我已经试着在debian buster上安装cassandra好几个小时了。有很多很多事情我不明白。事实上，没有什么是有效的。在任性的java和随心所欲的cassandra之间，我迷失了方向。
例如，以下命令对cassandra没有任何影响（但它们在这里给出：http://cassandra.apache.org/download/):

sudo service cassandra start
sudo service cassandra start
systemctl stop cassandra
systemctl start cassandra
systemctl restart cassandra
systemctl reload cassandra

没有“kill”命令无法停止：

kill $(ps aux | grep 'cassandra' | awk '{print $2}')

因此，我不知道如何更改配置，即使在重启机器之后，conf也没有应用，cassandra崩溃了。
我想在prod中使用cassandra，但我不太确定？
我的java：

$ java -version
openjdk version "1.8.0_242"
OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_242-b08)
OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.242-b08, mixed mode)

错误将以“cassandra-f”开头：

修复方式：rm-rf/var/lib/cassandra//var/log/cassandra/
但2分钟后：

同龄人倒了，但不是停止服务的理由吗？如果？
java=？？？？⚰️
