LAMP is an acronym for four open source software frequently used to develop the web applications (such as forums, blogs, and business sites):
- Linux operating system
- Apache web server
- MySQL/MariaDB relational database management system (RDBMS)
- PHP server-side programming language
This tutorial shows you how to install LAMP (Apache version 2, PHP version 7, MariaDB version 10.2) stack on a Debian 9 Linux server along with firewall settings to open tcp port 80, 22, and 443.
Step 1: Apply patches if any
Type the following apt-get command/apt command to update the system:
$ sudo apt update
Sample outputs:
Hit:1 http://security.debian.org stretch/updates InRelease Hit:2 http://cdn-fastly.deb.debian.org/debian stretch InRelease Reading package lists... Done Building dependency tree Reading state information... Done 38 packages can be upgraded. Run 'apt list --upgradable' to see them.
To patch it with the latest updates, run:
$ sudo apt-get upgrade
Sample outputs:
Reading package lists... Done Building dependency tree Reading state information... Done Calculating upgrade... Done The following packages will be upgraded: apt bash debconf debian-archive-keyring debianutils dpkg file gcc-6-base init init-system-helpers libapt-pkg5.0 libc-bin libc-l10n libc6 libcryptsetup4 libdns-export162 libelf1 libgcc1 libgcrypt20 libisc-export160 libmagic-mgc libmagic1 libpam-modules libpam-modules-bin libpam-runtime libpam0g libssl1.0.2 libssl1.1 libstdc++6 libsystemd0 libudev1 locales login multiarch-support passwd perl-base systemd systemd-sysv 38 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

Step 2: Install Apache http server
Type the following command:
$ sudo apt install apache2
Sample outputs:
Reading package lists... Done Building dependency tree Reading state information... Done The following additional packages will be installed: apache2-bin apache2-data apache2-utils libapr1 libaprutil1 libaprutil1-dbd-sqlite3 libaprutil1-ldap liblua5.2-0 ssl-cert Suggested packages: www-browser apache2-doc apache2-suexec-pristine | apache2-suexec-custom openssl-blacklist The following NEW packages will be installed: apache2 apache2-bin apache2-data apache2-utils libapr1 libaprutil1 libaprutil1-dbd-sqlite3 libaprutil1-ldap liblua5.2-0 ssl-cert 0 upgraded, 10 newly installed, 0 to remove and 0 not upgraded. Need to get 0 B/2143 kB of archives. After this operation, 7137 kB of additional disk space will be used. Do you want to continue?

You can view default page by typing the IP address of your server. To find the IP address of your server use the ip command/ifconfig command as follows:
$ ifconfig eth0
$ ip a show eth0
$ ip a show eth0 | grep -w inet
Sample outputs:
inet 10.114.13.8/24 brd 10.114.13.255 scope global eth0
Fire a web browser and type the following url:
http://10.114.13.8
Sample outputs:
Fig.01: Default Debian 9 Apache 2 page
$ sudo vi /var/www/html/index.html
How do I stop/start/restart/reload Apache HTTP server?
The syntax is as follows:
$ sudo systemctl {start|stop|restart|reload|status|graceful-stop|force-reload} apache2
To stop Apache 2 server, run:
$ sudo systemctl stop apache2
To start Apache 2 server, run:
$ sudo systemctl start apache2
To restart Apache 2 server, run:
$ sudo systemctl restart apache2
To reload Apache 2 server, run:
$ sudo systemctl reload apache2
To see status of Apache 2 server, run:
$ sudo systemctl status apache2
Fig.02: Controlling Apache 2 server with systemctl command
How do I change configuration of Apache HTTP server?
You need to edit files located in /etc/apache2/ directory:
$ cd /etc/apache2/
$ ls -l
Sample outputs:
total 32
-rw-r--r-- 1 root root 7224 Jan 25 22:59 apache2.conf drwxr-xr-x 2 root root 7 Jun 13 18:46 conf-available drwxr-xr-x 2 root root 7 Jun 13 18:46 conf-enabled -rw-r--r-- 1 root root 1782 Jan 25 21:16 envvars -rw-r--r-- 1 root root 31063 Jan 25 21:16 magic drwxr-xr-x 2 root root 138 Jun 13 18:46 mods-available drwxr-xr-x 2 root root 31 Jun 13 18:46 mods-enabled -rw-r--r-- 1 root root 320 Jan 25 21:16 ports.conf drwxr-xr-x 2 root root 4 Jun 13 18:46 sites-available drwxr-xr-x 2 root root 3 Jun 13 18:46 sites-enabled
You need to edit or add a new config file in /etc/apache2/conf-available/ directory. Here is a default config file:
$ cat /etc/apache2/sites-enabled/000-default.conf
Sample outputs:
<VirtualHost *:80> # The ServerName directive sets the request scheme, hostname and port that # the server uses to identify itself. This is used when creating # redirection URLs. In the context of virtual hosts, the ServerName # specifies what hostname must appear in the request's Host: header to # match this virtual host. For the default virtual host (this file) this # value is not decisive as it is used as a last resort host regardless. # However, you must set it for any further virtual host explicitly. #ServerName www.example.com ServerAdmin webmaster@localhost DocumentRoot /var/www/html # Available loglevels: trace8, ..., trace1, debug, info, notice, warn, # error, crit, alert, emerg. # It is also possible to configure the loglevel for particular # modules, e.g. #LogLevel info ssl:warn ErrorLog ${APACHE_LOG_DIR}/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined # For most configuration files from conf-available/, which are # enabled or disabled at a global level, it is possible to # include a line for only one particular virtual host. For example the # following line enables the CGI configuration for this host only # after it has been globally disabled with "a2disconf". #Include conf-available/serve-cgi-bin.conf </VirtualHost> # vim: syntax=apache ts=4 sw=4 sts=4 sr noet
See Apache Name Based VirtualHost Example for more info on how to configure virtual hosting on Debian 9.
Step 3: Install MariaDB server
MariaDB is RDBMS and drop in replacement for original MySQL server. It is one of the most popular database servers in the world. It’s made by the original developers of MySQL and guaranteed to stay open source. To install MariaDB server, run:
$ sudo apt install default-mysql-server
OR
$ sudo apt install mariadb-server
Sample outputs:
Reading package lists... Done Building dependency tree Reading state information...

How do I secure MariaDB mysql server?
Type the following command:
$ sudo mysql_secure_installation
Sample session:
Fig.03: Keeping your MariaDB database server safe
Please note that MariaDB/mysql root account and system root account are two different accounts. This is not the root account used for your server management. So make sure you set different passwords.
How do I test my MariaDB installation?
Type the following command:
$ mysql -u root -p
You will greeted with MariaDB mysql prompt. You can type sql commands to see databases, version and much more:
MariaDB [(none)]> show databases;
MariaDB [(none)]> exit

Step 4: Install PHP version 7
PHP version 7 is at least 30-50% faster as compare to PHP 5.6. So let us install PHP version 7 along with php modules for on a Debian 9 server:
$ sudo apt install php7.0 libapache2-mod-php7.0 php7.0-mysql php7.0-gd php7.0-opcache
Sample outputs:
Reading package lists... Done Building dependency tree Reading state information... Done The following additional packages will be installed: fontconfig-config fonts-dejavu-core libfontconfig1 libfreetype6 libgd3 libjbig0 libjpeg62-turbo libpng16-16 libtiff5 libwebp6 libx11-6 libx11-data libxau6 libxcb1 libxdmcp6 libxpm4 php-common php7.0-cli php7.0-common php7.0-json php7.0-readline Suggested packages: php-pear libgd-tools The following NEW packages will be installed: fontconfig-config fonts-dejavu-core libapache2-mod-php7.0 libfontconfig1 libfreetype6 libgd3 libjbig0 libjpeg62-turbo libpng16-16 libtiff5 libwebp6 libx11-6 libx11-data libxau6 libxcb1 libxdmcp6 libxpm4 php-common php7.0 php7.0-cli php7.0-common php7.0-gd php7.0-json php7.0-mysql php7.0-opcache php7.0-readline 0 upgraded, 26 newly installed, 0 to remove and 0 not upgraded. Need to get 0 B/8,129 kB of archives. After this operation, 25.9 MB of additional disk space will be used. Do you want to continue? [Y/n] y debconf: delaying package configuration, since apt-utils is not installed Selecting previously unselected package libxau6:amd64. (Reading database ... 15880 files and directories currently installed.) Preparing to unpack .../00-libxau6_1%3a1.0.8-1_amd64.deb ... .... .. .. Setting up libx11-6:amd64 (2:1.6.4-3) ...

Processing triggers for libapache2-mod-php7.0 (7.0.19-1) ...
This will install:
- PHP version 7 for Apache 2
- PHP 7 mysql connectivity module
- PHP 7 OpCache module to speed up scripts
- PHP 7 GD module for graphics
You can search and install additional PHP modules using the following syntax:
## [search php7 modules] ##
$ apt-cache search php7 | grep module
$ apt search php7 | grep mysql
$ apt-cache search php7 | egrep 'mysql|gd|zip'
$ apt-cache search php7 | more
$ apt search php7 | more
## [search php7 modules] ##
$ sudo apt install {module-name-here}
Finally, restart Apache 2 HTTP server, run:
$ sudo systemctl restart apache2
To test PHP installation, create a script called test.php in /var/www/html/ directory:
$ sudo vi /var/www/html/test.php
Append the following PHP code in it:
<?php phpinfo(); ?>
Fire a web-browser and type the following url:
http://10.114.13.8/test.php
Sample outputs:
Fig.05: Testing PHP 7 with Apache 2
At this stage you have a full fledged LAMP server running a Debian 9.
Step 5: Configure firewall to open port 80 and 443
Type the following command to install ufw firewall frontend:
$ sudo apt install ufw
Sample outputs:
Reading package lists... Done Building dependency tree Reading state information... Done The following NEW packages will be installed: ufw 0 upgraded, 1 newly installed, 0 to remove and 0 not upgraded. Need to get 164 kB of archives. After this operation, 848 kB of additional disk space will be used.

Processing triggers for systemd (232-25) ... Processing triggers for man-db (2.7.6.1-2) ... Processing triggers for rsyslog (8.24.0-1) ...
You must allow access to SSH port 22:
$ sudo ufw allow 22
Rules updated
Rules updated (v6)
Open port 80 and 443
$ sudo ufw allow 80
$ sudo ufw allow 443
Now you have default policy and ssh port including 80/443 allowed. It is safe to start enable the firewall, enter:
$ sudo ufw enable
Sample outputs:
Command may disrupt existing ssh connections. Proceed with operation (y|n)? y Firewall is active and enabled on system startup
To see firewall rules, run:
$ sudo ufw status verbose
Sample outputs:
Status: active Logging: on (low) Default: deny (incoming), allow (outgoing), disabled (routed) New profiles: skip To Action From -- ------ ---- 22 ALLOW IN Anywhere 80 ALLOW IN Anywhere 443 ALLOW IN Anywhere 22 (v6) ALLOW IN Anywhere (v6) 80 (v6) ALLOW IN Anywhere (v6) 443 (v6) ALLOW IN Anywhere (v6)
And there you have it, LAMP installed and running sucessfully on a Debian 9 system. Take a look at other tutorials for more info:
