接続性の検証¶
次に進む前に、インターネットへの接続性とノード間の通信を検証することを推奨します。
コントローラー ノードから、インターネットへのアクセスをテストします。
# ping -c 4 docs.openstack.org PING files02.openstack.org (23.253.125.17) 56(84) bytes of data. 64 bytes from files02.openstack.org (23.253.125.17): icmp_seq=1 ttl=43 time=125 ms 64 bytes from files02.openstack.org (23.253.125.17): icmp_seq=2 ttl=43 time=125 ms 64 bytes from files02.openstack.org (23.253.125.17): icmp_seq=3 ttl=43 time=125 ms 64 bytes from files02.openstack.org (23.253.125.17): icmp_seq=4 ttl=43 time=125 ms --- files02.openstack.org ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3004ms rtt min/avg/max/mdev = 125.192/125.282/125.399/0.441 ms
コントローラー ノードから、コンピュート ノードの管理インターフェースへのアクセスをテストします。

コンピュート ノードから、インターネットへのアクセスをテストします。

コンピュート ノードから、コントローラー ノードの管理インターフェースへのアクセスをテストします。

RHEL, CentOS and SUSE distributions enable a restrictive firewall by default. During the installation process, certain steps will fail unless you alter or disable the firewall. For more information about securing your environment, refer to the OpenStack Security Guide.
Ubuntu does not enable a restrictive firewall by default. For more information about securing your environment, refer to the OpenStack Security Guide.
