1、首先要远程连接就要修改elasticsearch.yml配置文件的network.host

改为 network.host: 192.168.2.14 （自己局域网ip）或者 0.0.0.0

2、如果遇到问题

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

解决办法：切换到root用户，编辑sysctl.conf 

vim /etc/sysctl.conf 

添加下面配置：

vm.max_map_count = 655360

并执行命令：

sudo sysctl -p

3. 如果遇到问题

max file descriptors [4096] for elasticsearch process likely too low, increase to at least [65536]

max number of threads [1024] for user [lishang] likely too low, increase to at least [2048]

解决办法：切换到root用户，编辑limits.conf 添加类似如下内容

vi /etc/security/limits.conf 

 添加如下内容:

* soft nofile 65536
* hard nofile 131072
* soft nproc 2048
* hard nproc 4096

 修改完成一定要退出，再次登录参数才能生效。

4. 如果遇到问题

max number of threads [1024] for user [lish] likely too low, increase to at least [2048]

解决办法：切换到root用户，进入limits.d目录下修改配置文件。

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

 修改如下内容：

* soft nproc 1024

 修改为

* soft nproc 2048

5.如果遇到问题

system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk

解决方法：在elasticsearch.yml中配置bootstrap.system_call_filter为false，注意要在Memory下面:

bootstrap.memory_lock: false
bootstrap.system_call_filter: false

此时重启 elasticsearch就可以通过远程访问了
