cat /var/log/mysqld.log | grep password

• 登录MySQL

mysql -u root -p

• 修改初始化密码（密码一定要大小写字母+数字+符号，如：Aa-123456789）

ALTER USER 'root'@'localhost' IDENTIFIED BY 'yourpassword';

• 远程设置

use mysql;
update user set host='%' where user='root';

• 允许任何主机访问数据库

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'WITH GRANT OPTION;
FLUSH PRIVILEGES;

• 允许myuser用户使用mypassword密码从任何主机连接到mysql服务器

GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%'IDENTIFIED BY 'mypassword' WITH GRANT OPTION;

GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.1.3'IDENTIFIED BY 'mypassword' WITH GRANT OPTION;

报错备注

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

解决：/etc/my.cnf 下[mysqld]后添加 skip-grant-tables

ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement

解决：刷新权限：flush privileges;
