Installation and Set Up

Prerequisites

To run Opus you need a web server which supports PHP4 or PHP5 and access to a MySQL database server. If you are installing Opus on an ISP's web server then they will have done this for you already but if you are putting Opus on your own server then installing both of these packages is fairly straightforward so long as you follow the instructions carefully.

Recent releases of SuSE and RedHat have come with Apache, PHP4 and MySQL configured to work together, which makes life a lot easier.

In our experience the things which are likely to hold you up are giving the user you're running Apache as has the correct access rights to MySQL and getting the permissions right in the directories you'll create in the web server directory tree.

Installation

You need to pick a point in your web server tree where Opus is to be installed. If you can't think of anywhere else then the directory ./opus is as good as any. Unpack the tarball and install it into the that directory. We normally download the tarball into /tmp so we would then do something like this:

cd your_chosen_directory
tar xvzf /tmp/opus.n.nn.tar.gz

Now check the ownership and permissions of the files and directories you've added. Apache needs write access to the ./php/cfg directory. Fix that next. (If you're not worried about security then just set everything to 777 or rwxrwxrwx!)

You can now by pointing your browser at ./php/bin/ which will give you hyperlinks to the the latest version of the documention and to the page to initialise Opus. So read the documentation first and then initialise Opus. The setup pages should be self explanatory.

Once you've got the paper working then read the section on customising the paper.
