-------- Recommendations ---------------------------------------------------------------------------
General recommendations:
    /var/log/mysqld.log is > 32Mb, you should analyze why or implement a rotation log strategy such as logrotate!
    Control warning line(s) into /var/log/mysqld.log file
    Control error line(s) into /var/log/mysqld.log file
    Restrict Host for user@% to user@SpecificDNSorIp
    MySQL was started within the last 24 hours - recommendations may be inaccurate
    Configure your accounts with ip or subnets only, then update your configuration with skip-name-resolve=1
    Adjust your join queries to always utilize indexes
    Increase table_open_cache gradually to avoid file descriptor limits
    Read this before increasing table_open_cache over 64: http://bit.ly/1mi7c4C
    Read this before increasing for MariaDB https://mariadb.com/kb/en/library/optimizing-table_open_cache/
    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 (10000) variable
    should be greater than table_open_cache (2000)
    Optimize queries and/or use InnoDB to reduce lock wait
    Before changing innodb_log_file_size and/or innodb_log_files_in_group read this: http://bit.ly/2wgkDvS
Variables to adjust:
    query_cache_size (=0)
    query_cache_type (=0)
    join_buffer_size (> 12.0M, or always use indexes with JOINs)
    table_open_cache (> 2000)
    innodb_log_file_size should be (=128M) if possible, so InnoDB total log files size equals to 25% of buffer pool size.
