修改root默認密碼

grep 'temporary password' /var/log/mysqld.log
查看root密碼而後登錄
set global validate_password_policy=1;//0,1,2(密碼長度)
SET PASSWORD = PASSWORD('root');
另外一種修改密碼方法:
    use mysql;
    update user set authentication_string = password("root") where User = 'root';
複製代碼

容許root遠程登陸

//update user set host = ’%’ where user = ’root’;
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'password' WITH GRANT OPTION;//password爲本身設置密碼。
flush privileges;
複製代碼

改字符編碼機

//停數據庫
systemctl stop mysqld
//進入 my.cnf 文件，通常是在etc路徑下
vim /etc/my.cnf
//加入要修改的字符集 修改完:wq退出
在[mysqld]下追加：
character-set-server=utf8
在[mysql]下追加：
default-character-set=utf8
//重啓數據庫
