mysql-导入数据库乱码问题

Posted 2021-02-03 格桑梅朵儿

查看字符集设置

mysql> show variables like ‘collation_%‘;
+----------------------+-------------------+
| Variable_name        | Value             |
+----------------------+-------------------+
| collation_connection | latin1_swedish_ci |
| collation_database   | utf8_general_ci   |
| collation_server     | utf8_general_ci   |
+----------------------+-------------------+
3 rows in set (0.00 sec)

mysql> show variables like ‘character_set_%‘;
+--------------------------+--------+
| Variable_name            | Value  |
+--------------------------+--------+
| character_set_client     | latin1 |
| character_set_connection | latin1 |
| character_set_database   | utf8   |
| character_set_filesystem | binary |
| character_set_results    | latin1 |
| character_set_server     | utf8   |
| character_set_system     | utf8   |
| character_sets_dir       |        |
+--------------------------+--------+
8 rows in set (0.00 sec)

 

通过mysql命令修改：（临时生效）

mysql> set character_set_client=utf8;
Query OK, 0 rows affected (0.00 sec)

mysql> set character_set_connection=utf8;
Query OK, 0 rows affected (0.00 sec)

mysql> set character_set_database=utf8;
Query OK, 0 rows affected (0.00 sec)

mysql> set character_set_results=utf8;
Query OK, 0 rows affected (0.00 sec)

mysql> set character_set_server=utf8;
Query OK, 0 rows affected (0.00 sec)

mysql> set character_set_system=utf8;
Query OK, 0 rows affected (0.01 sec)

mysql> set collation_connection=utf8;
Query OK, 0 rows affected (0.01 sec)

mysql> set collation_database=utf8;
Query OK, 0 rows affected (0.01 sec)

mysql> set collation_server=utf8;
Query OK, 0 rows affected (0.01 sec)

设置完成之后查看如下所示：

mysql> show variables like ‘character_set_%‘;
+--------------------------+----------------------------+
| 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/ |
+--------------------------+----------------------------+
8 rows in set (0.03 sec)
mysql> show variables like ‘collation_%‘;
+----------------------+-----------------+
| Variable_name         | Value            |
+----------------------+-----------------+
| collation_connection | utf8_general_ci |
| collation_database    | utf8_general_ci |
| collation_server      | utf8_general_ci |
+----------------------+-----------------+
3 rows in set (0.04 sec)

再次导入数据库，就不是乱码。
