<command>repmgr witness register</command> adds a witness server's node
|
|
record to the &repmgr; metadata, and if necessary initialises the witness
|
|
node by installing the &repmgr; extension and copying the &repmgr; metadata
|
|
to the witness server. This command needs to be executed to enable
|
|
use of the witness server with <application>repmgrd</application>.
|
|
</para>
|

<para>
|
|
When executing <command>repmgr witness register</command>, database connection
|
|
information for the cluster primary server must also be provided.
|
|
</para>
|
|
<para>
|
|
In most cases it's only necessary to provide the primary's hostname with
|
|
the <option>-h</option>/<option>--host</option> option; &repmgr; will
|
|
automatically use the <varname>user</varname> and <varname>dbname</varname>
|
|
values defined in the <varname>conninfo</varname> string defined in the
|
|
witness node's <filename>repmgr.conf</filename>, unless these are explicitly
|
|
provided as command line options.
|
|
</para>
|

<para>
|
|
Execute with the <option>--dry-run</option> option to check what would happen
|
|
without actually registering the witness server.
