I'm facing some issue when installation in MySQL-Server. I tried to change the root password several times but it does not work as I expected. Finally when I'm going to change the password It's shows like this kind of output. How can I resolve this problem. When I going to connect to the sql database using netbeans it's output shows this error.
Cannot establish a connection to jdbc:mysql://localhost:3306/mysql?zeroDateTimeBehavior=CONVERT_TO_NULL using com.mysql.cj.jdbc.Driver (Access denied for user 'root'#'localhost')
mysql > select user, authentication_string plugin from mysql.user;
I think that you have correct password, but NetBeans cannot connect to TCP port 3306 at all. As soon as JDBC driver cannot connect to unix socket, please try to bind MySQL Server to tcp port 3306.
I think that it will be enough to check your MySQL configuration and find "skip-networking" option and remove it.
Please check /etc/my.cnf.d directory and /etc/my.cnf file for this line, delete it and restart MySQL server.
If you need to change the root password, the easiest way is to run mysql_secure_installation script from root user.

Can anyone tell me why I got an alert with the access denied error?
I tried to create a mysql database and I confidently sure I entered the correct password for root yet I still got this error.
However, based on the mysql documentation for troubleshooting, my error specified that I did not enter the correct password which in fact I did not.
Mysql documentation
https://dev.mysql.com/doc/refman/5.5/en/problems-connecting.html
Also , I tried to run this command sudo mysql -u root -pand it also show me the same error.
P.S Because my reputation is too low, I can't attach the full image.
might be check you are currently connect with the correct password plugin, use the following Command,
SELECT user, authentication_string, plugin, host FROM mysql.user;
If your are login with root, check whether plugin is "mysql_native_password" if not, change as it is with the following command.
ALTER USER 'root'#'localhost IDENTIFIED WITH mysql_native_password BY 'Password#123'
You may get this error when your mysqld is configured to accept connection only from localhost.
In such case, you need to modify bind-address property in /etc/mysql/mysql.conf.d/mysqld.cnf. You can allow only your ip or from the whole internet(0.0.0.0).
Make sure to restart the mysql server.
sudo systemctl restart mysql.
That's not it. You also need to allow connection on port 3306 using commands like ufw or iptables.
I had this problem on Beekeeper and DBeaver. It was driving me INSANE. I literally copied the password and was testing the connections manually and it was working perfectly. Annoyingly this server was working perfectly with MySQL workbench on Windows before I migrated over to Fedora.
So I needed to set the "SSH" section so that it would log me in to the other device. That test connection worked perfectly. But STILL no success. "Password failure" an incredibly inaccurate error message...
Turns out after enabling the SSH connection I forgot to change the "Server host" variable from it's IP (192...) to 'localhost'. Now it works perfectly.
It Could be various things try this:
In main configuration username="root" password="YOUR_PASSWORD" As in no need to put the actual password, only copy "YOUR_PASSWORD"
If it still doesn´t work leave the database bank
Check that your IP address is added to the server permissions/security
Check that the DB is available and that public connection is allowed
If using Windows allow connections to the port 3306 on the Firewall Defender(control panel, security, firewall defender, advanced setting, add inbound rule, port, 3306, allow)
For anyone struggling with SSH tunnel. I found that sometimes 127.0.0.1 is not being translated back to localhost before privileges are being check.
Try setting up a grant for 127.0.0.1 with the following.
GRANT ALL PRIVILEGES ON *.* TO 'user'#`127.0.0.1`;
This did the trick for me.
Please enter these configurations in connection window
I have a strange issue on a web server (Windows Server 2012) with MySQL 5.7.16.
I can't connect anymore to mysql server, I don't know why.
If I type mysql -uroot -ppassword appear an error
ERROR 1130 <HY000>: Host '::1' is not allowed to connect to this MySQL server or
ERROR 1130 <HY000>: Host '127.0.0.1' is not allowed to connect to this MySQL server
I tried to use another user with all privileges and I've seen that in host there is only localhost (not 127.0.0.1 or ::1)
How can I login with root#localhost and not with root#127.0.0.1?
