Redis

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

In the upper right corner of this screen you will find information about the version of the Redis server and the port in use.

• 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, both local and network clients can connect to Redis. Otherwise, only local clients can connect (using the Unix socket /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

Connect using a UNIX socket (recommended)

// Connecting to Redis server on localhost$redis = new Redis();
$redis->connect('/Applications/MAMP/tmp/redis.sock');
// Check whether server is running or notecho 'Redis is running: ' . $redis->ping() . '<br>';
// Set the value of a key$key = 'product';$redis->set($key, 'MAMP PRO');
// Get the value of a keyecho '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 upif ($redis->exists([$key, 'list']) === 2) {  $redis->del($key);  $redis->del('list');}

Connect via network

// Connecting to Redis server on localhost$redis = new Redis();
$redis->connect('127.0.0.1', 6379);
// Check whether server is running or notecho 'Redis is running: ' . $redis->ping() . '<br>';
// Set the value of a key$key = 'product';$redis->set($key, 'MAMP PRO');
// Get the value of a keyecho '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 upif ($redis->exists([$key, 'list']) === 2) {  $redis->del($key);  $redis->del('list');}
