To enable your dCache to run the Webadmin-interface your system has to run
the info service. For the authenticated mode a configured gPlazma is also
required (see also the section called “gPlazma config example to work with authenticated webadmin”).
The KAuth-File has to be on the same machine then the Webadmin for
this to work. For a non-authenticated Webadmin you just need to add the Webadmin
service to a domain and configure the port Webadmin will listen on - webadminHttpPort.
For authenticated mode the host certificate has to be imported into the dCache-keystore. In the grid world host certificates are usually signed by national Grid-CAs. Refer to the documentation provided by the Grid-CA to find out how to request a certificate. To import them into the dCache-keystore use this command:
[root] #/opt/d-cache/bin/dcache import hostcert
Now you have to initialise your truststore (this is the certificate-store used for the SSL connections) by using this command:
[root] #/opt/d-cache/bin/dcache import cacerts
Webadmin-interface uses the same truststore as WebDAV, so maybe you can skip
this step.
You can enable the Webadmin interface by adding the service (Webadmin) to a domain.
Example:
[webadminDomain] [webadminDomain/webadmin] webadminDCacheInstanceName=coolName webadminAuthenticated=true webadminAdminGid=1000
The default value for the webadminHttpsPort
is 8444 and for the
webadminHttpPort it is
8080. Have a look at the following example to
see how to modify these values.
Example:
[webadminDomain] [webadminDomain/webadmin] webadminHttpsPort=8445 webadminHttpPort=8081 webadminDCacheInstanceName=coolName webadminAuthenticated=true webadminAdminGid=1000
The most important value is webadminAdminGid, because it configures who is allowed to
alter dCache behaviour, which certainly should not be everyone:
# ---- GID a user has to have to be considered an Admin of webadmininterface # # When a user has this GID he can become an Admin for webadmininterface webadminAdminGid=1000
To see all webadmin specific property values have a look at
/opt/d-cache/share/defaults/webadmin.properties.
For information on gPlazma configuration have a look at
Chapter 12, Authorization in dCache and for a special example
the section called “gPlazma config example to work with authenticated webadmin”.
After startup of webadmin you can reach it via http://example.com:8080/webadmin.
Since webadmin bases on the info it takes some time until all values are populated,
because info needs to collect them first. It is recommended to let info run on
the same machine then Webadmin.
