Getting Started
　　Before starting, it is recommended to install all the required packages and update the repository to the latest version.
　　First, update the system using the following command:
　　sudo apt-get update -y
　　sudo apt-get upgrade -y
　　Once the repository is updated, restart the system to apply all the updates.
　　Next, install all the required packages by running the following command:
　　sudo apt-get install wget nano curl git -y
　　Next, you can proceed to install LAMP server
Install LAMP Server
　　Chevereto runs on Apache web server, written in PHP language and uses MariaDB to store their data. So you will need to install LAMP (Apache, PHP, MariaDB) to your system. You can install LAMP server with required PHP libraries using the following command:
　　sudo apt-get install apache2 libapache2-mod-php7.0 mariadb-server mariadb-client php7.0 php7.0-mysql php7.0-dom php7.0-gd php7.0-mbstring php7.0-common bc php7.0-bcmath -y
　　Once all the packages are installed, restart Apache and MariaDB service and enable them to start on boot with the following command:
　　systemctl start apache2
　　systemctl enable apache2
　　systemctl start mysql
　　systemctl enable mysql
　　Next, you will need to change the date and Timezone setting in `php.ini` file. You can do this using the following command:
　　sudo nano /etc/php/7.0/cli/php.ini
　　Change the following line as per your Timezone:
date.timezone = Asia/Kolkata　　Save and close the file, when you are finished.
Configure MariaDB for Chevereto
　　By default, MariaDB is not secured. You can secure it with the following command:
　　mysql_secure_installation
　　This command will set the root password, remove anonymous user, disallow root login remotely and remove test database.
　　Answer all the questions as follows:
Set root password? [Y/n] n　　
Remove anonymous users? [Y/n] y
　　
Disallow root login remotely? [Y/n] y
　　
Remove test database and access to it? [Y/n] y
　　
Reload privilege tables now? [Y/n] y
　　Once the MariaDB is secured, you will need to create a database and user for Chevereto.
　　First, log in to the MariaDB shell with the following command:
　　mysql -u root -p
　　Enter your root password, then create a database for Chevereto with the following command:
　　MariaDB [(none)]>CREATE DATABASE cheveretodb DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
　　Next, create a user for Chevereto and grant privileges to the Chevereto database with the following command:

　　MariaDB [(none)]>GRANT ALL PRIVILEGES ON cheveretodb.* TO 'chevereto'@'localhost'>　　Next, flush the privileges with the following command:
　　MariaDB [(none)]>FLUSH PRIVILEGES;
　　Finally, exit from the MySQL shell with the following command:
　　MariaDB [(none)]>\q
