Set privilages to certain database for newly created user - mysql

I have foo_bar_test database existing on my mysql server on host 127.0.0.1.
But there's no user that can access it but root, and I don't want to use root user anywhere in my code. So I created new user, fb_test, and granted him privileges for this database:
create user fb_test#'127.0.0.1' identified by password 'some_password';
grant all on 'foo_bar_test.*' to fb_test#'127.0.0.1';
flush privileges;
Ok, that should work, but when I log in as this user, I don't have any database available!
What's wrong?
I checked it using show grants for fb_test#'127.0.0.1', but it shows some strange results:
grant usage on *.* to fb_test#'127.0.0.1' identified by password '*another_password_dont_know_which_one'
How do I solve this?

you have an error in grant statement. Use the query:
grant all on 'foo_bar_test'.* to fb_test#'127.0.0.1';
In fact your grant command results an error which I think you ignored.

mysql: database specific user permission delegation with grant option and wildcard

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.

How to grant all privileges to root user in MySQL 8.0

Tried
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'#'%' IDENTIFIED BY 'root' WITH GRANT OPTION;
Getting
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use near 'IDENTIFIED BY 'root' WITH GRANT OPTION' at line 1.
Note: The same is working when tried in previous versions.
Also tried
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'#'%' WITH GRANT OPTION;
Getting
ERROR 1410 (42000): You are not allowed to create a user with GRANT
MySQL (8.0.11.0) username/password is root/root.
Starting with MySQL 8 you no longer can (implicitly) create a user using the GRANT command. Use CREATE USER instead, followed by the GRANT statement:
mysql> CREATE USER 'root'#'%' IDENTIFIED BY 'PASSWORD';
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'#'%' WITH GRANT OPTION;
mysql> FLUSH PRIVILEGES;
Caution about the security risks about WITH GRANT OPTION, see:
Grant all privileges on database
I see a lot of (wrong) answers, it is just as simple as this:
USE mysql;
CREATE USER 'user'#'localhost' IDENTIFIED BY 'P#ssW0rd';
GRANT ALL ON *.* TO 'user'#'localhost';
FLUSH PRIVILEGES;
Note: instead of a self-created user you can use root to connect to the database. However, using the default root account to let an application connect to the database is not the preferred way. Alternative privileges can be applied as follows (be careful and remember the least-privilege principle):
-- Grant user permissions to all tables in my_database from localhost --
GRANT ALL ON my_database.* TO 'user'#'localhost';
-- Grant user permissions to my_table in my_database from localhost --
GRANT ALL ON my_database.my_table TO 'user'#'localhost';
-- Grant user permissions to all tables and databases from all hosts --
GRANT ALL ON *.* TO 'user'#'*';
If you would somehow run into the following error:
ERROR 1130 (HY000): Host ‘1.2.3.4’ is not allowed to connect to this
MySQL server
You need add/change the following two lines in /etc/mysql/my.cnf and restart mysql:
bind-address = 0.0.0.0
skip-networking
You could run into the following error, which is a bit confusing:
ERROR 1410 (42000): You are not allowed to create a user with GRANT
This means that either the user does not exist at all OR that the user#host combination does not exist. You can easily check for this with the following command:
SELECT host, user FROM user
1) This worked for me. First, create a new user. Example: User foo with password bar
> mysql> CREATE USER 'foo'#'localhost' IDENTIFIED WITH mysql_native_password BY 'bar';
2) Replace the below code with a username with 'foo'.
> mysql> GRANT ALL PRIVILEGES ON database_name.* TO'foo'#'localhost';
Note: database_name is the database that you want to have privileges, . means all on all
3) Login as user foo
mysql> mysql -u foo -p
Password: bar
4) Make sure your initial connection from Sequelize is set to foo with pw bar.
Just my 2 cents on the subject. I was having the exact same issue with trying to connect from MySQL Workbench. I'm running a bitnami-mysql virtual machine to set up a local sandbox for development.
Bitnami's tutorial said to run the 'Grant All Privileges' command:
