2.7. Installing the Engine
The EVMS Engine consists of the user-space plug-ins and interfaces as well as a stand-alone
library, dlist, that the Engine uses for linked-list management.
2.7.1. Installing from source
To build and install the Engine from source, first type the following command to change to the /usr/src/evms-2.0.0 directory:
Select the appropriate options for your configuration.
 | NOTE |
|---|
| | A list of options can be found by typing: |
Configure your engine:
Type the following commands:
make
make install
ldconfig
|
Unless you specified other directories when you configured the engine, the
following list describes where files will be installed
on your system:
The core Engine library is installed in
/lib.
The core dlist library is installed in
/lib.
All plug-in libraries is installed in
/lib/evms.
All user interface binaries are installed
in /sbin.
All header files are installed in
/usr/include/evms.
All manual pages are installed in /usr/man.
Add the Engine library path to your
LD_LIBRARY_PATH environment variable, or to
your /etc/ld.so.conf file. Do not add the
plug-in library path because the Engine dynamically loads
these libraries directly.
Examine the EVMS configuration file (evms.conf). This file contains settings to control how EVMS operates.
For example, the logging level, the location of the engine
log, and the list of disk devices to examine can all be
controlled through settings in the configuration file.
The sample file is well commented and advises you of appropriate
values for each setting.
The evms.conf file is normally installed in
/etc/evms.conf. However, if you already have a configuration
file, it is installed as /etc/evms.conf.sample. Examine the
new sample
to see if your existing file should be updated.
You can now begin using EVMS by typing evmsgui
to start the GUI, evmsn to
start the Ncurses UI, or evms to start the
command line interpreter.
2.7.2. Installing the EVMS Debian packages
Debian packages of EVMS are maintained by Matt Zimmerman
at the Debian website.
You can download these packages for the Woody
(testing) release, or for the
Sid (unstable) release.
For the Debian package, patch and recompile your kernel in order to use
EVMS. Debian has a packaged version of the EVMS kernel patches
that includes instructions for patching and building your kernel.
2.7.3. Installing from CVS
If you would like to use the most recently developed version of EVMS, you can get
the code directly from the CVS tree.
To download the code, type the
following commands:
mkdir /usr/src/evms_cvs
cd /usr/src/evms_cvs
cvs -d:pserver:[email protected]:/cvsroot/evms login
(press Enter when prompted for a password)
cvs -z3 -d:pserver:[email protected]:/cvsroot/evms co engine2 |
Alternatively, if you already have a copy of the CVS code checked out, you can update
to the latest code with the following commands:
cd /usr/src/evms_cvs/engine2
cvs update -d -P |
The EVMS Engine can be built directly into the CVS tree. To start, change
directory to /usr/src/evms_cvs/engine2:
cd /usr/src/evms_cvs/engine2
autoconf |
| NOTE |
|---|
| | The autoconf command is necessary only for code taken directly from CVS. |
Select the appropriate options for your configuration.
| NOTE |
|---|
| | You can find the list of options by typing:
|
Configure your engine:
Type the following commands:
make
make install
ldconfig |
Unless you specified other directories in Step 5, the
following list describes where files are installed
on your system:
The core Engine library is installed in
/lib.
The core dlist library is installed in
/lib.
All plug-in libraries is installed in
/lib/evms.
All user interface binaries are installed
in /sbin.
All header files are installed in
/usr/include/evms.
All manual pages are installed in /usr/man.
Add the Engine library path to your
LD_LIBRARY_PATH environment variable, or to
your /etc/ld.so.conf file. Do not add the
plug-in library path because the Engine dynamically loads
these libraries directly.
