查看mysql的字符集
show variables where Variable_name like '%char%';
实际操作与输出信息如下：
mysql> show variables where Variable_name like '%char%';
+--------------------------+--------------------------------+
| Variable_name | Value |
+--------------------------+--------------------------------+
| character_set_client | utf8 |
| character_set_connection | latin1 |
| character_set_database | utf8mb4 |
| character_set_filesystem | binary |
| character_set_results | latin1 |
| character_set_server | utf8mb4 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql-8.0/charsets/ |
+--------------------------+--------------------------------+

修改mysql的字符集
mysql> set character_set_connection=utf8;
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> set character_set_database=utf8;
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> set character_set_results=utf8;
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> set character_set_server=utf8;
Query OK, 0 rows affected, 1 warning (0.00 sec)
再次查看mysql的字符集
mysql> show variables where Variable_name like '%char%';
+--------------------------+--------------------------------+
| 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 |
