Strapi is a popular open-source headless CMS (Content Management System) built with Node.js. It provides a customizable and extensible platform for building APIs and managing content.
At times, you might need to restart Strapi server to apply changes, fix issues, or update configurations. This guide will walk you through the process step-by-step.
Prerequisites
Before we begin, ensure you have the following:
Strapi is an open-source Headless CMS (Content Management System) built on Node.js. In simpler terms, it’s a backend application that allows you to manage and create content for your website or app. Since it’s headless, Strapi doesn’t dictate how your content is displayed on the front end. This gives you flexibility in how you design and develop the user interface of your website or app.
The Strapi server is the core component of a Strapi application. It handles things like data storage, user permissions, and communication with the front end. You can customize the server to fit the specific needs of your project through plugins. These plugins add features and functionalities to your Strapi application.
Strapi offers a free community edition and a paid enterprise edition. The free edition is a good option for personal projects or small businesses. The enterprise edition provides additional features such as improved scalability and security.
Here’s a breakdown of what that means:
So, essentially, the Strapi server is the engine that powers your Strapi application. It’s responsible for managing content, handling user interactions, and delivering content through APIs.
Strapi is an open-source headless content management system (CMS) that simplifies and expedites the construction of APIs and content. Understanding how to restart your Strapi server is essential, regardless of whether you’re creating a new feature or implementing important improvements.
You can easily restart your Strapi server by following these, step-by-step instructions.
First, open your terminal or command prompt. Navigate to the root directory of your Strapi project. This is the folder where your project was initialized and contains files like package. Json.
Replace path/to/your/strapi-project with the actual path to your Strapi project directory.
If your Strapi server is currently running, you need to stop it before restarting. You can do this by pressing Ctrl + C in the terminal where the server is running. This will terminate the process.
Alternatively, if you have started Strapi in the background or through a process manager, you will need to stop it using the appropriate command. For example, if you are using PM2 (a process manager for Node.js applications), you can stop the server using
pm2 stop strapiIn some cases, clearing the cache can help resolve issues. You can do this by deleting the. cache and build directories in your Strapi project.
rm -rf. cache buildThis step is optional but recommended if you are facing persistent issues or have made significant changes to your project.
Now that you have stopped the server and optionally cleared the cache, you can restart the Strapi server. The method to restart depends on how you initially started it.
1: Using npm or yarn
If you started Strapi using npm or yarn, you can restart it with the following commands:
For npm:
npm run developFor yarn:
yarn develops2: Using PM2
If you are using PM2, you can restart the server with:
pm2 restart strapi3: Using Docker
If you are running Strapi inside a Docker container, you can restart the container using Docker commands. First, list the running containers to find the container ID or name:
Then, restart the Strapi container using:
Replace container_id_or_name with the actual ID or name of your Strapi container.
After restarting the server, it is essential to verify that it is running correctly. You can do this by checking the terminal output for any errors. The server should start without any issues and display a message indicating that it is running.
Additionally, you can open your web browser and navigate to the Strapi admin panel at http://localhost:1337/admin (or the appropriate URL if you have configured a different port). Log in to the admin panel to ensure everything is working correctly.
An effective option to keep control over your web application infrastructure is to host Strapi, an open-source headless content management system, on a Virtual Private Server (VPS). Your Strapi instance can be deployed and managed more easily with the help of the Strapi VPS Template, which simplifies the setup procedure.
We’ll walk you through each step so you can use the Strapi VPS Template efficiently.
Before diving into the setup, it’s important to understand the VPS environment you’ll be working with. A Virtual Private Server (VPS) provides a dedicated virtualized server environment that offers significantly more control and customization compared to shared hosting. You can check the benefits and advantages of a VPS for better performance and control understanding.
Here, you’ll install and configure Strapi, a Node.js-based CMS, which allows you to create and manage your content effortlessly.
Prerequisites:
Once you have your VPS set up and ready, follow these steps to configure Strapi.
Use an SSH client to connect to your VPS. For example:
Ensure you have Node.js and npm installed. You can install them using the following commands:
curl -sL https://deb.nodesource.com/setup_14.x | bash -
apt-get install -y nodejsWith Node.js and npm installed, you can now install Strapi. Navigate to the directory where you want to set up your project and run:
npx create-strapi-app my-project --quickstartThis command will create a new Strapi project named “my-project” with a SQLite database.
If you prefer to use a different database, such as PostgreSQL, MySQL, or MongoDB, update your config/database.js file with the appropriate database configurations.
Navigate to your project directory and start Strapi:
Strapi will start, and you can access the admin panel at http://your-vps-ip-address:1337/admin.
To keep your Strapi application running smoothly, even after reboots or crashes, it’s recommended to use a process manager like PM2.
