自己测试服务器

1.配置说明:

系统:centos7 64

内存:1G

2.问题描述:

安装了两个es节点:node1和node2

启动node1之后再启动node2,node1就被干掉

再启动node1,node2就被干掉

...

循环

3.排查问题:

node1 elasticssearch.yml配置:

cluster.name: test

node.name: es-9201

path.data: /opt/elasticsearch/node2/data

path.logs: /opt/elasticsearch/node2/log

node.max\_local\_storage\_nodes: 2

node.master: true

node.data: true

network.host: 192.168.168.161

http.port: 9201

\#culster transport port

bootstrap.memory\_lock: true

bootstrap.system\_call\_filter: false

transport.tcp.port: 9301

transport.tcp.compress: true

discovery.zen.ping.unicast.hosts: \["192.168.168.161:9301","192.168.168.161:9302"\]

discovery.zen.minimum\_master\_nodes: 1

discovery.zen.ping\_timeout: 5s

http.cors.enabled: true

http.cors.allow-origin: "\*"

http.cors.allow-methods: OPTIONS, HEAD, GET, POST, PUT, DELETE

http.cors.allow-headers: Authorization,X-Requested-With,Content-Length,Content-Type

\#script.inline: on

\#script.indexed: on

\#script.search: on

此配置无问题

node2 elasticssearch.yml配置:

cluster.name: test

node.name: es-9202

path.data: /opt/elasticsearch/node2/data

path.logs: /opt/elasticsearch/node2/log

node.max\_local\_storage\_nodes: 2

node.master: true

node.data: true

network.host: 192.168.168.161

http.port: 9202

\#culster transport port

bootstrap.memory\_lock: true

bootstrap.system\_call\_filter: false

transport.tcp.port: 9302

transport.tcp.compress: true

discovery.zen.ping.unicast.hosts: \["192.168.168.161:9301","192.168.168.161:9302"\]

discovery.zen.minimum\_master\_nodes: 1

discovery.zen.ping\_timeout: 5s

http.cors.enabled: true

http.cors.allow-origin: "\*"

http.cors.allow-methods: OPTIONS, HEAD, GET, POST, PUT, DELETE

http.cors.allow-headers: Authorization,X-Requested-With,Content-Length,Content-Type

\#script.inline: on

\#script.indexed: on

\#script.search: on

node1 jvm.option配置

...

\-Xms1024m

\-Xmx1024m

...

node2 jvm.option配置

...

\-Xms1024m

\-Xmx1024m

...

问题出在此处,内存正好设置1G,导致上面的问题

由于主机内存较大,直接将虚拟机内存改为4G,解决问题

如果主机内存较小,可以直接修改jvm.option中上面两个参数的值

例如,可以修改为:

\-Xms128m

\-Xmx128m
