Redis is an open source (BSD licensed) in-memory data structure store used as a database, cache and message broker.

MAMP PRO - Settings - Server - Redis

In the upper right corner of this screen you will find information about which version of the Redis server is being used and which port is being used.

  • Use Redis server
    Check this box if you want the Redis server to start and stop automatically when the Start/Stop button in the toolbar is clicked. The Redis PHP extension is automatically included when this option is enabled.

  • Allow network access to Redis
    With this option enabled local and network clients can connect to Redis. Otherwise only local clients can connect (using the Unix socked “/Applications/MAMP/tmp/redis.sock”).

    • only from this Mac
      Only applications installed on this Mac can access Redis via network features.

    • from other computers
      Redis will answer any network request, even from computers on the Internet, depending on your network settings.

  • Maximum speed

    • Disable database compression and checksum
      Your data is kept in memory by the Redis server. The data is backed up automatically from time to time or manually to a file on disk. By default, the data is compressed and a CRC64 checksum is generated (for higher data integrity). If you enable the checkbox, the data is not compressed and the checksum is set to 0. When importing such a file, the content is not checked in combination with the checksum.

  • Log level:

    Select how much information should be written to the Redis log. The following options are available:

    Name Description
    Warning only very important/critical messages are logged
    Notice moderately verbose, what you want in production probably
    Verbose many rarely useful info, but not a mess like the debug level
    Debug a lot of information, useful for development/testing

  • Log file:
    The path to your Redis log file.

    • Choose…
      Here you can choose the directory and the file name. By default, this log file is located at “/Applications/MAMP/logs/redis_error.log”.

PHP Examples

// Connecting to Redis server on localhost
$redis = new Redis();
 
$redis->connect('/Applications/MAMP/tmp/redis.sock');
 
// Check whether server is running or not
echo 'Redis is running: ' . $redis->ping() . '<br>';
 
// Set the value of a key
$key = 'product';
$redis->set($key, 'MAMP PRO');
 
// Get the value of a key
echo 'Key "' . $key . '" has the value "' . $redis->get($key) . '"' . '<br>';
 
// Store data in redis list
$redis->lPush('list', 'MAMP PRO');
$redis->lPush('list', 'Apache');
$redis->lPush('list', 'MySQL');
$redis->lPush('list', 'Redis');
 
// Get the list data
$list = $redis->lRange('list', 0, 3);
echo '<br>';
echo 'Stored list:';
echo '<pre>';
print_r($list);
echo '</pre>';
 
// Clean up
if ($redis->exists([$key, 'list']) === 2) {
  $redis->del($key);
  $redis->del('list');
}

// Connecting to Redis server on localhost
$redis = new Redis();
 
$redis->connect('127.0.0.1', 6379);
 
// Check whether server is running or not
echo 'Redis is running: ' . $redis->ping() . '<br>';
 
// Set the value of a key
$key = 'product';
$redis->set($key, 'MAMP PRO');
 
// Get the value of a key
echo 'Key "' . $key . '" has the value "' . $redis->get($key) . '"' . '<br>';
 
// Store data in redis list
$redis->lPush('list', 'MAMP PRO');
$redis->lPush('list', 'Apache');
$redis->lPush('list', 'MySQL');
$redis->lPush('list', 'Redis');
 
// Get the list data
$list = $redis->lRange('list', 0, 3);
echo '<br>';
echo 'Stored list:';
echo '<pre>';
print_r($list);
echo '</pre>';
 
// Clean up
if ($redis->exists([$key, 'list']) === 2) {
  $redis->del($key);
  $redis->del('list');
}
