Set up MySQL to allow extranet access

Set the MySQL service to allow extranet access, modify the MySQL configuration file, some my.ini, some my.cnf "Linux".

1: Setting up the MySQL configuration file
/etc/mysql/my.cnf
Find Bind-address =127.0.0.1 to comment out;//function is to make it no longer allow only local access;

Restart Mysql:/etc/init.d/mysql restart;

2: Log in to MySQL database : mysql-u root-p
mysql> use MySQL;

Query the host value:
Mysql> select User,host from user;

If there is no "%" of this host value, the following two sentences are executed:
mysql> Update user set host= '% ' where user= ' root ';
mysql> flush Privileges;
Or you can do it:
Mysql>grand all privileges on * * to [E- Mail protected]'% ' identifies by ' XXXX ';
Where the first * represents the database name, the second * represents the table name of the database, and if the *. * As above indicates that all the tables are allowed access under the database;
'% ': Indicates an IP address that allows access to MySQL, and of course you can configure it to a specific IP name;% means that all IPs can be accessed;
Back to ' xxxx ' for root user's password;

Example:

Any host connected to the MySQL server with user root and password mypwd
Mysql> GRANT All privileges on * * to ' root ' @ '% ' identified by ' mypwd ' with GRANT OPTION;
mysql> flush Privileges;

Hosts with IP 192.168.1.102 connect to MySQL server with user myuser and password mypwd
Mysql> GRANT All privileges on * * to ' myuser ' @ ' 192.168.1.102 ' identified by ' mypwd ' with GRANT OPTION;
mysql> flush Privileges;

MySQL root account, I usually use the connection is localhost or 127.0.0.1, the company's test server mysql is also localhost so I want to access inaccessible, test paused.

Here's how to fix it:

1, modify the table, log in to the MySQL database, switch to the MySQL database, use the SQL statement to view the "select Host,user from User;"

Mysql-u root-pvmwaremysql>use MySQL;
Mysql>update User Set host = '% ' where user = ' root ';
Mysql>select host, user from user;
Mysql>flush privileges;

Note: The last sentence is important in order for the changes to take effect. If you do not write, you still cannot connect remotely.

2, authorized user, you want root to connect to MySQL server from any host with password

GRANT all privileges on * * to ' root ' @ '% ' identified by ' admin123 ' with GRANT OPTION;
Flush privileges;

If you want to allow user root to connect to a MySQL server from a host with IP 192.168.1.104

GRANT all privileges on * * to ' myuser ' @ ' 192.168.1.104 ' identified by ' admin123 ' with GRANT OPTION;
Flush privileges;
