无法在Ubuntu 18.04上重新安装Cassandra

我刚刚安装了一个标准版本的Ubuntu 18.04,想把它用作Cassandra节点。

我按照以下步骤安装了卡桑德拉:

##
## Install java 1.8
sudo apt install openjdk-8-jre -y
##
## Check java version
java -version
##
## Create the JAVA_HOME link
echo "JAVA_HOME=$(readlink -f /usr/bin/java | sed "s:bin/java::")" | sudo tee -a /etc/profile
source /etc/profile
echo $JAVA_HOME
##
## Create the Apache Cassandra 3.11.x apt repo:
echo "deb http://www.apache.org/dist/cassandra/debian 311x main" | sudo tee -a /etc/apt/sources.list.d/cassandra.sources.list
curl https://www.apache.org/dist/cassandra/KEYS | sudo apt-key add -
sudo apt-get update
##
## If GPG public key error
sudo apt-key adv --keyserver pool.sks-keyservers.net --recv-key A278B781FE4B2BDA
sudo apt-get update
##
## Install cassandra
sudo apt-get install cassandra
##
## Service status
sudo service cassandra status

输出:

cassandra.service - LSB: distributed storage system for structured data
Loaded: loaded (/etc/init.d/cassandra; generated)
Active: active (exited) since Thu 2018-08-02 23:03:47 UTC; 4h 2min ago
 Docs: man:systemd-sysv-generator(8)
Tasks: 0 (limit: 4662)
CGroup: /system.slice/cassandra.service

“积极(退出)”部分让我觉得事情出了问题。

我想再试一次,然后卸载卡桑德拉:

sudo apt-get remove cassandra
sudo apt-get purge "cassandra-*"
sudo rm -rf /var/lib/cassandra
sudo rm -rf /var/log/cassandra
sudo rm -rf /etc/cassandra
sudo apt-get update

执行了相同的安装步骤,现在/etc/cassandra只包含/triggers/,所有配置文件都丢失了。

我想我还没有完全清理干净
