退出MySQL，去修改配置文件，修改完重启MySQL，再登陆，之前建的库还是不识别中文的，重新创建的才识别。
mysql配置中文：
1.修改mysql的配置文件 /etc/my.cnf，写入以下中文配置信息
[mysqld]
character-set-server=utf8
collation-server=utf8_general_ci
log-error=/var/log/mysqld.log
[client]
default-character-set=utf8
[mysql]
default-character-set=utf8
2.修改完配置文件，需要重启mysql，使得生效
systemctl restart mariadb
