mysql命令行修改字符编码
1 修改数据库字符编码
mysql> alter database mydb character set utf8 ;
2 创建数据库时,指定数据库的字符编码
mysql> create database mydb character set utf8 ;
3 查看mysql数据库的字符编码
mysql> show variables like ‘character%’; //查询当前mysql数据库的所有属性的字符编码
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/ |
4 修改mysql数据库的字符编码
修改字符编码必须要修改mysql的配置文件my.cnf,然后重启才能生效
通常需要修改my.cnf的如下几个地方:
【client】下面,加上default-character-set=utf8,或者character_set_client=utf8
【mysqld】下面,加上character_set_server = utf8 ;
因为以上配置,mysql默认是latin1,如果仅仅是通过命令行客户端,mysql重启之后就不起作用了。
如下是客户端命令行修改方式,不推荐使用
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/ |
