Cassandra:无法分配请求的地址

Question

我有datastax-cassandra 1.2.5,我在.yaml文件中有以下设置

• storage_port:7000
• ssl_storage_port:7001
• listen_address:localhost
• rpc_port:9160

我一直这样.我曾尝试更改存储端口一次,但它比同样的东西更有效.我无法再次重启cassandra

最有可能的是网络配置有问题:localhost解析为DHCP分配的无效主机名(如类似192-168-1-10.local)或本地IPv6地址(::1),并且在java中禁用IPv6.

• 校验 /etc/hosts
• 检查hostname命令输出
• 尝试设置listen_address为127.0.0.1有效的IP地址.
• 检查rpc_address设置cassandra.yaml.尝试将其设置为127.0.0.1
