启动Cassandra 3.4时出错

Question

I have installed the Cassandra from the main website. I keep on getting an error each time I try to start it

Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00007f85b2000000, 33554432, 0) failed; error='Cannot allocate memory' (errno=12)

There is insufficient memory for the Java Runtime Environment to continue. Native memory allocation (mmap) failed to map 33554432 bytes for committing reserved memory.

An error report file with more information is saved as: /root/hs_err_pid6951.log

The error in the log says

由于内存不足，Cassandra无法启动。您的系统没有足够的内存来满足Cassandra的要求。
