Redis is an in-memory, encrypted data store that is frequently used for caching, message brokering, and enhancing application speed. Installing and turning on Redis on CentOS and Ubuntu systems is described in this guide.<\/p>\n
Installing Redis on CentOS or Ubuntu gives you a high-performance, in-memory database that accelerates web applications, supports caching, session management, and message <\/a>queuing, while offering scalability and persistence for modern development needs.<\/p>\n You should see active (running) in the output, confirming that Redis is up and running.<\/li>\n Expected output:<\/p>\n This confirms that<\/a> Redis is responding to commands.<\/li>\n<\/ol>\n Look for active (running) to confirm the service is operational.<\/li>\n<\/ol>\n Expected output:<\/p>\n A PONG response confirms <\/a>Redis is working and ready for use.<\/li>\n<\/ol>\n You have successfully installed Redis on both CentOS and Ubuntu systems. With Redis up and running, you can now use its high-speed in-memory capabilities to enhance application performance, implement caching, manage sessions efficiently, and scale your applications seamlessly.<\/p>\n Need to update your system\u2019s host configurations?

\nBefore installing any new software, it\u2019s important to update your system\u2019s package index to guarantee you have the latest versions of dependencies and security patches.<\/p>\nsudo yum update -y<\/pre>\n<\/li>\n
\nInstall Redis from CentOS\u2019s default repository. This will also install any required dependencies automatically.<\/p>\nsudo yum install redis -y<\/pre>\n<\/li>\n
\nEnable Redis to start automatically at boot and start the service immediately:<\/p>\nsudo systemctl enable redis\r\nsudo systemctl start redis<\/pre>\n<\/li>\n
\nCheck if Redis is running correctly with the following command:<\/p>\nsudo systemctl status redis<\/pre>\n
\nConnect to Redis using the command-line interface and send a ping to verify connectivity:<\/p>\nredis-cli\r\nping<\/pre>\n

\nUpdate your package index to ensure you\u2019re installing the latest available version of Redis:<\/p>\nsudo apt update<\/pre>\n<\/li>\n
\nInstall Redis server using Ubuntu\u2019s package manager:<\/p>\nsudo apt install redis-server -y<\/pre>\n<\/li>\n
\nMake Redis start automatically on boot and start the service immediately:<\/p>\nsudo systemctl enable redis-server\r\nsudo systemctl start redis-server<\/pre>\n<\/li>\n
\nVerify that Redis is running properly:<\/p>\nsudo systemctl status redis-server<\/pre>\n
