basic deployment script using rsync

Here is a simple rsync script that you can use to deploy/provision/baseline any webapp with


#!/usr/bin/env sh

user_name=devuser
export user_name

private_key=config/id_dsa
export private_key

remote_host=192.168.3.111
export remote_host

local_path=./
export local_path

remote_path=/var/www/vhosts/usmagazine
export remote_path

exclude_file=config/rsync_exclude.txt
export exclude_file

# -e in the rsync command forces rysnc to use ssh as the transport protocol and then
# it passes -ax to the ssh command to disable interactive shell and x11 on the server

# -C in the rsync command causes rsync to ignore the subversion and cvs folders in the
# directory tree

# -a in the rysnc command puts rsync in archive mode recursing all folders and
# preserving users symlinks permissions and timestamps

# -z turns on rsync compression

# --delete will delete any files from the remote file system that don't exist on the
# local file system

# --force forcibly answers yes to any prompts for confirmation from rsync

# --exclude-from passes in a file that contains patterns (1 per line) that match files
# using rsync's pattern matching syntax (* for wildcard etc.) a line preceded with a +
# tells rsync to include any files matching the pattern and a line preceded by - tells
# rsync to ignore files matching the pattern. By default all files are included so
# most times you only have to make patterns to black list certain files (for instance
# configuration files that are specific to your sandbox and that should not be
# transferred to a production server)

rsync --progress -azC --force --delete --exclude-from=$exclude_file -e "ssh -ax -i $private_key" $local_path $user_name
