The error "memcached does not start" can be caused by various factors. One possible cause is incorrect configuration settings, such as specifying an invalid port or file path. Another possible cause is insufficient permissions for the user running the memcached service to access certain files or directories. A third possible cause could be conflicts with other software or services running on the same machine, which could cause port or resource allocation issues.
To resolve the "memcached does not start" error, there are several potential solutions depending on the underlying cause. One solution is to check and modify the configuration settings to ensure that they are correct and consistent with the environment in which memcached is running. Another solution is to ensure that the user running the memcached service has sufficient permissions to access any necessary files or directories.
Another solution involves checking for conflicts with other software or services running on the same machine. This may involve temporarily disabling or modifying the settings of other software or services that may be using the same ports or resources as memcached. Finally, another solution may involve reinstalling or upgrading memcached to address any known bugs or compatibility issues.
