I installed an instance of MySQL 5.1. The service runs fine when I log on as Administrator. But I am unable to run the instance using a local user account. The instance runs in 'localhost'. I get Error 5: Access Denied when I try to start the service from the local account. Should I elevate privileges to run the service? How do I do it? I tried to Run As Admin and it still doesn't work.
See MySQL docs: you need to CREATE USER and GRANT permissions specifically to the user#localhost.

I have an azure app service, using the latest wordpress image from docker hub. The screenshot for the azure app service:
Then in the azure app service -> application setting, I added the following key/value pairs which will be used to connect Azure database for mysql:
WORDPRESS_DB_HOST
WORDPRESS_DB_NAME
WORDPRESS_DB_PASSSWORD
WORDPRESS_DB_USER
screenshot:
Inside my Azure database for mysql, I have enabled public access / allow public access from any azure service / also add my client ip and this ip range 0.0.0.0 - 255.255.255.255. I can access it from my client and create the database which will be used by azure app service. Screenshot like below:
in server parameters, I also turn off the require_secure_transport setting:
At last, I tried to launch the site, but it throws the error "Error establishing a database connection", screenshot below:
I'm new to wordpress / docker, and don't know how to fix this issue. I also reviewed some videos / docs, and didn't see any other configuration differences. Could you please guide me how to fix this issue? Thanks very much.
You received this error message.
Warning: mysqli_real_connect(): (HY000/1045)>: Access denied for user 'ivan'#'52.xx.xxx.xx' (using password: YES)
It means MySQL received, processed, and rejected your WordPress instance's attempt to connect. So you know the hostname is right and your cloud provider's firewall settings allow your WordPress instance to exchange network data with your MySQL instance.
What's wrong?
MySQL's user name / account name setup has a quirk. An account name can look like 'ivan'#'localhost' or 'ivan'#'%' (or even something like 'ivan'#'192.0.22.33').
The first of those only allows login from localhost (or via tunneling via ssh). The second allows login from '%', meaning any host. You need the second one for your WordPress instance to get access to MySQL.
When you're logged in to MySQL from your machine, do this.
SELECT host, user FROM mysql.user WHERE user='ivan';
You should see two rows, like these
host user
---- ---
% ivan
localhost ivan
It's possible the account with '%' as the host is missing. If so that means you need to create another MySQL account and give it access to your database. Do that like this.
CREATE USER 'ivan'#'%' IDENTIFIED BY 'your_password';
FLUSH PRIVILEGES;
Next, make sure the user account you just created -- the one your WordPress software will use to connect to MySQL -- has access to your database.
GRANT ALL PRIVILEGES ON wordpress.* TO 'ivan'#'%';
FLUSH PRIVILEGES;
If you still get the error message, it's possible the password on your 'ivan'#'%' account doesn't match what you put into your WordPress configuration. You can change it with
ALTER USER 'ivan'#'%' IDENTIFIED BY 'your_password';
FLUSH PRIVILEGES;
If it still gives the same error message, it's possible that your cloud vendor requires TLS to connect to MySQL. You may want to consult their support team about that.
(This is a common stumbling block setting up new WordPress instances.)
ok just to keep and make things clear. all IPs can connect to the DB but are you actually authorized to read/write date in the DB?
I.E. this might be a permission/privilege issue.
I suggest double checking user privileges and determine who can do what on your DB
Best Regards. :-)
I think I've seen a variety of similar posts on this topic, but am still unable to resolve my issue, so I figured I'd post with my specifics.
I have an Amazon AWS Linux EC2 instance running Tomcat7 web server. On the same machine I am also running a MySQL5 server, but I am unable to get the Tomcat app to talk to the MySQL database.
My Java app on tomcat tries to connect to MySQL by reading from a properties file:
jdbc.mysql.host.path=jdbc:mysql://localhost/
jdbc.mysql.schema=prod
jdbc.mysql.username=root
jdbc.mysql.password=<password>
I am accessing the app from another system via web browser, but when the app tries to connect to the database I get the following error in catalina.out:
java.sql.SQLException: Access denied for user 'root'#'localhost' (using password: YES)
I'm pretty sure the issue has to do with permissions and communication between Tomcat and MySQL, because I've written a simple java program utilizing the same code to read the same properties file, and the connection is made successfully.
