SMF 1.1 Installation Guide

## Installing your forum

Thank you for deciding to use, or at least try, SMF. Before you get started, please remember that there is a place for help at www.simplemachines.org if you run into any problems at all.
If you are looking to upgrade an installation of SMF, or convert from YaBB SE, you may have downloaded the wrong package. Please check the downloads page for more information.

## What's required to install SMF?

Your server must meet a few requirements to be able to run SMF. If you unsure as to whether your webserver meets these, please try the installer - it should detect any problems.

- Any webserver that properly supports PHP, such as Apache or Internet Information Services (IIS).
- PHP 4.1.0 or higher. The following directives are required to be set correctly in php.ini:
  - the engine directive must be On.
  - the magic_quotes_sybase directive must be set to Off.
  - the session.save_path directive must be set to a valid directory.
  - the file_uploads directive must be On.
  - the upload_tmp_dir must be set to a valid directory.
- MySQL 3.23.28 or higher.
- at least 512 kilobytes of storage space in the database, although more is highly recommended.
- about two and a half megabytes of storage space on the web server, although more is recommended.

Recommendations for best performance:

- Linux or another Unix based operating system.
- the GNU Aspell and its dictionaries for spell checking support.
- Apache with AcceptPathInfo set to On (Apache 2 and later only) for queryless URL support.
- PHP 4.3.0 or higher, with the following set in php.ini:
  - the max_input_time directive is set to a value of at least 30.
  - the post_max_size and upload_max_filesize directives are set to the size of the largest attachments you wish to be able to upload.
  - the session.use_trans_sid directive set to Off.
  - the memory_limit directive is set to at least 8M.
  - the max_execution_time directive is set to at least 15.
  - the register_globals directive is set to Off.
- MySQL 4.0.15 or higher with query caching enabled.
- GD Graphics Library 2.0 or higher.

If your server does not meet these requirements, SMF may not work properly.

## Uploading the files

The first thing you need to do is upload all of the files in this package, excluding this file itself, to your server. You can upload it to any directory accessible by URL, but if you're not sure where to put it, a directory named "forum" is a good choice. You may wish to make sure that all of the folders were uploaded, such as `Themes/default/languages`, because some FTP clients have been known to drop files.
If you want or need to install any languages other than English, download the corresponding versions from the download page, and upload them to the same directory you uploaded SMF to. This should put additional files in `Themes/default/languages` and, in most cases, `Themes/default/images`.
After you have finished uploading the files, point your browser to http://www.yourdomain.tld/forum/install.php - where www.yourdomain.tld/forum is the URL to where you uploaded it. You should then see an installer interface.
The first page you see may request your FTP information. If you see this screen, it is because the installer found some files or folders with inadequate permissions for SMF to run properly. If you enter your FTP information here, the installer can automatically fix these permissions for you. Please note that the path should be the same path you see in your FTP client. For example, it might be "public_html/forum". And remember, the installer will not save your FTP password anywhere.

## Finishing everything up

From this point, the installer should walk you through all the information you need to enter. There isn't much more, so don't worry.
Please remember to delete the installer after finishing the installation. If you do not delete it, it is possible that someone could compromise the security of your forum.
Good luck!
