannot be upgraded directly to bitbucket 5.2 as well.

Is there an easy way just to install a higher support version of git like 2.9 on the same server and then move all the repos and basically everything across. Can you install another TAR ball later version on top of another git , so it's like overwriting it. 


Kind regards,

Which release of CentOS are you using James?  And what git version is required for the Atlassian Stash (which is now called Bitbucket) release you're trying to use?  IIRC, they support as far back as git 1.8?

Indeed.  (But I'm biased because I would never, ever install software via 'sudo make install' on anything other than a throw-away test
instance.)

The one problem folks run into on CentOS/RHEL is that the versions may be somewhat old.  CentOS/RHEL 6 ships with git 1.7.1, for instance. 
CentOS/RHEL 7 is only a little newer, with git 1.8.3.  There are "software collections" which provide git 1.9¹ and 2.9², but personally I've never liked using software collections for software that I need to integrate with other tools.

For users of CentOS/RHEL who want to run the current git release in a packaged form, the Fedora git package maintainers take care to ensure that the Fedora packages can be built for the current supported releases of CentOS/RHEL (6 & 7 at the moment).  Grabbing the current code and/or srpm from Fedora should (almost³) always build cleanly using the mock build tool for CentOS/RHEL.

I also try to keep a semi-official COPR repo up to date, here:

    https://copr.fedorainfracloud.org/coprs/g/git-maint/git/

(Even as the primary maintainer of that repo, I'd still suggest that it's wise to either mirror it locally or rebuild the srpm's in your own infrastructure, to ensure that if the copr service is ever down you can reinstall important systems.)

³ Right now, there's a slight issue building the current git for
  CentOS 7 because RHEL 7.4 moved the pcre2 package from EPEL into
  RHEL and CentOS 7.4 is not yet built.  The Fedora packages are
  built against pcre2 now (thanks Ævar ;).  So for a few weeks it
  won't be possible to build them for CentOS 7 without a minor change.
