I have a database to work with. There is phpMyAdmin and it works good but I want to use an external database manager. I use the same login account what PhP script uses, still query browser doesnt see a database.
Anyone can know why?
I would guess that with phpMyAdmin, you are accessing MySQL from the WebServer that has IP address 1.0.0.1.
Then, from the external DB manager, you are accessing from IP address 1.0.0.2.
MySQL handles authentication and authorization using IP address (among other things) to authorize. So it's probably the case that you don't have all permissions for 1.0.0.2 in your MySQL database.
Your account is probably limited to 'localhost' only, try adding 'user'#'remote-ip' aswell.
For example:
GRANT ALL ON db.* TO 'jsmith'#'office.example.com' IDENTIFIED BY 'password';
FLUSH PRIVILEGES;

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 am very frustrated that I am trying this from over 5 days.
I need to create database on my PC that has to be visible for all other PCs in the same LAN.
I tried with XAMPP - Apache + MySQL - no result even after reading all articles from first 2 pages of Google and watching many youtube clips.
Now I am trying with MySQL Server 8.0 on my PC. I tried again all of Google first pages stuff without result. How can I do that?
I know that this has been asked many times here but there is no complex solution at all.
Does anybody of you have tutorial that is tested nowadays and it is working?
you should provide more details like the error message you get when connecting to the remote mysql server, anyway, to allow remote access, here is a checklist you need to go through:
grant permission, mysql by default only allow access from localhost(127.0.0.1), to allow other ip access:
// replace root for the username, '123456' for the password
grant all privileges on . to 'root'#'%' identified by '123456';
flush privileges;
check your server firewall settings to allow your mysql through port 3306(default)
others:
for linux server I think you also need to comment out "bind address" in your mysql config file;
some other issues for example your mysql client autodetect the wrong timezone, you may need to manually set it;
check your inbound rule on your client pc;
etc.
my suggestion for you, don't just google around blindly, think about it logically first, sometimes there is no direct answer
The problem was in connection String.
static final String USERNAME="[username]";
static final String PASSWORD="[password]";
static final String CONN_STRING="jdbc:mysql://[ip-address]:[port]/[database-name]";
So as LIU YUE suggested I just granted access for this username. The problem was that my other computer has a different name.
I just exported my tables from one web host to another (AWS).
Thinking everything would go smoothly (yeah right), well, everything that can go wrong has gone wrong.
I get this error when trying to query my database (which I didn't get before):
SQLSTATE[HY000] [1130] Host '<my ip address>' is not allowed to connect to this MySQL server
This is the same error from this post:
Host 'xxx.xx.xxx.xxx' is not allowed to connect to this MySQL server
The solution in that post seems to revolve around having an administrative user. I am developing a chat application so every user needs to access the server (so I'm sure it's a bad idea to give them all administrative privileges).
The answer by Pascal in that link says, If you are using mysql for a client/server application, prefer a subnet address. but I honestly don't understand what he means by that. And because of the amount of solutions, I'm not exactly sure which one I should follow based on my case.
How do I resolve this?
MySQL has security tables that determine who is allowed to connect and from what host IP address.
Here's a good article on how to do it:
http://www.cyberciti.biz/tips/how-do-i-enable-remote-access-to-mysql-database-server.html
If you have a lot of connections, consider setting up a server to accept the connections and talk to the sql server. The easiest approach to this is to set up a REST interface and use a web server. Web servers are usually also highly optimized and relatively bug free.
In a similar architecture on AWS, I use nginx happily.
Make sure you have bind-address=YOUR-SERVER-IP in my.cnf and make sure you have a user hd1#172.31.39.86 or hd1#%, the latter being a MySQL wildcard on the MySQL server. More information here. You may also need to grant access to port 3306 (the default MySQL port) on the security groups section of the AWS console.
// IN YOUR MYSQL WORKBENCH You Have to Execute below query
CREATE USER 'root'#'1.2.1.5(Your Application Server IP)' IDENTIFIED BY 'pass';
GRANT ALL PRIVILEGES ON *.* TO 'root'#'10.200.1.54' WITH GRANT OPTION;
AFTER CREATING YOU CAN VIEW USING BELOW QUERY
SELECT * FROM mysql.user WHERE User = 'root';
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.
I recently moved a few websites of mine from one hosting to another, but I decided to keep databases on the old hosting.
I did all the steps:
whitelisted new server's IP
changed all dbcon config ''localhost'' to old server IP
even changed outdated ''mysql_connect'' with mysqli
Still I cannot establish db connection at all!
How do I troubleshoot this? I have bno idea where else to look!
There might be some issues with PHP in the new hosting!
In PHP settings, the dropdown menu of ''Select PHP version" has only WARNING:Alternatives and ERROR:User options. Shouldn't there be PHP versions???
You may have to look at the MySQL user connections from within MySQL.
Here is what you do:
SELECT user,host FROM mysql.user;
This will reveal where each MySQL user can connection from.
If a user has host='%', then that user can connect from anywhere.
If a user has host='10.20.30.%', then that user can connect from '10.20.30.%' netblock only.
Let's take the latter case: a specific netblock.
Suppose your new servers are on netblock 20.30.40.%. You may have to go to each user and change the netblock in mysql.user.
EXAMPLE: For the user myuser.'10.20.30.%', and you want to change myuser to access MySQL from netblock 20.30.40.%, you would login to the DB server, connect to mysql as root#localhost, and execute this:
UPDATE mysql.user SET host='20.30.40.%' WHERE host='10.20.30.%';
FLUSH PRIVILEGES;
This will update every user's host column with the new netblock.
You could always use the GRANT command instead of hacking it like I just suggested.
If you cannot change mysql.user in either way, you may have to ask the DB Host provider to do that for you.
Give it a Try !!!
