Teach you how to deploy NGINX and PM2 on a VPS server
Foreword:
The deployment of a VPS server is one of the key steps for a website or application. Here, I will introduce to you how to deploy NGINX and PM2 on a VPS server. These two tools can greatly improve the performance and stability of the website. This article will introduce the installation and configuration process in detail and provide specific code examples.
- Installing NGINX:
First, we need to install NGINX as our web server.
1.1 Update apt-get package management tool:
sudo apt-get update
1.2 Install NGINX:
sudo apt-get install nginx
Configuration file location: /etc/nginx/nginx.conf
.
- Configure NGINX:
2.1 Create a new site configuration file:
sudo nano /etc/nginx/sites-available/myapp
2.2 In the file, enter the following:
server { listen 80; server_name your_domain.com; location / { proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host $host; proxy_pass http://localhost:3000; } }
Note: Replace "your_domain.com" with your domain name and "http://localhost:3000" with the address of your actual application.
2.3 Save and exit the file: Press Ctrl X
, then enter Y
to save changes.
2.4 Create a symbolic link:
sudo ln -s /etc/nginx/sites-available/myapp /etc/nginx/sites-enabled/
- Install PM2:
PM2 is a Node.js process management tool that ensures your Applications continue to run on the server and can recover from failures.
3.1 Install PM2:
sudo npm install -g pm2
3.2 Start your application:
pm2 start app.js
Note: app.js
is the entry file of your application , you need to replace it with your own filename.
3.3 Generate startup script:
pm2 startup systemd
After running this command, you will see a prompt, copy the command it gives into the terminal and run it. This will create a service for PM2 to run automatically on system reboot.
- Configure NGINX reverse proxy:
Now, we need to configure NGINX to forward all traffic to applications launched by PM2.
4.1 Open the NGINX configuration file:
sudo nano /etc/nginx/nginx.conf
4.2 Modify the configuration file:
http{ ... server { listen 80; server_name your_domain.com; location / { proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host $host; proxy_pass http://localhost:3000; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection 'upgrade'; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_cache_bypass $http_upgrade; } } ... }
Note: Replace "your_domain.com" with your domain name, "http:// localhost:3000" with your application address.
- Restart NGINX and PM2:
After completing the above configuration, we need to restart NGINX and PM2 for the changes to take effect.
5.1 Restart NGINX:
sudo systemctl restart nginx
5.2 Restart PM2:
pm2 restart all
At this point, we have successfully deployed NGINX and PM2 on the VPS server. NGINX acts as a reverse proxy and forwards all traffic to applications started by PM2, thus improving the performance and stability of the website. In the future development and maintenance process, you can use other functions of PM2, such as log management and monitoring.
Summary:
This article details how to deploy NGINX and PM2 on a VPS server and provides specific code examples. These tools can help you improve the performance and stability of your website and are essential tools in the website deployment process. I hope this article can help you and make your website better!

You can query the Docker container name by following the steps: List all containers (docker ps). Filter the container list (using the grep command). Gets the container name (located in the "NAMES" column).

How to configure Nginx in Windows? Install Nginx and create a virtual host configuration. Modify the main configuration file and include the virtual host configuration. Start or reload Nginx. Test the configuration and view the website. Selectively enable SSL and configure SSL certificates. Selectively set the firewall to allow port 80 and 443 traffic.

How to configure an Nginx domain name on a cloud server: Create an A record pointing to the public IP address of the cloud server. Add virtual host blocks in the Nginx configuration file, specifying the listening port, domain name, and website root directory. Restart Nginx to apply the changes. Access the domain name test configuration. Other notes: Install the SSL certificate to enable HTTPS, ensure that the firewall allows port 80 traffic, and wait for DNS resolution to take effect.

The methods that can query the Nginx version are: use the nginx -v command; view the version directive in the nginx.conf file; open the Nginx error page and view the page title.

How to confirm whether Nginx is started: 1. Use the command line: systemctl status nginx (Linux/Unix), netstat -ano | findstr 80 (Windows); 2. Check whether port 80 is open; 3. Check the Nginx startup message in the system log; 4. Use third-party tools, such as Nagios, Zabbix, and Icinga.

Create a container in Docker: 1. Pull the image: docker pull [mirror name] 2. Create a container: docker run [Options] [mirror name] [Command] 3. Start the container: docker start [Container name]

Starting an Nginx server requires different steps according to different operating systems: Linux/Unix system: Install the Nginx package (for example, using apt-get or yum). Use systemctl to start an Nginx service (for example, sudo systemctl start nginx). Windows system: Download and install Windows binary files. Start Nginx using the nginx.exe executable (for example, nginx.exe -c conf\nginx.conf). No matter which operating system you use, you can access the server IP

Docker container startup steps: Pull the container image: Run "docker pull [mirror name]". Create a container: Use "docker create [options] [mirror name] [commands and parameters]". Start the container: Execute "docker start [Container name or ID]". Check container status: Verify that the container is running with "docker ps".
