Cassandra不会在linux中作为服务启动

Question

我有一个在Google计算机上运行的debian linux映像.可以成功地让cassandra使用"sudo cassandra"或"sudo cassandra -f",但是一旦我注销这个停止工作.但是,当我尝试将其作为服务运行时,它根本就没有说什么,也没有启动它!我使用aptget包v2.1安装它.

我尝试过sudo服务cassandra启动.看起来它做了什么,然后退出没有任何日志.

请帮我把它作为一项服务来运行.当我将其作为服务运行时,我甚至无法找到日志的存储位置.

我最近遇到了这个问题,而BrianC表示它可能是一个内存不足的情况.在我的情况下,我可以成功启动cassandra sudo cassandra -f但不是/etc/init.d/cassandra start.

对我来说,/var/log/cassandra/system.log作为服务启动时的最后一个日志条目是:

事后没有.如果是内存问题,您应该能够在syslog中验证这一点.如果包含如下内容:

Apr 30 10:53:39 dev kernel: [1173246.957818] Out of memory: Kill process 8229 (java) score 132 or sacrifice child

增加你的公羊.在我的情况下,我增加到2GB,它开始很好.
