Linux under compilation installation httpd

What to learn in this chapter

--------- introduction httpd

----------rpm differs from Yum

---------- compile and install advantages

---------- compiling httpd

1. The relationship between Apache and HTTP

HTTP is a Hypertext Transfer Protocol, and the early Apache team used this protocol to develop a Web services software called HTTP. Later, through the bug repair and improve the function, on the basis of HTTP developed another software, called a patchy Server, referred to as Apache, and the Apache organization exactly the same name. Then the Apache team grew stronger, eventually becoming an open-source Software Foundation (ASF), and HTTP was no longer the only software it maintained, and it was obviously inappropriate to call this service software Apache, so we could call it httpd. But sometimes for historical reasons, we will still use Apache as a Web services software to address, and its we service specification has become the industry standard.

In order to be more rigorous, we use httpd to describe the software.

2, introduce the difference between RPM package and source installation

RPM package is to compile the source code package, as long as the installation can provide services, and the source package is the lowest code, if you want to use, but also compiled, obviously not as easy as RPM package, but the two have advantages, production and life, the source code compiled and installed mostly, if the practice use, RPM package installation mostly.

3. Advantages of compiling and installing

<1> Custom Software Features
<2> optimize compilation parameters to improve performance
<3> resolving unnecessary dependencies between software
<4> easy to clean and unload

4. Compile and install httpd-2.2.29

<1> Preparing development tools, development environments, and development libraries

[Email protected]/media/cdrom/packages] #yum groupinstall "Development Tools"

<2> Prepare source code and unzip to a directory

[Email protected]~] #tar-xf httpd-2.2.29.tar.bz2 [[email protected]~] #cd httpd-2.2.29/[[email protected]~/ Httpd-2.2.29] #du-sh42m # only 42M

You can use the View readme, install, and./configure--help to understand the installation process

<3> execute. Configure scripts, specify attributes, check external environments, and generate specific makefile files based on attributes

  <4>make tool compiles, compiles. C Source code according to makefile file into application

<5>make Install, create a directory and copy files
