安裝jdk
安裝jdkde要點主要就是環境變量
導出JAVA_HOME
JRE_HOME導出可執行程序到PATH變量
tar -zxvf jdk-8u73-linux-x64.tar.gz
tar -zxf jdk-8u73-linux-x64.tar.gz
mv jdk1.8.0_73 /usr/local/jdk
echo "JAVA_HOME=/usr/local/jdk" >>/etc/profile
echo "CLASSPATH=.:$JAVA_HOME/lib.tools.jar" >>/etc/profile
echo "PATH=/usr/local/jdk/bin:/bin:/sbin:/usr/sbin:/bin:/usr/bin:/root/bin" >>/etc/profile
echo "export JAVA_HOME CLASSPATH PATH" >>/etc/profile
source /etc/profile
/usr/local/jdk/bin/java -version
java version "1.8.0_73"
Java(TM) SE Runtime Environment (build 1.8.0_73-b02)
Java HotSpot(TM) 64-Bit Server VM (build 25.73-b02, mixed mode)
2. es安裝
1) 將es壓縮文件移到/opt中
mv elasticsearch-2.3.3.tar.gz /opt/
2)解壓，重命名
tar zxvf elasticsearch-2.3.3.tar.gz
mv elasticsearch-2.3.3 elasticsearch
3)由於ElasticSearch可以接收用戶輸入的腳本並且執行，爲了系統安全考慮， 建議創建一個單獨的用戶用來運行ElasticSearch
groupadd elsearch
useradd elsearch -g elsearch -p elasticsearch
4)更改elasticsearch文件夾及內部文件的所屬用戶及組爲elsearch:elsearch
cd /opt
chown -R elsearch:elsearch elasticsearch
5)切換到elsearch用戶再啓動
su elsearch cd elasticsearch/bin
./elasticsearch
6)[elsearch@localhost opt]$ cd elasticsearch/bin/
[elsearch@localhost bin]$ ./elasticsearch

3.怎麼確認是否安裝成功
在瀏覽器中輸入 http://ip:9200/ 訪問，如果無法訪問，需要修改配置文件elasticsearch.yml
# vim /usr/local/src/elasticsearch-2.3.3/config/elasticsearch.yml
# Set the bind address to a specific IP (IPv4 or IPv6):
network.host: localhost
# Set a custom port for HTTP:
http.port: 9200
# ./bin/elasticsearch -d #後臺進程啓動
再次訪問顯示如下內容說明成功
