How can i turnoff redhat linux server's firewall?and what is the basic command for installing a rpm package.I tried installing mysql workbench by this command:rpm -ivh packagename.rpm
but it didnt work.Can anyone please help me

Hi,

Please be aware of the security implications when you turn off the firewall! It is good practice to use the firewall even when your computer is located inn a trusted network.

Having said that:
To turn off the firewall you need to be root:
service iptables stop
And to avoid it will start at next reboot:
chkconfig iptables off

To search and install the package(s) that you need use yum, not rpm:
yum search mysql
yum install <packagename(s)>

Don't forget: man is your friend! (man yum)
And so is google.

I hope this helps.
Lucas

Check the rpm details that you have downloaded. If it is incompatible with your current OS architecture then the installation fails. The command you are using is correct. "rpm -ivh pkgname.rpm" does the trick.

Yes Lucas , i have already searched using yum but latest mysql workbench was not available on my redhat 6.3.So i downloaded a rpm package mysql workbench installer and tried to install that,but couldnt install.

I am guessing that that rpm is for a different operating system
from the mysql site it is a fedora 17 rpm

And that is very incompatible with RHEL6.3

There is a reason you are using Red Hat -- it is VERY stable .
That entails that the versions of programs are a bit "old" .Old BUT patched with the current security patches .
also the version of a program will NEVER change over the life time of the os ( for RHEL 6 that is 10 years )

you could always build from source ,then using "rpm-build" convert it to a rpm package for install.

There is a "src" source code rpm for RHEL6
http://www.mysql.com/downloads/workbench/#downloads
"mysql-workbench-gpl-5.2.45-1el6.src.rpm"
you will need to build the program
