![Cassandra 多节点安装,由于权限被拒绝,无法打开文件 /var/log/cassandra/gc.log](https://linux22.com/image/716712/Cassandra%20%E5%A4%9A%E8%8A%82%E7%82%B9%E5%AE%89%E8%A3%85%EF%BC%8C%E7%94%B1%E4%BA%8E%E6%9D%83%E9%99%90%E8%A2%AB%E6%8B%92%E7%BB%9D%EF%BC%8C%E6%97%A0%E6%B3%95%E6%89%93%E5%BC%80%E6%96%87%E4%BB%B6%20%2Fvar%2Flog%2Fcassandra%2Fgc.log.png)
我想在 4 个远程节点上安装 Cassandra。一切正常,直到我检查状态时才到达
nodetool status
Datacenter: datacenter1
=======================
Status=Up/Down
|/ State=Normal/Leaving/Joining/Moving

我已正确将 listen_address 设置为 192.68.0.25,将 seeds 设置为 192.69.0.13
我在另一个节点上也遇到了同样的问题

这是我从命令 shell 运行 cassandra 时得到的结果

其实我没有gc.log。这是文件夹的内容
/var/log/cassandra$ ls *.log
debug.log system.log
和
/var/log$ ls -lia cassandra/

确保您的 /etc/hosts 文件格式有效,例如
root@my-cass1-1:~# cat /etc/hosts | egrep -v "^#|::"
127.0.0.1 localhost
192.168.xxx.13 my-cass1-1.int.xxxxxxxxx.tld my-cass1-1
其中没有 localhost.localdomain 内容。
在 cassandra.yaml 中设置这两个选项:
root@my-cass1-1:~# cat /etc/cassandra/cassandra.yaml | grep 192.168
- seeds: "192.168.xxx.111,192.168.xxx.112,192.168.xxx.13,192.168.xxx.10"
listen_address: 192.168.xxx.13
broadcast_rpc_address: 192.168.xxx.13
