setting password for mysql user in startup

Hi ,
I am using mysql in linux .

Code:

$ mysql --version

mysql  Ver 14.14 Distrib 5.5.17, for Linux (i686) using  EditLine wrapper

I have added following line in startup script

Code:

sudo mysqladmin -u root password root123

Still when I try to run a jar file , I get

Quote:

Now after I run startup command manually in terminal , then jar file works .

Any ideas ?

None of that makes any sense, actually...

Are you referring to the mysql start script where you are setting the password?

Why would you set a root user password from the startup script?
And why would you think that would enable a client to connect to a database server?

Why would you think that had anything to do with running a jar file?
What connection parameters are set for the connection and how does the java program use them?

These are not rhetorical questions, perhaps your application instructs you to do this, but it is very strange.

Also, what distro, what java application, what does the application documentation say is required for the db connection?

Much more information would elp.

i am using tiny core 4.7.7
i have installed mysql.tcz

Code:

~$ java -version

java version "1.7.0_03"

Java(TM) SE Runtime Environment (build 1.7.0_03-b04)

Java HotSpot(TM) Server VM (build 22.1-b02, mixed mode)

my jar file wants that user root should have password root123 then it can access database gponlct
I even added following script in startup to check if my sql is running then set password

Code:

#!/usr/local/bin/bash

if pgrep mysqld

then

        echo mysql running > /home/tc/mysql-log

        sudo mysqladmin -u root password root123

        echo root password for mysql set to root123 > /home/tc/mysql-log

else

        echo mysql-not-running > /home/tc/mysql-log

fi

I got /home/tc/mysql-log with
'mysql running
root password for mysql set to root123'

But password has to be set again in terminal , like before .

even created file .my.cnf

Code:

[client]

user=root

password=root123



[mysql]

user=root

password=root123



[mysqldump]

user=root

password=root123



[mysqldiff]

user=root

password=root123

in /root & /home/tc

The problem persists .
