1. Modify vi /etc/security/limits.conf file, increase the allocation

* soft nproc 4096
* hard nproc 4096
4. Modify /etc/sysctl.conf file, increase the allocation
vm.max_map_count=262144
或者
vm.max_map_count=655360
Run sysctl -p take effect
5. Add items arranged in elasticsearch.yml
bootstrap.memory_lock: false
bootstrap.system_call_filter: false
6, the modified configuration item elasticsearch.yml
