Installing Apache2 With PHP5 And MySQL Support On Debian Wheezy
This tutorial exists for these OS versions
On this page
LAMP is short for Linux, Apache, MySQL, PHP. This tutorial shows how you can install an Apache2 webserver on a Debian Wheezy server with PHP5 support (mod_php) and MySQL support.
I do not issue any guarantee that this will work for you!
1 Preliminary Note
In this tutorial, I use the hostname server1.example.com with the IP address 192.168.0.100. These settings might differ for you, so you have to replace them where appropriate.
2 Installing MySQL 5
First we install MySQL 5 like this:
apt-get install mysql-server mysql-client
You will be asked to provide a password for the MySQL root user - this password is valid for the user [email protected] as well as [email protected], so we don't have to specify a MySQL root password manually later on:
New password for the MySQL "root" user: <-- yourrootsqlpassword
Repeat password for the MySQL "root" user: <-- yourrootsqlpassword
3 Installing Apache2
Apache2 is available as a Debian package, therefore we can install it like this:
apt-get install apache2
Now direct your browser to http://192.168.0.100, and you should see the Apache2 placeholder page (It works!):
Apache's default document root is /var/www on Debian, and the configuration file is /etc/apache2/apache2.conf. Additional configurations are stored in subdirectories of the /etc/apache2 directory such as /etc/apache2/mods-enabled (for Apache modules), /etc/apache2/sites-enabled (for virtual hosts), and /etc/apache2/conf.d.
4 Installing PHP5
We can install PHP5 and the Apache PHP5 module as follows:
apt-get install php5 libapache2-mod-php5
We must restart Apache afterwards:
5 Testing PHP5 / Getting Details About Your PHP5 Installation
The document root of the default web site is /var/www. We will now create a small PHP file (info.php) in that directory and call it in a browser. The file will display lots of useful details about our PHP installation, such as the installed PHP version.
Now we call that file in a browser (e.g. http://192.168.0.100/info.php):
As you see, PHP5 is working, and it's working through the Apache 2.0 Handler, as shown in the Server API line. If you scroll further down, you will see all modules that are already enabled in PHP5. MySQL is not listed there which means we don't have MySQL support in PHP5 yet.
6 Getting MySQL Support In PHP5
To get MySQL support in PHP, we can install the php5-mysql package. It's a good idea to install some other PHP5 modules as well as you might need them for your applications. You can search for available PHP5 modules like this:
apt-cache search php5
Pick the ones you need and install them like this:
apt-get install php5-mysql php5-curl php5-gd php5-intl php-pear php5-imagick php5-imap php5-mcrypt php5-memcache php5-ming php5-ps php5-pspell php5-recode php5-snmp php5-sqlite php5-tidy php5-xmlrpc php5-xsl
Now restart Apache2:
APC is a free and open PHP opcode cacher for caching and optimizing PHP intermediate code. It's similar to other PHP opcode cachers, such as eAccelerator and Xcache. It is strongly recommended to have one of these installed to speed up your PHP page.
APC can be installed as follows:
apt-get install php-apc
Now restart Apache:
Now reload http://192.168.0.100/info.php in your browser and scroll down to the modules section again. You should now find lots of new modules there, including the MySQL module:
phpMyAdmin is a web interface through which you can manage your MySQL databases. It's a good idea to install it:
apt-get install phpmyadmin
You will see the following questions:
Web server to reconfigure automatically: <-- apache2
Configure database for phpmyadmin with dbconfig-common? <-- No
Afterwards, you can access phpMyAdmin under http://192.168.0.100/phpmyadmin/:
