RSYNC

HowTo.md

• Make it exeicutable like: chmod u+x rsync.sh later you have to make chmod u+x .rsyncconfig and chmod u+x .rsyncignore
• ./rsync.sh init
• Do you have password less alias host? (Y/n): means if you use passwordless login like: ssh example.com were example.com is your alias hostname on ~/.ssh/config file.
• ~/.ssh/config file example:

Host example.com
    HostName 12.12.12.12 # Your VPS IP Address
    User root
    Port 22
    IdentityFile ~/.ssh/id_rsa # Your generated SSH key which listed on your VPS authorized_keys
    IdentitiesOnly yes

• SSH Directory Path like: /var/www without backslash (/)

• If you use want to generate ssh key for your VPS create follow this link: https://blog.g3rt.nl/upgrade-your-ssh-keys.html

• There willbe a .rsyncignore file to ignore some files. Open it and make change as your need.

• Please make sure that you added rsync.sh, .rsyncconfig and .rsyncignore file on your .gitignore file

• use ./rsync.sh test-push to check which file is going to upload.

• use ./rsync.sh push to upload file

• use ./rsync.sh test-pull to check which file is going to download from server.

• use ./rsync.sh pull to download from server.
