PhpRedis cache backend

Get PhpRedis

You can download this library at:

https://github.com/phpredis/phpredis

This is a PHP extension.

Default behavior is to connect via tcp://localhost:6379, but you might want to connect differently.

Use the Sentinel high availability mode

Redis can provide a master/slave mode with sentinels server monitoring them. More information about setting it : https://redis.io/topics/sentinel.

This mode needs the following settings:

Modify the host as follow:

// Sentinels instances list with hostname:port format.
$settings['redis.connection']['host']      = ['1.2.3.4:5000','1.2.3.5:5000','1.2.3.6:5000'];

Add the new instance setting:

// Redis instance name.
$settings['redis.connection']['instance']  = 'instance_name';

Connect via UNIX socket

Just add these lines to your settings.php file:

$settings['redis.connection']['host'] = '/tmp/redis.sock'; // Your Redis socket
$settings['redis.connection']['port'] = 0; // For socket connections the port must be 0

Don't forget to change the path depending on your operating system and Redis server configuration.

Connect to a remote host and database

See README.md file.

For this particular implementation, host settings are overridden by the UNIX socket parameter.
