今天安裝openstack folsom版本，安裝完mysql，為各個服務增加對應的數據庫和用戶后，發現 無法使用新增的用戶登陸mysql。我增加用戶的方法如下： mysql -uroot -p$MYSQL_PASS <<EOF CREATE DATABASE nova; GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY '$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 但使用用戶登陸失敗： root@controller:~# mysql -h localhost -ukeystone -ppassword ERROR 1045 (28000): Access denied for user 'keystone'@'localhost' (using password: YES) 解決方法： 增加普通用戶后，執行： mysql> use mysql mysql> delete from user where user=''; mysql> flush privileges; 意思是刪除匿名用戶。 OK，搞定，enjoy！
