ES的单机多实例伪集群安装

ES的单机多实例伪集群安装

ES的单机多实例伪集群安装和单机单实例安装整体过程大致一样，可参考如下博客：

下面内容主要描述关键点

1.copy多个ES文件夹

如下图，在es目录下方三个es的安装目录，每个目录即一个es实例

2.修改每个es实例的配置文件

实例1
/opt/bigdata/es/elasticsearch_01/config/elasticsearch.yml

cluster.name: SOC
node.name: node-1
node.master: true
node.data: true
path.data: /data/es/data/node-1
path.logs: /data/es/logs/node-1
network.host: 0.0.0.0
http.port: 9200
transport.tcp.port: 9300
discovery.seed_hosts: ["10.220.186.175:9300","10.220.186.175:9301","10.220.186:9302"]
cluster.initial_master_nodes: ["node-1", "node-2", "node-3"]

实例2
/opt/bigdata/es/elasticsearch_02/config/elasticsearch.yml

cluster.name: SOC
node.name: node-2
node.master: true
node.data: true
path.data: /data/es/data/node-2
path.logs: /data/es/logs/node-2
network.host: 0.0.0.0
http.port: 9201
transport.tcp.port: 9301
discovery.seed_hosts: ["10.220.186.175:9300","10.220.186.175:9301","10.220.186:9302"]
cluster.initial_master_nodes: ["node-1", "node-2", "node-3"]

实例3
/opt/bigdata/es/elasticsearch_03/config/elasticsearch.yml

cluster.name: SOC
node.name: node-3
node.master: true
node.data: true
path.data: /data/es/data/node-3
path.logs: /data/es/logs/node-3
network.host: 0.0.0.0
http.port: 9202
transport.tcp.port: 9302
discovery.seed_hosts: ["10.220.186.175:9300","10.220.186.175:9301","10.220.186:9302"]
cluster.initial_master_nodes: ["node-1", "node-2", "node-3"]

说明：

1.保证cluster.name一致，三个实例即可加入到同一个集群
2.保证三个节点/实例分别用不同的http.port和transport.tcp.port
3.path.data和path.logs可以提前手动创建好，并chown其属主属组为es

3.分别启动每个ES节点/实例即可
