Instructions for setting up git server on Synology Diskstation

Configure Synology NAS as Git Server

Instructions for setting up a git server on a Synology NAS with Diskstation. Specifically, I am using a DS414 with DSM 5.0.

Set Up User and Folder

• Create user gituser via Diskstation interface (with File Station and WebDAV privilages)
• Add new shared folder called git (located at /volume1/git) with read/write access for gituser and admin. This folder will hold all the repos.
• Install Git Server package via Diskstation
• Open Git Server and allow gituser permissions
• Enable SSH access on Diskstation (Control Panel > Terminal & SNMP > Enable SSH Service)

Configure SSH Access

• create ~/.ssh folder for gituser on server

ssh [email protected]
mkdir /volume1/homes/gituser/.ssh

• copy public rsa key from local computer to gituser account on server

scp ~/.ssh/id_rsa.pub [email protected]:/volume1/homes/gituser/.ssh

• connect via SSH as root and rename id_rsa.pub to authorized_keys on NAS (or append if already exists, cat id_rsa.pub >> authorized_keys)

ssh [email protected]
mv /volume1/homes/gituser/.ssh/id_rsa.pub /volume1/homes/gituser/.ssh/authorized_keys

• change permissions while logged in as root

cd /volume1/homes/gituser/
chown -R gituser:users .ssh
chmod 700 .ssh
chmod 644 .ssh/authorized_keys

Set Up New Repo on NAS

• create bare repo as root

ssh [email protected]
cd /volume1/git/
git --bare init <repo-name>.git
chown -R gituser:users <repo-name>.git
cd <repo-name>.git
git update-server-info

NOTE: I'm not entirely sure if git update-server-info must be run for each repo or just initially. It seems to work without running this command, but I'm suspcicious that it might cause problems later.

Add NAS as Remote for Local Repo

• Clone repo from NAS

git clone ssh://[email protected]/volume1/git/<repo-name>.git

Thanks for this precious piece of information.

Just a couple of comments, maybe other people may found these helpful:

1. in my case, on a DS214+, home directories are under /var/services/homes
2. for SCP to work, I had to add the legacy compatibility flag -O otherwise i was getting the error subsystem request failed on channel 0

Even if your guide does not mention SSHing with gituser, I want to point out that after installing the git service, every user - except root - won't connect anymore on SSH giving the error fatal: git package does not support interactive shell.
To fix this, you will need to edit /etc/passwd and restore /bin/sh as the login shell for all affected users.

In addition to this, if you create bare repository directly SSHing with gituser, you won't need to change permissions or ownership of the repo directories.
