How to Run NodeJS on Liquid Web?

9 minutes read

To run NodeJS on Liquid Web, follow these steps:

  1. Connect to your server via SSH or use the server's built-in command line interface.
  2. Ensure that NodeJS is installed on your server. You can check if NodeJS is installed by running the command node -v. If it's not installed, you can install it using a package manager like yum or apt.
  3. Create a new directory for your NodeJS application. You can do this by running the command mkdir myapp (replace "myapp" with the desired name for your application).
  4. Navigate to the newly created directory using the command cd myapp.
  5. Now you can create a new NodeJS application file. You can use a text editor like nano or vi to create a file named app.js or any other name you prefer.
  6. Write your NodeJS application code in the new file. For a simple "Hello World" application, you can use the following code:
 1

const http = require('http');
const hostname = '127.0.0.1';
const port = 3000;

const server = http.createServer((req, res) => {
  res.statusCode = 200;
  res.setHeader('Content-Type', 'text/plain');
  res.end('Hello, World!\n');
});

server.listen(port, hostname, () => {
  console.log(`Server running at http://${hostname}:${port}/`);
});


  1. Save the file once you are done editing.
  2. Start your NodeJS application by running the command node app.js (replace "app.js" with the name of your application file).
  3. Your NodeJS application should now be running. You can access it through a web browser by entering the server's IP address or domain name followed by the port number specified in your application code (e.g., http://yourdomain.com:3000).


That's it! You have successfully set up and run a NodeJS application on Liquid Web.

How to check if NodeJS is already installed on Liquid Web?

To check if Node.js is already installed on your Liquid Web server, you can follow these steps:

  1. Access your server via SSH by using your preferred SSH client or the built-in web-based SSH client in your Liquid Web account.
  2. Once connected to your server, run the following command to check if Node.js is installed:
1
node -v


  1. If Node.js is installed, it will display the version number. For example, the output may look like this:
1
v12.22.1


  1. If Node.js is not installed, you can either install it or contact Liquid Web support for assistance.


Note: This method checks if Node.js is installed globally on your server. It is possible that Node.js may be installed locally within a specific user's directory, in which case you would need to log in as that user and run the node -v command within their account.


What is the process to set up NodeJS on Liquid Web?

To set up Node.js on Liquid Web, follow these steps:

  1. Log in to your Liquid Web account and navigate to the Manage tab.
  2. In the sidebar, click on the "Servers" option and select the server on which you want to install Node.js.
  3. Click on the "Access" button for the chosen server to open the additional options.
  4. From the dropdown menu, select "Web Connection Info" to get your server's IP address and SSH port information.
  5. Use an SSH client (such as PuTTY for Windows or Terminal for macOS) to connect to your server using the IP address and SSH port.
  6. Once connected, you can install Node.js using the package manager associated with your server's operating system: On CentOS/RHEL: Run the command sudo yum install nodejs to install Node.js. On Ubuntu/Debian: Run the command sudo apt-get install nodejs to install Node.js.
  7. Verify the successful installation by checking the node.js version: node -v.
  8. Additionally, you can also install the Node Package Manager (npm) by running the appropriate command for your operating system: On CentOS/RHEL: sudo yum install npm On Ubuntu/Debian: sudo apt-get install npm
  9. Confirm npm installation by checking the version: npm -v.
  10. Now you can start developing and deploying Node.js applications on your Liquid Web server.


Remember to configure any necessary security measures and other server settings according to your requirements.


What are the steps to deploy a NodeJS app to Liquid Web?

To deploy a Node.js app to Liquid Web, you can follow these steps:

  1. Connect to your Liquid Web server: Use an SSH client (like PuTTY or Terminal) to connect to your server using the provided IP address, username, and password.
  2. Install Node.js: Check if Node.js is already installed by running node -v in the terminal. If not, you can install Node.js using the following commands, depending on your server's operating system: CentOS: sudo yum install nodejs Ubuntu/Debian: sudo apt-get install nodejs
  3. Prepare your Node.js app: Create a directory on your server to store your Node.js app. Upload your app's files to the server using SCP (secure copy) or file transfer protocols like SFTP or FTP. You can use an FTP client like FileZilla for this task.
  4. Configure your Node.js app: Navigate to your app's directory on the server using the terminal (cd /path/to/your/app). Install the app's dependencies by running npm install in the app's directory. This will read the 'package.json' file and install all required packages.
  5. Start your Node.js app: Run your Node.js app in the background using a process manager like PM2, which helps ensure your app continuously runs even after server restarts. Install PM2 globally by running npm install -g pm2. Start your app by running pm2 start app.js (replace app.js with the entry point file of your app). Verify that your app is running by entering pm2 list to display running processes.
  6. Configure a reverse proxy: To make your app accessible over the web, you need to configure a reverse proxy in your server's web server (like Apache or Nginx). For Apache, you can create a virtual host file (e.g., yourapp.conf) in the /etc/httpd/conf.d/ directory and configure it to forward requests to your Node.js app. For Nginx, create a server block in /etc/nginx/conf.d/ or /etc/nginx/sites-available/ directory. Configure it to proxy requests to your Node.js app using the proxy_pass directive. After configuring, restart your web server (service apache2 restart or service nginx restart).
  7. DNS configuration (optional): If you want to associate a domain name with your Node.js app, you'll need to update your DNS settings with your domain registrar or DNS provider. Create an 'A' record pointing to your server's IP address or update the existing 'A' record to your server's IP.


Now, you should be able to access your Node.js app by entering your server's IP address or domain name in a web browser.


What is the command to check the current NodeJS version on Liquid Web?

What is the command to install a specific version of NodeJS on Liquid Web?

To install a specific version of Node.js on Liquid Web, you need to use the n package manager. Here are the steps:

  1. Connect to your Liquid Web server via SSH.
  2. Confirm that you have npm installed. If not, you can install it by running: curl -L https://npmjs.org/install.sh | sh
  3. Install the n package manager globally using npm: npm install -g n
  4. Now, use the n package manager to install the specific Node.js version you want. For example, to install Node.js version 14.x.x, run: n 14 This will install the latest 14.x.x version available. Alternatively, if you want to install a specific minor version, you can run: n 14.17.6 Replace 14.17.6 with the desired version number.
  5. After the installation completes, you can verify the installed version by running: node -v


Note that these instructions assume a Linux-based Liquid Web server. If you have a different server type (e.g., Windows), the steps might be slightly different.
