问题描述
我正在尝试在ubuntu 20.04中安装Apache Cassandra 3，并遵循此处https://linuxize.com/post/how-to-install-apache-cassandra-on-ubuntu-20-04/提供的安装指南。
我安装了Java 11
java --version
java 11.0.8 2020-07-14 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.8+10-LTS)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.8+10-LTS,mixed mode)
并安装了cassandra
sudo apt install cassandra
[sudo] password for kianoosh:

Reading state @R_116_4045@ion... Done
cassandra is already the newest version (3.11.8).
0 upgraded,0 newly installed,0 to remove and 6 not upgraded.
然后我跑步
nodetool status
