1、安装Java8，检查安装版本:java -version
2、Python 2.7(为了使用 cqlsh).检查安装版本:python -V
3、当前最新版本是3.11.6获取源码包apache-cassandra-3.11.6-bin.tar.gz
4、解压并重命名[root@tomcat-122-12 ~]# tar zxf apache-cassandra-3.11.6-bin.tar.gz[root@tomcat-122-12 ~]# mv apache-cassandra-3.11.6 /usr/local/cassandra[root@tomcat-122-12 ~]#
5、添加环境变量vim /etc/profile export CASSANDRA_HOME=/usr/local/cassandraexport PATH=$CASSANDRA_HOME/bin:$PATHsource /etc/profile
6、创建cassandra用户,所属组为cassandragroupadd cassandrauseradd cassandra -g cassandra
7、切换用户并启动cassandra[root@tomcat-122-12 conf]# chown -R cassandra. /usr/local/cassandra[root@tomcat-122-12 conf]# su - cassandraLast login: Tue May 5 00:48:27 CST 2020 on pts/0[cassandra@tomcat-122-12 ~]$ cassandra -f
8、查看进程ps -ef|grep cassandra
