ERROR: [1] bootstrap checks failed [1]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
解决：
在宿主机执行：
sysctl -w vm.max_map_count=262144
原因：
vm.max_map_count参数，是允许一个进程在VMAs拥有最大数量（VMA：虚拟内存地址， 一个连续的虚拟地址空间），当进程占用内存超过时， 直接OOM。
elasticsearch占用内存较高。官方要求max_map_count需要配置到最小262144。
问题
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/software/temp/elasticsearch-6.2.2/hs_err_pid1912.log
解决：
内存不够，购买阿里云的机器可以动态增加内存，或者启动时候现在内存为256M
