1、can not run elasticsearch as root
切换到非root用户
groupadd elasticsearch
useradd -g elasticsearch elasticsearch
passwd elasticsearch
2.main ERROR Could not register mbeans java.security.AccessControlException: access denied ("javax.management.MBeanTrustPermission" "register")
改变elasticsearch文件夹所有者到当前用户
sudo chown -R elasticsearch:elasticsearch elasticsearch
3.[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]
[2]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
vim /etc/security/limits.conf
添加下面配置
* soft nofile 65536
* hard nofile 131071
* soft nproc 65536
* hard nproc 65536
vim /etc/sysctl.conf
添加下面配置：
vm.max_map_count=655360
如果后启动的节点加入不到集群中，是因为复制elasticsearch整个文件夹到另一个虚拟机了，此时删除elasticsearch文件夹下的打他里的内容即可
