elasticsearch配置远程连接错误解决办法

 

配置远程访问

network.host: 0.0.0.0

错误如下

ERROR: [4] bootstrap checks failed
[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65535]
[2]: max number of threads [3795] for user [es] is too low, increase to at least [4096]
[3]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
[4]: the default discovery settings are unsuitable for production use; at least one of [discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured

解决办法：

错误一：

vim /etc/security/limits.conf

文件内容追加内容

soft nofile 65536
hard nofile 131072

错误二：

vim /etc/security/limits.conf

文件追加以下内容（如果不对请在每行前面加上为elasticsearch配置的用户）

soft nproc 4096
hard nproc 4096

 错误三：

vim /etc/sysctl.conf

添加一行配置

vm.max_map_count=655360

重启后配置生效 

错误四：

在elasticsearch文件中找到conf文件夹，修改其中的elasticsearch.yml文件

放开：

cluster.initial_master_nodes: ["node-1", "node-2"]

如果端口已经放开，则可以进行远程访问elasticsearch
