elastic IP 重新綁定後無法連接

①编辑$ES_HOEM/config/elasticsearch.yml，修改network.host:为绑定ip。然后重启，报错如下

②[x]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]

vim /etc/security/limits.conf

• soft nproc 65536

• hard nproc 65536

• soft nofile 65536

• hard nofile 65536

③[x]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

vim /etc/sysctl.conf

     vm.max_map_count=262144

保存退出，sysctl -p 不重启使配置生效

④[x]: max number of threads [1024] for user [test] is too low, increase to at least [4096]

vim /etc/security/limits.d/90-nproc.conf

1024 改为4096或者unlimited

⑤[x]: system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk

vim elasticsearch.yml

bootstrap.memory_lock: false

bootstrap.system_call_filter: false

⑥重启使配置生效

reboot & restart elasticsearch
