Install 7Zip on CentOS 5.5

We will use Yum.

Because 7Zip is not automatically included in CentOS 5.5, we have to add the repository and then install it. Reference

Download the i386 rpm file onto the 64-bit Opteron server because

 uname -i 

reported i386. That was a surprise.

• Install DAG's GPG key
• Install the package

Then yum can be used, like this:

 yum install p7zip

And then you can run

/usr/libexec/p7zip/7za

to make your .7z files.
