mysql增加新用户无法登陆解决方法
在使用mysql增加新用户之后,发现新增的用户无法登陆,一时束手无策,网上搜集整理了一下,晒出来和大家分享一下,希望可以帮助你们
今天安装openstack folsom版本,安装完mysql,为各个服务增加对应的数据库和用户后,发现无法使用新增的用户登陆mysql。我增加用户的方法如下:
mysql -uroot -p$MYSQL_PASS CREATE DATABASE nova;
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY '$MYSQL_PASS';
CREATE DATABASE glance;
GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' IDENTIFIED BY '$MYSQL_PASS';
CREATE DATABASE keystone;
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%'IDENTIFIED BY '$MYSQL_PASS';
CREATE DATABASE cinder;
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%'IDENTIFIED BY '$MYSQL_PASS';
CREATE DATABASE quantum;
GRANT ALL PRIVILEGES ON quantum.* TO 'quantum'@'%'IDENTIFIED BY '$MYSQL_PASS';
FLUSH PRIVILEGES;
EOF
但使用用户登陆失败:
root@controller:~# mysql -h localhost -ukeystone -ppassword
ERROR 1045 (28000): Access denied for user 'keystone'@'localhost' (using password: YES)
解决方法:
增加普通用户后,执行:
mysql> use mysql
mysql> delete from user where user='';
mysql> flush privileges;
意思是删除匿名用户。
OK,搞定,enjoy!
