elasticsearch异常问题 discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured
阅读原文时间:2023年07月10日阅读:4

再次启动,又出错了:

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

我们用的是新创建的用户,而不是root,所以文件权限不足。

首先用root用户登录。

然后修改配置文件:

vim /etc/security/limits.conf

添加下面的内容:

* soft nofile 65536

* hard nofile 131072

* soft nproc 4096

* hard nproc 4096

刚才报错中,还有一行:

[1]: max number of threads [1024] for user [leyou] is too low, increase to at least [4096]

这是线程数不够。

继续修改配置:

vim /etc/security/limits.d/20-nproc.conf

修改下面的内容:

* soft nproc 1024

改为:

* soft nproc 4096

vm.max_map_count:限制一个进程可以拥有的VMA(虚拟内存区域)的数量,继续修改配置文件, :

vim /etc/sysctl.conf

添加下面内容:

vm.max_map_count=655360

然后执行命令:

sysctl -p

修改conf-->elasticsearch.yml

elasticsearch.yml文件

node.name: node-1 前面的#打开

#network.host: 192.168.0.1
network.host: 192.168.136.110
#network.host: 0.0.0.0
#network.host: localhost
#network.host: 127.0.0.1 这里把network.host 设置为自己的ip地址 也可以设置成0.0.0.0(代表所有ip可以访问)

cluster.initial_master_nodes: ["node-1"] 这里一定要这样设置,我就是这里没有这样设置出问题的,弄了好久
这里的 node-1 是上面node.name:后面的对应值

在最后加上这两句,要不然,外面浏览器就访问不了哈

http.cors.enabled: true
http.cors.allow-origin: "*"
