NVM
Prerequisites
Before starting the installation of Evolution API v2, ensure that you have already configured the necessary services, such as PostgreSQL and Redis. Follow the links below for more details:
NVM Installation
Evolution API can be easily installed using Node Version Manager (NVM). Follow these steps to set up your environment and start the Evolution API on your server.
Install NVM
First, download and install Node.js with the following commands:
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash
Now, load the environment and install Node.js:
# Load NVM into the current environment
source ~/.bashrc
# Install and use the required Node.js version
nvm install v20.10.0 && nvm use v20.10.0
Confirm that NVM was successfully installed:
command -v nvm
If you haven’t set it up yet, you can also configure your server’s timezone with the command:
dpkg-reconfigure tzdata
Cloning the Repository and Installing Dependencies
Clone the official Evolution API v2 repository from the correct branch:
git clone -b v2.0.0 https://github.com/EvolutionAPI/evolution-api.git
Navigate to the project directory and install the dependencies:
cd evolution-api
npm install
Environment Variables Configuration
Now let’s configure the environment variables. First, copy the .env.example
file to .env
:
cp ./.env.example ./.env
Edit the .env
file with your specific settings:
nano ./.env
Replace the default values with your configurations, such as database connection strings, API keys, server ports, etc.
Visit the environment variables section for detailed instructions on how to configure your .env
file.
Database Generation and Deployment
After setting up the environment, you will need to generate the Prisma client files and deploy the migrations to the database. Use the following commands, depending on the database you are using (PostgreSQL or MySQL):
-
Generate the Prisma client files:
npm run db:generate
-
Deploy the migrations:
npm run db:deploy
Starting the Evolution API
After configuration, you can start the Evolution API with the following command:
npm run build
npm run start:prod
PM2 Installation and Configuration
Use PM2 to manage the API process:
npm install pm2 -g
pm2 start 'npm run start:prod' --name ApiEvolution
pm2 startup
pm2 save --force
If your server has more memory, consider configuring PM2 to utilize more resources:
pm2 start 'npm run start:prod' --name ApiEvolution -- start --node-args="--max-old-space-size=4096" --max-memory-restart 4G
This is recommended for servers with at least 4GB of RAM exclusively available for the Evolution API.
To verify that the API is running, visit http://localhost:8080. You should see the following response:
{
"status": 200,
"message": "Welcome to the Evolution API, it is working!",
"version": "2.0.10",
"clientName": "evolution01",
"manager": "https://evo2.site.com/manager",
"documentation": "https://doc.evolution-api.com"
}
