I wrote a cloud-init script to automate the deployment of a shadowsocks server. I shared it in a gist here.

Features:

• Creates a non-privileged user
  • Uploads your ssh public key to the user
  • Adds this user to the sudoers group
• Disables ssh login for the root user
• Downloads and installs libraries required for chacha20
• Creates a “random” password and writes it in the config.json file
• config.json file is in the /root directory. (You will need the password in this config file to be able to connect to your shadowsocks server.)
• Starts the shadowsocks server.

You have to fill out the _YOURUSERNAMEHERE_, _YOURSSHPUBLICKEYHERE_ and _YOURFULLNAMEHERE_ with your data.

You can use this script in DigitalOcean easily following this document.
