环境

10.0.0.53 |
条件
1.恢复快照，基础优化
2.每台elasticsearch服务器需要配置2G内存
以下以db01为例进行配置
服务器时间同步
[root@db01 ~]# yum install -y ntpdate
[root@db01 ~]# ntpdate time1.aliyun.com
服务器统一字符集
服务器编码解码的字符集统一使用utf-8
安装Java环境
#上传
[root@db01 ~]# rz jdk-8u181-linux-x64.rpm
#安装
[root@db01 ~]# rpm -ivh jdk-8u181-linux-x64.rpm
安装ES
1.上传或下载包
[root@db01 ~]# rz elasticsearch-6.6.0.rpm
2.安装
[root@db01 ~]# rpm -ivh elasticsearch-6.6.0.rpm
3.根据提示继续操作
[root@db01 ~]# systemctl daemon-reload
[root@db01 ~]# systemctl enable elasticsearch.service
[root@db01 ~]# systemctl start elasticsearch.service
4.验证，es启动过程有点慢，看情况判断
[root@db01 ~]# netstat -lntp
tcp6 0 0 127.0.0.1:9200 :::* LISTEN 20040/java
tcp6 0 0 127.0.0.1:9300 :::* LISTEN 20040/java
[root@db01 ~]# curl 127.0.0.1:9200
{
"name" : "FIddisT",
"cluster_name" : "elasticsearch", #集群的名字
"cluster_uuid" : "m8Y9neWHRxat7V1tVijMxA",
"version" : {
"number" : "6.6.0",
"build_flavor" : "default",
"build_type" : "rpm",
"build_hash" : "a9861f4",
"build_date" : "2019-01-24T11:27:09.439740Z",
"build_snapshot" : false,
"lucene_version" : "7.6.0",
"minimum_wire_compatibility_version" : "5.6.0",
"minimum_index_compatibility_version" : "5.0.0"
},
"tagline" : "You Know, for Search"
}
#es服务启动较慢，可以使用ps或者free -m 判断服务是否运行
配置ES
#db01配置
[root@db01 ~]# vim /etc/elasticsearch/elasticsearch.yml
cluster.name: my-application
node.name: node-51
path.data: /service/es/data
path.logs: /service/es/logs
bootstrap.memory_lock: true
network.host: 10.0.0.51,127.0.0.1
http.port: 9200
discovery.zen.ping.unicast.hosts: ["10.0.0.51", "10.0.0.52","10.0.0.53"]
discovery.zen.minimum_master_nodes: 2
#db02配置
[root@db02 ~]# vim /etc/elasticsearch/elasticsearch.yml
cluster.name: my-application
node.name: node-52
path.data: /service/es/data
path.logs: /service/es/logs
bootstrap.memory_lock: true
network.host: 10.0.0.52,127.0.0.1
http.port: 9200
discovery.zen.ping.unicast.hosts: ["10.0.0.51", "10.0.0.52","10.0.0.53"]
discovery.zen.minimum_master_nodes: 2
#db03配置
[root@db03 ~]# vim /etc/elasticsearch/elasticsearch.yml
cluster.name: my-application
node.name: node-53
path.data: /service/es/data
path.logs: /service/es/logs
bootstrap.memory_lock: true
network.host: 10.0.0.53,127.0.0.1
http.port: 9200
discovery.zen.ping.unicast.hosts: ["10.0.0.51", "10.0.0.52","10.0.0.53"]
discovery.zen.minimum_master_nodes: 2
根据配置文件创建目录
#创建数据目录和日志目录
[root@db01 ~]# mkdir /service/es/{data,logs} -p
#授权
[root@db01 ~]# chown -R elasticsearch.elasticsearch /service/es/
配置启动文件中的内存锁
[root@db01 ~]# vim /usr/lib/systemd/system/elasticsearch.service
[Service]
... ...
LimitMEMLOCK=infinity
重启ES
[root@db01 ~]# systemctl daemon-reload
[root@db01 ~]# systemctl start elasticsearch.service
ES交互
方法一：使用curl命令
#创建索引（库），?pretty以列格式显示
[root@db01 ~]# curl -XPUT '10.0.0.51:9200/student?pretty'
{
"acknowledged" : true,
"shards_acknowledged" : true,
"index" : "student"
}
#添加数据（key value）
[root@db01 ~]# curl -XPUT '10.0.0.51:9200/student/user/1?pretty' -H 'Content-Type: application/json' -d '{"name": "lhd","sex":"man","age":"18","about":"good good study","interests":["chinese","english"]}'
{
"_index" : "student",
"_type" : "user",
"_id" : "1",
"_version" : 1,
"result" : "created",
"_shards" : {
"total" : 2,
"successful" : 1,
"failed" : 0
},
"_seq_no" : 0,
"_primary_term" : 1
}
#查看数据，索引 类型 以列显示
[root@db01 ~]# curl -GET '10.0.0.51:9200/student/user/1?pretty'
{
"_index" : "student",
"_type" : "user",
"_id" : "1",
"_version" : 1,
"_seq_no" : 0,
"_primary_term" : 1,
"found" : true,
"_source" : {
"name" : "lhd",
"sex" : "man",
"age" : "18",
"about" : "good good study",
"interests" : [
"chinese",
"english"
]
}
}
方法二：使用插件1
1.在'电脑上'解压es-head-0.1.4_0.crx.zip，解压到'一个目录'(以后使用浏览器中的插件必须依靠该目录)
2.谷歌浏览器，右上角，三个点或者三个杠
3.更多工具--扩展程序
4.右上角打开开发者模式
5.加载已解压的扩展程序，选择解压问价你的目录
6.右上角有个放大镜或者拼图，点击进去
方法三：使用插件2
#安装npm（只需要在一个节点安装即可，如果前端还有nginx做反向代理可以每个节点都装）
[root@elkstack01 ~]# yum install -y npm
#进入下载head插件代码目录
[root@elkstack01 src]# cd /usr/local/
#从GitHub上克隆代码到本地
[root@elkstack01 local]# git clone git://github.com/mobz/elasticsearch-head.git
#克隆完成后，进入elasticsearch插件目录
[root@elkstack01 local]# cd elasticsearch-head/
#清除缓存
[root@elkstack01 elasticsearch-head]# npm cache clean -f
#使用npm安装n模块（不同的项目js脚本所需的node版本可能不同，所以就需要node版本管理工具）
[root@elkstack01 elasticsearch-head]# npm install -g n
#安装最新版本n模块
[root@elkstack01 elasticsearch-head]# n stable
#生成grunt
[root@elkstack01 elasticsearch-head]# npm install grunt -save
#确认生成grunt文件
[root@elkstack01 elasticsearch-head]# ll node_modules/grunt
#执行安装grunt
[root@elkstack01 elasticsearch-head]# npm install
#后台启动head插件（切记，必须在插件目录下执行启动命令）
[root@elkstack01 elasticsearch-head]# npm run start &
#验证端口是否启动成功
[root@elkstack01 elasticsearch-head]# netstat -lntup
tcp 0 0 0.0.0.0:9100 0.0.0.0:* LISTEN 11293/grunt
#启动成功后，修改elasticsearch配置文件
[root@elkstack01 elasticsearch-head]# vim /etc/elasticsearch/elasticsearch.yml
#添加如下两行，开启跨域访问支持（添加在配置文件最后即可）
http.cors.enabled: true
http.cors.allow-origin: "*"
#重启elasticsearch
[root@elkstack01 elasticsearch-head]# /etc/init.d/elasticsearch restart
