MachDB 0.5.2 Apr 16 2009 Nathan Hubbard machdb (at) unmx.com BASIC: MachDB is a machine database that lets you catalog and track information about your hosts. It consists of an information collector, a web front end and scripts that live on each host that gather the data. A few sample gathering scripts have been provided in the contrib directory of the machdb distribution. You can use this as a template for your own scripts, or write them in any language you choose. The data sent back to the aggregator is sent as an XML file (that can be generated however you wish). Again, you can use the contributed gathering scripts as a template, or see the XML specification to create your own. I would recommend scanning the machdb.org wiki for instructions specific to your distribution. If there aren't any, add them! If you are upgrading from a previous version, please see the information in the CHANGELOG For the latest information, documentation and FAQ, please visit http://www.machdb.org AUTO INSTALL: Run contrib/setup.sh to auto-configure. It will attempt to do the install of XML::Simple and LWP perl modules, but use at your own risk. MANUAL INSTALL: Create a directory with root permissions: /var/machdb. This is where the XML output is stored before being shipped off to the collector You will need XML::Simple and LWP to use the example XML gathering (gather-centos4-i386) and posting (machdb-send) tools. Others may require other libs but we will assume this basic need. With CPAN: perl -MCPAN -e shell > install XML::Simple > install LWP XML::Simple RPM downloaded from: http://dag.wieers.com/rpm/packages/perl-XML-Simple/ I install the gathering and sending scripts in /usr/local/sbin on my hosts, but you can put them anywhere you like. They must be run as root (although I'm sure that could be changed as well). They are separated to keep the information gathering and sending abstracted by OS. INSTALLING THE MACHDB BACKEND MachDB was developed on MySQL 5.0.27, PHP 5.1.6, Apache 2.0.59 and Smarty 2.6.18. Your mileage on other versions may vary, however I would recommend at least PHP 5 and MySQL 5. Extract the tarball somewhere in your web root. You will need to install Smarty (http://smarty.php.net/). Make sure Smarty is in your PHP_INCLUDE_PATH. Put the files within the 'collect' directory somewhere in your webroot. Suggested path is: $WEBROOT/machdb/collect/ This URL should be accessable via HTTP from the machines you will be polling. You can set up access control using your webserver's access control settings. Better security will be built into the collector in the future. If you require encryption, put the collect script behind an HTTPS/SSL webserver and modify the machdb-send script to use HTTPS. An HTTPS example is included. Once you've untarred it, you will need to set certain permissions for the smarty cached templates: cd $WEBROOT chown -R apache:apache smarty/cache/ chown -R apache:apache smarty/templates_c chmod -R 775 smarty/templates_c chmod -R 775 smarty/cache/ Where 'apache' is the user your webserver runs as. Create a MySQL DB for machdb to use. Run the database.sql script to create your DB mysql -u mysqluser -p mysqldatabse < database.sql Modify machdb-send to point to your webserver and correct URL path. Modify include/config.php to add your own mysql settings. UPGRADING If you are upgrading from a previous version, please see the php and .sql scritps for upgrading. You would run these like this: php contrib/update_0.5.0-0.5.1.php mysql -u mysqluser -p machdb < contrib/update_0.5.0-0.5.1.sql The PHP script should do the trick for most people, although you should inspect it to make sure your any custom schema will not be destroyed. The sql version is there for custom users to take apart. CLIENT USAGE: From the machine you want to add to the db, go into the 'contrib' directory and run the example gathering tool: ./gather-centos4-i386 Which will output an XML file into /var/machdb/ To send the data off to the collector, go into the 'bin' directory and run the example XML sending tool: ./machdb-send To see the fruits of your work, point your browser at the web root where you installed machdb. ALPHA WARNING You are welcome to use this software, but be ware: I am still making major architectural decisions. There may be future upgrades in the future that will have no migration path. You have been warned! Feedback welcome! I am sure this is full of bugs, but I'll never know without feedback!
