安装elasticsearch很简单,基本上不需要怎么安装,下载压缩包解压后,进入目录直接在bash中运行bin/目录下的elasticsearch即可启动一个elasticsearch服务。
配置集群需要修改config目录下的elasticsearch.yml文件;
设置集群的名称,master和slave 都设置成同一个名称,才能组成集群
给当前节点指定一个名称,我取名为master,并且设置node.master 为 true
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
#cluster.name: my-application
# 集群名称
cluster.name: seagm
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
#node.name: node-1
# master名称
node.name: master
node.master: true
#
# Add custom attributes to the node:
#
#node.attr.rack: r1
#
把IP绑定为127.0.0.1
elasticsearch的默认端口是 9200, 这里我暂不修改。等会儿slave中需要修改,因为slave和master放在同一台电脑上不能同时使用9200
# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
#network.host: 192.168.0.1
network.host: 127.0.0.1
#
# Set a custom port for HTTP:
#
#http.port: 9200
#
# For more information, consult the network module documentation.
#
# ---------------------------------- Various -----------------------------------
#
# Require explicit names when deleting indices:
#
#action.destructive_requires_name: true
http.cors.enabled: true
http.cors.allow-origin: "*"
以上是master的配置 配置好后,bash运行./bin/elasticsearch 然后稍后片刻,等elasticsearch运行之后,可在流览器中输入localhost:9200 看到如下输出
{
"name" : "master",
"cluster_name" : "seagm",
"cluster_uuid" : "WmBVxtB-QsqsRQK_Srkijg",
"version" : {
"number" : "6.4.2",
"build_flavor" : "default",
"build_type" : "tar",
"build_hash" : "04711c2",
"build_date" : "2018-09-26T13:34:09.098244Z",
"build_snapshot" : false,
"lucene_version" : "7.4.0",
"minimum_wire_compatibility_version" : "5.6.0",
"minimum_index_compatibility_version" : "5.0.0"
},
"tagline" : "You Know, for Search"
}
cluster.name: seagm
node.name: slave1
network.host: 127.0.0.1
http.port: 8200
discovery.zen.ping.unicast.hosts: ["127.0.0.1"]
- 指定cluster.name 与上面的主节点cluster.name相同(这个是必须的)
- 指定node.name 为slave1(这个可以随便取)
- network.host 需要与主节点绑定的ip相同
- http.port: 这个需要重指定一个端口号,原因上面已经说了
- 最后那一句。。忘了是什么意思了..
- 总之,这样配置好后,就可以通过./bin/elasticsearch启动这个slave1了。
启动之后,可以在浏览器中单独访问这个节点localhost:8200,可以看到输出:
{
"name" : "slave1",
"cluster_name" : "seagm",
"cluster_uuid" : "WmBVxtB-QsqsRQK_Srkijg",
"version" : {
"number" : "6.4.2",
"build_flavor" : "default",
"build_type" : "tar",
"build_hash" : "04711c2",
"build_date" : "2018-09-26T13:34:09.098244Z",
"build_snapshot" : false,
"lucene_version" : "7.4.0",
"minimum_wire_compatibility_version" : "5.6.0",
"minimum_index_compatibility_version" : "5.0.0"
},
"tagline" : "You Know, for Search"
}
访问:localhost:9200/_cat/nodes
