stransfer.sh is a script to facilitate routine operations of websites' transfer from the one server to another. It's a really quick and easy way to copy your database and files.

Used utilities

This utilities are necessary for stransfer.sh:

• sshpass
• OpenSSH client/server
• scp or rsync
• mysql

Options

stransfer.sh reads its settings from a configuration file. This file is named .stransfer.conf by default and located in the same directory with the main script. You can change the location of the file using a key -f:

sh stransfer.sh -f path/to/your/config/.stransfer.conf

The configuration file is included by source command so you need to set the options as bash variables

List of variables:

• TRANSFER_METHOD - the method of files transfering, rsync (by default) or scp

• REMOTE_SSH_CONNECTION - the ssh connection string in a format <user>@<host>

• AUTH_TYPE - a type of ssh authentification. Allowed values: stransferPubkey or sshpass.

  ssh with different AUTH_TYPE:

  AUTH_TYPE=sshpass: sshpass -p "${REMOTE_SSH_PASSWORD}" ssh -p "${SSH_PORT}" -o BatchMode=yes -o ConnectTimeout=5 "${REMOTE_SSH_CONNECTION}"

  AUTH_TYPE=stransferPubkey: ssh -p "${SSH_PORT}" -i "~/.ssh/stransfer" -o BatchMode=yes -o ConnectTimeout=5 "${REMOTE_SSH_CONNECTION}"

  AUTH_TYPE isn't set: ssh -p "${SSH_PORT}" -o BatchMode=yes -o ConnectTimeout=5 "${REMOTE_SSH_CONNECTION}"

  If the public key authentification is necessary, check the option PubkeyAuthentication isn't set to no in the sshd configuration

• REMOTE_SSH_PASSWORD - the password for ssh conection. It's used when AUTH_TYPE is set to sshpass

• SSH_PORT - the port of the ssh connection, it's set to 22 by default

• LOCAL_PATH - the files' transfering aim directory on the local server

• REMOTE_PATH - the files' transfering source directory on the remote server

• CLEAR_LOCAL_DIR - if it set to true (by default), a local directory is cleared before files transfer

• LOCAL_DB_NAME - a database name on the current server

• LOCAL_DB_USER - a user with permissions to the local database

• LOCAL_DB_PASSWORD - the local database user password

• REMOTE_DB_NAME - a database name on the remote server

• REMOTE_DB_USER - a user with permissions to the remote database

• REMOTE_DB_PASSWORD - the remote database user password

• LOCAL_DUMP_PATH - a temporary local directory for database dump

• REMOTE_DUMP_PATH - a temporary remote directory for database dump

Usage

When the script is running, select the operation in the main menu:

1. Create a rsa public key and add it to the remote server
   It tries to create and add ssh public key to remote server using ssh-keygen and ssh-copy-id. Created key is named stransfer and has not got a password. This key will be used when you set the option AUTH_TYPE to stransferPubkey.
2. Copy files from the remote server (rsync or scp)
   Copy files from REMOTE_PATH to LOCAL_PATH using TRANSFER_METHOD.
3. Copy database from the remote server
   Create a database dump in the remote server then copy and import it to local database. Now only mysql is supported so it uses mysqldump to a dump creation. Options LOCAL_DUMP_PATH and REMOTE_DUMP_PATH set directories to dump storage, both directories will be removed after the operation's finish.
4. Exit
   Quit the script

Also you can run every step using the key -s:

sh stransfer.sh -s addStransferPubKey -s copyFiles -s copyDatabase

Known problems and solutions

When you create copy rsa public key (the operation #1 on the main menu) you can see the error message:

/usr/bin/ssh-copy-id: ERROR: No identities found

or:

Bad port 'exec sh -c 'cd; umask 077; test -d .ssh || mkdir .ssh ; cat >> .ssh/authorized_keys && (test -x /sbin/restorecon && /sbin/restorecon .ssh .ssh/authorized_keys >/dev/null 2>&1 || true)''

The reason may be that you use the old openssh version and the syntax of ssh-copy-id was changed. Try to set the variable OLD_SSH_VERSION to true and repeat the operation.
In contrast, if you see a message:

Usage: /usr/bin/ssh-copy-id [-h|-?|-f|-n] [-i [identity_file]] [-p port] [[-o <ssh -o options>] ...] [user@]hostname -f: force mode -- copy keys without trying to check if they are already installed -n: dry run -- no keys are actually copied -h|-?: print this help

it means you have a modern version of ssh, but the variable OLD_SSH_VERSION is set to true.
