ApacheService Introduction and compilation and installation detailed

First,ApacheIntroduction

Apache HTTP Server (Apache), an open source Web server for the Apache Software Foundation, is currently the most widely used Web server in the world and is known for its cross-platform, efficient and stable Can run on almost any widely used computer platform. Apache is characterized by simple, fast, stable performance, and can be used as a proxy server.

Apache is developed in C language based on the modular design of the Web application, the overall appearance of the code is more readable than the PHP code, its core code is not many, most of the functions are divided into various modules, each module is loaded on demand when the system starts.

Supports SSL technology and supports multiple virtual hosts. Apache is a structure based on the prefork mode of the process (and also the thread-based worker pattern), which consumes more system overhead than threads, and is less suited to multiprocessor environments, so when an Apache web site is scaled up, Typically, you increase the server or expand the cluster nodes instead of increasing the processor.

Second,Apachethe characteristics

Apacheweb Server Software has the following features:

1. Support for the latest http/1.1 communication protocol

2. A simple and powerful file-based configuration process

3. Support for Universal Gateway Interface

4. Support IP-based and domain-based virtual hosts

5. Support HTTP authentication in multiple ways

6. Integrated Perl processing module

7. Integrated Proxy Server Module

8. Support real-time monitoring of server status and custom server logs

9. Support server-side include directive (SSI)

10. Support Secure Socket Layer (SSL)

11. Provide tracking of user session process

12. Support FastCGI

13. Javaservlets can be supported by a third-party module

third, compile and installApacheStep and parameter explanation

The compilation and installation of the source code generally consists of 3 steps:

Configuration (configure), typically dependent on the GCC compiler, BINUTILS,GLIBC. Configure software features, check the compilation environment, generate makefile files

Compile (make)

Install (make install)
