Thanks for your work.

Use of uninitialized value in addition (+) at /data/www/mysqltuner.pl line 2487 (#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.

    Reduce your overall MySQL memory footprint for system stability
    Dedicate this server to your database for highest performance.
    When making adjustments, make tmp_table_size/max_heap_table_size equal
    Reduce your SELECT DISTINCT queries which have no LIMIT clause
Variables to adjust:
  *** MySQL's maximum memory usage is dangerously high ***
  *** Add RAM before increasing MySQL buffer variables ***
    query_cache_size (=0)
    query_cache_type (=0)
    query_cache_limit (> 0B, or use smaller result sets)
    tmp_table_size (> 128M)
    max_heap_table_size (> 128M)

query cache have been deprecated.

In MySQL 8.0.11, several deprecated features related to account management have been removed, such as use of the GRANT statement to modify nonprivilege characteristics of user accounts, the NO_AUTO_CREATE_USER SQL mode, the PASSWORD() function, and the old_passwords system variable.

    Control warning line(s) into /usr/local/mysql/data/mysql-error.log file
    Reduce your overall MySQL memory footprint for system stability
    Dedicate this server to your database for highest performance.
    Adjust your join queries to always utilize indexes
    When making adjustments, make tmp_table_size/max_heap_table_size equal
    Reduce your SELECT DISTINCT queries which have no LIMIT clause
    Increase table_open_cache gradually to avoid file descriptor limits
    Read this before increasing table_open_cache over 64: http://bit.ly/1mi7c4C
    This is MyISAM only table_cache scalability problem, InnoDB not affected.
    See more details here: https://bugs.mysql.com/bug.php?id=49177
    This bug already fixed in MySQL 5.7.9 and newer MySQL versions.
    Beware that open_files_limit (100000) variable
    should be greater than table_open_cache (1024)
Variables to adjust:
  *** MySQL's maximum memory usage is dangerously high ***
  *** Add RAM before increasing MySQL buffer variables ***
    join_buffer_size (> 16.0M, or always use indexes with JOINs)
    tmp_table_size (> 128M)
    max_heap_table_size (> 128M)
    table_open_cache (> 1024)
