Chapter 3. Preparing environment for Satellite Server installation

Procedure

1. Open the ports for clients on Satellite Server:

   # firewall-cmd \
   --add-port="8000/tcp" \
   --add-port="9090/tcp"

2. Allow access to services on Satellite Server:

   # firewall-cmd \
   --add-service=dns \
   --add-service=dhcp \
   --add-service=tftp \
   --add-service=http \
   --add-service=https \
   --add-service=puppetmaster

3. Make the changes persistent:

   # firewall-cmd --runtime-to-permanent

Procedure

1. Ensure that the host name and local host resolve correctly:

   # ping -c1 localhost
   # ping -c1 `hostname -f` # my_system.domain.com

   Successful name resolution results in output similar to the following:

   # ping -c1 localhost
   PING localhost (127.0.0.1) 56(84) bytes of data.
   64 bytes from localhost (127.0.0.1): icmp_seq=1 ttl=64 time=0.043 ms
   
   --- localhost ping statistics ---
   1 packets transmitted, 1 received, 0% packet loss, time 0ms
   rtt min/avg/max/mdev = 0.043/0.043/0.043/0.000 ms
   
   # ping -c1 `hostname -f`
   PING hostname.gateway (XX.XX.XX.XX) 56(84) bytes of data.
   64 bytes from hostname.gateway (XX.XX.XX.XX): icmp_seq=1 ttl=64 time=0.019 ms
   
   --- localhost.gateway ping statistics ---
   1 packets transmitted, 1 received, 0% packet loss, time 0ms
   rtt min/avg/max/mdev = 0.019/0.019/0.019/0.000 ms

2. To avoid discrepancies with static and transient host names, set all the host names on the system by entering the following command:

   # hostnamectl set-hostname name

   Warning

   Name resolution is critical to the operation of Satellite. If Satellite cannot properly resolve its fully qualified domain name, tasks such as content management, subscription management, and provisioning will fail.
