MySQL: External Connection to Database Blocked

Cannot establish an external MySQL connection to the server.

Error 1.  Error 10061: connect to MySQL server failed

Fixed it using the following solution (https://help.ubuntu.com/community/ApacheMySQLPHP)

Solution 1.

Set mysql bind address

Before you can access the database from other computers in your network, you have to change its bind address. Note that this can be a security problem, because your database can be accessed by other computers than your own. Skip this step if the applications which require mysql are running on the same machine.

type:

$ sudo nano /etc/mysql/my.cnf

and change the line:

bind-address           = localhost

to your own internal ip address e.g. 192.168.1.20

bind-address           = 192.168.1.20

If your ip address is dynamic you can also comment out the bind-address line and it will default to your current ip.

If you try to connect without changing the bind-address you will recieve a “Can not connect to mysql error 10061”.

 

Error 2. Host ‘DELL-I660s’ is not allowed to connect to this MySQL server

Solution 2:

(http://www.thegeekstuff.com/2010/08/allow-mysql-client-connection/)

Notes: It is weird that I have to authorize all the IPs from which I will be conecting to the MySQL Database.

$ mysql -h 192.168.1.8 -u root -p

Enter password:
ERROR 1130: Host '192.168.1.4' is not allowed to connect to this MySQL server

You can also validate this by doing telnet to 3306 mysql port as shown below, which will also give the same “host is not allowed to connect to this mysql server” error message as shown below.

$ telnet 192.168.1.8 3306
host 192.168.1.4 is not allowed to connect to this mysql server

If you want to allow a specific client ip-address (for example: 192.168.1.4) to access the mysql database running on a server, you should execute the following command on the server that is running the mysql database.

$ mysql -u root -p
Enter password:

mysql> use mysql

mysql> GRANT ALL ON *.* to root@'192.168.1.4' IDENTIFIED BY 'your-root-password'; 

mysql> FLUSH PRIVILEGES;
