Redis is an in-memory data structure store, used as a database server, cache, and message broker. It supports data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps and streams.<\/p>\n
It also provides PHP module for communication between PHP script with Redis server. Redis is Written in C programming language.<\/p>\n
In this tutorial will help you with the installation of Redis server along with PHP Redis PHP extensions on a CentOS 7 server.Let us have a step by step instructions, how to implement it.<\/p>\n
Step 1 : Prerequisites<\/h3>\n
1. Login to your server using secured shell access with the root account.<\/p>\n
# ssh root@remote<\/pre>\n2. Redis packages are not available in our default Yum<\/strong> Repository, so that Install a EPEL\u00a0<\/strong> Reposistory on your server . To Enable this Repository, execute the following command shown below,<\/p>\n
[root@sms ~]# sudo yum install epel-release\r\n<\/pre>\nPackage epel-release-7-11.noarch already installed and latest version. This will be a end output message conveyed to you.<\/p>\n
Step\u00a0 2 : Install Redis Server<\/h3>\n
1. Now, we can utilize a Yum repository , to install a Redis on our server.<\/p>\n
[root@sms ~]# sudo yum install redis<\/pre>\n2. After a\u00a0 successful installation.start<\/strong> Redis service and enable<\/strong> to auto-start on system reboot.<\/p>\n
[root@sms ~]# sudo systemctl start redis<\/pre>\nEnable it and check,whether the Redis service is active in our server.<\/p>\n
[root@sms ~]# sudo systemctl enable redis\r\n\r\n Created symlink from \/etc\/systemd\/system\/multi-user.target.wants\/redis.service to \/usr\/lib\/systemd\/system\/redis.service.<\/pre>\nStep 3 : Install Redis PHP extension<\/h3>\n
1.\u00a0 Check\u00a0 PHP\u00a0 is\u00a0 installed on your system.<\/p>\n
[root@sms conf]# php --version\r\n\r\nPHP 7.1.23 (cli) (built: Oct 10 2018 12:11:12) ( NTS )\r\nCopyright (c) 1997-2018 The PHP Group\r\nZend Engine v3.1.0, Copyright (c) 1998-2018 Zend Technologies.<\/pre>\nIn my system, PHP version\u00a0 7.1\u00a0 is enabled.<\/p>\n
2.\u00a0\u00a0To enable Redis PHP extension on your CentOS server. Follow these commands below,<\/p>\n
# pecl install igbinary igbinary-devel redis<\/pre>\nIn many of the system shows an error,\u00a0-bash: pecl: command not found.\u00a0<\/strong>To solve this , download the important PHP – Modules to enable the pecl command.<\/p>\n
[root@sms ~]# yum install php-devel<\/pre>\n[root@sms ~]# yum install php-pear<\/pre>\nAfter installation of this PHP module, Pecl command is Enabled\u00a0 . Now , Use the pecl to do a Redis PHP extension.<\/p>\n
# pecl install igbinary igbinary-devel redis<\/pre>\n3. After\u00a0 executed\u00a0 a\u00a0 above command ,verify Redis PHP extension is enabled or not.<\/p>\n
[root@sms ~]# php -m | grep redis<\/pre>\nRedis server has been installed on your system along with the PHP extension.<\/p>\n
Step 4 : Configure Redis as a Cache Server<\/h3>\n
