1, XAMPP under Linux How to use the MySQL command

A:

1. Workaround (Recommend a second method):
2. 1, the command tool in XAMPP in the/opt/lampp/bin/directory, so you can run the MySQL command
4. /opt/lampp/bin/mysql-uroot-p
6. 2, you can also enter the/opt/lampp/bin/directory to execute the MySQL command
8. cd/opt/lampp/bin/
9. ./mysql-uroot-p

2. mysql Remote connection error: Host * is not allowed to connect to this MySQL server

A:

GRANT All Privileges

1. Change the table method. It may be that your account is not allowed to log on remotely, only on localhost. This time, as long as the computer on the localhost, log in to MySQL, change the "MySQL" Database in the "User" table "host", from "localhost" to "%"

1. mysql-u root-pvmwaremysql>use MySQL;
2. Mysql>update User Set host = '% ' where user = ' root ';
3. Mysql>select host, user from user;

2. Authorization law. For example, if you want to myuser use MyPassword to connect to a MySQL server from any host.

SQL code Copy Code

1. GRANT all privileges on * * to ' myuser ' @ '% ' identified by ' MyPassword ' with

GRANT OPTION;
2.FLUSH privileges;

If you want to allow users to connect to the MySQL server from a host myuser IP 192.168.1.6 and use MyPassword as the password

SQL code Copy Code

1. GRANT all privileges on * * to ' myuser ' @ ' 192.168.1.3 ' identified by
2. ' MyPassword ' with GRANT OPTION;
3. FLUSH privileges;

GRANT all privileges on * * to ' myuser ' @ ' 192.168.1.3 ' identified by
' MyPassword ' with GRANT OPTION;
FLUSH privileges;

A different approach.

(This method is recommended) to run on a MySQL-installed machine:
1. d:\mysql\bin\>mysql-h Localhost-u Root
This should allow access to the MySQL server
2, Mysql>grant all privileges on * * to ' root ' @ '% ' with GRANT OPTION
Give any host access to data
3, Mysql>flush privileges
Changes take effect
4, Mysql>exit
Log out of MySQL server
This will allow you to log in as root on any other host!

Reference: GRANT all privileges restricts one or all clients from being able to connect to MySQL