Install pm2 globally using npm:
npm install pm2@latest -gNavigate to your Strapi project directory and start your application with pm2:
pm2 start npm --name "strapi" -- run developThis command tells pm2 to run the npm run develop script and names the process “strapi”.
You can manage your Strapi application using various pm2 commands:
View all pm2 processes:
pm2 listRestart the Strapi process:
pm2 restart strapiStop the Strapi process:
pm2 stop strapiEnsure pm2 starts on boot:
pm2 startup
pm2 saveNow that your Strapi backend is up and running, you need to deploy your frontend to interact with it. This could be a React, Vue, Angular application, or any other front-end framework.
Build your frontend application using the framework’s build tools. For example, if you’re using React, you might run:
npm run buildThis command creates an optimized build of your application in the build directory.
Copy your built frontend files to a web server directory on your VPS. You can use a web server like Nginx or Apache to serve your static files. Here’s an example using Nginx:
Install Nginx:
apt-get update
apt-get install nginxConfigure Nginx to serve your front end. Edit the Nginx configuration file, usually located at /etc/nginx/sites-available/default:
server {
listen 80;
server_name your-domain.com;
root /var/www/my-frontend;
index index.html;
location / {
try_files $uri $uri/ /index.html;
}
location /api {
proxy_pass http://localhost:1337;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
}This configuration serves your frontend from /var/www/my-frontend and proxies API requests to your Strapi backend.
Reload Nginx to apply the changes:
systemctl reload nginxNavigate to your domain to ensure your front end is correctly served and communicates with your Strapi backend.
Using the Strapi VPS Template simplifies the process of deploying and managing a Strapi application on a VPS.
By following the steps outlined in this guide, you can set up a robust and scalable environment for your headless CMS, manage it effectively with PM2, and deploy your front end for a seamless user experience.
With this setup, you have full control over your application infrastructure, ensuring optimal performance and flexibility.
Restarting the Strapi server is a straightforward process, whether you are using npm, yarn, PM2, or Docker. Following the steps outlined in this guide will help you restart your server smoothly and ensure that your Strapi application runs without issues. If you encounter any problems, refer to the troubleshooting section for common solutions.
By following these steps, you can effectively manage your Strapi server and keep your project running smoothly.
To restart the Strapi server using the command line, navigate to the root directory of your Strapi project. You can do this by opening your terminal and using the cd command to change directories. Once you are in the root directory of your Strapi project, stop the running server by pressing Ctrl+X.
After stopping the server, you can restart it by running the command npm run develop or yarn develop, depending on the package manager you are using. This command will start the server in development mode, allowing you to see live changes as you make updates to your project.
If your Strapi server is not restarting properly, there are several troubleshooting steps you can take. First, ensure that there are no syntax errors or issues in your code that might be causing the server to crash. You can check the terminal for any error messages that might indicate what the problem is.
If there are no obvious errors, try clearing the cache by deleting the cache and build folders in your Strapi project directory. After deleting these folders, try restarting the server again. If the issue persists, make sure that your dependencies are up-to-date by running npm install or yarn install to reinstall the necessary packages.
Yes, you can automate the restarting of the Strapi server using tools like Nodemon. Nodemon is a utility that monitors changes in your source code and automatically restarts the server when it detects any changes. To use nodemon, first, install it globally on your system by running npm install -g nodemon.
Then, instead of running npm run develop or yarn develop, use nodemon to start your Strapi server by running nodemon –exec “npm run develop” or nodemon –exec “yarn develop”. This setup ensures that your server restarts automatically whenever you make changes to your code, saving you the hassle of manually restarting it each time.
Restarting the Strapi server in a production environment typically involves using a process manager like PM2 or a similar tool. PM2 is a popular process manager for Node.js applications that provides features for monitoring, managing, and restarting your server. To use PM2, first, install it globally by running npm install -g pm2.
Then, start your Strapi server with PM2 by running pm2 start npm –name “strapi” — run start. To restart the server, you can use the command pm2 restart strapi. PM2 also allows you to set up automatic restarts, monitoring, and log management, which are essential for maintaining a stable production environment.
Common issues faced while restarting a Strapi server include port conflicts, corrupted cache, and outdated dependencies. Port conflicts occur when the port that Strapi is trying to use is already in use by another process. To resolve this, ensure that the port is free or change the port number in the server.js configuration file.
The corrupted cache can cause the server to behave unexpectedly. Deleting the cache and build folders and then restarting the server can often resolve this issue. Outdated dependencies might cause compatibility issues. Keeping your dependencies up-to-date by running npm install or yarn install can help prevent these problems.
Additionally, regularly checking for updates to Strapi and its plugins can help maintain a smooth and error-free development experience.
