基于utf8mb4比utf8多了种编码，能更好的支持emoji表情(http://dev.mysql.com/doc/refman/5.5/en/charset-unicode-utf8mb4.html)，所以我想让自己的mysql服务器默认使用utf8mb4编码。
于是就得到了配置文件 D:dbMySQLData5.6my.ini(并不是D:dbMySQLServer5.6my-default.ini)
[client] no-beep port=3306 [mysql] [mysqld] port=3306 datadir=D:/db/MySQL/Data5.6/Data character-set-client-handshake = FALSE character-set-server=utf8mb4 collation-server = utf8mb4_general_ci init_connect='set names utf8mb4' default-storage-engine=INNODB sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION" log-output=FILE general-log=0 general_log_file="TIANXIAOKU.log" slow-query-log=1 slow_query_log_file="TIANXIAOKU-slow.log" long_query_time=10 log-error="TIANXIAOKU.err" server-id=1 max_connections=151 query_cache_size=0 table_open_cache=2000 tmp_table_size=48M thread_cache_size=10 myisam_max_sort_file_size=100G myisam_sort_buffer_size=87M key_buffer_size=8M read_buffer_size=64K read_rnd_buffer_size=256K sort_buffer_size=256K innodb_additional_mem_pool_size=7M innodb_flush_log_at_trx_commit=1 innodb_log_buffer_size=4M innodb_buffer_pool_size=280M innodb_log_file_size=48M innodb_thread_concurrency=17 innodb_autoextend_increment=64 innodb_buffer_pool_instances=8 innodb_concurrency_tickets=5000 innodb_old_blocks_time=1000 innodb_open_files=300 innodb_stats_on_metadata=0 innodb_file_per_table=1 innodb_checksum_algorithm=0 back_log=80 flush_time=0 join_buffer_size=256K max_allowed_packet=4M max_connect_errors=100 open_files_limit=4161 query_cache_type=0 sort_buffer_size=256K table_definition_cache=1400 binlog_row_event_max_size=8K sync_master_info=10000 sync_relay_log=10000 sync_relay_log_info=10000
其中最主要的是以下几句：
character-set-client-handshake = FALSE # 设置客户端使用服务端配置的编码，忽略客户端编码的配置
character-set-server=utf8mb4 # 设置服务端编码
collation-server = utf8mb4_general_ci # 设置服务端排序规则
init_connect='set names utf8mb4'
还有个需要注意的就是：
1. default-storage-engine=INNODB 默认的数据存储引擎
2. sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION" 规则越严格，意味着操作时受到的限制越多！

再贡献一个windows上的phpstudy中mysql下的my.ini(D:softphpStudyMySQLmy.ini)配置：
