How to Set Up An AI Server

Language:

This procedure describes how to set up a server so you can perform automatic installations of Oracle Solaris over the network.

Install Oracle Solaris 11.3.
Although you can install any version of Oracle Solaris 11 on an AI server, the Oracle Solaris 11.3 release includes several server-side enhancements which can only be used if that version is installed on the AI server. If you have an existing Oracle Solaris AI server, see the documentation for that release for AI server configuration instructions. For suggestions on which installation method to use, see Comparing Installation Options.
Become an administrator.
For more information, see Using Your Assigned Administrative Rights in Securing Users and Processes in Oracle Solaris 11.3.

Verify that the network interface IP address is static.

In this example net0 is configured using a static IP address.

# ipadm
NAME              CLASS/TYPE STATE        UNDER      ADDR
net0           ip         ok           --         --
   net0/v4     static     ok           --         192.0.2.5/24
lo0            loopback   ok           --         --
   lo0/v4      static     ok           --         127.0.0.1/24
   lo0/v6      static     ok           --         ::1/128

If the address is not static, follow the steps below.

Create the IP interface.
```
# ipadm create-ip net0
```

Configure a static IP on the interface.

# ipadm create-addr -T static -a local=192.0.2.5/24 net0

Verify configuration.

# ipadm
    NAME      CLASS/TYPE     STATE     UNDER     ADDR
    net0      loopback       ok        --        --
   net0/v4     static    ok        --        192.0.2.5/24

(Optional) Establish a default route for the AI server.
```
# route -p add default 192.0.2.1
```

Install the AI package.

Verify that the AI package is not already installed.

# pkg list installadm
pkg list: no packages matching 'installadm' installed

Verify that your IPS package repository contains the AI package.

# pkg list -a installadm
NAME (PUBLISHER)                            VERSION                  IFO
install/installadm                          0.5.11-0.175.1.0.0.24.0  ---

Install the AI package.

# pkg install install/installadm

Enable multicast DNS (mDNS).
The mDNS service enables AI clients to find replicated install services on other AI servers on the same subnet. For more information about mDNS, see Multicast DNS and Service Discovery in Working With Oracle Solaris 11.3 Directory and Naming Services: DNS and NIS.
1. If needed, install the mDNS package.
```
# pkg install pkg:/service/network/dns/mdns
```
2. Update name service switch information.
  To be able to resolve local hosts, change the config/host property of the name-service/switch service to include mdns as a source. For example:
```
#  /usr/sbin/svccfg -s svc:/system/name-service/switch
svc:/system/name-service/switch> setprop config/host = astring: "files dns mdns"
svc:/system/name-service/switch> select system/name-service/switch:default
svc:/system/name-service/switch:default> refresh
svc:/system/name-service/switch> quit
```
3. Enable the mDNS service.
```
# svcadm enable svc:/network/dns/multicast:default
```
  Enabling mDNS in this way ensures that your changes persist through upgrades and reboots. For more information, see the svcadm(1M) man page.
