How to Change the Port Number for SunPlex Manager

If the default port number (3000) conflicts with another running process, change the port number of SunPlex Manager on each node of the cluster.

Note - The port number must be identical on all nodes of the cluster.

1. Open the /opt/SUNWscvw/conf/httpd.conf configuration file using a text editor.

2. Change the Port number entry.

   The Port entry is located under Section 2, 'Main' server configuration.

3. Edit the VirtualHost entry to reflect the new port number.

   The <VirtualHost _default_:3000> entry is located in the section titled "SSL Virtual Host Context".

4. Save the configuration file and exit the editor.

5. Restart SunPlex Manager.

   # /opt/SUNWscvw/bin/apachectl restart

   
   

6. Repeat this procedure on each node of the cluster.

How to Change the Server Address for SunPlex Manager

If you change the hostname of a cluster node, you must change the address from which SunPlex Manager runs. Because the default security certificate is generated based on the node's hostname at the time SunPlex Manager is installed, you must remove one of the SunPlex Manager installation packages and reinstall it. You must complete this procedure on any node that has had its host name changed.

1. Make the Sun Cluster CD-ROM image available to the node.

2. Remove the SUNWscvw package.

   # pkgrm SUNWscvw

   
   

3. Re-install the SUNWscvw package.

   # cd <path to CD-ROM image>/SunCluster_3_1_u1/Packages # pkgadd -d . SUNWscvw

   
   

How to Configure a New Security Certificate

You can generate your own security certificate to enable secure administration of your cluster, and then configure SunPlex Manager to use that certificate instead of the one generated by default. This procedure is an example of how to configure SunPlex Manager to use a security certificate generated by a particular security package. The actual tasks you must complete depend on the security package you use.

Note - You must generate an unencrypted certificate to allow the server to start on its own during booting. Once you have generated a new certificate for each node of your cluster, configure SunPlex Manager to use those certificates. Each node must have its own security certificate.

1. Copy the appropriate certificate to the node.

2. Open the /opt/SUNWscvw/conf/httpd.conf configuration file for editing.

3. Edit the following entry to enable SunPlex Manager to use the new certificate.

   SSLCertificateFile <path to certificate file>

   
   

4. If the server private key is not combined with the certificate, edit the SSLCertificateKeyFile entry.

   SSLCertificateKeyFile <path to server key>

   
   

5. Save the file and exit the editor.

6. Restart SunPlex Manager.

   # /opt/SUNWscvw/bin/apachectl restart

   
   

7. Repeat this procedure for each node in the cluster.

Example--Configuring SunPlex Manager to Use a New Security Certificate

The following example shows how to edit the SunPlex Manager configuration file to use a new security certificate.

[Copy the appropriate security certificates to each node.]
[Edit the configuration file.]
# vi /opt/SUNWscvw/conf/httpd.conf
[Edit the appropriate entries.]
SSLCertificateFile /opt/SUNWscvw/conf/ssl/phys-schost-1.crt
SSLCertificateKeyFile /opt/SUNWscvw/conf/ssl/phys-schost-1.key
[Save the file and exit the editor.]
[Restart SunPlex Manager.]
# /opt/SUNWscvw/bin/apachectl restart

Launching the SunPlex Manager Software

The SunPlex Manager graphical user interface (GUI) provides an easy way to administer some aspects of the Sun Cluster software. See the SunPlex Manager online help for more information.

How to Launch SunPlex Manager

Follow this procedure to start SunPlex Manager on your cluster.

1. Do you intend to access SunPlex Manager by using the cluster node root user name and password rather than set up a different user name and password?

   • If yes, go to Step 5.

   • If no, go to Step 3 to set up SunPlex Manager user accounts.

2. Become superuser on a cluster node.

3. Create a user account to access the cluster through SunPlex Manager.

   You use the useradd(1M) command to add a user account to the system. You must set up at least one user account to access SunPlex Manager if you do not use the root system account. SunPlex Manager user accounts are used only by SunPlex Manager. They do not correspond to any Solaris system user accounts. Creating and assigning an RBAC role to a user account is described in more detail in Creating and Assigning an RBAC Role With a Sun Cluster Management Rights Profile.

   ---

   Note - Users who do not have a user account set up on a particular node cannot access the cluster through SunPlex Manager from that node, nor can users manage that node through another cluster node to which the users do have access.

   ---

4. (Optional) Repeat Step 3 to set up additional user accounts.

5. From the administrative console or any other machine outside the cluster, launch a browser.

6. Disable the browser's Web proxy.

   SunPlex Manager functionality is incompatible with Web proxies.

7. Ensure that the browser's disk and memory cache sizes are set to a value that is greater than 0.

8. From the browser, connect to the SunPlex Manager port on one node of the cluster.

   The default port number is 3000.
