Mysql lost privilegies after reboot - mysql

I use MYSQL 8.0.27 and Ubuntu. My problems are user's privileges. I can create and connect to database. It's ok. But when i reboot the machine, the user's privileges lost.
Example create user:
CREATE USER 'usuario'#'%' IDENTIFIED BY 'pass';
GRANT ALL PRIVILEGES ON bbdd.* TO 'usuario'#'%' WITH GRANT OPTION;
UPDATE user SET plugin='mysql_native_password' WHERE User='usuario';
If i show privilegies for usuario. I see that ok. But if i reboot my machine and again i show the privilegies mysql says There is no such grant defined for user 'usuario' on host '%'

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

Allow a user to connect to MySQL via MySQL Workbench

I'm trying to set up a connection to a database on my friend's laptop. I have his IP address and port number, but I can't connect to his machine and I think it's because he hasn't granted me permission. How does he grant me all privileges via the MySQL Workbench?
By below command-
GRANT ALL PRIVILEGES ON *.* TO your_name#'your_ip' identified by 'your_pass';
If you also want grant privileges, so that you can also assign rights then add with grant option at the end of sql.
from workbench gui you can do as per below-
go to server > user and privileges > add account
now you can choose options.

Set privilages to certain database for newly created user

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 connection from VM to host

Host:
Ubuntu 14.04
192.168.1.4
mysql database with: GRANT ALL PRIVILEGES ON . TO grails#'192.168.122.%' IDENTIFIED BY 'grails';
VM :
Centos 6.6
192.168.122.111
Problem:
Application (grails) can't see mysql database located on host machine.
url = "jdbc:mysql://192.168.122.11/grails?useUnicode=yes&characterEncoding=UTF-8"
I can
ping between 'machines'.
log with ssh from host to vm and vice versa
Try flushing the privileges
login as root and use MySQL; Database, something to do with the grant privilege
FLUSH PRIVILEGES;
remove the old user entry for that user and do a direct INSERT for the user with the domain into user table.
insert into user (....) values (....)
permission should be as per below-
GRANT ALL PRIVILEGES ON *.* TO grails#'192.168.122.%' IDENTIFIED BY 'grails';
or
GRANT ALL PRIVILEGES ON db.* TO grails#'192.168.122.%' IDENTIFIED BY 'grails';
If your permissions are ok, then go to 192.168.122.111 machine and try to connect db server from here by below command-
mysql -h 192.168.1.4 -ugrails -pgrails
If not able from here also then you need to check other things like iptables related firewall setting, port 3306 is open or not etc.

Connection to MySQL Server not working

I want to connect to my SQL Server on my remote server. I have installed MySQL on this server with apt-get and set up all necessary details. On the server everything works fine. When I want to connect with the MySQL Workbench, I cannot connect with any user at all.
I logged into MySQL in Ubuntu and created a new user first:
CREATE USER 'username'#'localhost' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON *.* TO 'username'#'localhost' WITH GRANT OPTION;
CREATE USER 'username'#'%' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON *.* TO 'username'#'%' WITH GRANT OPTION;
FLUSH PRIVILEGES;
I opened the my.cnf file:
port 3306
bind-address 127.0.0.01 (DO I NEED HERE MY REMOTE SERVER IP?)
service mysql restart
My questions would be:
1) why is the host 127.0.0.1 on my remote server?
2) In the workbench connection setup: which hostname is correct? my server IP or 127.0.0.1
3)I get the message: Failed to connect to MySQL. Access denied. So I think the user is the issue?
4) Do I need to change the cnf?
Thank you.
After you create the user and configure the right permission did you
FLUSH PRIVILEGES;
After you change your my.cnf did you restart Mysql?
Stop and Start from XAMPP Panel control
Change
bind address=127.0.0.1
to
bind-address=YOUR-SERVER-IP
