Setup Linux Server with Nginx, PHP and Mysql

Seting up Components

First, we need to update our local package index to make sure we have a fresh list of the available packages. Then we can install the necessary components:

sudo apt-get update
sudo apt-get install nginx php5-fpm php5-cli php5-mcrypt git

This will install Nginx as our web server along with the necessary PHP tools. We also install git because the composer tool, the dependency manager for PHP, will use it to pull down packages.

If you want to configure PHP then you can edit php.ini file and change configuration settings for that execute following statements

sudo vim /etc/php5/fpm/php.ini

Configuring Nginx Server root directory and default document

The next item that we should address is the web server. This will involve following two steps.

First create the folder where your website will be hosted(root directory)

sudo mkdir -p /var/www/vhosts/example.com

Now we need to set /var/www/vhosts/example.com as root directory of Nginx web server for that we need to edit default Nginx Configuration file located at /etc/nginx/sites-available/default.

sudo nano /etc/nginx/sites-available/default

Default Configuration file server { listen 80 default_server; listen [::]:80 default_server ipv6only=on;

    root /usr/share/nginx/html;
    index index.html index.htm;

    server_name localhost;

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

Now we need to

For thatc just change the Nginx default configuration file to following file.

server {
    listen 80 default_server;
    listen [::]:80 default_server ipv6only=on;

    root /var/www/vhosts/example.com;
    index index.php index.html index.htm;

    server_name <Static IP Address or Domain Name>;

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

Setup Nginx to execute PHP scripts

For this again we need to open Nginx Default Configuration file and add following block into it right before closing of server block

location ~ \.php$ {
    try_files $uri /index.php =404;
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    fastcgi_pass unix:/var/run/php5-fpm.sock;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi_params;
}

After saving finally configuration file should look like this

server {
    listen 80 default_server;
    listen [::]:80 default_server ipv6only=on;

    root /var/www/vhosts/example.com;
    index index.php index.html index.htm;

    server_name <Static IP Address or Domain Name>;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location ~ \.php$ {
        try_files $uri /index.php =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }
}

After saving the configuration file we just need to restart Nginx

sudo service nginx restart

Setting up Composer

Composer is the most popular dependency manager for php projects and to setup composer we just need to execute following commands.

cd ~
curl -sS https://getcomposer.org/installer | php
sudo mv composer.phar /usr/local/bin/composer

Installing up Mysql

Mysql is the most common and popular database server used with PHP and to setup mysql databse you just need to execute

sudo apt-get update
sudo apt-get install mysql-server

This will prompt you for mysql root(admin) password too.

Updating and verifying Mysql Server

sudo mysql_secure_installation

Above command will prompt you and can be used to remove default created users and test databases that came right out of the box along with mysql installation.

to test mysql installation try executing 

service mysql status

If above command gives an error then just start mysql service with command

sudo service mysql start

Securing Mysql

Database is the crucial part of a website which needs to be secure for that you may consider following guidelines(optional)

Renaming root username

Root is the database administrator account which has all the privileges so it make sense to chage root credentials after installation(especially username).

for that execute following command

mysql -u root -p 
<Enter mysql Password>
mysql> rename user 'root'@'localhost' to '<new_username>'@'localhost';

Creating New user with limited Database Access and limited privileges

mysql -u root -p
<Enter mysql password>
mysql> GRANT SELECT,UPDATE,DELETE ON <database_name>.* TO '<new_user>'@'localhost';

After completing all the steps mentioned above your webserver will be ready with Nginx, PHP, Composer and Mysql

But In some cases you might get Mysql Connection Exception saying mysql driver not found for that just execute following command

sudo apt-get install php5-mysql

And you are done...
