Deploying Rocket.Chat on Aliyun

You can install Rocket.Chat to Ubuntu VPS on Aliyun.

The recommended VPS configuration is:

• 2 GB RAM
• 10 GB disk
• 2 or 4 cores

However, lower performance configuration has been tested on a VPS with:

• 1 GB RAM
• 10 GB disk
• 1 core

Follow these steps to install Rocket.Chat.

Update Ubuntu repo lists and Install curl

After you ssh to the VPS:

Run the command:

apt-get update

followed by:

apt-get install curl

Install docker

Run this command:

curl -sSL https://get.docker.com/ | sh

Docker should be installed, verify it:

docker ps

Install docker-compose

Install docker-compose, follow the latest release instructions

For release 1.5.0, you can use:

curl -L https://github.com/docker/compose/releases/download/1.5.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose

(if or when this is blocked, you’ll have to obtain Linux-x86_64 docker-compose binary via other means)

Next, allow execution of docker-compose:

chmod +x /usr/local/bin/docker-compose

Create directories for Rocket.Chat

First,

mkdir /home/rocketchat

Then,

cd /home/rocketchat

Make two more directories for the mongodb database:

mkdir data
mkdir dump

Create customized docker-compose.yml

Create a docker-compose.yml file with the following content:

db:
  image: mongo
  volumes:
    - $PWD/data:/data/db
    - $PWD/dump:/dump
  command: mongod --smallfiles
web:
  image: rocketchat/rocket.chat
  environment:
    - MONGO_URL=mongodb://db:27017/rocketchat
    - ROOT_URL=http://your-ip-address:8818
  links:
    - db:db
  ports:
    - 8818:3000

Make sure you customize the file with your-ip-address in the MONGO_URL env variable.

Pull the required docker images

This will download the required docker images, and may take some time.

This is done only the first time, or when you want to update Rocket.Chat.

docker pull mongo
docker pull rocketchat/rocket.chat

Start the mongodb database

Run:

docker-compose up -d db

Mongo supports 24 x 7 operations and live backup. You should not need to restart it too frequently. See mongodb documentations for proper operation and management of a mongo server.

Wait a couple of minute for mongo to start properly.

Start your Rocket.Chat server

Now start the Rocket.Chat server:

docker-compose up -d web

Rocket.Chat should be ready in a minute or two.

Access your Rocket.Chat on Aliyun

Your Rocket.Chat server can now be accessed over the Internet via:

http://your-ip-address:8818/
