Setup & Deployment


Local installation

The following documentation will guide you through the installation of an erxes project using Docker.

Docker is an open platform that allows to develop, ship and run applications by using containers (i.e. packages containing all the parts an application needs to function, such as libraries and dependencies).

Preparing the installation

erxes installation requires at least four software prerequisites to be already installed on your machine:

Prerequisites

  • Git
  • Node.js: only LTS versions are supported v18.17.1 or higher. Other versions of Node.js may not be compatible with the latest release of erxes. The 18.17.x version is most recommended by erxes. The easier way to install nvm is here.
  • npm and yarn (latest version) to run the erxes.
  • Docker Latest version.

Installing erxes

  1. Create an empty folder.
mkdir example
  1. Navigate to your newly created folder where the new erxes project will be set up. This directory will define the database and erxes plugins to use.
cd example
  1. Run the following command in the folder.
git clone https://github.com/erxes/erxes.git

Installing dependencies using docker

  1. In the folder, create a dock directory using the following command.
mkdir dock
  1. Go to the dock folder using the following command.
cd dock
  1. Create a docker-compose.yml file, then copy the following script into the newly created file.

  1. Go back to the erxes folder using the following command.
cd ../erxes
  1. Switch to the dev branch by using the following command.
git checkout dev
  1. In erxes folder, Install node modules by using the following command.
yarn install
  1. Install pm2 by using the following command.
sudo npm install -g pm2

Running erxes

  1. Run the following command to change the folder.
cd cli
  1. Install node modules in the erxes/cli directory.
yarn install
  1. Copy configs.json.sample, then convert it to configs.json.
cp configs.json.sample configs.json
  1. Add "ui": "local" under every plugin names like shown in below, in configs.json.
 {
    "name": "inbox",
    "ui": "local"
 },
  1. Run the following command to start your erxes project.
./bin/erxes.js dev

If your browser doesn't automatically jump to localhost:3000, you should check logs by using these commands.

If you see this screen, you have successfully installed erxes XOS. Congratulations πŸŽ‰πŸŽ‰πŸŽ‰


Server installation

The following documentation will guide you through the installation of an erxes project using Docker image via Dockerhub that can be used on Ubuntu/CentOS in order to use erxes. This the guideline will be dedicated to anyone who is about to use erxes for their businesses. If you want to customize or develop additional plugins on erxes, please go to the developer installation guideline.

Docker is an open source platform that allows to develop, ship and run applications by using containers (i.e. packages containing all the parts an application needs to function, such as libraries and dependencies).

Prerequisites

You will need following things before dive into erxes installation.

  • any type of server with 8 core cpu & atleast 16gb ram
  • basic knowledges to work on ubuntu/centos operating system such as execute commands in user directory
  • domain controller's A record must pointed to the instance you are going to install erxes on
  • ability to connect to your instance via ssh protocol

Installation steps

1. Create install.sh file using text editors such as nano or vim. Then copy the following content into install.sh. Following script will install nginx, certbot, docker, docker-compose and nodejs into your server.

 #!/bin/bash
  now=$(date +'%H:%M:%S')
  echo -e "\e[1mStep 1 $now : Updating \e[0m"
sudo apt-get update -y
  now=$(date +'%H:%M:%S')
  echo -e "\e[1mStep 2 $now : Installing nginx\e[0m"
sudo apt install nginx -y
sudo apt update -y
  now=$(date +'%H:%M:%S')
  echo -e "\e[1mStep 3 $now : Installing docker\e[0m"
sudo apt install apt-transport-https ca-certificates curl software-properties-common -y
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu focal stable"
apt-cache policy docker-ce
sudo apt install docker-ce -y
  now=$(date +'%H:%M:%S')
  echo -e "\e[1mStep 5 $now : Installing docker compose\e[0m"
sudo apt-get update -y
sudo curl -L "https://github.com/docker/compose/releases/download/1.27.4/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
  now=$(date +'%H:%M:%S')
  echo -e "\e[1mStep 6 $now : Installing ndoejs\e[0m"
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash
curl -s https://deb.nodesource.com/setup_18.x | sudo bash
sudo apt-get install nodejs -y
  now=$(date +'%H:%M:%S')
  echo -e "\e[1mStep 7 $now : Installing awscli \e[0m"
sudo apt-get install awscli -y
  now=$(date +'%H:%M:%S')
  echo -e "\e[1mStep 8 $now : Installing npm\e[0m"
sudo apt install npm -y
  now=$(date +'%H:%M:%S')
  echo -e "\e[1mStep 9 $now : Enter your domain address to configure erxes\e[0m"
sudo npm install -g create-erxes-app -y

2. Before executing the script use the below command to make the install.sh file executable.

sudo chmod +x install.sh

3. Execute install.sh file.

./install.sh

Create an erxes user on the instance

Assuming you have connected to your instance and ready to execute following steps. First you need to create erxes user because all erxes related installation scripts are made for an erxes user. Why? You don't want to use root user to administer your server. So everything will be done by a user called, erxes. To accomplish this, run the following command:

adduser erxes

When prompted, enter unique & strong password. (Finish adding the user simply by pressing the enter or return key through the questions)

Grant sudo and docker rights to erxes user by following command::

usermod -aG sudo erxes
usermod -aG docker erxes
su - erxes

All prerequisites are completed and now you can proceed to the installation steps.

