This page will describe the steps you have to take to install LAMP, which stands for Linux Apache MariaDB PHP. This page will show you, how to set up a working Apache2 webserver, a configured MariaDB database server, to install PHP5, working with Apache, and finally, phpMyAdmin with a configured pmadb database.

This article is updated to reflect the installation in openSUSE 13.1. However it it does not deviate much from lower versions of openSUSE. Getting root access
Every time you want to change anything to the system, you will need root access. You can get this by:
Open a command line program (konsole is the standard one). Type su -
The console will now ask you for the password you selected at the installation, enter that password and press enter again. If you logged in successfully, the user name and the computer name should be displayed in red now.
Setting up Apache2
Installing Apache2
To install software, make sure that you have root access. We will install our software using YaST from the command line.
Open a console. To install apache, we use the command yast -i apache2 or zypper in apache2 .
This also installs the packet apache2-example-pages, which provides an example page when accessing the web server.
Starting Apache2
To start Apache, execute
systemctl start apache2.service
Note: If you ever want to restart apache, execute
systemctl restart apache2.service
or if you want to stop it
systemctl stop apache2.service
This does not start the apache server after a reboot. To enable that, give the command
systemctl enable apache2.service
Testing the installation
Now that you have installed apache2, you want to check if it works. The packet apache2-example-pages installed the file /srv/www/htdocs/index.html, which contains:
<html><body><h1>It works!</h1></body></html>
Note: You can create a new file and edit it by using your favorite editor.
You can now start your favorite browser. Navigate to 'localhost'. You should see 'It works!'. Enabling public access to the web server
In this state the web server is only accessible as localhost. You have to open port http (=80) in the firewall. You can do that using YaST, selecting Security and Users –> Firewall –> Allowed services and add HTTP server. You may also edit the line with FW_CONFIGURATIONS_EXT= in it in the file /etc/sysconfig/SuSEfirewall2 and add apache2 in that line. A space is used in that line to separate elements. After editing you have to restart the firewall using:
systemctl restart SuSEfirewall2.service
Setting up PHP5
Installing PHP5
To install software, you need root access. When you have root access, execute
yast -i php5 php5-mysql apache2-mod_php5 or zypper in php5 php5-mysql apache2-mod_php5
Now you have installed PHP5. Restarting the webserver Now that you have installed PHP5, you have to restart the apache2 webserver to get some results. You can restart apache by executing
systemctl restart apache2.service
with root access.
Testing the installation
That was pretty easy, but now you want to test it out, don't you? So, we go to the htdocs folder again by executing
cd /srv/www/htdocs
Make a new file named index.php and with the following content:
<?php echo "<h1>You succesfully installed PHP5!</h>" ?>
Now, open your favorite browser again and navigate to 'localhost/index.php'. If everything went alright then you should see 'You successfully installed PHP5!'.
Setting up MariaDB
Installing MariaDB
We need to install mariadb and mariadb-tools, mariadb-tools is necessary for the administration, execute
yast -i mariadb mariadb-tools or zypper in mariadb mariadb-tools
with root access. Starting the MariaDB server
MariaDB is an alternative package for MySQL, so further on the name mysql is used. To start the MariaDB server, execute
systemctl start mysql.service
You may want to read the messages issued by the server in /var/log/messages.
Note: If you ever want to restart mysql, execute
systemctl restart mysql.service
or if you want to stop it
systemctl stop mysql.service
This does not start the mysql server after a reboot. To enable that, give the command
systemctl enable mysql.service
==== Configuring the MariaDB/MySql server ====
To set the root password for the first time:
Execute
mysqladmin -u root password NEWPASSWORD
If you want to set the password to root123, type
mysqladmin -u root password root123
If you ever want to change your password later:
Type mysqladmin -u root -p password NEWPASSWORD Your old password will be asked.
Logging in to the client Now you can log in into the server client by executing
mysql -u root -p Enter exit
to go back to the terminal.
Installing phpMyAdmin
What is phpMyAdmin?
phpMyAdmin, or pma is a tool to administrate your databases. The installation process is quite easy.
Installing phpMyAdmin
Install phpMyAdmin by executing
yast -i phpMyAdmin or zypper in phpMyAdmin
This also installs a number of needed php5 modules and restarts the apache2 server.
Logging into phpMyAdmin
To log in to phpMyAdmin:
Navigate to localhost/phpMyAdmin Enter the root username and the root password of your mysql server Click on the 'go' button
==== Configuring phpMyAdmin ====
To configure phpMyAdmin, we need to edit the configuration file. It is found in /etc/phpMyAdmin/config.inc.php.
Open the file and change corresponding lines to (note the double underscore in the names of the tables):
$cfg['Servers'][$i]['controluser'] = 'somename'; $cfg['Servers'][$i]['controlpass'] = 'somepassword'; /*Advanced phpMyAdmin features */ $cfg['Servers'][$i]['pmadb'] = 'phpmyadmin'; $cfg['Servers'][$i]['bookmarktable'] = 'pma__bookmark'; $cfg['Servers'][$i]['relation'] = 'pma__relation'; $cfg['Servers'][$i]['table_info'] = 'pma__table_info'; $cfg['Servers'][$i]['table_coords'] = 'pma__table_coords'; $cfg['Servers'][$i]['pdf_pages'] = 'pma__pdf_pages'; $cfg['Servers'][$i]['column_info'] = 'pma__column_info'; $cfg['Servers'][$i]['history'] = 'pma__history'; $cfg['Servers'][$i]['tracking'] = 'pma__tracking'; $cfg['Servers'][$i]['designer_coords'] = 'pma__designer_coords';
You will need to change the user name of controluser to the name of a new account (above somename) and controlpass (above somepassword) to it's password. Change the protection of this file so it is owned by root and only readable by group www.
chown root:www /etc/phpMyAdmin/config.inc.php chmod 640 /etc/phpMyAdmin/config.inc.php
Log in to localhost/phpMyAdmin again. Import via the Import tab on the phpMyAdmin page the file /usr/share/doc/packages/phpMyAdmin/example/create_tables.sql There is a comment telling you that a user pma should be present already, however this is not necessary. Log in and out again using user name root and the root password of MySQL. Select the tab Users and press Add user. Enter as new user name the name of controluser chosen above, localhost as host, twice the above chosen password in the corresponding fields and press Go (below right). Create a file with the following content, where somename and somepassword are replaced by the above chosen values.
GRANT USAGE ON mysql.* TO 'somename'@'localhost' IDENTIFIED BY 'somepassword';
GRANT SELECT (
Host, User, Select_priv, Insert_priv, Update_priv, Delete_priv,
Create_priv, Drop_priv, Reload_priv, Shutdown_priv, Process_priv,
File_priv, Grant_priv, References_priv, Index_priv, Alter_priv,
Show_db_priv, Super_priv, Create_tmp_table_priv, Lock_tables_priv,
Execute_priv, Repl_slave_priv, Repl_client_priv
) ON mysql.user TO 'someuser'@'localhost';
GRANT SELECT (Host, Db, User, Table_name, Table_priv, Column_priv)
ON mysql.tables_priv TO 'pmagebruiker'@'localhost';
GRANT SELECT ON mysql.db TO 'someuser'@'localhost';
GRANT SELECT, INSERT, UPDATE, DELETE ON phpmyadmin.* TO 'someuser'@'localhost';
and import that file via the Import tab.
Read the documentation on phpMyAdmin on the phpMyAdmin website. Do not forget to take the necessary security measures. You should have a working LAMP server now!
