When you initially create a BOINC project using
|
||
|
|
<a href=make_project.php>make_project</a>,
|
||
|
|
everything runs on a single host:
|
||
|
|
web server, scheduling server, daemons, tasks, database server,
|
||
|
|
file upload handler.
|
||
|
|
|
||
|
|
<p>
|
||
|
|
You can increase the capacity of your server by spreading
|
||
|
|
these tasks across different hosts.
|
||
|
|
The following rules apply:
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li> The hosts should share a common network file system,
|
||
|
|
and path of the project directory, on any host,
|
||
|
|
should map to the same place.
|
||
|
|
(Exception: the database server can run anywhere).
|
||
|
|
|
||
|
|
<li> The <a href=groups.php>project admin account</a>
|
||
|
|
should exist on all hosts,
|
||
|
|
and that user should be able to use 'ssh' to run
|
||
|
|
commands on any other host without typing a password.
|
||
|
|
|
||
|
|
<li> One host is designated as the project's <b>main host</b>
|
||
|
|
in config.xml.
|
||
|
|
<b>The 'start', 'stop', and 'status' scripts should normally
|
||
|
|
be run on the main host</b>
|
||
|
|
(if you run them on a different host X,
|
||
|
|
they'll affect only daemons and tasks on host X).
|
||
|
|
|
||
|
|
<li> The project admin account on all hosts must be
|
||
|
|
able to access the project's MySQL database.
|
||
|
|
(Exception: data servers and file upload handlers
|
||
|
|
don't need DB access).
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
Host locations are specified as follows:
|
||
|
|
<ul>
|
||
|
|
<li> Scheduling servers are listed in the project's
|
||
|
|
<a href=server_components.php>master page</a>.
|
||
|
|
<li> The hosts on which tasks and daemons are run
|
||
|
|
are specified in the <a href=configuration.php>config.xml</a> file.
|
||
|
|
<li> Data servers are listed in
|
||
|
|
<a href=tools_work.php#wu_template>workunit template files</a>.
|
||
|
|
<li> File upload handlers are listed in
|
||
|
|
<a href=tools_work.php#result_template>result template files</a>.
|
||
|
|
<li> Your web server runs on the host to which your project URL is mapped.
|
||
|
|
</ul>
