mysql database location?

[sdowney717]

where are the databases located?

how to open up the lan to database queries?

I tried to login from an XP machine to my ubuntu mysql server and cant.
When I explore the network from XP, it shows my ubuntu desktop as part of the workgroup.

Hi,

Your database is location in /var/lib/mysql/"DB-Name"

What are you using to try and login?

If you have firewalls installed you will need to open up the port for mysql and you may also have to all access via your hosts.allow file
Rgds

[sdowney717]

Thanks, I copied the database into that folder

a windows based library program I wrote myself that uses mysql.
hosts.allow file, so I will check that out.

I recall something about that file when I did this before.

[chrislynch8]

Not sure if copying a database to that folder will work, I think you might need to add the database using proper sql commands.

I have SQLyog here so I access my DB server using 192.168.1.250:3306

In my hosts.allow I have a line mysqld: ALL

Also in you my.conf file make sure that your Mysql instance is listening on the correct LAN interface. By default it may be looking at 127.0.0.1 by default so you will have to change this to listen on the LAN address instance

added ALL: ALL

# /etc/hosts.allow: list of hosts that are allowed to access the system.
# See the manual pages hosts_access(5) and hosts_options(5).
#
# Example: ALL: LOCAL @some_netgroup
# ALL: .foobar.edu EXCEPT terminalserver.foobar.edu
#
# If you're going to protect the portmapper use the name "portmap" for the
# daemon name. Remember that you can only use the keyword "ALL" and IP
# addresses (NOT host or domain names) for the portmapper, as well as for
# rpc.mountd (the NFS mount daemon). See portmap(8) and rpc.mountd(8)
# for further information.

stll not connecting yet, and turned off the XP firewall
Will try a reboot


OTHER ISSUE is a database I created with server 5.05
apparently has trouble with server 5.1?

scott@scott-desktop:~$ mysql -u root -p

yes, showing 127.o.o.1 in
my.cnf

so change it to reflect the client trying to connect or the address of the host?

getting closer, now the message is the machine is not authorized
At least it sees the server.

what next?

[sdowney717]

had to run a grant command
NOW it connects!

GRANT ALL ON *.* TO 'root'@'192.168.1.%' identified by 'MY_PASSWORD';

http://ubuntuforums.org/archive/index.php/t-253153.html

having a very hard time with the forum server responding

[sdowney717]

basically had to do 3 things to make it work connecting outside the box the server is running on

modify the hosts.allow file
modify my.cnf file set bind field to the ip address of the host
execute grant statement

GRANT ALL ON *.* TO 'root'@'192.168.1.%' identified by 'MY_PASSWORD';

a couple nice programs are
mysql-query-browser
mysql-admin
