elasticsearch6.2和logstash启动出现的错误

elasticsearch6.2启动失败，出现如下提示：

1、Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00000000c5330000, 986513408, 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 986513408 bytes for committing reserved memory.
# An error report file with more information is saved as:
# /usr/local/elasticsearch/hs_err_pid1675.log

由于elasticsearch6.2默认分配jvm空间大小为1g，我的阿里云服务器内存不够大，修改jvm空间分配

[python]  view plain  copy

1. # vim config/jvm.options
