Error: php_network_getaddresses getaddrinfo failed redis

What's Causing This Error

When Redis fails to resolve the hostname of the Redis server, it throws the error 'php_network_getaddresses getaddrinfo failed redis'. This can happen due to various reasons such as incorrect configuration of the Redis server IP address or hostname, network connectivity issues, or DNS resolution problems. The error generally occurs in PHP applications using the Redis extension written in C programming language.

Solution - Here's How To Resolve It

To fix the error 'php_network_getaddresses getaddrinfo failed redis', you can implement the following solutions:

  1. Verify Redis Server IP Address or Hostname: Ensure that the IP address or hostname specified in the Redis server configuration file is correct. You can also use the ping command on the Redis server to check for reachability from the client machine.
  2. Check Network Connectivity: Verify that there are no network connectivity issues between the client machine and the Redis server. Use the ping command to check for any packet loss or network latency.
  3. Check DNS Resolution: If you are using a hostname to connect to the Redis server, ensure that the hostname can be resolved to an IP address. Use the nslookup command on the client machine to check if the hostname can be resolved to an IP address.
  4. Use IP Address Instead of Hostname: If DNS resolution is causing issues, try using the IP address of the Redis server instead of the hostname in the Redis configuration file.

By implementing these solutions, you should be able to establish a connection to the Redis server from your PHP application without encountering the 'php_network_getaddresses getaddrinfo failed redis' error.
