Como instalar Chatwoot via Docker + Codechat + API Whatsapp

Passo 1  – Instalação Docker

• Remover possíveis versões anteriores

for pkg in docker.io docker-doc docker-compose podman-docker containerd runc; do sudo apt-get remove $pkg; done

• Add Docker’s official GPG key

sudo apt-get update
sudo apt-get install ca-certificates curl gnupg
sudo install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg

• Add the repository to Apt sources

echo \
  "deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/debian \
  "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

• Instalação docker

sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
curl -SL https://github.com/docker/compose/releases/download/v2.20.3/docker-compose-linux-x86_64 -o /usr/local/bin/docker-compose

Passo 2 – Instalação do Chatwoot via Docker Compose

• Download the env file template
• Download the Docker compose template
• Rename .env file

cd /root
mkdir chatwoot
wget -O .env https://raw.githubusercontent.com/chatwoot/chatwoot/develop/.env.example
wget -O docker-compose.yaml https://raw.githubusercontent.com/chatwoot/chatwoot/develop/docker-compose.production.yaml

• Ajustando o .env file
• Atenção para senha do postgres

Main
SECRET_KEY_BASE - criar senha segura
FRONTEND_URL=https://app.sacbr.com.br
DEFAULT_LOCALE=pt_BR

Postgres
    POSTGRES_HOST=postgres
    POSTGRES_USERNAME=postgres
    POSTGRES_PASSWORD=908AS7DF89ASIUAFSDAS89034K
    RAILS_ENV=development
Mail
    MAILER_SENDER_EMAIL=SacBR <app@sacbr.com.br>
    SMTP_DOMAIN=smtp.gmail.com
    SMTP_ADDRESS=smtp.gmail.com
    SMTP_PORT=465
    SMTP_USERNAME=sacbr{at}sacbr.com.br
    SMTP_PASSWORD=Senha123
    SMTP_AUTHENTICATION=plain
    SMTP_ENABLE_STARTTLS_AUTO=true
    SMTP_OPENSSL_VERIFY_MODE=peer
    SMTP_SSL=true

• Ajustando o docker-compose.yml
• Atenção para senha do postgres

version: '3'
services:
  base: &base
    image: chatwoot/chatwoot:latest
    env_file: .env ## Change this file for customized env variables
    volumes:

    env_file: .env
    volumes:
      - ./data/redis:/data
    ports:
      - '127.0.0.1:6379:6379'

• Preparar banco de dados

docker compose run --rm rails bundle exec rails db:chatwoot_prepare

• Levantando o serviço

docker compose up -d

• Instalando Nginx e Configurando Proxy Reverso

sudo apt-get install nginx
cd /etc/nginx/sites-enabled
vim yourdomain.com.conf

• Configurando Virtual Host
• Em server name: chatwoot.minhaempresa.com.br

server {
  server_name <yourdomain.com>;

  # Point upstream to Chatwoot App Server
  set $upstream 127.0.0.1:3000;

  # Nginx strips out underscore in headers by default
  # Chatwoot relies on underscore in headers for API
  # Make sure that the config is set to on.
  underscores_in_headers on;
  location /.well-known {
    alias /var/www/ssl-proof/chatwoot/.well-known;
  }

  location / {
    proxy_pass_header Authorization;
    proxy_pass http://$upstream;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_set_header X-Forwarded-Ssl on; # Optional

    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

    proxy_http_version 1.1;
    proxy_set_header Connection “”;
    proxy_buffering off;

    client_max_body_size 0;
    proxy_read_timeout 36000s;
    proxy_redirect off;
  }
  listen 80;
}

• Checando as configurações

nginx -t
systemctl reload nginx

• Instalando Certbot e gerando certififcado

apt  install certbot
apt install python3-certbot-nginx
mkdir -p /var/www/ssl-proof/chatwoot/.well-known
certbot --webroot -w /var/www/ssl-proof/chatwoot/ -d yourdomain.com -i nginx

• Ao chegar nessa etapa do processo de instalação do Chatwoot deverá estar rodando na porta 3000.
• O nginx deverá estar rodando nas portas 80 e 443.
• Proxy reverso deverá estar funcional e buscando chatwoot no localhost.
• Crie sua conta.
• Faça Login para seguir adiante.