/opt/bitnami/mysql/bin/mysql -u root -p -e "grant all privileges on *.* to 'root'#'%' identified by 'PASSWORD' with grant option";
This was clearly not working, I finally got it to work using Mike Lischke's answer.
What I think happened was that the root#% user had the wrong credentials associated to it. So if you've tried to modify the user's privileges and with no luck try:
Dropping the user.
Create the user again.
Make sure you have the correct binding on your MySQL config file.
In my case I've commented the line out since it's just for a sandbox environment.
1. Dropping the user.
From Mysql Console:
List Users (helpful to see all your users):
select user, host from mysql.user;
Drop Desired User:
drop user '{{ username }}'#'%';
2. Create the user again.
Create User and Grant Permissions:
CREATE USER '{{ username }}'#'%' IDENTIFIED BY '{{ password }}';
GRANT ALL PRIVILEGES ON *.* TO '{{ username }}'#'%' WITH GRANT OPTION;
Run this command:
FLUSH PRIVILEGES;
3. Make sure you have the correct binding on your MySQL config file.
Locate your MySQL config file (additional notes at the end). If you want to have MySQL listen for connections on more than one network find the following line on the config file:
bind-address=127.0.0.1
and comment it using a '#':
#bind-address=127.0.0.1
For production environments you might want to use limit the network access (additional notes at the end).
Then restart your MySQL service.
Hope this helps someone having the same issue!
Binding: If you want to know more about this I suggest looking at the following
solution How to bind MySQL server to more than one IP address. It
basically says you can leave MySQL open and limit connections by using
a firewall, or natively if you have MySQL version 8.0.13 and above.
MySQL Config File The file could have different locations depending on your
Linux distribution and installation. On my system it was located at
'/etc/my.cnf'. Here are other suggested locations:
/etc/mysql/mysql.conf.d
/etc/mysql/my.cnf
You can also search for the config locations as shown in this website:
How to find locations of MySQL config files.
For those who've been confused by CREATE USER 'root'#'localhost' when you already have a root account on the server machine, keep in mind that your 'root'#'localhost' and 'root'#'your_remote_ip' are two different users (same user name, yet different scope) in mysql server. Hence, creating a new user with your_remote_ip postfix will actually create a new valid root user that you can use to access the mysql server from a remote machine.
For example, if you're using root to connect to your mysql server from a remote machine whose IP is 10.154.10.241 and you want to set a password for the remote root account which is 'Abcdef123!##', here are steps you would want to follow:
On your mysql server machine, do mysql -u root -p, then enter your password for root to login.
Once in mysql> session, do this to create root user for the remote scope:
mysql> CREATE USER 'root'#'10.154.10.241' IDENTIFIED BY 'Abcdef123!##';
After the Query OK message, do this to grant the newly created root user all privileges:
mysql> GRANT ALL ON *.* TO 'root'#'10.154.10.241';
And then:
FLUSH PRIVILEGES;
Restart the mysqld service:
sudo service mysqld restart
Confirm that the server has successfully restarted:
sudo service mysqld status
If the steps above were executed without any error, you can now access to the mysql server from a remote machine using root.
My Specs:
mysql --version
mysql Ver 8.0.16 for Linux on x86_64 (MySQL Community Server - GPL)
What worked for me:
mysql> CREATE USER 'username'#'localhost' IDENTIFIED BY 'desired_password';
mysql> GRANT ALL PRIVILEGES ON db_name.* TO 'username'#'localhost' WITH GRANT OPTION;
Response in both queries:
Query OK, O rows affected (0.10 sec*)
N.B: I created a database (db_name) earlier and was creating a user credential with all privileges granted to all tables in the DB in place of using the default root user which I read somewhere is a best practice.
The specified user just doesn't exist on your MySQL (so, MySQL is trying to create it with GRANT as it did before version 8, but fails with the limitations, introduced in this version).
