MYSQL數據庫修改mysql數據庫字符集編碼
mysql版本：5.0.27
安裝mysql時,由于失誤導致mysql默認編碼為latin1,這樣導致中文支持不了,遂想修改mysql編碼為utf8.
步驟如下：
一、管理工具-->服務-->停掉mysql服務
二、修改my.ini配置文件：
?
1.在[client]的port=3306的下面一行添加default-character-set=utf8
2.將[mysql]中的default-character-set=latin1中的latin1改為utf8
3. 將[mysqld]中的default-character-set=latin1中的latin1改為utf8
MYSQL數據庫三、重啟mysql服務
?
service mysqld restart
MYSQL數據庫四、進入mysql命令行,輸入以下命令檢查
?
MYSQL數據庫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 (0.00 sec)
MYSQL數據庫mysql> show variables like 'collation_%';
+----------------------+-----------------+
| Variable_name | Value |
+----------------------+-----------------+
| collation_connection | utf8_general_ci |
| collation_database | utf8_general_ci |
| collation_server | utf8_general_ci |
