安装jdk
安装jdkde要点主要就是环境变量
导出JAVA_HOME
JRE_HOME
导出可执行程序到PATH变量
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=.:$JAVA_HOME/lib.tools.jar" >>/etc/profile
echo "PATH=/usr/local/jdk/bin:/bin:/sbin:/usr/sbin:/bin:/usr/bin:/root/bin" >>/etc/profile
echo "export JAVA_HOME CLASSPATH PATH" >>/etc/profile
source /etc/profile
/usr/local/jdk/bin/java -version
java version "1.8.0_73"
Java(TM) SE Runtime Environment (build 1.8.0_73-b02)
Java HotSpot(TM) 64-Bit Server VM (build 25.73-b02, mixed mode)
2. es安装
1) 将es压缩文件移到/opt中
mv elasticsearch-2.3.3.tar.gz /opt/
2)解压，重命名
tar zxvf elasticsearch-2.3.3.tar.gz
mv elasticsearch-2.3.3 elasticsearch
3)由于ElasticSearch可以接收用户输入的脚本并且执行，为了系统安全考虑， 建议创建一个单独的用户用来运行ElasticSearch
groupadd elsearch
useradd elsearch -g elsearch -p elasticsearch
4)更改elasticsearch文件夹及内部文件的所属用户及组为elsearch:elsearch
cd /opt
chown -R elsearch:elsearch elasticsearch
5)切换到elsearch用户再启动
su elsearch cd elasticsearch/bin
./elasticsearch
6)[elsearch@localhost opt]$ cd elasticsearch/bin/
[elsearch@localhost bin]$ ./elasticsearch

3.怎么确认是否安装成功
在浏览器中输入 http://ip:9200/ 访问，如果无法访问，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 #后台进程启动
再次访问显示如下内容说明成功
