本地解析

vi /etc/hosts

scp /etc/hosts es-2:/etc/hosts

scp /etc/hosts es-3:/etc/hosts

 yum -y install wget

安装配置jdk

wget 8u191

scp -3

tar xf jdk-8u191-linux-x64.tar.gz -C /usr/local/

[root@es-1 ~]# vim /etc/profile
JAVA_HOME=/usr/local/java
PATH=$JAVA_HOME/bin:$PATH
export JAVA_HOME PATH
[root@es-1~]# source /etc/profile

安装配置ES

useradd elsearch

ssh es-2 useradd elsearch

ssh es-3 useradd elsearch

echo "123456" | passwd --stdin "elsearch"

wget els包

vim /usr/local/elasticsearch/config/elasticsearch.yml

创建ES数据及日志存储目录

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

scp /usr/local/elasticsearch/config/elasticsearch.yml es-3:/usr/local/elasticsearch/config/elasticsearch.yml 

修改安装目录及存储目录权限

系统优化
