Deployment by SSH

When deploying to a remote server from SyncRelease, depolyment by SSH is the most efficient way because it only transfers only the modified/updated files and changes, whereas FTP is slow and will transfer all of the codes for a new complete overwrite.

Deployment by SSH works nicely when SyncRelease is running on Linux and remote destination is also a Linux server. Currently, it supports for deployment scenarios such as:

  • Linux to Linux
  • Linux to Windows (by installing Cygwin on remote Windows server)


Here Linux means it also includes Mac OS since it is based on a linux kernel.

How to setup for Deployment by SSH (Linux to Linux)

  1. First login to linux server where SyncRelease is running via SSH terminal. If you are accessing from Windows machine, you can use Putty program.

  1. Then, generate ssh key pair for web server user by running the following command, assuming www-data is username for Apache or webserver
sudo -u www-data ssh-keygen -t rsa


After that, you should see two (private/public) rsa files newly created: id_rsa and By default, those files will be created in web server user’s home directory or the path you entered in key generation.

  1. Login to remote server where you want to deploy, in another SSH terminal window and go to the user’s home directory such as /root or /home/user

  1. Create .ssh directory if it does not exist, run the following command:
mkdir -p .ssh
  1. Then in SSH terminal console for SyncRelease server, issue the command like below by replacing user@remote with actual username and remote server host you used to log in step 3.
cat /var/www/.ssh/ | ssh user@remote 'cat >> .ssh/authorized_keys'


In this case, we are assuming the directory where RSA key files are generated is /var/www. You may replace it with actual directory path you used in step 2 for generating RSA key files.

If you are using SSH2 to login to remote server, you will need to change the command to use authorized_keys2 instead of authorized_keys.

  1. Login to SyncRelease and add an environment for the site you want to deploy using SSH mode, as shown below.



  • Destination path on remote server you entered for your site must be write-able by the user you used in Step 5.
