Environment of lamp development (2014.12.7 under Ubuntu)

Build lamp environment under Ubuntu

Before learning PHP scripting language, you must first build and familiar with the development environment, there are many kinds of development environment, such as lamp, WAMP, Mamp and so on. Here I build the lamp environment, that is, Linux, Apache, MySQL, PHP environment. There are many ways to build online, but they are not up-to-date, the construction time is 2014.12.07.

I. Building the Environment
Lenovo Y470
VMWare9.0
Ubuntu 14.04.1 LTS (trusty Tahr): Ubuntu-14.04.1-desktop-i386.iso
Second, install the software
1. Install Apache2:

sudo Install apache2

After the installation is complete, run the following command to restart Apache:sudo/etc/init.d/apache2 Restart, enter in the browser
http://localhost or http://127.0.0.1, you'll see "It works!" Description Apache installation succeeded.

2. Install PHP:

sudo Install PHP5

3. Install MySQL:

sudo Install mysql-serversudoinstall mysql-client

During the installation process, you will be asked to set the MySQL server password and enter it.

4. Installing phpMyAdmin

sudo Install phpMyAdmin

Select Apache2 during installation, click OK, next choose to configure the database and enter the password.

5 Installing the Expansion module

sudo Install // latest version, automatically installed sudo install libapache2-mod-auth-mysqlsudoinstall php5-mysql sudo Install PHP5-GD

6 Adding test modules

sudo chmod 777 /var/www                            // Modify Permissions sudoln -s/usr/share/phpmyadmin/var/www  // establishing a soft connection

Enter Http://localhost/phpmyadmin in the browser, if the database management software appears, indicating success.

Three test pages

1 Enabling the Mod_rewrite module

sudo A2enmod rewrite sudo // or sudo service apache2 restart restart Apache server:

2 set Apache support. htm. html. php

sudo gedit/etc/apache2/apache2.confaddtype application// Add

3 Testing PHP Web pages

 /*  lamp.php   <? php   $link  = mysql_connect  ("localhost", " Root "," password "); //  note Modify your own password  if  (!  $link  )  die  (' Could not connect: '. mysql_error   ());  else  echo  "Mysql configuration is correct!"  mysql_close  ( $link  ? 

Storing the code in/var/www/html/and accessing http://localhost/lamp.php shows that ' Mysql is configured correctly ' means that the configuration is correct.

Four Common Files

Error 1:

Execute command: sudo/etc/init.d/apache2 restart
Error occurred: Apache2:could not reliably determine the server ' s fully qualified domain name, using

Error 2:

Error 4:

An error occurred: The requested url/phpinfo.php is not found on this server.

Workaround:

1 The above error appears, check the log (/var/log/apache2/error.log, find the purpose of the system lookup
It's/var/www/html.
2 Put your custom files in the /var/www/html

Note: You can also refer to:/etc/apache2/sites-available/dafault.conf, establish a custom virtual server to resolve this issue, the next section will focus on.