Starting erxes project

1. Below command will trigger the erxes installation process.

create-erxes-app erxes

After the execution it will ask for your erxes domain name

https://example.com

2. After the above command erxes directory will be created. That includes following files in it docker-compose.yml, configs.json, package.json, package-lock.json. In order to change to erxes directory use below command.

cd /home/erxes/erxes

3. Change erxes package version of /home/erxes/erxes/package.json file to latest version.

{
  "name": "erxes",
  "private": true,
  "version": "0.1.0",
  "scripts": {
    "erxes": "erxes"
  },
  "dependencies": {
    "amqplib": "^0.8.0",
    "create-erxes-app": "0.0.28",
    "dup": "^1.0.0",
    #Change here
    "erxes": "change me",
    "ip": "^1.1.5",
    "up": "^1.0.2"
  }
}

If the erxes version has been changed in the package.json file, run the command below to install the necessary modules for erxes.

npm install

4. Now you need to initiate docker swarm mode in order to do that use following command.

docker swarm init
docker network create --driver=overlay --attachable erxes

5. Before starting the application services we need to start the databases. The following command will start database services.

openssl rand -base64 756 > mongo-key
sudo chmod 400 mongo-key && sudo chown 999:999 mongo-key
openssl req -newkey rsa:2048 -nodes -keyout key.pem -x509 -days 365 -out certificate.pem --batch
cat key.pem certificate.pem > mongo.pem

Running elasticsearch

If your server is bigger than our required size you can use erxes with elasticsearch. To do that the following steps need to be taken.

Add the following lines to configs.json, positions do not matter.

"essyncer": {},
"elasticsearch" : {},

Then run and deploy dbs with following command.

npm run erxes deploy-dbs

6. To check database services up use following command it will shows you all the running docker services id, name and state etc.

docker ps -a | grep mongo

wait until all services' state become up.

7. Now we need to make our mongo have a replica set. First we need to enter the mongo container then enter the mongo instance then execute the 3 following commands.

docker exec -it <mongo container name> bash
mongo -u erxes -p <auto generated in configs.json>
rs.initiate();

To quit mongo instance and container run exit command twice.

8. Now we need to create locales directory in our working directory /home/erxes/erxes to do that use the following command.

mkdir locales

9. Change erxes version of /home/erxes/erxes/configs.json file to latest version. It is the latest version that has undergone further development.

To start the application services like erxes core uis and gateway services we need to run the following command.

npm run erxes up -- --uis

After this step the ui will be downloaded from AWS:s3 so make sure your server can communicate AWS instances without a problem.

10. Now we need to configure our web server, we need to configure our nginx first. To do this, we create an nginx config file named erxes.conf in /etc/nginx/sites-enabled. To do this, use the following command.

sudo nano /etc/nginx/sites-enabled/erxes.conf

Copy the nginx configuration below

server {
        server_name example.com;
        index index.html;
        client_max_body_size 50M;
        client_header_buffer_size 32k;

                proxy_set_header X-Forwarded-Proto $scheme;
        }
    }

11. After that we need to test the nginx config. To do that use following command.

sudo nginx -t

12. If nginx test shows successful message we need to restart Nginx. To do that use the following command.

sudo service nginx restart

13. Erxes only works in secure connection to generate free ssl certificate we use Certbot. To configure that use the following command.

sudo certbot --nginx

After entering this command, provide your email and subscription information, and accept the terms. Following that, you will be prompted about the 'redirect' option. We highly recommend enabling this option for security reasons. Once these steps are completed, open your browser and enjoy our product.

Adding new plugins to erxes

Adding new plugins to erxes is an easy task, all you need to do is add a plugin name under "plugins:"[{}] in /home/erxes/erxes/configs.json file then run npm run erxes up -- --uis command. But for some plugins like dashboard, it require some extra service we will discuss that in another section. Below we have the ideal configs.json file content that includes every nessacery configuration lines for all plugins. Please read the following contents carefully some lines may need a replacement.

Removing erxes

1. First, it is unfortunate, but every server needs to be kept tidy. The following commands will help remove the Docker stack and any dangling containers in the swarm.

docker stack ls

will show you stack informations. To leave that use the following command.

docker stack rm erxes
docker stack rm erxes-dbs

2. To remove all dangling containers use the following commands.

List and remove all dangling images.

docker images -f dangling=true
docker rmi $(docker images -q -f dangling=true)

List and remove all dangling containers.

docker ps -a -f status=exited
docker rm $(docker ps -a -q -f status=exited)

List and remove all dangling volumes

docker volume ls -f dangling=true
docker volume rm $(docker volume ls -q -f dangling=true)
