-------- Recommendations -----------------------------------------------------
General recommendations:
    Run OPTIMIZE TABLE to defragment tables for better performance
    MySQL started within last 24 hours - recommendations may be inaccurate
    Reduce your overall MySQL memory footprint for system stability
    Adjust your join queries to always utilize indexes
Variables to adjust:
  *** MySQL's maximum memory usage is dangerously high ***
  *** Add RAM before increasing MySQL buffer variables ***
    query_cache_size (>= 8M)
    join_buffer_size (> 128.0K, or always use indexes with joins)


i have questions the configuration off the my.ini .... i search in internet and not searched the internet more not found a very enlightening stuff.... some indication for reading?

Hello :)

Ensure you let MySQL run for at least 24 hours before running a tuner to obtain accurate results.

Thank you.

Use of uninitialized value in addition (+) at /usr/bin/mysqltuner line 567 (#1)
    (W uninitialized) An undefined value was used as if it were already
    defined.  It was interpreted as a "" or a 0, but maybe it was a mistake.
    To suppress this warning assign a defined value to your variables.

    To help you figure out what was undefined, perl will try to tell you
    the name of the variable (if any) that was undefined.  In some cases
    it cannot do this, so it also tells you what operation you used the
    undefined value in.  Note, however, that perl optimizes your program
    anid the operation displayed in the warning may not necessarily appear
    literally in your program.  For example, "that $foo" is usually
    optimized into "that " . $foo, and the warning will refer to the
    concatenation (.) operator, even though there is no . in
    your program.

-------- Recommendations -----------------------------------------------------
General recommendations:
    Run OPTIMIZE TABLE to defragment tables for better performance
    Reduce or eliminate persistent connections to reduce connection usage
    Upgrade MySQL to version 4+ to utilize query caching
    Adjust your join queries to always utilize indexes
    Increase table_cache gradually to avoid file descriptor limits
    Your applications are not closing MySQL connections properly
Variables to adjust:
    max_connections (> 350)
    wait_timeout (< 180)
    interactive_timeout (< 180)
    join_buffer_size (> 128.0K, or always use indexes with joins)
    table_cache (> )
