本文介绍了如何解决Cassandra启动过程中遇到的UnknownHostException错误。通过在/etc/hosts文件中添加本机名称，可以有效解决该问题并成功启动Cassandra。

启动Cassandra出现类似：

java.net.UnknownHostException

 

编辑/etc/hosts文件，增加本机名称：

127.0.0.1   localhost HostName
::1         localhost HostName

 

保存后，再次启动Cassandra，成功

1、服务器没网，调不到公网域名，无法解析出IP，从而无法识别host，导致无法连接；第4步：修改hosts文件，把域名和IP写到hosts文件中，用于把域名解析成IP。即使服务器没网，单点登录服务在同一个内网，那么网络也是通的。2、网络端口映射做了策略，调用不到自己路由的域名，必须调内网IP；第6步：完成，这样就可以调到优快云域名下的接口了。，需要在hosts文件中把接口的。写上，在服务器发送求时，就会。第1步：用有互联网的机器。第3步：打开hosts文件。Windows：一般在。域名/IP的映射关系。

这个错误通常在尝试执行`nodetool status`时发生，因为Cassandra节点还没有完全启动完成。从之前的日志看，节点启动过程中存在一些问题（如内存锁定警告和swap未禁用），但最关键的是节点启动过程可能还未完成。 ##...

某业务系统因OS改造，原先的Zabbix监控系统推倒后未重建，本来计划用外部企业内其他监控系统接入，后又通知需要自建才能对接，考虑之前zabbix的一些不便，本次计划采用一个类Prometheus的监控系统，镜调研后发现Nightingale兼容Prometheus，又有一些其他功能增强，又在一些大的企业经过较大规模部署实践，故本次采用Nightingale作为监控系统来进行重建。
