New to linux-build lamp

Learn about linux-build lamp-Linux Enterprise Application-Linux server application. For more information, see the following section. From: andrewxiao
I recently started to learn linux. As the saying goes, my good memory is not as bad as my head. So I decided to record what I learned on weekdays for review. Because I am a beginner, I have used a lot of online materials for reference. However, I wrote a record of my thoughts and multiple experiments here. If there is any problem, I also hope you can point out that I would be grateful!

Today we record the entire process of installing lamp: the platform is centos4.6 + httpd-2.2.9 + mysql-5.0.51b + php-5.2.6

The Development Tools must be installed on the host; otherwise, subsequent compilation cannot be performed.

1. Install Mysql

Go to the mysql decompressed source code file directory:

Cd/usr/src

Tar xvzf mysql-5.0.51b.tar.gz

Cd mysql-5.0.51b

You can enter./configure -- help to view available options:

Compile and install:
./Configure -- prefix =/usr/local/mysql # Set the installation path of mysql
Make & make install # compile and install.
Configure mysql
Groupadd mysql # Add a mysql Group
Useradd-g mysql # Add a mysql user and add it to the mysql Group
Cd/usr/local/mysql/# Switch to the cd/usr/local/mysql/directory
Chown-R root. # change the owner of the current directory to the root user.
Chgrp-R mysql. # change the group owner of the current directory to the mysql group.
Chmod 755. # change the root directory permission

Cp/usr/src/mysql-5.0.51b/support-files/my-medium.cnf/etc/my. cnf

# Copy this file as A/etc/my. cnf file (you can select different files based on the size of the website)
Cd bin/# To the/usr/local/mysql/bin directory
./Mysql_install_db -- user = mysql # initialize the database as mysql (reducing the risk caused by root user Startup)

./Mysqld_safe -- user = mysql & # Start the database with a mysql user (& indicates execution in the background)
./Mysqladmin-u root password 'admin' # Set the root user password of mysql to admin

Cd/usr/local/mysql

Chown-R mysql: mysql var # change the owner and group of var to mysql and mysql; (var is the path for storing mysql database files)

Chmod 755 var # modify the permissions of the var directory;
Cp/usr/src/mysql-5.0.51b/support-files/mysql. server \

>/Etc/init. d/mysqld (same line) # copy the file for automatic start upon startup
Chmod 755/etc/init. d/mysqld # Change mysqld permission
Chkconfig -- add mysqld # add the mysqld service to the System
Chkconfig mysqld on # Start the myslqd service at the default level

Service mysqld restart # restart the mysqld service
Test mysql:
Cd/usr/local/mysql/bin # Switch to the cd/usr/local/mysql/bin directory
./Mysql-u root-p # log on to mysql
Show databases; # view database tables

2. install Apache
First, check whether the apache that comes with linux is installed. If yes, uninstall it.
Command: rpm-qa | grep httpd # Check whether http software is installed
Rpm-e -- nodeps software name # uninstall the software without checking the dependency
Go to the source code directory after Apache Decompression

Cd/usr/src

Tar xvzf httpd-2.2.9.tar.gz

Cd httpd-2.2.9

You can enter./configure -- help to view available options:

Compile and install:

./Configure

-- Sysconfdir =/etc/# specify the path for storing Apache configuration files

-- With-mysql =/usr/local/mysql/# specify the mysql path;

-- Enable-modules # enable all modules.

(The above configuration is the same line! In this case, apache is installed in the default/usr/local/apache2 directory)

Make & make install # compile and install.

Configure Apache
Vi/etc/httpd. conf

Modify ServerName to make this line take effect. Add ip addresses, domain names, and ports.

Example: ServerName 127.0.0.1: 80

Modify DocumentRoot and change the path to your local settings, such as "/var/www/html/" in this example /". And the following lines Change Deny from all in to Allow from all.

Create an index.html file:

Echo "hi, welcome to here">/var/www/html/index.html
Test Apache:
Enter your own ip address and port in the browser for testing.
For example, enter http: // 127.0.0.1: 80 in the browser.

3. install Php
Go to the php decompressed source code file directory (the following configuration is in the same line !)
./Configure

-- Prefix =/usr/local/php # specify the php installation directory

-- With-mysql =/usr/local/mysql # specify the mysql installation directory -- with-apxs2 =/usr/local/apache2/bin/apxs # specify the apache directory.

Make & make install # compile and install.
Cp php. ini-dist/usr/local/php/lib/php. ini

Vi/etc/httpd. conf
Find "# AddType application/x-gzip. gz. tgz"
And add
AddType application/x-httpd-php. php
AddType application/x-httpd-php-source. phps
# The purpose of these two lines is to enable apache to recognize php.
Find "DirectoryIndex index.html"
Add index. php to make index. php a response page.

Test environment:
# Vi/var/www/html/index. php

Input:
Phpinfo ();
?>

# Service httpd restart apache server

For example, enter http: // 127.0.0.1/index. php In the browser to test the function. If it succeeds, related php instructions are displayed, and the source code is displayed if it fails.
