How to access the MySQL database in Linux?
MySQL database was installed in Linux not long ago, but Linux is a virtual machine, and the Real host is Win7, I tried to use MySQL database tools under Windows 7 to access the MySQL database in Linux. However, a problem occurs during the connection process:
Host '192. 168.0.101 'is not allowed to connect to this MySQL server
Then I tried Baidu to solve this problem and found the following solutions.

Method 1: (modify a table)
Go to the mysql database in Linux, open the user table, find the record with the "host" field value as "localhost", and update the value "localhost" to "% ".
The command is as follows:
# Mysql-u root-p
Enter password:
Mysql> use mysql;
Mysql> update user set host = '%' where user = 'root' and host = 'localhost ';
Mysql> select host, user from user;

Method 2: (authorization)
Example 1
If you want myuser to use mypassword to connect to the MySQL database server from any host. Use the following authorization command:
Grant all privileges on *. * TO [email = 'myuser' @ '%'] % 27 myuser % 27 @ % 27% % 27 [/email] identified by 'mypassword' with grant option;
Example 2
If you want to allow myuser to connect to the MySQL database server from a host with IP address 192.168.0.101 and use mypassword as the password. Use the following authorization command:
Grant all privileges on *. * TO [email = 'myuser' @ '192. 168.0.101 '] % 27 myuser % 27 @ % 27192.168.0.101% 27 [/email] identified by 'mypassword' with grant option;
The above two methods are obtained from the Internet. I solved my problem through example 1 in the second method and successfully connected the MySQL database server in Linux. BitsCN.com
