I want to create a new mysql user and database demo in my company. Here is the commands i input in the mysql.exe :
create user 'admin'#'localhost' identified by 'admin';
create database dem;
Everytime i have that response:
access denied for user ''#'localhost' to database.
Actually i refered to that similar question :
MySQL - Access denied for user
Can anyone help please ???
I would suggest creating the database first then you can create a user, and use the GRANT option to allow permissions to that user for whatever you find necessary. However, creating a user first then a database while it's able to "potentially" work, isn't the best practice with MySQL. So you want to effectively do the Steps as such:
Create Database
Create User
GRANT permissions
???
Profit
You have to GRANT access to admin for dem.
GRANT ALL PRIVILEGES ON *.* TO 'admin'#'%' WITH GRANT OPTION;
You may have to also GRANT the same for admin#localhost as well. IIRC if you ever logon remotely with admin you would inherit the base privileges unless otherwise GRANTed
You can find many answers HERE.

I switch to MySQL 8 recently; earlier I was using MySQL 5.7 in GCP. I know questions like this have already been asked, but I didn't have any luck. My question is, I want to create a new user just say 'user1' and grant all privileges to a user account on all databases.
The query I am using for user creation:
CREATE USER 'user-1'#'%' IDENTIFIED BY 'user_password';
For privileges:
GRANT ALL PRIVILEGES ON *.* TO 'user-1'#'%';
This privileges query used to work on MySQL 5.7, but when I try to run this query in MySQL 8, I get this error (I logged in as root user and MySQL is in GCP):
SQL Error (1045): Access denied for user 'root'#'%' (using password: YES)
I also tried to run this query one after another like this:
CREATE USER 'user-1'#'%' IDENTIFIED BY 'user_password';
GRANT ALL PRIVILEGES ON *.* TO 'user-1'#'%';
But still I get the same error. I came to know that in MySQL 8 localhost root user have all the privileges, but my server is in Google Cloud, so how can I grant all the privileges to the user I created?
When I run this query in the mysql-8 (I am using HeidiSQL to connect the DB and run query)
SELECT * FROM mysql.user;
I got this output:
In this there are two root users:
For one host is localhost/127.0.0.1 (With all the privilege).
For other host is % (Not have any privilege).
I think I logged in as a user with host-% because my server is in GCP, that's why I cannot give any privilege to the user that I have created. So is there any way to give full permission to the
root#%
so that I can give full permission to the other users, Because I don't think there is any way to log in as a root#localhost
The problem here is that you are trying to create a super user, which is not something supported in cloud SQL, as you can see in this documentation:
Cloud SQL does not support SUPER privileges, which means that GRANT ALL PRIVILEGES statements will not work. As an alternative, you can use GRANT ALL ON %.*.
This alternative mentioned could be enough to grant the permissions you expected.
I am trying to grant privileges to another user using phpmyadmin, I have access to the root user (cl43-flexfit) and have tried querying the following
GRANT ALL PRIVILEGES ON `cl43-flexfit`.* TO 'supuser'#'localhost';
But receive a response of:
Access denied for user 'cl43-flexfit'#'%' to database 'cl43-flexfit'
Although I use that database with the cl43-flexfit user frequently.
I have also looked at what the root users privileges are using SHOW GRANT
and was shown these:
GRANT USAGE ON *.* TO 'cl43-flexfit'#'%' IDENTIFIED BY PASSWORD 'password'
GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER, CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE, CREATE VIEW, SHOW VIEW, CREATE ROUTINE, ALTER ROUTINE, TRIGGER ON `cl43-flexfit`.* TO 'cl43-flexfit'#'%' WITH GRANT OPTION
and even when I try to add permissions to the user for every database (replacing cl43-flexfit.* with * .*) I get an error saying I do not have permission
Access denied for user 'cl43-flexfit'#'%' (using password: YES)
I have been in contact with my hosting service and they have said that everything is correct on their end.
I also do not have access to the privileges tab in PHPMyAdmin and therefore can not use the GUI, it must be done through written commands.
Thanks in advance and apologise if I have a lack of understanding
You cannot GRANT ALL unless you also hold all privileges, along with GRANT OPTION, which you do not.
You have to grant explictly, and list only the permissions that you have (and want to grant).
