Installing Apache2

sudo Install apache2

When the installation is complete, run the following command to restart:

sudo /etc/init.d/apache2 restart

Enter http://localhost or http://127.0.0.1 in the browser, if you see "It works!", it means that Apache installed successfully, Apache default installation, will be under/var set up a directory called WWW, This is the Web directory, all Web files that can be accessed by the browser should be placed in this directory.


1. Install PHP

sudo Install libapache2-mod-php5 php5 php5-gd php5-mysql

After installation, we will restart Apache and let it load the PHP module:

sudo /etc/init.d/apache2 restart

Next, we'll create a new PHP file under the Web directory to test if PHP works properly.

Phpinfo ();?>

Then save the file, enter the http://localhost/test.php in the browser, if there is a page showing the PHP running parameters, it means that PHP is working properly.


2. Install MySQL

sudo Install mysql-server mysql-client-5.1

At the end of the installation, it will require the root password to be entered, note that the root password here is not the root password of Ubuntu, it is the root password you want to set for MySQL.


3, Installation Phpmyadmin-mysql database management

sudo Install phpMyAdmin

phpMyAdmin settings:
During installation, you will be asked to select Web Server:apache2 or LIGHTTPD, select apache2, press TAB, and then OK. You will then be asked to enter the MySQL database password for the setup password Password of the database ' s administrative user.
Then connect phpMyAdmin with Apache2, in my case: the WWW directory is in the/var/www,phpmyadmin directory in/usr/share/phpmyadmin, so just use the command:

sudo LN -s/usr/share/phpmyadmin/var/www

phpMyAdmin test: Open Http://localhost/phpmyadmin in the browser address bar.

The basic components of the above ALMP are installed, let's look at some other settings:
Set Ubuntu file to execute read and write permissions
After the LAMP is assembled and installed, the default settings for the PHP Web server root directory are:/var/www. Because of the security principle of Linux system, the file read and write permission in the directory is only allowed by root user, so we can't create a new php file in www folder or modify or delete it, we must first modify the read and write permission of the/var/www directory. In the interface manager through the right-click property cannot modify the file permissions, you have to execute the root terminal command: sudo chmod 777 /var/www . You can then write to the HTML or PHP file. If the file permissions for 777 are not very clear, refer to the chmod command.
