1、装依赖
yum install -y java-1.8.0-openjdk
2、安装elasticsearch
-
目录创建 mkdir -p /opt/{soft,conf,logs,scripts};mkdir -p /data0/elasticsearch
-
文件解压缩 tar xzvf elasticsearch-5.6.3.tar.gz -C /opt/soft/
-
建立软连接 ln -s /opt/soft/elasticsearch-5.6.3 /opt/soft/elasticsearch
-
添加elastic 用户 adduser elastic -d /opt/soft/elasticsearch -s /sbin/nologin
-
权限赋予 chown -R elastic.elastic /opt/soft/elasticsearch; chown -R elastic.elastic /data0/elasticsearch
3、配置文件修改

3.1.1 #vi /etc/security/limits.conf
追加如下内容
