我正在尝试在OS X macbook上设置apache cassandra。我正在尝试测试NoSql数据库，我已经设置了memcached和redis。但是我用cassandra 我正在使用oracle的jdk 1.7.0_09 我遵循了安装说明，但是当我尝试启动服务器时，我从控制台得到了这个问题：

我不知道如何解决这个问题。请帮助我，伙计们：）

3 个答案:

答案 0 :(得分：7)

您无权写入/ var / log，这是预期的。您需要将Cassandra作为sudo运行，或者使用适当的权限自行创建目录。

答案 1 :(得分：4)

config / cassandra.yaml - 包含Cassandra所需的所有文件夹的路径。将这些路径更改为用户具有写入权限的位置，这样您就不需要将其作为sudo运行。

答案 2 :(得分：1)

我认为在本地开发机器上工作的一个可能不那么具有侵入性的解决方案就是根本不搞乱root权限。只需通过编辑<cassandra_install_dir>/conf目录中的log4j属性文件，将日志位置更改为您想要的任何位置。
