当前版本：cassandra2.2.3

1、修改配置文件安全机制: ./conf/cassandra.yaml

authenticator: AllowAllAuthenticator > authenticator: PasswordAuthenticator

2、登录cassandra创建用户(系统默认用户：cassandra/cassandra)

./bin/cqlsh -ucassandra -pcassandra

CREATE USER myusername WITH PASSWORD 'mypassword' SUPERUSER ;

exit;

3、使用新用户登录

./bin/cqlsh -umyusername -pmypassword

备注：删除默认帐号

DROP USER cassandra ;
