Error: cannot assign requested address redis

Solution

What's Causing This Error

The error 'cannot assign requested address redis' usually occurs when Redis is unable to bind to the specified IP address or port. This can happen due to various reasons, such as:

• The IP address or port that Redis is trying to bind to is already in use by another application.
• The specified IP address doesn't exist on the host machine.
• The operating system's network configuration doesn't allow Redis to bind to the specified IP address or port.

If any of these issues occur, Redis won't be able to start up and will throw the 'cannot assign requested address redis' error.

Solution - Here's How To Resolve It

To resolve the 'cannot assign requested address redis' error, you can try the following solutions:

• Check if the specified IP address or port is already in use by another application. If it is, free up the resource so that Redis can bind to it.
• Verify that the specified IP address exists on the host machine. You can do so by running the ifconfig or ip addr command on Linux machines, or the ipconfig command on Windows machines. If the IP address doesn't exist, either change the Redis configuration file to use an existing IP address or create the IP address on the server.
• Ensure that the operating system's network configuration allows Redis to bind to the specified IP address or port. Check for any firewall rules or network policies that might be blocking Redis from binding to the specified IP address or port. Adjust the network configuration accordingly to allow Redis to bind to the desired IP address and port.

By following these steps, you should be able to fix the 'cannot assign requested address redis' error and get Redis up and running successfully.
