Do NOT run the command

sudo apt-get install gcc g++

This is not needed.

Add to the Apache php.ini and not the CLI php.ini

If you add the statement to the PHP.INI for CLI – Command Line Interface -, then W3C Totalt Cache ” Node Auto Discovery:” is not able to locate the ElastiCache servers. You need to add the statement to the “apache2 php.ini” file. By following this process:

The Google PageSpeed Apache module at the time of writing only supports Memcached.

You should remove the old general Memcache if already installed on your server.
