Install Redis Server and PHP-Redis on Debian or Ubuntu System Rumi, April 20, 2018 you can install the phpredis extension from the Ubuntu respositories. First, if you don’t have it installed already, let’s install Redis: sudo apt-get install redis-server After we get Redis installed (and/or verified that it was installed), we can install the PHP module for Redis: sudo apt-get install php5-redis After the module is done installing, you will want to restart your webserver and/or process manager (php-fpm, spawncgi, et cetera). Once you’ve restarted, you can check phpinfo() for a new section labeled Redis. On Ubuntu 14.x System, you may try: Install Redis 2.8.9 sudo apt-add-repository ppa:chris-lea/redis-server sudo apt-get update sudo apt-get install redis-server Remove Redis 2.8.9 sudo apt-get purge--auto-remove redis-server Administrations Configurations (Linux) DebianRedisUbuntu