It's very frustrating...
Every account trying to use #127.0.0.1 or #::1 but there exist only localhost in host and I can't change it.
If I type mysql -uroot -ppassword I see
ERROR 1130 <HY000>: Host '127.0.0.1' is not allowed to connect to this MySQL server
Same if I type mysql -uroot -ppassword -h localhost or anything else
Ok i Fixed...
I've comment "skip_name_resolve" in my.ini and everything is back to work.. i really don't know why because this record was in my.ini also yesterday..last week.. last month..
The variable skip_name_resolve gives better performance because the server does not try to resolve the names of the connecting clients or look for them every time in the host name cache (even localhost is resolved/searched), but the manual states that config also limits the #localhost connections. The solution is to copy the #localhost users with #127.0.0.1, like this:
CREATE USER 'root'#'127.0.0.1' IDENTIFIED BY 'root-password';
CREATE USER 'root'#'::1' IDENTIFIED BY 'root-password';
FLUSH PRIVILEGES;
where ::1 is localhost for IPv6 addressing. This way we keep the root and local accounts limited to the local server. Using '%' open the potential clients to the world, and we don't want that. Disabling skip_name_resolve also requires the server having an accesible and fast DNS resolver to minimize latency.
I noted that I can connect with a local phpmyadmin even if the user has #localhost; this is because phpmyadmin connects thru a local unix socket, a special type of file used to communicate between processes, and does not need networking.
EDIT: As #Francisco R noted, the new root users also should have full access to all databases by issuing the following commands:
GRANT ALL PRIVILEGES ON *.* TO 'root'#'127.0.0.1'
GRANT ALL PRIVILEGES ON *.* TO 'root'#'::1'
FLUSH PRIVILEGES
I had the same message after a fresh installation with the no-install zip and solved it as follows. Perhaps this could have been a solution for your problem too:
Stop the MySQL server or service.
Open a Command Prompt window with administrative rights and go to the bin folder in the MySQL install directory.
Start MySQL with skip-grants-table and don't forget your config file:
mysqld --defaults-file=[filename] --skip-grant-tables
Open another Command Prompt window and go to the bin folder again.
Now you can login:
mysql -u root -p
Show the users with:
SELECT user, host FROM mysql.user;
Verify there is one 'root' with host 'localhost'.
Change the host:
UPDATE mysql.user SET host='%' WHERE user='root';
Exit the mysql program and close the Command Prompt window.
Type Ctrl-C in the other Command Prompt window to stop the server, then close the Command Prompt Window.
Start MySQL as you normally would and verify that you can login.
Make sure that when you created the user you have specified % as the hostname, otherwise the user will only be able to connect from the localhost.
I came here looking for a solution using Local by flywheel for wordpress development to the same problem, BUT, in a linux machine.
Just if someone faces the same problem, the solution listed here works.
Just comment skip_name_resolve in the file conf/mysql/my.cnf.hbs under the file tree created by Local
Thanks!
Looks that you need to modify your hosts file. C:\Windows\System32\Drivers\etc\hosts
just add the line and save it, (to be able to edit and save you may need to open it as administrator)
127.0.0.1 localhost
I have recently installed MySQL 5.7.16 on an iMac running El Capitan. I had a few minor hiccups initially because I forgot the root password but that has now been reset and I can now log into MySQL as root user using:
$ mysql -u root -p
However, when I try to connect to MySQL server as root using SequelPro, I get the message:
Unable to connect via the socket, or the request timed out.
Double-check that the socket path is correct and that you have the necessary privileges, and that the server is running.
MySQL said: Your password has expired. To log in you must change it using a client that supports expired passwords.
When I look in /tmp folder, I was expecting to find mysql.sock but, instead, there is a file called mysql.sock.lock. Could this be causing the problem? I can't find where that .lock file has come from and I'm not sure what to do about it. Any help would be appreciated.
