How to Install and Use PHP Composer on CentOS 7

 sudo yum install php-cli php-zip wget unzip

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"

HASH="$(wget -q -O - https://composer.github.io/installer.sig)"

php -r "if (hash_file('SHA384', 'composer-setup.php') === '$HASH') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"

sudo php composer-setup.php --install-dir=/usr/local/bin --filename=composer

composer

The file GeoLite2-Country.mmdb does not exist or is not readable laravel

 Composer

From the command line run:

$ composer require torann/geoip

Laravel

Once installed you need to register the service provider with the application. Open up config/app.php and find the providers key.

'providers' => [

    \Torann\GeoIP\GeoIPServiceProvider::class,

]

This package also comes with an optional facade, which provides an easy way to call the the class. Open up config/app.php and find the aliases key.

'aliases' => [

    'GeoIP' => \Torann\GeoIP\Facades\GeoIP::class,

];

Publish the configurations

Run this on the command line from the root of your project:

php artisan vendor:publish --provider="Torann\GeoIP\GeoIPServiceProvider" --tag=config

A configuration file will be publish to config/geoip.php.

Configuration

Quick breakdown of the two main options in the configuration file. To find out more simple open the config/geoip.php file.

Service Configuration

To simplify and keep things clean, all third party composer packages, that are needed for a service, are installed separately.

For further configuration options checkout the services page.

Caching Configuration

GeoIP uses Laravel's default caching to store queried IP locations. This is done to reduce the number of calls made to the selected service, as some of them are rate limited.

Options:

• all all location are cached
• some cache only the requesting user
• none caching is completely disable
