Installing Git on a shared hosting account is simple, the installation is fast and like most things Git, it just works.

This is a basic install without documentation. My main goal is to be able to push changes from remote repositories into the hosted repository, which also serves as the source directory of the live website. Like this.

Prerequisites

The only two things you absolutely must have are shell access to the account and permission to use GCC on the server. Check both with the following command:

$ ssh joe@webserver 'gcc --version'
gcc (GCC) 4.1.2 20080704 (Red Hat 4.1.2-50)
[...]

If GCC replies with a version number, you should be able to install Git. SSH into your server and let’s get started!

If you see something like /usr/bin/gcc: Permission denied you don’t have access to the GCC compiler and will not be able to build the Git binaries from source. Find another hosting company.

Update your $PATH

None of this will work if you don’t update the $PATH environment variable. In most cases, this is set in .bashrc. Using .bashrc instead of .bash_profile updates $PATH for interactive and non-interactive sessions–which is necessary for remote Git commands. Edit .bashrc and add the following line:

export PATH=$HOME/bin:$PATH

Be sure ‘~/bin’ is at the beginning since $PATH is searched from left to right; to execute local binaries first, their location has to appear first. Depending on your server’s configuration there could be a lot of other stuff in there, including duplicates.

Double-check this by sourcing the file and echoing $PATH:

$ source ~/.bashrc
$ echo $PATH
/home/joe/bin:/usr/local/bin:/bin:/usr/bin

Verify that the remote path was updated by sending a remote command like this (from another connection):

$ ssh joe@webserver 'echo $PATH'
/home/joe/bin:/usr/local/bin:/bin:/usr/bin

Note: Previous iterations of this page installed into the ~/opt directory. Following current Git conventions, I’m now installing into the default ~/bin.

Installing Git

SSH into your webserver. I created a source directory to hold the files and make cleanup easier:

$ cd
$ mkdir src
$ cd src

Grab the most recent source tarball from Github. When this post was updated, the current Git release was version 1.7.10.1:

$ curl -LO https://github.com/git/git/tarball/v1.7.10.1

Untar the archive and cd into the new directory:

$ tar -xzvf v1.7.10.1
$ cd git-git-9dfad1a

By default, Git installs into ~/bin which is perfect for shared hosting. Earlier versions required adding a prefix to the configure script (like this), but none of that is necessary anymore. If you do need to change the install location of Git, just specify a prefix to the Make command as described in Git’s INSTALL file.

With all that taken care of, installation is simple:

$ make
$ make install
[lots of words...]

That should be it, check your installed version like this:

$ git --version
git version 1.7.10.1

It's now safe to delete the src folder containing the downloaded tarball and source files.

My preferred shared hosting providers are A2 Hosting and WebFaction.

Media Temple doesn’t yet support svn:// access to Subversion repositories, only svn+ssh://. So, having been pushed, I finally decided to make my life easier with SSH key pairs.

The best tutorial I found was Allan Odgaard’s: Subversion support and ssh key pairs. Without ssh key pairs, all the fantastic Subversion integration in TextMate won’t work with svn+ssh:// repositories.

However there’s one crucial piece of information missing from that: Permissions.

If access to the SSH configuration files is not properly assigned, the ssh pair won’t work. No meaningful errors at connect time, just silent, infuriating failure.

The ~/.ssh directory permissions need to be set to 0700 and the authorized_keys file needs to be set to 0600:

chmod 0600 ~/.ssh/authorized_keys
chmod 0700 ~/.ssh

If group or world have write access to authorized_keys, key pair authentication will fail.