MySQL's pretty dumb at this point, so if you have 'root'#'localhost' and trying to grant privileges to 'root'#'%' it treats them as different users, rather than generalized notion for root user on any host, including localhost.
The error message is also misleading.
So, if you're getting the error message, check your existing users with something like this
SELECT CONCAT("'", user, "'#'", host, "'") FROM mysql.user;
and then create missing user (as Mike advised) or adjust your GRANT command to the actual exisiting user specificaion.
You will get this error
ERROR 1410 (42000): You are not allowed to create a user with GRANT
If you are trying to run a GRANT on a user that doesn't exist!
Therefore, first run this to make sure the user you use in your GRANT matches exactly to what you have:
select User, Host from user;
In particular pay attention whether the user you created is at localhost but the one you are trying to grant to is %
Copy this and use it at once:
CREATE USER 'username'#'localhost' IDENTIFIED BY 'password';
GRANT ALL ON *.* TO 'username'#'localhost';
FLUSH PRIVILEGES;
Instead of using single lines of code such as:
CREATE USER 'username'#'localhost' IDENTIFIED BY 'password';
Then:
GRANT ALL ON *.* TO 'username'#'localhost';
Then:
FLUSH PRIVILEGES;
Many thanks #Nebulastic
If you want to only allow remote IP using following command
CREATE USER 'user_test'#'113.yy.xx.94' IDENTIFIED BY 'YOUR_PWD';
GRANT ALL ON *.* TO 'user_test'#'113.yy.xx.94';
FLUSH PRIVILEGES;
This worked for me:
mysql> FLUSH PRIVILEGES
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'#'%'WITH GRANT OPTION;
mysql> FLUSH PRIVILEGES
Check out your username and domain is the same as created before. Mysql select account by the two colums in user table.If it is different, mysql may think you want to create a new account by grant,which is not supported after 8.0 version.
My Specs:
mysql --version
mysql Ver 8.0.19 for Linux on x86_64 (MySQL Community Server - GPL)
What worked for me:
mysql> USE mysql;
mysql> UPDATE User SET Host='%' WHERE User='root' AND Host='localhost';
this commands work for me:
1-login to mysql and see all users
sudo mysql -u root
select user, host from mysql.user;
2-delete old user
drop user root#localhost;
3-create new user
CREATE USER 'root'#'localhost' IDENTIFIED BY 'mypassword'
4-add all privileges to it:
GRANT ALL ON *.* TO 'root'#'localhost'
ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password
BY 'mypassword';
5-finally flush privileges
FLUSH PRIVILEGES;
in select statement, changing 'user'#'%' to 'user'#'localhost' solved my problem
In my case I wanted to do something similar, I followed some steps from here but the best way was as #nebulasic mentioned:
USE mysql;
CREATE USER 'user'#'localhost' IDENTIFIED BY 'P#ssW0rd';
GRANT ALL ON *.* TO 'user'#'localhost';
FLUSH PRIVILEGES;
After this I encountered an error while trying to query the database or connect with SQLTools from VSCode.
Client does not support authentication protocol requested by server; consider upgrading MySQL client
Running this query will fix the problem:
ALTER USER 'user'#'localhost' IDENTIFIED WITH mysql_native_password BY 'Your_newP#s$w0Rd';
I also want to mention that these steps are ok to work in a local environment, when doing something in production is recommended to allocate each user to each database with generated password accordingly and different other security measures if necessary.
Well, I just had the same problem. Even if route had '%' could not connect remotely. Now, having a look at my.ini file (config file in windows) the bind-address statement was missed.
So... I putted this bind-address = * after [mysqld] and restarted the service. Now it works!
1. grant privileges
mysql> GRANT ALL PRIVILEGES ON . TO 'root'#'%'WITH GRANT OPTION;
mysql> FLUSH PRIVILEGES
2. check user table:
mysql> use mysql
mysql> select host,user from user
3.Modify the configuration file
mysql default bind ip:127.0.0.1, if we want to remote visit services,just delete config
#Modify the configuration file
vi /usr/local/etc/my.cnf
#Comment out the ip-address option
[mysqld]
# Only allow connections from localhost
#bind-address = 127.0.0.1
4.finally restart the services
brew services restart mysql
Try this, i had the same issue and i tried few options, but the below worked.
GRANT ALL ON . TO 'root'#'%';

