Can't set query-cache-size

[Haw Loeung]

Hi,

It seems there's issues with the query-cache settting. In config.yaml, it says it's of type 'int:

| query-cache-size can
| query-cache-size:
| default: 0
| type: int

But when I try set it to query-cache-size=8388608, it produces an invalid config:

| /usr/bin/mysqladmin: connect to server at 'localhost' failed
| error: 'Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)'
| Check that mysqld is running and that the socket: '/var/run/mysqld/mysqld.sock' exists!
| Unknown suffix '.' used for variable 'query_cache_size' (value '8388608.0')
