环境

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.rpm2.安装[root@db01 ~]# rpm -ivh elasticsearch-6.6.0.rpm3.根据提示继续操作[root@db01 ~]# systemctl daemon-reload[root@db01 ~]# systemctl enable elasticsearch.service[root@db01 ~]# systemctl start elasticsearch.service4.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/javatcp6       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.ymlcluster.name: my-applicationnode.name: node-51path.data: /service/es/datapath.logs: /service/es/logsbootstrap.memory_lock: truenetwork.host: 10.0.0.51,127.0.0.1http.port: 9200discovery.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.ymlcluster.name: my-applicationnode.name: node-52path.data: /service/es/datapath.logs: /service/es/logsbootstrap.memory_lock: truenetwork.host: 10.0.0.52,127.0.0.1http.port: 9200discovery.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.ymlcluster.name: my-applicationnode.name: node-53path.data: /service/es/datapath.logs: /service/es/logsbootstrap.memory_lock: truenetwork.host: 10.0.0.53,127.0.0.1http.port: 9200discovery.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 -lntuptcp        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: truehttp.cors.allow-origin: "*"#重启elasticsearch[root@elkstack01 elasticsearch-head]# /etc/init.d/elasticsearch restart
