在5.0版本之后不支持直接把插件包放入es安裝目錄的plugin目錄下,需要單獨安裝;而且支持在線安裝的插件很少,很多都是需要離線安裝。以前的plugin變為elasticsearch-plugin
獲取在線安裝的插件:
./elasticsearch-plugin install -h Install a plugin The following official plugins may be installed by name: analysis-icu analysis-kuromoji analysis-nori analysis-phonetic analysis-smartcn analysis-stempel analysis-ukrainian discovery-azure-classic discovery-ec2 discovery-gce ingest-attachment mapper-annotated-text mapper-murmur3 mapper-size repository-azure repository-gcs repository-hdfs repository-s3 store-smb transport-nio
接下來我們介紹幾款常用插件的安裝:
head插件
1.安裝環境支持,需要安裝nodejs
yum install -y nodejs npm
2.下載head插件
cd /usr/local/ git clone git://github.com/mobz/elasticsearch-head.git
3.安裝依賴包
cd /usr/local/elasticsearch-head
npm install
#執行后會生成node_modules文件夾
如果遇到異常cnpm不是內部或外部命令 cnpm: command not found,則運行如下腳本,使用淘寶鏡像包
npm install cnpm -g --registry=https://registry.npm.taobao.org cnpm install
修改配置文件
2.修改Gruntfile.js
cd elasticsearch-head
cd /usr/local/elasticsearch-head
vim Gruntfile.js
在該文件中添加如下,務必注意不要漏了添加“,”號,這邊的hostname:’*’,表示允許所有IP可以訪問,此處也可以修改端口號
server: { options: { hostname: '*', port: 9100, base: '.', keepalive: true } }
3.修改elasticsearch-head默認連接地址
cd _site
vi app.js
做如下修改,將ip地址修改為對應的服務器的ip地址
將localhost修改為elasticSearch IP
this.base_uri = this.config.base_uri || this.prefs.get("app-base_uri") || "http://10.0.0.11:9200";
4.修改elasticSearch配置文件並啟動ElasticSearch
這邊需要修改elasticsearch的配置文件elasticsearch.yml,以允許跨域訪問,在文末追加如下代碼即可
http.cors.enabled: true http.cors.allow-origin: "*"
5.修改完畢后重新啟動ElasticSearch(注意不能使用root權限啟動)
6.啟動elasticsearch-head
cd /usr/local/elasticsearch-head
nohup ./node_modules/grunt/bin/grunt server &
訪問10.0.0.11:9100就能看到我們集群信息
一鍵腳本:
vim head_install.sh
#!/bin/sh work_dir=/usr/local node=`ip a s eth0|awk -F"[ /]+" 'NR==3{print $3}'` yum install -y nodejs npm cd ${work_dir} git clone git://github.com/mobz/elasticsearch-head.git cd elasticsearch-head npm install sed -ri.bak "s/9100,/9100\,\n hostname: \'\*\'\,/" Gruntfile.js cd _site sed -ri.bak "s/localhost/${node}/" app.js cat <<EOF >/root/head_start.sh #!/bin/sh work_dir=${work_dir} { while true do n=\$(ps -ef|grep -c [g]runt) if [ \$n -eq 0 ];then cd \${work_dir}/elasticsearch-head nohup ./node_modules/grunt/bin/grunt server & fi sleep 60s done }& EOF chmod +x /root/head_start.sh /root/head_start.sh
Bigdesk插件
1、下載
cd /usr/local/ git clone https://github.com/hlstudio/bigdesk
2、啟動web服務器,默認監聽端口號8000,指定啟動端口,並后台啟動
cd /usr/local/bigdesk/_site nohup python -m SimpleHTTPServer &
此時通過訪問web界面來監控我們的集群狀態。
http://10.0.0.11:8000
cerebro插件
1、下載cerebro插件:
git項目:https://github.com/lmenezes/cerebro/releases
wget https://github.com/lmenezes/cerebro/releases/download/v0.8.3/cerebro-0.8.3.tgz
2、上傳到安裝目錄、解壓:
tar xf cerebro-0.8.3.tgz -C /usr/local/src/ ln -s /usr/local/src/cerebro-0.8.3 /usr/local/cerebro
3、啟動cerebro
cd /usr/local/cerebro nohup ./bin/cerebro &
4、瀏覽器訪問10.0.0.11:9000
連接集群http://10.0.0.11:9000
就能看到數據分片信息。
