[elasticsearch] 集群搭建

相关内容下载：

1、elasticsearch-6.3.1

2、kibana-6.3.1

1、服务器环境准备

服务器A：公网IP[ip1]，非root用户[elastic1]，运行路径[path1]

服务器B：公网IP[ip2]，非root用户[elastic2]，运行路径[path2]

2、配置文件修改

vi [path1]/elasticsearch-6.3.1/config/elasticsearch.yml

network.host: 0.0.0.0
network.publish_host: [ip1]
discovery.zen.ping.unicast.hosts: ["[ip1]","[ip2]"]
cluster.name: mycluster
node.name: NODE1
node.master: true
node.data: true
discovery.zen.minimum_master_nodes: 1

vi [path2]/elasticsearch-6.3.1/config/elasticsearch.yml

network.host: 0.0.0.0
network.publish_host: [ip2]
discovery.zen.ping.unicast.hosts: ["[ip1]","[ip2]"]
cluster.name: mycluster
node.name: NODE1
node.master: false
node.data: true
discovery.zen.minimum_master_nodes: 1

3、启动elasticsearch

服务器A：

cd [path1]/elasticsearch-6.3.1

./bin/elasticsearch

服务器B：

cd [path2]/elasticsearch-6.3.1

./bin/elasticsearch

4、启动kibana

服务器A：

cd [path1]/kibana-6.3.1-linux-x86_64

./bin/kibana

遇到的问题：

• don’t run elasticsearch as root.

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

• elasticsearch 无法启动直接killed

• Exception in thread “main” java.nio.file.AccessDeniedException

chown -R [用户] ./elasticsearch

• not enough master nodes discovered during pinging (found [[]], but needed [-1]), pinging again

因为使用的是云服务器，有内网ip和外网ip，需要指定配置文件中network.publish_host为外网ip。
