sudo service apache2 stop

Ii. PHP
1. install php (recommended to install the extended php5-gd php5-mysql ):

sudo apt-get install libapache2-mod-php5 php5

2. Restart apache2 to load the PHP module:

sudo /etc/init.d/apache2 restart

3. The default PHP network server root directory is/var/www. Due to the security principles of the Linux system, the file read and write permissions under this directory only allow the root user to operate. Therefore, we cannot create or modify or delete PHP files in the www folder, you must first modify the read and write permissions of the/var/www directory. You cannot modify the File Permission by right-clicking the attribute in the interface manager. You must run the root terminal command:

sudo chmod 777 /var/www

Then you can write html or PHP files.

4. Create a test. PHP file under the Web directory to test whether PHP can run normally:

sudo gedit /var/www/test.php

Then enter:

Save the file and enter http: // 127.0.0.1/test. php In the browser. If "hello, world!" is displayed !! "And php information, as shown in:

AddDefaultCharset UTF-8

Restart Apache2 and refresh the webpage.

Iii. MySQL
1. Install the mysql database (apt-get will automatically download and install the latest mysql version ):

sudo apt-get install mysql-server mysql-client

At the end of the installation, enter the root password (the root password is not the Ubuntu root password, but the root password you want to set for MySQL ).

Note: The MySQL configuration file is in the/etc/mysql directory.

To avoid Chinese garbled characters, change the default character set to UTF-8, modify the/etc/mysql/my. cnf file, and add the following in the corresponding location:

[client]default-character-set=utf8[mysql]default-character-set=utf8[mysqld]collation-server = utf8_unicode_ciinit-connect='SET NAMES utf8'character-set-server = utf8

2. Create the testmysql. php file in the/var/www directory and test the connection of php to MySQL. The file content is as follows:

Access testmysql. php In the browser. If the connection is successful, "MySQL connection succeeded" is displayed ".

3. Install phpmyadmin-Mysql Database Management

Set the password for phpmyadmin to register the database:

Then, establish a symbolic connection between phpmyadmin and apache2, because the www directory is in the/var/www directory, and phpmyadmin is in the/usr/share/phpmyadmin directory, so:

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

Phpmyadmin test: Open http: // localhost/phpmyadmin and you will see the phpMyAdmin logon interface, as shown in:
