Question

我更改了Cassandra配置文件

cat /etc/cassandra/cassandra.yaml | grep -n 'seed'
416:seed_provider:
423:          # seeds is actually a comma-delimited list of addresses.
425:          - seeds:"84.208.89.132,192.168.0.23,192.168.0.25,192.168.0.28"

以及群集名称

10:cluster_name: 'Petter Cluster'

我很惊讶看到system.log显示了什么

如何解决此问题？如何在更改后初始化系统？

您似乎遇到了群集名称的问题，如果您愿意更改它，则应该在所有节点上进行更改。

以下是更改群集名称的说明： 1.登录cqlsh 2. cqlsh＆gt; UPDATE system.local SET cluster_name ='Petter Cluster'，其中key ='local'; （您需要在要更改群集名称的每个节点上发出此命令。） system.local仅在本地更改 3. cqlsh＆gt;出口; 4. $ nodetool flush系统 5.将cassandra.yaml群集名称编辑为YOUR_CLUSTER_NAME。 6.重新启动cassandra。
