Centos7.4 安装elasticsearch6.1.3集群部署

安装elasticsearch

1.依赖环境安装

这里使用的java 是1.8.0_77的版本.使用的是rpm 安装包的形式进行部署安装 。

配置环境变量

[root@node1 ~]# cat .bash_profileexport JAVA_HOME=/usr/java/jdk1.8.0_77/                     # JAVA_HOME变两个路径export JAVA_BIN=/usr/java/jdk1.8.0_77/binexport PATH=${JAVA_HOME}bin:$PATH 

检测java环境安装是否正常

[root@node1 ~]# java -versionjava version "1.8.0_77"Java(TM) SE Runtime Environment (build 1.8.0_77-b03)Java HotSpot(TM) 64-Bit Server VM (build 25.77-b03, mixed mode)

2.elasticsearch使用的是6.1.3版本。elasticsearch-6.1.3.tar.gz

[root@node1 local]# tar -zxvf elasticsearch-6.1.3.tar.gz  [root@node1 local]# lsbin  elasticsearch-6.1.3  elasticsearch-6.1.3.tar.gz  etc  games  include  lib  lib64  libexec  sbin  share  src

修改配置文件

node1[root@node1 local]# cd   node1/config/[root@node1 config]# cat elasticsearch.yml | grep -v "^#"cluster.name: elasticsearch #集群的名称node.name: node1   #节点的名称bootstrap.memory_lock: false #另一种选择是在Linux / Unix系统上使用mlockall或在Windows上使用            VirtualLock，以尝试将进程地址空间锁定到RAM中，防止任何Elasticsearch           内存被换出。bootstrap.system_call_filter: false #为禁用系统调用过滤器falsenetwork.host: 133.1.11.39   #绑定到回送地址 

http.port: 9200    #设置对外服务的http端口，默认为9200discovery.zen.ping.unicast.hosts: ["133.1.11.39","133.1.11.39:9202","133.1.11.39:9203"]discovery.zen.minimum_master_nodes: 2

node2cluster.name: elasticsearchnode.name: node2bootstrap.memory_lock: falsebootstrap.system_call_filter: false network.host: 133.1.11.39

http.port: 9202discovery.zen.ping.unicast.hosts: ["133.1.11.39","133.1.11.39:9202","133.1.11.39:9203"]discovery.zen.minimum_master_nodes: 2 

node3cluster.name: elasticsearchnode.name: node3bootstrap.memory_lock: falsebootstrap.system_call_filter: false network.host: 133.1.11.39

[root@node1 config]# vim jvm.options -Xms512m-Xmx512m

3.需要修改的配置参数

vim /etc/security/limits.conf* soft nofile 65536* hard nofile 131072* soft nproc 2048* hard nproc 4096

vim /etc/security/limits.d/90-nproc.conf* soft nproc 2048

vim /etc/sysctl.conf vm.max_map_count=655360sysctl -p

4.启动elasticsearch 不能使用root 用户需要进行创建用户

[root@node1 ~]# groupadd es[root@node1 ~]# useradd es -g es -p es[root@node1 ~]# chown -R es:es /usr/local/node1

启动elasticsearch

[root@node1 bin]# ./elasticsearch -d

5.进行访问测试

[root@node1 bin]# curl  http://133.1.11.39:9200{  "name" : "node1",  "cluster_name" : "elasticsearch",  "cluster_uuid" : "dJo2cKFfSO-M-qwMF9upjg",  "version" : {    "number" : "6.1.3",    "build_hash" : "af51318",    "build_date" : "2018-01-26T18:22:55.523Z",    "build_snapshot" : false,    "lucene_version" : "7.1.0",    "minimum_wire_compatibility_version" : "5.6.0",    "minimum_index_compatibility_version" : "5.0.0"  },  "tagline" : "You Know, for Search"}

安装head 插件

1.安装NodeJS

[root@node1 ~]# wget https://npm.taobao.org/mirrors/node/latest-v4.x/node-v4.5.0-linux-x64.tar.gz[root@node1 ~]#tar -zxvf  node-v4.5.0-linux-x64.tar.gz -C /usr/local

配置环境变量export NODE_HOME=/usr/local/node-v4.5.0-linux-x64export PATH=$PATH:$NODE_HOME/bin/export NODE_PATH=$NODE_HOME/lib/node_modules[root@node1 ~]#source /etc/profile