Here are some things I have attempted to remedy the issue:
change the owner of the properties file (currently owned by 'Tomcat')
ensured that user 'root' has been granted all privileges in MySQL
ensured that port 3306 (MySQL default port) is accessible by my test server
updated iptables made various modifications to /etc/my.cnf file
(tried to bind ip, but that didn't work)
I have a hunch that the issue may be related to the fact that I am trying to access the MySQL database using user 'root'. Even though I'm accessing it via localhost, the system may not support this because MySQL treats this as access from a separate host and (maybe?) root access from other hosts isn't allowed?
Any suggestions on things to try would be greatly appreciated...
I believe the issue was a combination of things.
Here are some items to consider that ultimately fixed it for me:
- making sure you were accessing the correct app via browser (I was using ROOT app, but trying to connect to another one)
- making sure a user exists in MySQL using 'Create User ....'
- making sure all privileges are granted on the database in question, for some reason granting all privileges on . wasn't working for me
I tried to transfer a website from one VPS to another using WHM Transfer Tool. Everything went fine except that I got this Warning in the end:
The system failed to grant privileges on the database “galssess_snapshot” to the user “galssess_info” because of an error: The following is not a valid MySQL privilege: SUPER
Any idea how to fix it?
Is there a way to grand this user SUPER privilege via cPanel or WHM?
Login your cpanel with galssess user and update the permission of galssess_snapshot databases through cPanel >> Databases >> MySQL Databases
I have seen a lot of posts that claim they are running an RDS instance of MySql in which they cannot connect to, but I am not running RDS.
I used my EC2 insance to host my wordpress blog which was installed using the Web Platform Installer.
This setup the wordpress schema and data that I needed and I have been running it for a couple years.
I want to be able to access this database remotely instead of only logging into my server.
I have checked and have the following users
root
wpadmin
I have also verified that the port specified in the mysql config is the standard 3306 and I have setup an Inbound Firewall rule to allow 3306 through.
When I try to connect from MySql Workbench, I get the following error message:
Number 3 Is particularly one that I do not know how to check, but I do know that MySql is running and that it is running on 3306. Additionally, I know I am using the correct password.
When I try to connect, the prompt looks like this. Do I need to do something to grant Mysql user permissions or anything?
Based on your GRANT information, you have at least the problem of root user only having access privileges from localhost. You would need to create a root#% user (or a more specific host/IP instead of % if you have a reliable address). That would allow external access so long as your EC2 security group also allow access on port 3306 (either globally or to a more restrictive IP address or IP range).
Of course the security implication here is that you are opening up access to MySQL that you might not want to make more accessbile to potential attackers. For this reason, I would recommend you access your DB via SSH tunnel, which is supported by MySQL workbench. This will in essence allow you to shell into the host your your access key and then access as root#localhost.
It seems that the web server is preventing me to change permissions to the user. It does not allow me to GRANT ALL ON foo.* TO bar#'202.54.10.20' IDENTIFIED BY 'PASSWORD'; and returns an error message of access denied for the username that I'm using.
It also appears that the folder etc in the file manager is empty whereas in the given link below, it shows that the bind address can be edited in the my.cnf inside etc folder.
How do I allow my mysql database to be accessible remotely by any computer?
http://www.cyberciti.biz/tips/how-do-i-enable-remote-access-to-mysql-database-server.html
The bind option in my.cnf is not that problem (since you can connect, the MySQL server is just not letting you in), and judging from the screenshot, you don't seem to have the permissions to edit that file anyways.
Most likely, your request is not coming from 202.54.10.20, or you have mistyped username/password. If the web application runs on the same machine as the MySQL server, connections will come from somewhere in the 127.0.0.0/8 range.
Look at the connection string in your web application:
If it is a public IP address, check username/password and originating IP.
If it starts with 127., GRANT to your local address.
If it is localhost, you're connecting via Unix socket instead of TCP. This is a good thing, and you can simply GRANT to localhost.
To issue this command:
GRANT ALL ON foo.* TO bar#'202.54.10.20' IDENTIFIED BY 'PASSWORD';
You MUST connect to the database first. So if you don't have permissions to remotely access database, you should go to the database server host and login locally, using root#localhost.
I just found out that there is an option which basically do the same thing as what I wanted it to be doing. There is an option for the user to enable remote database access to its clients.
