Unix System Requirements

Before installing FogBugz for Unix, you should run through this checklist to make sure your server has all the required components. If you are missing anything, we maintain a list of helpful links and advice. 

NOTE: If you are planning to install this on a shared Unix host, it will require command-line access and possibly root access unless the host environment already matches all of the listed requirements.  Ask your host provider before installing if they will be amenable to helping you with making the installation work.

Computer

FogBugz for Unix runs on 100% Intel-compatible computers (386, 486, Pentium, etc.). Other CPUs will not work. Please contact Fog Creek Software first if you need to run FogBugz on any other server.

Operating System

Note: Some operating systems now come loaded with experimental ZTS (Zend Thread Safety). FogBugz is not compatible with ZTS, so  you will need to disable ZTS in PHP before installing FogBugz.  

Note: FogBugz is not supported under SELinux. You will need to disable SELinux if it is included as part of your distribution.

The operating systems listed below have been tested at Fog Creek Software. FogBugz 6 supports both 32-bit and 64-bit Linux architectures. FogBugz 6 requires PHP5.1 or PHP5.2, so earlier versions of these distributions may require a PHP upgrade before installation.

• CentOS 5
• Debian Etch and higher (pre-install help)
• FreeBSD 5.2 and higher (pre-install help)
  • FreeBSD 5.3 comes loaded with ZTS (Zend Thread Safety). Disable this in PHP and you should be fine.
  • You must install both the php package and the php extensions package.
• Fedora Core 5 and higher (pre-install help)
• Gentoo (pre-install help)
• Gentoo is a meta-distribution, so we cannot support every possible configuration. A default profile with no modifications that affect binary compatibility is most likely to work.
• Apache must be emerged WITHOUT the threads option so that PHP does not build with ZTS (Zend Thread Safety)
• Mac OS X 10.4 and higher
• Mandriva (pre-install help)
• Red Hat Enterprise Linux 4 and higher
• Suse 10
• Ubuntu Feisty Fawn and Gutsy Gibbon (pre-install help)

Other versions of Linux that are binary compatible with these may work, but we have not yet tested them (aside from comments included in the above list). We do offer a 90-day, no questions asked money back guarantee, so if you like, you could buy one license, try installing, and if it does not work, we will issue a refund. However, we cannot currently provide installation support for platforms not on the list of supported platforms.

If your platform is not currently supported, we may be able to compile our FogBugz shared object to that platform if you give us SSH access with permissions to compile. Contact us for further details or to let us know about platforms you'd like us to support in the future.

Not sure what platform you have? Type uname -a at the command prompt.

Apache HTTP Server
www.apache.org

Must be installed and running.
Version required: 1.3 or 2.0.

Not sure if Apache is running? The easiest way to tell if Apache is running on your server is to point a web browser at it. For example, from the command line, type lynx http://localhost

Not sure what version you have? If apache is running, the command apachectl status will usually tell you what version you have. Or you can try to download a page that doesn't exist, which will display an error message containing the version of Apache. For example, type lynx http://localhost/xxxx

PHP Scripting Language
www.php.net

Must be installed with the following extensions compiled in, or available as extensions:

• xml
• iconv
• imap
• mysql

Must be installed without the debug and ZTS options.

Make sure safemode=Off in your php.ini file or the install will not be able to run.

Version required: PHP 5.1 or higher

Not sure if it's installed? Create a file named test.php in a directory which is served by your web server. Copy the following text into that file:

<?
echo PHP_VERSION . "<br>";
echo "XML:" . extension_loaded('xml') . "<br>";
echo "imap:" . extension_loaded('imap') . "<br>";
echo "mysql:" . extension_loaded('mysql') . "<br>";
echo "iconv:" . extension_loaded('iconv') . "<br>";
?>

Now browse that new page with a web browser, for example, lynx http://localhost/test.php

• If you see either the PHP source code itself, or your web browser offers to download the file to you, this means your HTTP server is not configured to run PHP files. See the PHP documentation for instructions on configuring Apache to run PHP files.
• If PHP files are running, you will see the php version in the first line. Check that it is 5.1.6 or later.
• The next three lines tell you whether php was compiled with xml, imap, and mysql support, respectively. If they are, you will see the number 1 after the colon. For example:

5.1.6
XML:1
imap:1
mysql:1
iconv:1

If any line is missing the 1, that means that this extension is not compiled into PHP and FogBugz will not work.

PHP Command Line Interface (CLI)
http://ca2.php.net/manual/en/features.commandline.php

Must be installed. This is a version of the PHP scripting language which runs from the command line.

The following extensions must be compiled in:

• xml
• imap
• mysql
• iconv

Must be installed WITHOUT the debug and ZTS options.

Version required: PHP 5.1 or higher

Not sure if it's installed? The command php -v will try to run it and tell you what version you have.

Not sure if you have all the right extensions compiled in?

Issue the command

php -m

Look for xml, imap, and mysql in the list of extensions. If any one of these is missing, you will need to recompile or configure PHP to include the appropriate extensions.

pear must also be in your path or in /usr/local/php/bin/pear.  Type which pear to find out whether your path includes the pear binary.

MySQL Database Server
www.mysql.com

Client and Server must be installed and running.

Version required: 4.1 or later

Not sure if it's installed and running? Type mysql at the command line.

• If you get "command not found," you probably don't have mysql installed, or it might not be in your path.
• If you get "Can't connect to local MySQL server," it's possible you only have the client installed, or it could be that the server (mysqld) is simply not running.
• If you get "Welcome to the MySQL monitor" you're probably in good shape. It should also tell you what version you're running.
• Try typing use test; at the mysql prompt. If you get the message Database changed you are definitely in good shape. Type quit to exit.

Curl Command line tool
curl.haxx.se

Must be installed.

Not sure if it's installed? Type curl --version at the command line. If it is installed, you will see a version number. If you get the message "command not found," install curl.

Mono Open Source .NET

Version 1.2.3 or higher must be installed.

More info: http://www.mono-project.com/

eAccelerator PHP optimizer and cache
eaccelerator.net

Recommended. Radically improves performance of PHP FogBugz.

Not sure if it's installed?

Issue the command

php -m | grep eAccelerator

• If you get no results, eAccelerator is not installed

You can find download and installation instructions on the eAccelerator install page. Binary packages are available for most operating systems.

For Email Integration

For FogBugz to send email, you need an SMTP server. If you have the ability to send Internet email, you probably already have one of these somewhere.

For FogBugz to receive incoming mail, you need a POP3 server. FogBugz supports plain POP3 and secure (ssh-based) POP3. Almost all email servers support POP3.

For Source Code Control Integration

We support integration with Perforce, CVS, Subversion, Visual SourceSafe, and Vault. Other source code control systems may work if they support some form of triggers and have a web interface. More info.
