ProcedureTo Configure the Kickstart File

Steps

  1. Log in to a machine that is accessible to the management server using NFS or HTTP.

  2. Create the Linux Kickstart configuration file.

    Choose whether to use the entire distribution Kickstart file shown in Example 3–2, or the required-RPMs-only Kickstart file shown in Example 3–3. Copy the chosen configuration data into a file, for example, n1gc-ks.cfg

    Note –

    If you chose the required-RPMs-Kickstart file, you must also manually install additional RPMs as described by To Install RPMs Required by the Sun N1 System Manager From the CD-ROMs.

  3. Configure the Kickstart installation file for your environment.

    • If you plan to use dynamic IP addressing, replace each network statement in the Kickstart file using the following syntax:

      network --device ethx --bootproto dhcp

      where ethx is the port, for example, eth0.

    • If you plan to use static IP addressing, make the following changes in each of the network statements.

      • Replace ip with the Ethernet port IP address.

      • Replace nameserver with the IP address of the corporate name server. If you want to use more than one name server, separate each name server IP address with a comma. For example: --nameserver 110.112.113.11,110.112.113.22.

      • Replace hostname with the name of your management server.

      If desired, you can combine static and dynamic IP addressing for the ETH ports. Modify the network settings according to your chosen reference architecture.

  4. Save the Kickstart file to an NFS or HTTP directory on the Kickstart server.

ProcedureTo Enable FTP on a Linux Based Management Server

Steps

  1. Log in to the management server as root.

  2. Create symbolic links to the /etc/init.d/vsftpd file in the /etc/rc3.d and /etc/rc5.d directories.

    For example:


    # ln -s /etc/init.d/vsftpd /etc/rc3.d/S99vsftpd
# ln -s /etc/init.d/vsftpd /etc/rc5.d/S99vsftpd

    The FTP service is enabled, and starts when the management server is rebooted. After the system is rebooted, you can verify whether the FTP service has start using the ps and grep commands:


    # ps -eaf | grep ftp
root    3035    1  0  16:27 ?    00:00:00 /usr/sbin/vsftpd /etc/vsftpd/vsf
Next Steps

Update the /etc/hosts file as described in Updating the /etc/hosts File.

Updating the /etc/hosts File

The IP address and the name of your management server must be added to the /etc/hosts. Failure to add the IP address and name will cause Sun N1 System Manager installation to fail.

ProcedureTo Update the /etc/hosts file

Steps

  1. Log in as root to the Sun N1 System Manager management server.

  2. Verify that the /etc/hosts file has entries for loopback and the server.

    1. Make certain that either of the following loopback entries is in the /etc/hosts file.

      127.0.0.1    localhost

      or

      127.0.0.1    localhost.localdomain    localhost

    2. Make certain that an entry exists for the server and its IP address. For example:

      111.11.111.11 n1mgmt

      where 111.11.111.11 is the IP address of the management server, and n1mgmt is the name of the management server.

      Your /etc/hosts should be similar to the following example:

      127.0.0.1    localhost.localdomain    localhost
10.5.157.123 n1mgmt

    3. Save and close /etc/hosts.

  3. Reboot the N1 System Manager management server.
