Recently, I installed Mysql on Linux, and then connected through Navicat under Windows environment, an error occurred: 1045 Access denied for user'root'@'XXX' (using password: YES), as follows:
First of all, it is possible to log in to mysql normally in Linux, so it will not be caused by a wrong user password.
Next, I considered that it might be related to the firewall, so I checked whether the firewall under Linux has opened the corresponding port, and found that the firewall is closed at this time, so the influence of the firewall can be excluded.
Finally, it suddenly occurred to me that the root user of mysql cannot connect remotely by default, so I logged into mysql in Linux and found that this is the reason. The solution is as follows:
- 1. Log in to mysql, command:,
mysql -u root -pand then enter the password.
- 2. View the host field of the user table in the mysql library
Use mysql library: use mysql query information: select user,host from user
In the host field, localhost means that only the local machine is allowed to access. To realize remote connection, you can change the host of the root user to %,% means that any host is allowed to access. If you need to set to allow only specific ip access, you should change to the corresponding ip .
- 3. Modify the host field of the root user, command:
update user set host="%" where user="root" - 4. To make this modification effective immediately, order:
flush privileges
Finally, if you connect remotely in Navicat under windows, no error will be reported.
