Line 118: − ===Using RPMs===+ − Since SME Server is based on CentOS, the preferred way to install software is with yum, a lot of you might be familiar with its predecessor rpm. − To install an RPM already on your system you can also use yum to install: − − yum localinstall /path/to/filename.rpm − − To satisfy dependencies you can enable or disable other repositories using the --enablerepo or the --disablerepo option. − {{Note box|msg=Using yum will run other actions such as updating server-manager menus, that rpm -Uvh will not!}} − −

yum --enablerepo=dag install dansguardian
yum --enablerepo=dag install packagename
====Localinstall====
To install an RPM already on your system you can also use yum to install:
yum localinstall /path/to/packagename.rpm
To satisfy dependencies you can enable or disable other repositories using the --enablerepo=xxx or the --disablerepo=xxx option.
{{Note box|msg=Using yum will run other actions such as updating server-manager menus, that rpm -Uvh will not!}}
===Yum Repositories===
===Yum Repositories===
Yum repositories on SME Server are to be configured by the internal configuration database. Repositories are stored in the yum_repositories database. The yum configuration file, located at /etc/yum.conf holds the actual configuration and is generated using the data in the yum_repositories database.

====Checking status of installed repositories====
To check which repositories are installed and their status do
/sbin/e-smith/audittools/repositories
On an unmodified sme server only the following are enabled
base: enabled
smeaddons: enabled
smeextras: enabled
smeos: enabled
smeupdates: enabled
updates: enabled
Any other repository that is installed and listed should have a status of disabled.
This is to prevent the inadvertant and potentially undesirable update of packages.
To update packages from other repos, use the --enablerepo=reponame switch in the yum update command eg
yum update --enablerepo=dag
which will also bring in any rpm updates from the dag repo (only for packages that are already installed on your system). See more details below.

For the syntax of modifying or adding see the examples below in the 3rd-Party Yum Repositories setup section. For more details on the configuration database and how to work with it you can have a look at the [http://mirror.contribs.org/smeserver/contribs/gordonr/devguide/html/book1.htm SME Server Developer's Guide].

After adding or modifying the yum_repositories database you will have to make sure you regenerate the configuration file using the following command:

If you use the commands below to add 3rd party yum repositories, they will be added to the yum-repositories database, but not enabled by default, so this will not affect automatic yum upgrades. It only adds options for running yum manually. They are also set up to block you from installing RPMs that exist already in SME Server 7.0.

To reflect the changes in the database you will have to regenerate the yum.conf file:
