关于mysql导入数据中文乱码问题解析

================mysql5.7改编码为utf8=========

网上很多都是直接改/etc/mysql/my.cnf文件配置

但是有些mysql5.7在改了/etc/mysql/my.cnf后不能正常启动

另一种方法：修改 /etc/mysql/mysql.conf.d/mysqld.cnf

#cd /etc/mysql/mysql.conf.d

#vim mysqld.cnf

末尾加入

character-set-server=utf8

collation-server=utf8_general_ci

skip-character-set-client-handshake

重启mysql:

#cd /etc/init.d/
#service mysql restart

mysql -u root -p

检查：

show variables like 'character%';

| Variable_name            | Value                      |

+--------------------------+----------------------------+

| character_set_client     | utf8                       |

| character_set_connection | utf8                       |

| character_set_database   | utf8                       |

| character_set_filesystem | binary                     |

| character_set_results    | utf8                       |

| character_set_server     | utf8                       |

| character_set_system     | utf8                       |

| character_sets_dir       | /usr/share/mysql/charsets/ |

完成

只有新创建的库才支持utf8。
