This article mainly introduces "how to understand Phusion Passenger Application Server". In daily operation, I believe many people have doubts about how to understand Phusion Passenger Application Server. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the doubts about "how to understand Phusion Passenger Application Server"! Next, please follow the editor to study!

Problem description

Many times, when we solve the A problem, we will inadvertently find the B tool. Maybe this tool has nothing to do with solving problem A, but we still choose to simply understand the tool, increase our knowledge reserve and broaden our horizons.

In fact, we did not expect that when solving the problem of excessive memory consumption, we would find Web application deployment tools, which can only show that we are not paying attention.

This note will record what Phusion Passenger is and a simple case study that gives us a quick idea of how to use Phusion Passenger.

A sample solution is the best place to start explaining the tool

Obviously this is a segment of Nginx configuration, and there is an unknown passenger_* configuration line, and it is also clear that it has something to do with NodeJS:

Server {listen 80; server_name yourserver.com; # Tell Nginx and Passenger where your app's' public' directory is root / path/to/app/public; # Turn on Passenger passenger_enabled on; # Tell Passenger that your app is a Node.js app passenger_app_type node; passenger_startup_file app.js;}

If we want to deploy NodeJS applications in the traditional way, we need to:

1) run node app.js to start the operation (also consider the management of the service, automatic startup, etc.)

2) then configure Nginx proxy_pass forwarding and related parameters

Using Passenger makes it easier to operate, only by:

1) install the Passenger module for Nginx

2) then, add the application-related configuration to the nginx.conf

2) finally, start the Nginx service, and the application starts with it

This is what attracts us to Passenger. It simplifies the way we manage Web applications.

Functions and characteristics

Passenger is not only that, it has many other features:

1) support Python NodeJS Ruby language

2) Security enhancement, which can prevent common attacks

3) Application monitoring, monitoring application performance, crashes, hangs, memory leaks, etc.

4) problem analysis, solving application problems through request checking, backtracking dump CPU and memory status

5).

At this point, the study on "how to understand Phusion Passenger Application Server" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
