Laravel has support out of the box for using Redis. However, by default it uses a Redis client written in PHP, which will always be a little slower than one written in C. If you're making heavy use of Redis, it may be worth using the phpiredis extension to squeeze a little more performance out of it.
I'm using PHP 7.0 on Ubuntu Zesty and I installed the dependencies with the following command:
$ sudo apt-get install libhiredis-dev php-redis php7.0-dev
Then I installed phpiredis as follows:
1git clone https://github.com/nrk/phpiredis.git && \2 cd phpiredis && \3 phpize && \4 ./configure --enable-phpiredis && \5 make && \6 sudo make install
Finally, I configured Redis to use phpiredis in the
redis section of
config/database.php for a Laravel app:
1 'redis' => [23 'cluster' => false,45 'default' => [6 'host' => env('REDIS_HOST', 'localhost'),7 'password' => env('REDIS_PASSWORD', null),8 'port' => env('REDIS_PORT', 6379),9 'database' => 0,10 'options' => [11 'connections' => [12 'tcp' => 'Predis\Connection\PhpiredisStreamConnection', // PHP streams13 'unix' => 'Predis\Connection\PhpiredisSocketConnection', // ext-socket14 ],15 ]16 ],17 ],
Now, I'm going to be honest - in a casual comparison I couldn't see much difference in terms of speed. I would probably only bother with setting this up on a site where high Redis performance was absolutely necessary. If you just want a quicker cache response it might make more sense to put Varnish in front of the site instead. However, in cases where Redis gets used heavily, it's probably worth doing.