I'm not entirely sure what happened to cause the root password to expire but something had thrown a spanner in the works. Anyway, the solution for me was to log into MySQL from the Terminal using:
$ mysql -u root -p
...and then alter the root user's password using:
> ALTER USER 'root'#'localhost' IDENTIFIED BY 'NewPass';
That seemed to do the trick. I was then able to log in to MySQL using Sequel Pro with no problems.
Instead of using a socket connection, you could try connecting via Sequel Pro's standard connection using 127.0.0.1 as the host.
Thus spake the 5.7 docs:
The installation process creates only a single root account, 'root'#'localhost', automatically generates a random password for this account, and marks the password expired. The MySQL administrator must connect as root using the random password and assign a new password. (The server writes the random password to the error log.)
So, connect from terminal and change the root password.
Either your first password may not have been saved OR it just truly never persisted.
For me it was the sudo /usr/local/bin/mysql_secure_installation that may not have ever persisted the password correctly. Since your first password never changed, there is no password or ,like your error said, "expired" to nothing.
Run or rerun the code above, don't type anything for the password field and follow the steps, from the preloaded setup program.
I have a mysql database on an unmanaged rackspace cloud server. I can connect to phpmyadmin with no issues. I checked if port 3306 is listening and it is. /etc/mysql/my.conf shows bind-address = 127.0.0.1.
When I use navicat to connect via ssh, it says SSH tunnel: Invalid username or password! I've reset my passwords and restarted mysql and the server just to make sure but I still can't connect. What can I try next to get this working?
Please connect to MySQL and run
SELECT USER(),CURRENT_USER();
What does this output ???
USER() reports how you attempted to authenticate in MySQL
CURRENT_USER() reports how you were allowed to authenticate in MySQL
If the output of these two functions do not match, you will need to create a user that matches the USER() or CURRENT_USER().
If they are both root#localhost, please run
SELECT user,host,password FROM mysql.user;
Now, visible compare if all root users have the same password.
Also, please check the contents of /etc/hosts on the server.
This not fully an answer, but I hope this helps !!!
I have a unix server with mysql which I am trying to access from my machine. To clarify, access the mysql server. When I do I get this error.
Connecting to MySQL server 192.168.1.25...
Can't connect to MySQL server on '192.168.1.25' (10061)
Here are my credentials:
username: root
port: 3306
The server is running because I am able to remotely login onto the machine (with ip: 192.168.1.25" and then run mysql from root. What do you think is going on:
Is it a firewall issue?
Accessing as 'root' is being denied?
I am new to mysql.
1)
check the logs
you can see where the logs are by checking the my.cnf file.
mysqld.log might be the file name, but where
2)
a. see if it's a network issue.
telnet 192.168.1.25 3306
b. see if the service is at that port.
ssh to the box
# from the local host
mysql -u root
telnet 127.0.0.1 3306
ps auxw|grep mysql
you should hopefully have enough diagnostic info at this point to figure it out.
Probably because remote root login is not allowed. You can try this article on how to enable remote root:
http://benrobb.com/2007/01/15/howto-remote-root-access-to-mysql/
i have this problem and fix it by
first you must grant all to user
GRANT ALL PRIVILEGES ON databasename. TO 'user'#'%' IDENTIFIED BY 'password';
then
FLUSH PRIVILEGES;
and change the mysql config using
sudo nano /etc/mysql/my.cnf
find "bind-address" row and comment it.
save config and restart mysql using
sudo /etc/init.d/mysql restart
hope solve problem :)
The Message (10061) is do to offline severs or firewall blockage
If you get -the name of your pc - can not connect, then mysql is rejecting the connection and you will have to create a 'user' in the mysql database mysql, table user using the IP of the remote connection', and restart the database service
but for error 10061 check The Firewall in both machines.
Masters PC per say, is the one with the phpmyadmin installation
Allow Destination ip-[the remote] and port 3306 on the Master Machine
and
Allow source ip-[the masters]/with any port, and check your destination port(3306) too. destination ip can also be set on some firewalls.
And if you can, search in your firewall for logs, settings, recent activity, etc... to see what and how you are being blocked.
