Below are the configuration changes you need to make on cassandra.yaml file

First Node
--------------
listen_address: 192.168.1.143 <span class="token punctuation">(</span>This should be your server/node IP<span class="token punctuation">)</span>
seeds: <span class="token string">"192.168.1.143"</span> <span class="token punctuation">(</span>For your first node please mention your node IP address<span class="token punctuation">)</span>

Second Node
---------------
listen_address: 192.168.1.144 <span class="token punctuation">(</span>This should be your server/node IP<span class="token punctuation">)</span>
seeds: <span class="token string">"192.168.1.143"</span> <span class="token punctuation">(</span>specify your first node IP, additionally, you can also mention current IP address ,192.168.1.144<span class="token punctuation">)</span>

Third Node
---------------
listen_address: 192.168.1.145 <span class="token punctuation">(</span>This should be your server/node IP<span class="token punctuation">)</span>
seeds: <span class="token string">"192.168.1.143"</span> <span class="token punctuation">(</span>specify your first/second node IP, additionally, you can also mention current IP address ,192.168.1.145<span class="token punctuation">)</span>

After starting cassandra on all 3 servers, nodetool status returned the following
