Linux查看并修改mysql字符集

1. 查看字符集：
mysql> show variables like 'collation_%';
+----------------------+-------------------+
| Variable_name | Value |
+----------------------+-------------------+
| collation_connection | utf8_general_ci |
| collation_database | latin1_swedish_ci |
| collation_server | latin1_swedish_ci |
+----------------------+-------------------+
3 rows in set (0.00 sec)

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

2.在[client]和[mysqld]下面添加
[client]
default-character-set=utf8
[mysqld]
character-set-server=utf8

3. 重启mysql服务，再次查看字符集
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 (0.00 sec)

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 | /data/app/mysql/share/charsets/ |
+--------------------------+---------------------------------+
8 rows in set (0.00 sec)
