-------- Recommendations ---------------------------------------------------------------------------
General recommendations:
    Control warning line(s) into /var/db/mysql/database.local.err file
    Dedicate this server to your database for highest performance.
    Reduce or eliminate persistent connections to reduce connection usage
    Configure your accounts with ip or subnets only, then update your configuration with skip-name-resolve=1
    Increase table_open_cache gradually to avoid file descriptor limits
    Read this before increasing table_open_cache over 64: http://bit.ly/1mi7c4C
    Beware that open_files_limit (108081) variable
    should be greater than table_open_cache (256)
    Performance should be activated for better diagnostics
    Consider installing Sys schema from https://github.com/mysql/mysql-sys
Variables to adjust:
    max_connections (> 151)
    wait_timeout (< 28800)
    interactive_timeout (< 28800)
    query_cache_size (=0)
    query_cache_type (=0)
    query_cache_size (> 16M)
    table_open_cache (> 256)
    performance_schema = ON enable PFS
    innodb_buffer_pool_size (>= 1G) if possible.
    innodb_log_file_size * innodb_log_files_in_group should be equals to 1/4 of buffer pool size (=64M) if possible.
    innodb_buffer_pool_instances (=1)
    innodb_log_buffer_size (>= 16M)

#innodb_data_home_dir = /var/db/mysql
#innodb_data_file_path = ibdata1:10M:autoextend
#innodb_log_group_home_dir = /var/db/mysql
