Theory + experiment-source code compile and install LAMP

Preface

The LAMP architecture is one of the current mature enterprise website application modes. It refers to a set of systems and related software that work together to provide dynamic website services and application development environments. LAMP is an acronym that specifically includes Linux operating system, Apache web server, MySQL database server, PHP (or Perl, Python) web programming language. This chapter will build the LAMP environment by compiling source code, which can meet the needs of enterprise customization.
When building the LAMP platform, the order of installation of each component is Linux, Apache, MySQL, PHP.
There is no strict order for the installation of Apache and MySQL; the installation of the PHP environment is generally put at the end, responsible for communicating with the Web server and database system to work together.

1. How to compile and install Apache

1. Introduction to Apache

"Apache HTTP Server" is an outstanding representative of open source software projects. It provides web browsing services based on the standard HTTP network protocol and has long maintained more than half of the share in the field of web servers. The Apache server can run on multiple operating system platforms such as Linux, UNIX, and Windows.
Apache server is the software formed after the integration and improvement of several Web server programs that appeared before. Its name comes from "A Patchy Server", which means "formed after modification (patches) based on the code of the original Web service program. Server program".
In 1995, the Apache service program released version 1.0. Since then, the "Apache Group" has been responsible for the management and maintenance of the project; until 1999, the Apache Software Foundation (ASF) was established on the basis of the "Apache Group". ). Currently, the Apache project has been managed and maintained by ASF.
ASF is a non-profit organization, initially only responsible for the management of the "Apache Web" server project. As the demand for Web applications continues to expand, ASF has gradually increased many open source software projects related to Web technology, so Apache now represents more than just the Web The server more broadly represents the many open source software projects managed by ASF. The official website of the ASF Foundation is http://www.apache.org/.
"Apache HTTP Server" is one of the well-known software projects under ASF, its official name is "httpd", which is the historical Apache web server. In the follow-up content, unless otherwise specified, using "Apache" or "httpd" refers to "Apache HTTP Server".

2. Features of Apache

(1) Open source code: This is one of the important features of the Apache server and the basis for other features.
The Apache service program is jointly maintained by many developers all over the world, and anyone can
use it freely , which fully reflects the spirit of open source software.
(2) Cross-platform application: This feature benefits from the open source code of Apache. Apache server can run
on most software and hardware platforms, all UNIX operating systems can run Apache server
, and even Apache server can run well on most Windows system platforms.
The cross-platform nature of the Apache server makes it suitable for widespread use.
(3) Support various web programming languages: The web programming languages ​​supported by the Apache server include Perl, PHP,
Python, Java, etc., and even Microsoft's ASP technology can also be used in the Apache server. Supporting a
variety of commonly used Web programming languages ​​enables Apache to have a wider range of applications.
(4) Modular design: Apache does not concentrate all functions in a single service program, but instead
uses standard modules to achieve proprietary functions as much as possible, which brings good
scalability to the Apache server . Other software developers can write standard module programs to add
other functions that Apache does not have.
(5) Very stable operation: Apache server can be used to build Web sites with heavy traffic
Many well-known corporate websites use Apache as their web service software.
(6) Good security: Apache server has relatively good security, which is a common
feature of open source software . In addition, the Apache maintenance team will provide patches for the discovered vulnerabilities in a timely manner to provide
all users of Apache with the most secure server program.
