Deploying pimentaCHAT on Aliyun

You can install pimentaCHAT 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 pimentaCHAT.

Update Ubuntu repo lists and Install curl

After you ssh to the VPS:

aliyun shell

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

aliyun docker verify

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 pimentaCHAT


mkdir /home/pimentachat


cd /home/pimentachat

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:

  image: mongo
    - $PWD/data:/data/db
    - $PWD/dump:/dump
  command: mongod --smallfiles
  image: pimentachat/pimenta.chat
    - MONGO_URL=mongodb://db:27017/pimentachat
    - ROOT_URL=http://your-ip-address:8818
    - db:db
    - 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 pimentaCHAT.

docker pull mongo
docker pull pimentachat/pimenta.chat

Start the mongodb database


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 pimentaCHAT server

Now start the pimentaCHAT server:

docker-compose up -d web

pimentaCHAT should be ready in a minute or two.

Access your pimentaCHAT on Aliyun

Your pimentaCHAT server can now be accessed over the Internet via:
