在centos7中安装elasticsearch6.3

Posted 2022-05-27 dhqz

第一：必须要有jre

elasticsearch是用Java实现的，跑elasticsearch必须要有jre支持，所以必须先安装jre

自己百度安装（1.8）

第二：下载elasticsearch

进入官方下载 https://www.elastic.co/downloads/elasticsearch

因为是centos中运行 所以我们选 tar.gz压缩包；

下载后 用ftp上传到centos里 我们把这个文件上传到 /home/data/下

第三：解压

直接启动

sh /opt/module/elasticsearch-6.3.0/bin/elasticsearch

有报错：

解决：

在

这个文件最后面加上bootstrap.system_call_filter: false

重新启动！