ubuntu 22.04.1
Mysql Ver 8.0.31-0
My root had no GRANT privileges so I could not grant new users any previligies.
Solution was to Drop current root user and create new one using 'mysql_native_password'.
Commands as follows
Login to mysql with as root
mysql> DROP USER 'root'#'localhost' IDENTIFIED BY 'PASSWORD' FROM mysql.user;
mysql> CREATE USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'#'locahost' WITH GRANT OPTION;
mysql> FLUSH PRIVILEGES;
This may work:
grant all on dbtest.* to 'dbuser'#'%' identified by 'mysql_password';
I had this same issue, which led me here. In particular, for local development, I wanted to be able to do mysql -u root -p without sudo. I don't want to create a new user. I want to use root from a local PHP web app.
The error message is misleading, as there was nothing wrong with the default 'root'#'%' user privileges.
Instead, as several people mentioned in the other answers, the solution was simply to set bind-address=0.0.0.0 instead of bind-address=127.0.0.1 in my /etc/mysql/mysql.conf.d/mysqld.cnf config. No changes were otherwise required.
I had the same problem on CentOS and this worked for me (version: 8.0.11):
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'#'%'
Stary mysql with sudo
sudo mysql

MySQL "mysql there is no such grant defined for user"

This error happened when I granted all privileges to a new root account I just created.
Steps to produce the problem:
CREATE USER 'root'#'localhost';
GRANT ALL PRIVILEGES ON *.* TO 'root'#'localhost' WITH GRANT OPTION;
FLUSH PRIVILEGES;
SHOW GRANTS for 'root'#'localhost';
After "show grants" I got the error "mysql there is no such grant defined for user 'root' on host 'localhost'". There were no errors after executing the first three commands. The new user was created successfully.
How do I solve this problem?
More info:
I'm running MySQL 5.7 on my MacOS laptop(OSX 10.10.5).
There is nothing wrong with your posted code but as guess try with wildcard symbol % like
SHOW GRANTS for 'root'#'%';
(OR)
As an alternative, login with your created user 'root'#'localhost' and just use SHOW GRANTS. See Documentation
I don't think mysql allows you to create another root account. So the create causes an error.
CREATE USER 'root'#'localhost';
ERROR 1396 (HY000): Operation CREATE USER failed for 'root'#'localhost'
You should check for the existing root account in the user table and you'll find the wildcard to be '%' which should mean you do not need to create a localhost root user.
select * from user where user = 'root';
Asking to show grants on root localhost should work, and does work for me.
show grants for 'root'#'localhost';
Step-1:
sudo mysql -u root -p
Step-2:
REVOKE ALL PRIVILEGES, GRANT OPTION FROM 'user name'#'localhost';
Ex.-
REVOKE ALL PRIVILEGES, GRANT OPTION FROM 'admin'#'localhost';
Step-3:
FLUSH PRIVILEGES;
I think it will work.

Why won't my mysql grant privilege to user?

Oddly enough it seems my mysql will not allow creating a user with access to a specific database. Using MySQL Workbench:
CREATE USER 'testUser'#'localhost' IDENTIFIED BY 'thepasswordhere';
GRANT ALL PRIVILEGES ON testDatabaseName TO 'testUser'#'localhost' WITH GRANT OPTION;
SHOW GRANTS;
I see nothing mentioning granted privileges for the created user. This explains why I get mysqli::mysqli(): (28000/1045): Access denied for user 'testUser'
What step am I missing?? Update: Even when I mistype the username I still get a success with 0 rows affected: GRANT ALL PRIVILEGES ON testDatabaseName TO 'testkUser'#'%' WITH GRANT OPTION; so I think something's seriously wrong with my local mysql. Any ideas on a fix?
CREATE USER 'testUser'#'localhost' IDENTIFIED BY 'thepasswordhere';
GRANT ALL PRIVILEGES ON testDatabaseName.* TO 'testUser'#'localhost' WITH GRANT OPTION;
SELECT sql_grants FROM common_schema.sql_show_grants;
What changed? I simply added a .* after database name. It's necessary so the user has access to all tables inside the database.
Also for the latest mysql, I believe you need to put user password when using grant.
So do as follows:
CREATE USER 'testUser'#'localhost' IDENTIFIED BY 'thepasswordhere';
GRANT ALL PRIVILEGES ON testDatabaseName.* TO testUser#localhost IDENTIFIED BY 'pass' WITH GRANT OPTION;
FLUSH PRIVILEGES;
SELECT sql_grants FROM common_schema.sql_show_grants;
As mentioned by Michael in the question comments:
SHOW GRANTS FOR 'testUser'#'localhost';... otherwise, SHOW GRANTS;
shows your privileges -- the ones associated with the account that is
currently logged in.

Grant privileges to user in MySQL

From the control panel of my website I have created a new MySQL(5) database Test and a new user admin with password 123. I have tried assigning privileges to the user admin using:
GRANT ALL PRIVILEGES ON *.* TO 'admin'#'localhost'
or
GRANT ALL PRIVILEGES ON *.* TO 'admin'#'Test'
I keep getting the following error:
#1045 - Access denied for user 'admin'#'%' (using password: YES)
I need the following privileges for the user admin:
CREATE, ALTER, DELETE, INSERT, SELECT, UPDATE, LOCK TABLES
How do I make that in a query from phpMyAdmin?
I guess you are trying to change privileges of 'admin'#''%' being logged in as that user. This is strange.
You can display which user you are logged in as using
SELECT USER();
Then check grants that account already has:
SHOW GRANTS FOR 'admin'#''%';
We came to the conclusion you have
GRANT ALL PRIVILEGES ON `Test`.* TO 'admin'#'%'
That says you already have all privileges on all tables in database Test. You cannot further grant those privileges to other users, though (otherwise there would be WITH GRANT OPTION).
During the installation of MySQL, root user is always created. Use it to grant privileges to other accounts.
More info in manual:
2.10.2. Securing the Initial MySQL Accounts
6.3.2. Adding User Accounts
After run these statements try to execute FLUSH:
FLUSH PRIVILEGES;
From MYSQL Reference Manual :
(...) If you change the grant tables directly but forget to reload them, your changes have no effect until you restart the server. This may leave you wondering why your changes do not seem to make any difference!
To tell the server to reload the grant tables, perform a flush-privileges operation. (...)
Login as a root user then grant all privileges to admin user.
GRANT ALL PRIVILEGES ON `test`.* TO 'admin'#'localhost';
