EAR includes the specification files to create an rpm from an already existing installation.
The spec file is placed at `etc/rpms`.
To create the RPM it is needed a valid installation from source.
The RPM can be part of the system image.

### RPM requirements
EAR uses some third party libraries. EAR RPM will not ask for them when installing but they must be available in `LD_LIBRARY_PATH` when running an application and you want to use EAR.
Depending on the RPM, different version must be required for these libraries:
| Library | Minimum version | References |
| ----------- | --------------- |----------------------------------------------------------------|
| MPI | - | - |
| MySQL\* | 15.1 | [MySQL](https://mysql.com) or [MariaDB](https://mariadb.org/) |
| PostgreSQL\* | 9.2 | [PostgreSQL](https://www.postgresql.org/) |
| Autoconf | 2.69 | [Website](https://www.gnu.org/software/autoconf/autoconf.html) |
| GSL | 1.4 | [Website](https://www.gnu.org/software/gsl/) |
\* Just one of them required.
These libraries are not required, but can be used to get additional functionality or metrics:
| Library | Minimum version | References |

| SLURM | 17.02.6 | [Website](https://slurm.schedmd.com/) |

Also, some **drivers** has to be present and loaded in the system when starting EAR:

| CPUFreq | kernel/drivers/cpufreq/acpi-cpufreq.ko | 3.10 | [Information](https://wiki.archlinux.org/index.php/CPU_frequency_scaling) |

## Starting Services
The best way to execute all EAR daemon components (EARD, EARDBD, EARGM) is by the unit services method.
> __NOTE__ EAR uses a MariaDB/MySQL server. The server must be started before EAR services are executed.
The way to launch the EAR daemons is via unit services. The generated unit services for the EAR Daemon, EAR Global Manager Daemon and EAR Database Daemon are generated and installed in `$(EAR_ETC)/systemd`. You have to copy those unit service files to your `systemd` operating system folder and then use the `systemctl` command to run the daemons.
Check the [EARD](Architecture#ear-node-manager), [EARDBD](Architecture#ear-database-manager), [EARGMD](Architecture#ear-global-manager) pages to find the precise execution commands.
When using `systemctl` commands, you can check messages reported to `stderr` using `journalctl`. For instance:
`journalctl -u eard -f`. Note that if `NodeUseLog` is set to 1 in `ear.conf`, the messages will not be printed to `stderr` but to `$EAR_TMP/eard.log` instead. `DBDaemonUseLog` and `GlobalmanagerUseLog` options in `ear.conf` specifies the output for EARDBD and EARGM, respectivelly.
Additionally, services can be started, stopped or reloaded on parallel using parallel commands such as `pdsh`. As an example:
`sudo pdsh -w nodelist systemctl start eard`.
## Updating EAR with a new installation
In some cases, it might be a good idea to create a new install instead of updating your current one, like trying new configurations or when a big update is released.
