Preparing UNIX for TDV Installation
This section applies only if you are installing TDV on a machine running a supported UNIX operating system. Examples of valid and invalid /etc/hosts file entries are shown in the following table.
|
Validity |
/etc/hosts File Entry |
|
Valid |
127.0.0.1 localhost |
|
Valid |
127.0.0.1 localhost localhost.localdomain |
|
Valid |
127.0.0.1 localhost localhost.localdomain localhost |
|
Invalid |
127.0.0.1 localhost.localdomain |
|
Invalid |
127.0.0.1 localhost.localdomain localhost |
To prepare your UNIX machine for installation of TDV products
| 1. | Review the new features and bug fixes as documented in the TDV and Business Directory Release Notes. |
| 2. | Run the following command to determine if localhost can be resolved on the target installation machine before attempting an installation: |
ping localhost
| 3. | If the ping results look like the following, localhost is being resolved and the machine is ready for TDV installation. You can continue with the instructions in other sections. |
Linux Ping Example with Valid localhost
$ ping localhost
PING localhost (127.0.0.1) from 127.0.0.1 : 56(84) bytes of data.
64 bytes from localhost (127.0.0.1): icmp_seq=1 ttl=255 time=0.071 ms
64 bytes from localhost (127.0.0.1): icmp_seq=2 ttl=255 time=0.063 ms
64 bytes from localhost (127.0.0.1): icmp_seq=3 ttl=255 time=0.043 ms
--- localhost ping statistics ---
3 packets transmitted, 3 received, 0% loss, time 1999ms
rtt min/avg/max/mdev = 0.043/0.059/0.071/0.011 ms
| 4. | If the ping results look like the following, localhost is not correct. You must edit your /etc/hosts file. |
Linux Ping Example with Invalid localhost
This example of /etc/hosts files shows where Server is unable to connect to the repository database because of the localhost.localdomain entry preceding the localhost entry (assuming the localhost entry exists at all).
$ ping localhost
PING localhost.localdomain (127.0.0.1) from 127.0.0.1 : 56(84) bytes of data.
64 bytes from localhost.localdomain (127.0.0.1): icmp_seq=1 ttl=255 time=0.080 ms
64 bytes from localhost.localdomain (127.0.0.1): icmp_seq=2 ttl=255 time=0.071 ms
64 bytes from localhost.localdomain (127.0.0.1): icmp_seq=3 ttl=255 time=0.044 ms
--- localhost.localdomain ping statistics ---
3 packets transmitted, 3 received, 0% loss, time 1998ms
rtt min/avg/max/mdev = 0.044/0.065/0.080/0.015 ms
| 5. | Edit the /etc/hosts file to add a localhost entry, directly after the 127.0.0.1 entry, with the following syntax: |
127.0.0.1 localhost <optional host name>
| 6. | Save your changes and rerun the ping for localhost. |
