• 依次设置编码格式

set character_set_client = utf8;
set character_set_connection = utf8;
set character_set_database = utf8;
set character_set_filesystem = utf8;
set character_set_results = utf8;
set character_set_server = utf8;
set collation_connection = utf8_general_ci;
set collation_database = utf8_general_ci;

• 设置my.cnf配置文件
