    HOW TO INSTALL LEMP(PHP 7.2.x, NGINX 1.10.x & MYSSQL5.7) & PHPMYADMIN

Step 1: Install Nginx HTTP Server On Ubuntu

Step 2: Install MySQL to Manage Site Data

Step 3: Install PHP7.2 and PHP7.2-FPM

Step 4: Configure Nginx PHP-FPM Settings

Step 5: phpMyAdmin

---------------Step 1: Install Nginx HTTP Server On Ubuntu---------------

Install software-properties-common package to give us add-apt-repository package

sudo apt-get install -y software-properties-common
Install latest nginx version from community maintained ppa

sudo add-apt-repository ppa:nginx/stable
Update packages after adding ppa

sudo apt-get update
Install nginx

sudo apt-get install -y nginx
Check status

sudo service nginx
Start nginx if it is not already running

sudo service nginx start

---------------Step 2: Install MySQL to Manage Site Data---------------

You can install this easily by typing:

sudo apt-get install mysql-server
You will be asked to supply a root (administrative) password for use within the MySQL system.
The MySQL database software is now installed, but its configuration is not exactly complete yet.
To secure the installation, we can run a simple security script that will ask whether we want to modify some insecure defaults. Begin the script by typing:

mysql_secure_installation

---------------Step 3: Install PHP7.2 and PHP7.2-FPM---------------

check what is the latest PHP version supplied by UBUNTU

sudo apt-cache show php
Add Repository which gives us the latest php version 7.2

sudo add-apt-repository ppa:ondrej/php
Lets now check what is the latest PHP version available now after the repository is added

sudo apt-cache show php
Lets now install php7.2 and some important modules which we will need.

sudo apt-get install php7.2-cli php7.2-fpm php7.2-curl php7.2-gd php7.2-mysql php7.2-mbstring zip unzip
Once done all basic modules will be installed now, lets check the version now

php -v
Lets also check if the PHP7.2-FPM is running, if not start it

sudo service php7.2-fpm status

sudo service php7.2-fpm start  ###### (if the service isn't running already)
Configure the PHP Processor

We now have our PHP components installed, but we need to make a slight configuration change to make our setup more secure.
Open the main php-fpm configuration file with root privileges:

sudo nano /etc/php/7.2/fpm/php.ini
What we are looking for in this file is the parameter that sets cgi.fix_pathinfo. This will be commented out with a semi-colon (;) and set to "1" by default.
This is an extremely insecure setting because it tells PHP to attempt to execute the closest file it can find if the requested PHP file cannot be found. This basically would allow users to craft PHP requests in a way that would allow them to execute scripts that they shouldn't be allowed to execute.
We will change both of these conditions by uncommenting the line and setting it to "0" like this:
/etc/php/7.0/fpm/php.ini
cgi.fix_pathinfo=0

Save and close the file when you are finished.

---------------Step 4: Configure Nginx PHP-FPM Settings---------------

Next, open the Nginx site configuration file… by default it’s stored at /etc/nginx/sites-available/default
If you have a custom file, then edit it to enable Nginx PHP support. Run the commands below to open Nginx default site configuration file
sudo nano /etc/nginx/sites-available/default

Then uncomment or remove the # symbol on the highlighted lines below to enable Nginx PHP support.
server {
    listen 80;
    listen [::]:80;
    root /var/www/html;
    index  index.php index.html index.htm;
    server_name  example.com www.example.com;

    location / {
        try_files $uri $uri/ =404;       
    }

  
     # pass PHP scripts to FastCGI server
        #
        location ~ \.php$ {
               include snippets/fastcgi-php.conf;
        #
        #       # With php-fpm (or other unix sockets):
               fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
        #       # With php-cgi (or other tcp sockets):
        #       fastcgi_pass 127.0.0.1:9000;
        }
}

Muốn nginx đọc được file cấu hình bạn phải tạo một symbolic link đến sites-enabled

ln -s /etc/nginx/sites-available/admin.nhanhviec.com /etc/nginx/sites-enabled/
lets now restart both nginx and php7.2-fpm

sudo service nginx reload
sudo service php7.2-fpm restart
Now lets create a index.php file within the document root i.e. root /var/www/html;

touch /var/www/html/index.php
and put phpinfo() and save it.

now open http://localhost and you should see the screen with all php informaiton
