Elasticsearch6.6部署

1.下载软件

mkdir -p /data/soft
[root@db-01 /data/soft]# ll -h
total 268M
-rw-r--r-- 1 root root 109M Feb 25 2019 Elasticsearch-6.6.0.rpm
-rw-r--r-- 1 root root 159M Sep 2 16:35 jdk-8u102-Linux-x64.rpm

ps:这两个rpm包可以在下方云盘下载

2.安装jdk

rpm -ivh jdk-8u102-linux-x64.rpm 
java -version

3.安装ES

rpm -ivh elasticsearch-6.6.0.rpm

4.检查(内存要大于1G，默认配置占用内存1G空间，否则无法启动)

systemctl daemon-reload
systemctl enable elasticsearch.service
systemctl start elasticsearch.service
systemctl status elasticsearch.service

netstat -lntup|grep 9200
[root@db01 /data/soft]#netstat -lntup|grep 9200
tcp6       0      0 10.0.0.51:9200          :::*                    LISTEN      10489/java

[root@db-01 ~]# curl 127.0.0.1:9200

5.Elasticsearch有哪些重要配置

[root@db01 ~]# rpm -qc elasticsearch
/etc/elasticsearch/elasticsearch.yml #主配置文件
/etc/elasticsearch/jvm.options #JVM虚拟机配置
/etc/init.d/elasticsearch #init启动文件
/etc/sysconfig/elasticsearch #环境变量相关配置
/usr/lib/sysctl.d/elasticsearch.conf #环境变量相关配置
/usr/lib/systemd/system/elasticsearch.service #systemc启动文件
