How to Install Lychee Photo Library on ECS

By Arslan Ud Din Shafiq, Alibaba Cloud Tech Share Author. Tech Share is Alibaba Cloud’s incentive program to encourage the sharing of technical knowledge and best practices within the cloud community.

Lychee is an open source photo management tool that helps you to organize your photos and create albums. Lychee does not compress or reduce the quality of the picture. It allows you to import photos from various sources such as from your computer, Dropbox, servers, or from a URL. You can expand Lychee by adding plugins to support features such as synching with any directory containing photos, watermarking your photos, and uploading photos via SSH.

In this tutorial, we will be installing and setting up Lychee photo management tool on an Alibaba Cloud Elastic Compute Service (ECS) with Ubuntu 16.04 installed.

Prerequisites

  • You must have Alibaba Cloud Elastic Compute Service (ECS) activated and verified your valid payment method. If you are a new user, you can get $300 — $1200 worth in Alibaba Cloud credits for your new account. If you don’t know about how to setup your ECS instance, you can refer to this tutorial or quick-start guide. Your ECS instance must have at least 1GB RAM and 1 Core processor.
  • A domain name registered from Alibaba Cloud. If you have already registered a domain from Alibaba Cloud or any other host, you can update its domain nameserver records.
  • Domain name must be pointed to your Alibaba Cloud ECS’s IP address
  • Access to VNC console in your Alibaba Cloud or SSH client installed in your PC
  • Set up your server’s hostname and create user with root privileges.

Setting Up Your Server

Before proceeding with installation of any kind of package, use the following command to update your Ubuntu system. To execute this command, remember to login from non-root user with sudo privileges.

You will need to install unzip which will be used to unzip the compressed zip folder.

Install PHP

Set Up Firewalls and Ports

If you have activated firewalls, you will have to define a rule in Alibaba Cloud security group for your cloud server to add exception for port 80/tcp and 443/tcp. You can enable these ports while creating ECS instance, but in case if you have forgotten to unblock these ports, you can follow the procedure in this guide: https://www.alibabacloud.com/help/doc-detail/25471.htm
