启动mysql后,以root登录mysql $mysql -u root -p >show variables like 'character%'; #执行编码显示 +--------------------------+----------------------------+ | Variable_name | Value | +--------------------------+----------------------------+ | character_set_client | latin1 | | character_set_connection | latin1 | | character_set_database | latin1 | | character_set_filesystem | binary | | character_set_results | latin1 | | character_set_server | latin1 | | character_set_system | utf8 | | character_sets_dir | /usr/share/mysql/charsets/ | +--------------------------+----------------------------+在某些时候,我们续要修改mysql默认数据库的编码,以保证某些迁移的程序可以正常显示,编辑my.cnf文件进行编码修改,windows可以直接用Mysql Server Instance Config Wizard 进行设置 在linux下修改3个my.cnf的1个/etc/mysql/my.cnf文件 找到客户端配置[client] 在下面添加 default-character-set=utf8 默认字符集为utf8 在找到[mysqld] 添加 default-character-set=utf8 默认字符集为utf8 init_connect='SET NAMES utf8' (设定连接mysql数据库时使用utf8编码,以让mysql数据库为utf8运行)修改好后,重新启动mysql 即可,查询一下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/ | +--------------------------+----------------------------+此方法用于标准mysql版本同样有效,对于/etc/my.cnf文件,需要从mysql/support-files的文件夹cp my-large.cnf一份到/etc/my.cnf |
