The error message 'memcached is not installed' suggests that the Memcached service is not installed on the machine where it is expected to be running. The Memcached service is a popular in-memory caching solution that is often used to boost application performance by storing frequently accessed data in memory for faster retrieval.
This error can occur when attempting to use Memcached on a machine where it has not been installed or when the application configuration is pointing to an incorrect server location. Additionally, it can also occur if the Memcached service has been stopped or if there is a problem with the installation that prevents the service from starting.
To resolve this error, you need to ensure that the Memcached service is installed and properly configured. If Memcached is not already installed, you will need to install it using your operating system's package manager or by downloading and installing it manually from the Memcached website. Once installed, make sure that the Memcached service is running by checking its status and starting it if necessary.
If the Memcached service is already installed but still not working, check the application configuration file to ensure that it is pointing to the correct server location and port number. Additionally, check the log files for any errors that may be preventing the service from starting or running properly. If you are unable to troubleshoot the issue on your own, consider seeking help from a Memcached expert or consulting the Memcached documentation and community forums for further assistance.
