Node.js is a popular runtime environment for executing JavaScript code on the server side. If you are a software developer looking to host a Node.js application with EJS (Embedded JavaScript) on CentOS 7, this article will guide you through the process. We will also set up a reverse proxy using Apache server to handle incoming requests.
Before we begin, make sure you have a CentOS 7 server up and running. Let's dive into the steps:
Step 1: Install Node.js
To host a Node.js application, we need to install Node.js on our CentOS server. Open your terminal and run the following commands:
sudo yum install epel-release sudo yum install nodejs
Once the installation is complete, you can verify it by running node -v and npm -v commands. This will display the installed version of Node.js and npm (Node Package Manager) respectively.
Step 2: Install Apache Server
We will use Apache server as a reverse proxy to handle incoming requests and forward them to our Node.js application. Install Apache server by running the following command:
sudo yum install httpd
Start the Apache server and enable it to start on boot:
sudo systemctl start httpd sudo systemctl enable httpd
Step 3: Set up Reverse Proxy
Now, we need to configure Apache to act as a reverse proxy. Open the Apache configuration file using your favorite text editor:
sudo vi /etc/httpd/conf/httpd.conf
Add the following lines at the end of the file:
ProxyPass / http://localhost:3000/ ProxyPassReverse / http://localhost:3000/
Save and close the file. Restart Apache server for the changes to take effect:
sudo systemctl restart httpd
Step 4: Install EJS
EJS is a popular templating engine for Node.js. Install it by navigating to your project directory and running:
npm install ejs
You can now start developing your Node.js application with EJS.
Congratulations! You have successfully hosted a Node.js application with EJS on CentOS 7 using Apache server as a reverse proxy. Now you can access your application by visiting your server's IP address or domain name in a web browser.
Remember, this is just the beginning of your Node.js journey. Have fun coding and exploring the vast world of Node.js!