You can't grant anything ON *.* unless you globally hold the privilege you are trying to grant, on all objects, plus GRANT OPTION. Again, you don't have this.
USAGE means only that you are allowed to log in to the server, nothing more. This is a special case of ON *.* carrying no significant meaning, because merely logging into the server is associated with no particular object.
The hosting service is correct.
If you have other users, you can make only explicit grants of listed permissions, using the format shown in your own SHOW GRANTS output.
GRANT SELECT, INSERT, [more...], TRIGGER ON `cl43-flexfit`.* TO 'my-other-existing-user'#'%';
I want to have a non-root mysql user that can create another databases and users and grant access to that users to created databases. To do this as root I firstly created a user
CREATE USER asusi_admin#localhost IDENTIFIED BY '123';
Then I grant create user PRIVILEGE to this user
GRANT CREATE USER ON *.* TO 'asusi_admin'#localhost';
Then I grant all privileges to this user for the every database he creates
GRANT ALL PRIVILEGES ON `asusi\_%`.* TO 'asusi_admin'#'localhost WITH GRANT OPTION;
Now I'm flushing privileges
FLUSH PRIVILEGES;
Now I'm logging on to MySQL as newly created user asusi_admin and creating a new database
Now I'm creating a new database
CREATE DATABASE asusi_database;
Now I'm checking that I can use this database
USE asusi_database;
I can use this database, good
Now I'm creating a new user
CREATE USER 'asusi_user'#'localhost' IDENTIFIED '123';
Now I want to grant select privilege to the created user
GRANT select on `asusi_database`.* 'asusi_user'#'localhost'
And here I'm getting an error: 'Access denied for user 'asusi_admin'#'localhost' to database 'asusi_superdb'
Should I relogin as root and explicitly grant access to this database to a asusi_user
GRANT ALL PRIVILEGES ON `asusi_database`.* TO 'asusi_admin'#'localhost WITH GRANT OPTION;
and then relog in as asusi_admin and run the command again
GRANT select on `asusi_database`.* 'asusi_user'#'localhost'
this time it gives me no error and user asusi_user can read database asusi_database. Apparently MySQL wants me to explicitly grant access to the user asusi_admin for the every created database via root account. But I don't want to use the root account. I thought that after executing this command
GRANT ALL PRIVILEGES ON `asusi\_%`.* TO 'asusi_admin'#'localhost WITH GRANT OPTION;
user asusi_admin will be able to grant access to other users to the ecery database that stats with 'asusi_' prefix. May be I missed something or this behavior is designed to be that way?
It seems this is a confirmed bug, that was not fixed yet https://bugs.mysql.com/bug.php?id=75097, so nothing you can do right now with it.
yesterday I deployed a MySQL database image from the Azure marketplace. It is this one issued by Microsoft. I can connect with the user I specified in the Azure portal and was able to create an additional user for testing purposes and grant it all privileges on two different databases. However, if try to do the same today I get the infamous Error Code: 1044. Access denied for user 'admin'#'%' to database 'mysql'. I have read that some MySQL versions on Azure do not support user privilege handling, but I was already able to do it with this image version. I even verified that the created user had access to the specified databases and inserting/selecting data from it was also working. I have tried setting up a fresh database with a new testuser to no avail, as i received the same error. This is basically what I did:
CREATE USER 'user'#'%' IDENTIFIED BY 'pw';
GRANT INSERT ON db.* TO 'user'#'%' IDENTIFIED BY 'pw';
FLUSH PRIVILEGES;
After the user was created I also checked with SHOW GRANTS FOR 'user'#'%' for the given permissions and they were there. The admin user specified in the Azure portal also has grant_priv privileges. Can someone please help me to understand why all of a sudden it is not possible for me to grant even simple privileges to newly created users? It should be possible as this Blogpost from an Microsoft employee suggests. Clearly I am missing something as such a basic feature should be included.
How does one create a privileged user in MySQL( not root ) for the sole purpose of creating other users?
However, this user can only grant access to one database at a time.
Is it possible to give limited GRANT permissions to a user?
yes you can create mysql user and grant limited permissions using phpmyadmin
interface and also by command
use following command for creating user and grant permissions
CREATE USER 'monty'#'localhost' IDENTIFIED BY 'some_pass';
GRANT SELECT ON database.* TO 'user'#'localhost';
