默认情况下,Elastic 只允许本机访问,如果需要远程访问,可以修改 Elastic 安装目录的config/elasticsearch.yml
文件,去掉network.host
的注释,将它的值改成0.0.0.0
,然后重新启动 Elastic。
network.host: 0.0.0.0
上面代码中,设成0.0.0.0
让任何人都可以访问。线上服务不要这样设置,要设成具体的 IP。
启动失败,检查没有通过,报错

编辑 /etc/security/limits.conf,追加以下内容;
* soft nofile 65536
* hard nofile 65536
此文件修改后需要重新登录用户,才会生效

编辑 /etc/sysctl.conf,追加以下内容:

保存后,执行:

重新启动,成功。
