Navicat 8 For MySQL connection to remote MySQL

Alas, MySQL is too unfamiliar to me. I have never seen it, let alone it.

I used it today. I tried to connect to a remote MySQL instance for a long time, but it was helpless. Unfortunately, I searched for it on the east and found a way to understand the problem, to avoid forgetting.

 

First, you need to enter the MySQL command line client on the remote end. If you lose the root password and execute a statement, it will be OK ......

 

Note:

1. Change the table method.
It may be that your account is not allowed to log on remotely, but only on localhost.
At this time, you only need to log in to MySQL on the computer of localhost, and change the "host" entry in the "user" table in the "MySQL" database to "%" from "localhost"
Mysql> use MySQL;
Mysql> Update user set host = '%' where user = 'root ';
Mysql> select host, user from user;
2. Authorization law. For example, if you want myuser to use mypassword to connect to the MySQL server from any host.
Grant all privileges on *. * To 'loginname' @ '%' identified by 'Password' with grant option;
If you want to allow the user loginname to connect to the MySQL server from the host whose IP address is 192.168.1.6, and use password as the password
Grant all privileges on *. * To 'loginname' @ '192. 168.1.6 'identified by 'Password' with grant option;
I used the first method. I first found that it could not work. I checked it online and executed one less statement mysql> flush rivileges.
Make the modification take effect.
But is there an error in executing flush rivileges here?
3. Another method:
Run the following command on the machine where MySQL is installed:
1. D: \ mysql \ bin \> mysql-H localhost-u Root
// You can access the MySQL server.
2. mysql> grant all privileges on *. * To 'root' @ '%' with grant option
// Grant data access permissions to any host
3. mysql> flush privileges
// The modification takes effect.
4. mysql> exit
// Exit the MySQL server
In this way, you can log on to any other host as the root user.

In the tool navicat 8 from MySQL on the client, add a new connection and enter the corresponding user name, password, and remote address. OK.
