Installation of Redis

The first step is to install Redis on your CentOS system.

After installing Redis, you need to start the Redis service by running the following command:

sudo systemctl start redis

You can check if Redis is running by typing the command:

redis-cli ping

You should see a response of "PONG", which means Redis is running properly.

Installation of Redis Extension for PHP

Now that Redis is installed on your CentOS system, you can proceed to install the Redis extension for PHP. There are different ways to install this extension, but the most popular one is using pecl, a command-line tool that simplifies the installation process.

To install pecl, run the following commands:

sudo yum install php-pear

sudo yum install php-devel

Once pecl is installed, you can install the Redis extension by executing the following command:

sudo pecl install redis

After the installation is complete, you need to enable the extension by adding the following line to your php.ini file:

extension=redis.so

Finally, you need to restart the Apache web server to apply the changes by running the following command:

sudo systemctl restart httpd
