系统：centos7
es版本：elasticsearch-7.17.6
后台启动：./elasticsearch -d

1.There is insufficient memory for the Java Runtime Environment to continue.

Exception in thread "main" java.lang.RuntimeException: starting java failed with [1]
output:
#

原因：JVM所需内存不足

解决：修改/home/elk/elastic/elasticsearch-7.17.6/config/jvm.options修改内存

原因：被其它进程占用。可能是之前的es启动后没有彻底的关闭

解决：查询并关闭，然后重启

ps aux | grep elasticsearch

kill -9 [pid]

其它：关闭后发现再次执行
发现有一条类似信息如下：

lvyq      17712  17107  0 10:26 pts/1    00:00:00 grep --color=auto elasticsearch

这个进程是当前这条命令的，不是真正的es进程，不用理会
