ElasticSearch5.2.2 安裝(老版本)

https://www.elastic.co/downloads/elasticsearch
ElasticSearch是一個高可擴展的開源的全文搜索分析引擎。
它容許你快速的存儲、搜索和分析大量數據。ElasticSearch一般做爲後端程序，爲須要複雜查詢的應用提供服務。

檢查 JDK版本
java -version  #確保是 1.7版本以上

下載解壓並建立數據和log目錄
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.2.2.tar.gz
tar -zxvf elasticsearch-5.2.2.tar.gz
cp -R /root/elasticsearch-5.2.2 /usr/local/elasticsearch

mkdir  -p /opt/elasticsearch/{data,logs}

配置es參數文件
vim /usr/local/elasticsearch/config/elasticsearch.yml
  http.port: 9200
  node.name: node-1
  cluster.name: es_cluster
  network.host: 172.31.107.59
  bootstrap.memory_lock: false
  bootstrap.system_call_filter: false
  path.data: /opt/elasticsearch/data
  path.logs: /opt/elasticsearch/logs

配置參數的冒號先後切記要加空格，不然會報錯。

配置環境變量
export ES_HOME=/usr/local/elasticsearch
source /etc/profile

添加獨立用戶---不要在root 用戶下啓動，不支持root  用戶
groupadd elsearch
useradd elsearch -g elsearch
chown -R elsearch:elsearch /usr/local/elasticsearch
chown -R elsearch:elsearch /opt/elasticsearch

設置OS環境
vim /etc/security/limits.conf
 *  soft nofile 65536
 *  hard nofile 131072
 *  soft nproc 2048
 *  hard nproc4096

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

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

最後執行 
sysctl -p

設置防火牆
iptables -I  INPUT -p tcp  --dport 9200 -j ACCEPT
iptables -I  INPUT -p tcp  --dport 9300 -j ACCEPT
service iptables save

 

.啓動

cd ../bin

//直接啓動ElasticSearch
./elasticsearch 

//或者使用後臺方式進行啓動
./elasticsearch -d

查看端口占用

netstat -anp|grep 9200 或lsof -i:9200 //看該進程是否正常運行

啓動elasticsearch服務
sudo su elsearch
cd /usr/local/elasticsearch/bin
./elasticsearch -d -p pid
