Selecting data from mysql using qt?

Dii

ok then the wrong socket guess was wrong... but let's make it sure:

sudo ls -l /var/run/mysqld/*

doforumda

after running this sudo ls -l /var/run/mysqld/* there is nothing inside run directory

Dii

uhmmmmmmm that's more than strange, the socket file should be there somewhere, let's find it:

find /var -name mysqld.sock

if no result:

find /opt -name mysqld.sock

doforumda

both of them didnt return any resutl

@
root@zafar-laptop:/# find /var -name mysqld.sock
root@zafar-laptop:/# find /opt -name mysqld.sock
root@zafar-laptop:/#

I have bitnami lampp stack installed and when I start it then the socket file is created in /opt/lamppstack/mysql/tmp/mysql.sock. I think doforumda shoudl have similar directory and we need to check the permissions for that directory.

Dii

Usually that means, that the mysql daemon is not running... but the the command line should not work as well... ;(

It doesn't hurt to try to start the daemon:

sudo /etc/init.d/mysql start

... and do the search for the socket file as above.

Dii

gosh, do the find with sudo:

sudo find /opt -name mysqld.sock
sudo find /var -name mysqld.sock

damn, I always forget that with ubuntu

Dii

lyuts: yes, if he have the socket file at the same place, we need to symlink it to the /var/... location and happy end :) I hope so.

doforumda

tyut: yes i have one file with the name of mysql.sock in /opt/lampp/var/mysql/mysql.sock

doforumda

the permissions on mysql.sock it read write exe for all types of users

Dii

Great, don't give up, we are close :D

ls -l /opt/lampp/var/mysql/*

maybe you have another mysql config file somewhere:

ls -l /opt/lampp/etc/my.cnf
or
ls -l /opt/lampp/etc/mysql/my.cnf
?

Dii

gosh... all with sudo please

doforumda

i got this output from this command sudo ls -l /opt/lampp/var/mysql/*

the output is too long so i am posting it in pieces

root@zafar-laptop:/# sudo ls -l /opt/lampp/etc/my.cnf

Dii

ok doforumda, that's enough... I want to make it sure, can you check, the
sudo ls -l /opt/lampp/etc/my.cnf
or
sudo ls -l /opt/lampp/etc/mysql/my.cnf
?
If one of them is there, let's take a look with gedit, for the
socket = /something
part?

Dii

ok, then
sudo gedit /opt/lamp/etc/my.cnf

look for the socket = something line