2.安装npm

[root@node1 ~]#  npm install -g cnpm --registry=https://registry.npm.taobao.org

3.使用npm安装grunt

/usr/local/node-v4.5.0-linux-x64/bin/grunt -> /usr/local/node-v4.5.0-linux-x64/lib/node_modules/grunt/bin/gruntgrunt@1.0.2 /usr/local/node-v4.5.0-linux-x64/lib/node_modules/grunt├── path-is-absolute@1.0.1├── eventemitter2@0.4.14├── grunt-known-options@1.1.0├── rimraf@2.2.8├── exit@0.1.2├── iconv-lite@0.4.19├── coffeescript@1.10.0├── nopt@3.0.6 (abbrev@1.1.1)├── glob@7.0.6 (inherits@2.0.3, fs.realpath@1.0.0, once@1.4.0, inflight@1.0.6)├── findup-sync@0.3.0 (glob@5.0.15)├── minimatch@3.0.4 (brace-expansion@1.1.11)├── grunt-cli@1.2.0 (resolve@1.1.7)├── js-yaml@3.5.5 (esprima@2.7.3, argparse@1.0.10)├── grunt-legacy-util@1.0.0 (getobject@0.1.0, async@1.5.2, hooker@0.2.3, underscore.string@3.2.3, which@1.2.14, lodash@4.3.0)├── grunt-legacy-log@1.0.1 (hooker@0.2.3, colors@1.1.2, underscore.string@3.3.4, grunt-legacy-log-utils@1.0.0, lodash@4.17.5)└── dateformat@1.0.12 (get-stdin@4.0.1, meow@3.7.0)

[root@node1 ~]#  npm install -g grunt-cli --registry=https://registry.npm.taobao.org --no-proxy/usr/local/node-v4.5.0-linux-x64/bin/grunt -> /usr/local/node-v4.5.0-linux-x64/lib/node_modules/grunt-cli/bin/gruntgrunt-cli@1.2.0 /usr/local/node-v4.5.0-linux-x64/lib/node_modules/grunt-cli├── grunt-known-options@1.1.0├── nopt@3.0.6 (abbrev@1.1.1)├── resolve@1.1.7└── findup-sync@0.3.0 (glob@5.0.15 

4.版本确认

[root@node1 ~]# node -vv4.5.0[root@node1 ~]# npm -v2.15.9[root@node1 ~]#  grunt -versiongrunt-cli v1.2.0

5.下载head插件源码

[root@node1 ~]#  wget https://github.com/mobz/elasticsearch-head/archive/master.zip[root@node1 ~]# unzip master.zip  -d /usr/local/

6.下载依赖

[root@node1 elasticsearch-head-master]# npm install -g grunt-cli /usr/local/node-v4.5.0-linux-x64/bin/grunt -> /usr/local/node-v4.5.0-linux-x64/lib/node_modules/grunt-cli/bin/gruntgrunt-cli@1.2.0 /usr/local/node-v4.5.0-linux-x64/lib/node_modules/grunt-cli├── grunt-known-options@1.1.0├── resolve@1.1.7├── nopt@3.0.6 (abbrev@1.1.1)└── findup-sync@0.3.0 (glob@5.0.15)

[root@node1 elasticsearch-head-master]#  grunt -versiongrunt-cli v1.2.0[root@node1 elasticsearch-head-master]# npm install

二. 配置ElasticSearch

停止ElasticSearch

[root@node1 local]# jps28516 Jps12072 Elasticsearch

1.配置 ElasticSearch，使得HTTP对外提供服务

node1 上面配置[root@node1 ]# vim config/elasticsearch.yml# 增加新的参数，这样head插件可以访问es。设置参数的时候:后面要有空格http.cors.enabled: truehttp.cors.allow-origin: "*"

2.修改head插件配置文件

[root@node1 elasticsearch-head-master]# vim Gruntfile.js connect: {                        server: {                                options: {                                        hostname: '0.0.0.0',                                        port: 9100,                                        base: '.',                                        keepalive: true                                }                        }                }   修改修改连接地址：_site/app.js[root@node1 elasticsearch-head-master]# vim _site/app.js    _node_handler: function(data) {                        if(data) {//                              this.prefs.set("app-base_uri", this.cluster.base_uri);                                this.prefs.set("app-base_uri" )|| "http://133.1.11.39:9200";                                if(data.version && data.version.number)                                        this.cluster.setVersion(data.version.number);

3.启动elasticsearch,head

[root@node1 bin]# ./elasticsearch -d #分别启动3个节点[root@node1 elasticsearch-head-master]# nohup  grunt  server &

4.注意坑

如果出现集群无法链接请注意删除node1 下面/usr/local/node1/data 下面的目录，不然造成数据不统一 不能呢链接head 插件
