一、修改數據庫字符編碼mysql
mysql> alter database mydb character set utf8 ;sql
二、建立數據庫時,指定數據庫的字符編碼數據庫
mysql> create database mydb character set utf8 ;編碼
三、查看mysql數據庫的字符編碼命令行
mysql> show variables like 'character%'; //查詢當前mysql數據庫的全部屬性的字符編碼server
+--------------------------+----------------------------+
| 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 | /usr/share/mysql/charsets/ |

四、修改mysql數據庫的字符編碼字符編碼
修改字符編碼必需要修改mysql的配置文件my.cnf,而後重啓才能生效cli
一般須要修改my.cnf的以下幾個地方:配置
【client】下面,加上default-character-set=utf8,或者character_set_client=utf8
【mysqld】下面,加上character_set_server = utf8 ;
由於以上配置,mysql默認是latin1,若是僅僅是經過命令行客戶端,mysql重啓以後就不起做用了。
以下是客戶端命令行修改方式,不推薦使用
mysql> set character_set_client=utf8 ;
mysql> set character_set_connection=utf8 ;
mysql> set character_set_database=utf8 ;
mysql> set character_set_database=utf8 ;
mysql> set character_set_results=utf8 ;
mysql> set character_set_server=utf8 ;
mysql> set character_set_system=utf8 ;
mysql> 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/ |+--------------------------+----------------------------+8 rows in set (0.00 sec)
