The lamp architecture evolves to LAMPGC and then to LNMLGC (LINUX+NGINX+MYSQL+LUA+GEARMAN+C)

Lamp is a public structure, linux+apache+mysql+php.

In the architecture of our system, we have made further progress, linux+apahce+mysql+php+gearman+c

PHP as a page display

Core business logic is implemented by C language, and PHP calls C task through Gearman middleware

Because Apache is not very force-efficient in high concurrency, we further evolve in scenarios where high concurrency is required, linux+nginx+mysql+php+lua+gearman+c

The page section is displayed by NGINX+FASTCGI+PHP-FPM.

High concurrent business calls are implemented by Nginx+lua+gearman+c

Here, we highlight how Nginx calls Gearman middleware.

First look at the situation of apache+php call Gearman, synchronous call a Gearman task, if this task to 3S clock, then the current Apache httpd process will be blocked, it can not serve other clients

Nginx in high concurrent asynchronous invocation of the sex can be strong, this earth people know

Lua can also implement concurrent asynchronous calls

Let's take a look at the implementation of Nginx+lua call Gearman:

Nginx is also a worker,worker process to invoke the Gearman task through the LUA coprocessor, even if the task is 3S clock, in this 3 S-clock The worker process can serve other clients, This relies on the benefits of Nginx's Epoll event-triggering non-blocking calls and the LUA asynchronous invocation, which enables high-concurrency business calls.

The following is a Lua-nginx-module installation and simple configuration process:
