$ apt-get install nginx

you should see your nginx default page (check aws settings for public ip)

nginx commands you might need later
$ service nginx status

your root directory is : /usr/share/nginx/html/

check nginx syntax
$ nginx -t

INSTALL MARIADB

https://downloads.mariadb.org/mariadb/repositories/#mirror=ut-austin&distro=Ubuntu&distro_release=xenial–ubuntu_xenial&version=10.1

setup MariaDB repo for version 10.1

$ sudo apt-get install software-properties-common
$ sudo apt-key adv –recv-keys –keyserver hkp://keyserver.ubuntu.com:80 0xF1656F24C74CD1D8
$ sudo add-apt-repository ‘deb [arch=amd64,i386,ppc64el] http://ftp.utexas.edu/mariadb/repo/10.1/ubuntu xenial main’

we are ready to install mariadb 10.1
$ sudo apt update
$ sudo apt install mariadb-server mariadb-client

it will ask for password enter twice on purple screen
never forget this database password

now finish the mariadb installation
$ /usr/bin/mysql_secure_installation

enter current password for root: (the one you entered)
change root password? (type N)
Remove anonymous users? (type Y)
Disallow root login remotely? (type N)
Remove test database and access to it? (type y)
Reload privilage tables now? (type y)

let’s verify mariadb is installed
$ mysql -u root -p

Enter password: (type the root password you given)

now list the databases
$ MariaDB [(none)]> show databases;

+——————–+
| Database |
+——————–+
| information_schema |
| mysql |
| performance_schema |
+——————–+
3 rows in set (0.00 sec)

$ MariaDB [(none)]> exit;
Bye

you can also look at mariadb status
$ sudo service mysql status
Ctrl + C to exit

MariaDB commands
$ sudo service mysql status
$ sudo service mysql start
$ sudo service mysql stop
$ sudo service mysql restart

or

$ systemctl start mysql
$ systemctl enable mysql

INSTALL PHP 7

install all required php 7 files

$ apt-get install php7.0 php7.0-fpm php7.0-mysql php7.0-curl php7.0-gd php7.0-mbstring php7.0-xml php7.0-json php7.0-cli

check version

php-fm commands
$ systemctl start php7.0-fpm
$ systemctl stop php7.0-fpm
$ systemctl status php7.0-fpm
$ systemctl restart php7.0-fpm

edit php-fpm config file
$ sudo vi /etc/php/7.0/fpm/php.ini

change time zone and fix_pathinfo

cgi.fix_pathinfo=1

restart php-fpm

$ systemctl restart php7.0-fpm

add index.php to the index on nginx default ini file
$ vi /etc/nginx/sites-available/default

index index.php index.html index.htm index.nginx-debian.html;
server_name ip;

ADDING MULTIPLE SITES TO THE SERVER

You can create multiple web sites under the root directory /usr/share/nginx/html/
Just create your website directory under root, let’s say it’s called getyanji

first create the working directory
$ mkdir /usr/share/nginx/html/getyanji

We won’t use default anymore.. etc/nginx/sites-enabled/default

create server files from default
$ cp /etc/nginx/sites-available/default /etc/nginx/sites-available/getyanji

create links to the enabled sites
$ sudo ln -s /etc/nginx/sites-available/getyanji /etc/nginx/sites-enabled/

you later use the sites’ own config files
$ sudo vi /etc/nginx/sites-available/getyanji

Repeat the above step for another new website!

TEST PHP

Note: Your document root is usr/share/nginx/html/

let’s create an info php file to show the php settings
$ vi /usr/share/nginx/html/getyanji/info.php

type this save and close the file:

check out php info page
http://public_ip/info.php

INSTALL PHPMYADMIN

$ apt-get update
$ apt-get install phpmyadmin

In purple screen it asks apache or lighttpd, we will select neither of it, press Tab key on your keyboard to skip to the OK button, then press enter
Configure database for phpymadmin with dbconfig-common? (press Yes)
enter same passwords you entered before (3 times) The first password is actually the phpmyadmin web login password but we make it the same to avoid confusion

now let the nginx server finds the location of phpmyadmin
$ ln -s /usr/share/phpmyadmin /usr/share/nginx/html/getyanji

$ phpenmod mcrypt
$ phpenmod mbstring

then security limit extensions
$ vi /etc/php/7.0/fpm/pool.d/www.conf

security.limit_extensions = .php .php3 .php4 .php5

restart web server
$ service nginx restart
restart php-fpm
$ systemctl restart php7.0-fpm

now you should see your phpmadmin page, login with root username and password you have given before
http://public_ip/phpmyadmin
