Had to do a fresh install of Sun's Java on a remote Ubuntu machine this weekend. It's pretty easy to do in a graphical environment, but I only had ssh access. Since I couldn't find a set of instructions on how to install Sun's Java from the command line, I thought I'd put together my own how-to.
You'll use the apt-get command to grab the Sun java .deb files and install them. It works just like a command-line version of the Synaptic Package Manager you probably used to install software from the graphical environment.
But apt-get doesn't know how to find the Sun Java files unless you add some sources to its repositories: a list of all the places apt-get looks for software.
Once you've added the repositories to the source list for apt-get, one command will install everything for you. Here's a step-by-step way to do it:
- Type "nano /etc/apt/sources.list" to open a command-line text editor to edit the list of repositories apt-get will look through.
- You'll see some lines, starting with "deb" or "deb-src" already in the file. Add the following lines to the file:
deb http://us.archive.ubuntu.com/ubuntu/ hardy universe deb-src http://us.archive.ubuntu.com/ubuntu/ hardy universe deb http://us.archive.ubuntu.com/ubuntu/ hardy-updates universe deb-src http://us.archive.ubuntu.com/ubuntu/ hardy-updates universe
deb http://us.archive.ubuntu.com/ubuntu/ hardy multiverse deb-src http://us.archive.ubuntu.com/ubuntu/ hardy multiverse deb http://us.archive.ubuntu.com/ubuntu/ hardy-updates multiverse deb-src http://us.archive.ubuntu.com/ubuntu/ hardy-updates multiverse
- Press Ctrl-O to save the file. Press Return to agree to name the file sources.list, then press Ctrl-X to leave the editor.
- Type: "apt-get update"
- Type: "apt-get install sun-java6-jdk"
That should do it!
