[ERROR] COLLATION ‘utf8_unicode_ci‘ is not valid for CHARACTER SET ‘latin1‘
[ERROR] COLLATION 'utf8_unicode_ci' is not valid for CHARACTER SET 'latin1'
错误来源是:
跟着b站的谷粒商城项目做,前面的视频中设置了数据库的字符集编码,但是后面自己发现了MySQL容器重启报错,不停的在重启
查看log信息可以使用命令:docker logs 容器id
错误如下:
也就是说,前面我在
设置的如下字符集编码内容是有问题
[client]
default-character-set=utf8
[mysql]
default-character-set=utf8
[mysqld]
init_connect='SET collation_connection = utf8_unicode_ci' init_connect='SET NAMES utf8' character-set-server=utf8
collation-server=utf8_unicode_ci
skip-character-set-client-handshake
skip-name-resolve
删除my.cnf文件MySQL容器又可以正常启动
解决方法:
vi /mydata/mysql/conf/my.cnf
把my.cnf文件做出如下修改
[client]
default_character_set=utf8
[mysql]
default-character-set=utf8
[mysqld]
collation_server = utf8_general_ci
character_set_server = utf8
skip-character-set-client-handshake
skip-name-resolve
重启MySQL容器
docker restart mysql
进入容器内部查看
docker exec -it mysql /bin/bash
修改字符集编码成功,退出容器重启MySQL也不存在报错
默认MySQL5.7的字符集编码是:
show variables like 'character_set_%';
注意
docker安装完MySQL并run出容器后,建议请先修改完字符集编码后再新建mysql库-表-插数据
