cassandra centos 6.4错误

我正在安装卡桑德拉。服务器CentOS 6.4版。 我跟踪了税务网站 当我上传命令nodetool status时，服务cassandra无错误启动

我犯了这个错误：

Error: The node does not have system_traces yet, probably still bootstrapping

对于cqlsh：

Connection error: {'127.0.0.1': error (111, "Tried connecting to [('127.0.0.1', 9042)] Last error: Connection refused"

这是卡桑德拉日志中的错误：

是否已安装jna？如yum install jna中所示？执行yum install jna

程序包jna-3.2.4-2.el6.x86_64时是无事可做

是否已安装jna？如在yum install jna中一样？是，当我执行yum install jna时

包jna-3.2.4-2.el6.x86_64已安装且最新版本无事可做

与该错误无关-它无法初始化jna库…最可能的问题是临时文件夹中的exec权限不相关由于该错误，它无法初始化JNA库…很可能是临时文件夹中的exec权限问题
