when the mysql database is installed in the linux OS, Why I can't connect the mysql database !

try specifying the port too:

168.192.0.1:3306

don't work too.
thank you!

ERROR 2005: Unknown MySQL Server Host '168.192.0.1:3306(11001)

BTW to specify port using mysql client run...

c:\mysql\bin\mysql -h 168.192.0.1 -u root -p12345 -P 3306

The 192.168.0.1:3306 is for telnet.

1.I can ping it.
 2, the mysql is alive ,becuase i can use PHP to connect it.
3, I can't telnet 192.168.0.1:3306 in windows
4 i don't have firewall

thank you !

can you telnet into the linux box normally?

From windows "telnet 192.168.0.1"

You should be able to get a username/login prompt

my linux OS don't open telnet service ,I think I can't telnet it in any way !
thank you !

it sounds to me like your Linux server is blocking outside connections, -or- you've setup mysql on some port other then 3306.  PHP works so I think you have a Linux firewall issue.

Try on Linux ...

"nmap localhost"

and

"iptables -L"

What distribution are you running for Linux?  You may be able to use a GUI tool to open up the port.

when use nmap localhost
Port       State       Service
21/tcp     open        ftp                    
22/tcp     open        ssh                    
25/tcp     open        smtp                    
80/tcp     open        http                    
3306/tcp   open        mysql  

thank you ! I don't how to solve the problem ,But I need to solve it as soon as possiblie!

Mysql is running.  It works on the localhost.  The problem is no outside computer can connect to your Linux box.

Try "/etc/init.d/iptables status" on Linux.  That will tell you if you have a firewall running.

generally, it's a privilege problem. mysql default installation does not allow remote connections. so you must do :

GRANT ALL PRIVILEGES ON *.* TO 'remoteuser'@'%' IDENTIFIED BY 'remotepassword'

take a look at the GRANT syntax in mysql doc for details.

oh duh!

I hope that's right.  I've been building too many servers...

psadac, if it was a privs problem you would be looking at a different error:

ERROR 1045: Access denied for user: 'root@192.168.0.2' (Using password: YES)

You WILL need to add the user though if you haven't done it already - also, don't forget to FLUSH PRIVILEGES after adding your remote user.

STUPID QUESTION.....

are you sure the IP is correct? should 168.192.0.1 not be 192.168.0.1 ?

Mike

yes ,My Ip IS correct.
and I think I have enough rights to access the database ,because the mysql's table" user" have a
recorder
 host user password  Select_priv  
 %   root  12345       Y                  Y Y Y Y
