I have downloaded mysql-5.5.9-linux2.6-i686.tar.gz file. I don't know how to install it into my Ubuntu os. I don't have an internet connection, I'm posting here from browsing center. I can download files from here, but I can't connect my laptop directly to the internet. Is there any way to install mysql while offline?
When installing things on Ubuntu, you're much better off using packages provided for your version of Ubuntu, rather than from other sources.
To install a package offline, you can do something like this:
apt-get install --print-uris mysql-server
This will print out a bunch of URLs. You can download these from another computer, and transfer them to your Ubuntu machine, putting the .deb files into
Once you've done that, do:
sudo apt-get install mysql-server
And apt will find the package files you've downloaded, and install mysql.
