Build LAMP service by compiling source code

# LAMP introduction #

LAMP architecture is one of the current mature enterprise website application models, which refers to a complete set of systems and systems that work together.

Related software, can provide dynamic Web site services and application development environment. LAMP is an acronym with

The body includes Linux operating system, Apache website server, MySQL database server, PHP (or Perl,

Python) web programming language. This chapter will build a LAMP environment by compiling source code, which can meet the requirements of enterprises.

The need for institutionalization.

When building the LAMP platform, the installation order of each component is Linux, Apache, MySQL, PHP.

Among them, the installation of Apache and MySQL is not in strict order, while the installation of PHP environment is generally placed at the end.

Responsible for communicating with Web server and database system to work together.

# introduction to Apache #

"Apache HTTP Server" is an outstanding representative of open source software projects, provided by the standards-based HTTP network protocol.

Web browsing services have long maintained more than half of the share in the field of Web servers. Apache server can transport

Line in Linux, UNIX, Windows and other operating system platforms.

Apache server is a software formed by the integration and improvement of several Web server programs that appeared before.

Item, whose name comes from "A Patchy Server", which means "to modify based on the code of the original Web service program."

D) after the formation of the server program.

In 1995, the Apache service released version 1.0, and "Apache Group" has been in charge of the project ever since.

Until 1999, the Apache Software Foundation was established on the basis of "Apache Group"

(Apache Software Foundation,ASF). At present, 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, with Web

With the continuous expansion of application requirements, ASF has gradually increased many open source software projects related to Web technology, so Apache

Now it represents not only the Web server, but also many open source software projects managed by ASF. ASF base

The official website of Jinhui is http://www.apache.org/.

"Apache HTTP Server" is one of ASF's famous software projects, and its official name is "httpd", that is,

Is the historical Apache website server. In the following content, use "Apache" or "httpd" unless otherwise specified

They all mean "Apache HTTP Server".

# main features of Apache #

1. Open source: this is one of the important features of the Apache server and the basis for other features.

Apache service programs are jointly maintained by many developers around the world, and anyone is free to use

Use, which fully embodies the spirit of open source software.

2. Cross-platform applications: this feature benefits from the open source code of Apache. Apache server can transport

On most hardware and software platforms, all UNIX operating systems can run Apache services

And even Apache servers run well on most Windows system platforms.

The cross-platform characteristic of Apache server makes it have the condition of being widely used.

3. Support a variety of Web programming languages: the web programming languages supported by Apache servers include Perl, PHP,

Python, Java, and even Microsoft's ASP technology can also be used in Apache servers. Branch

With a variety of commonly used Web programming languages, Apache has a wider range of applications.

4. Modular design: Apache does not centralize all functions within a single service program, but

Implement proprietary functions through standard modules as much as possible, which brings a good

Scalability. Other software developers can write standard module programs to add Apache itself

Other functions that you don't have.

5. The operation is very stable: the Apache server can be used to build Web sites with heavy traffic, very

Many well-known corporate websites use Apache as the Web service software.

6. Good security: Apache server has relatively good security, which is common to open source software.

There are some characteristics. In addition, the Apache maintenance team will provide timely patches for the vulnerabilities that have been discovered.

Provide server programs as secure as possible for all users of Apache.

× × × LAMP experiment

Experimental environment:

1. Virtual machine ip 192.168.32.20-vm1 is connected to the host. Memory 3G (not less than 2G)

Turn off the core protection, turn off the firewall, and build a yum warehouse with CD as the source.

two。 Several packages that need to be installed:

Apache

Mysql

Php

Lab planning:

1. Set up apache service

two。 Set up mysql service

3. Build a PHP running environment

4. Deploy phpmyadmin system

The steps of the experiment:

1. Preliminary setup of experimental environment

[root@localhost ~] # systemctl stop firewalld # turn off the firewall at 00:00

[root@localhost ~] # systemctl disable firewalld # permanently turn off the firewall

Removed symlink / etc/systemd/system/multi-user.target.wants/firewalld.service.

Removed symlink / etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

[root@localhost ~] # setenforce 0 # 00:00 disable core protection

[root@localhost yum.repos.d] # sed-I'/ SELINUX/s/= [a Murz] / = disabled/g' / etc/sysconfig/selinux

# permanently disable core protection

Build a yum warehouse.

[root@localhost ~] # mount / dev/cdrom / mnt # Mount the CD

Mount: / dev/sr0 write protection, which will be mounted as read-only

[root@localhost ~] # cd / etc/yum.repos.d/

[root@localhost yum.repos.d] # mkdir jlh

[root@localhost yum.repos.d] # mv C jlh # move the configuration files to the jlh folder

[root@localhost yum.repos.d] # cp jlh/CentOS-Base.repo local.repo

[root@localhost yum.repos.d] # vi local.repo

[centos]

Name=centos

Baseurl= file:///mnt # its yum download source is not under mnt

Gpgcheck=0

Enabled=1

# gpgkey= file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

two。 Set up apache service

(1) upload three packages of apache services to the opt directory

(2) decompress the compressed package

[root@localhost opt] # tar xf apr-1.6.2.tar.gz # extract the compressed file to the current directory

[root@localhost opt] # tar xf apr-util-1.6.0.tar.gz # extract the compressed file to the current directory

[root@localhost opt] # tar xf httpd-2.4.29.tar.bz2 # extract the compressed file to the current directory

View

(3) move the plug-ins needed to install http to the http/scrlib directory

[root@localhost opt] # mv apr-1.6.2 httpd-2.4.29/srclib/apr

# move the extracted apr-1.6.2 plug-in to the / apr file in the httpd-2.4.29/srclib directory for compilation and installation

[root@localhost opt] # mv apr-util-1.6.0 httpd-2.4.29/srclib/apr-util

# move the extracted apr-util-1.6.0 plug-in to the / apr-util file in the httpd-2.4.29/srclib directory

(4) configuration (custom personalized configuration)