Passo 3 – Instalando NodeJS versão 16 (Obrigatório)

–> Adicionar repositório

sudo apt-get update
sudo apt-get install -y ca-certificates curl gnupg
sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://deb.nodesource.com/gpgkey/nodesource-repo.gpg.key | sudo gpg --dearmor -o /etc/apt/keyrings/nodesource.gpg

–> Instalar versão 16

NODE_MAJOR=16
echo "deb [signed-by=/etc/apt/keyrings/nodesource.gpg] https://deb.nodesource.com/node_$NODE_MAJOR.x nodistro main" | sudo tee /etc/apt/sources.list.d/nodesource.list

Passo 4 – Instalar Codechat

git clone https://github.com/w3nder/chatwoot-codechat.git
mv chatwoot-codechat/ codechat
cd codechat
mv .env.example .env

–> Pegar token do usuário dentro do Chatwoot e atualizar
–> Gerar uma chave particular e colocar no CODECHAT_API_KEY Ex: ” 301803677cd97069a55a79038fb0a2ebd4be1e49 ”
–> Se desejar assinar as mensagens como o nome de usuário mude para TOSIGN=true
–> Se desejar receber mensagens enviadas fora do chatwoot mude para IMPORT_MESSAGES_SENT=false

####################################  EXEMPLO ############################
        PORT = 1234
        CHATWOOT_TOKEN = wV7yJG7q28h3RdQY7m4sDzVM
        CHATWOOT_BASE_URL = http://localhost:3000
        CODECHAT_BASE_URL = http://localhost:8080
        CODECHAT_API_KEY = 301803677cd97069a55a79038fb0a2ebd4be1e49
        TOSIGN=true
        IMPORT_MESSAGES_SENT=true
####################################  EXEMPLO ############################

Explicando em sequência:

• Instalar dependências
• Construir aplicação (bildar)
• Rodar aplicação, o prompt ficará preso, assim poderá acompanhar os logs.

npm install
npm run build 
npm start

Passo 5 – Instalar API

• Baixando API
• Renomeando dev-env.yml para env.yml

cd
git clone https://github.com/code-chat-br/whatsapp-api.git
cd whatsapp-api
mv src/dev-env.yml src/env.yml

• Ajustar Server Port
• Ajustar Server URL
• Habilitar Webhook
• Ajustar Client
• Usar chave de acesso configurada no Codechat

vim src/env.yml

Server Port 8080 http
Webhook --> URL: Colocar o link da url webhook: http://0.0.0.0:1234/webhook/codechat
Webhook Enabled: True

Client: Sac BR
--> Autehtication ( PEGAR A CHAVE DO CODECHAT EM cat /root/codechat/.env )

• Explicando em sequência:

  • Instalar dependências
  • Construir aplicação (bildar)
  • Rodar aplicação, o prompt ficará preso, assim poderá acompanhar os logs.

npm install
npm run build
npm run start

Passo 6 – Instalar PM2

• Instalar PM2
• Configurar Codechat como Serviço
• Configurar API como Serviço

npm install pm2 -g

cd /root/codechat
pm2 start dist/app.js --name codechat

cd /root/whatsapp-api
pm2 start 'npm run start prod' --name whatsapp-api

URL: http://192.168.0.254:1234/webhook/chatwoot

PS. Usar endereço IP do Host. Não Usar Localhost - Não Usar 127.0.0.1

apt install postgresql-client postgresql-client-common

psql -U postgres -h localhost -w
\c chatwoot_production
update installation_configs set locked = false;
