x-pack是elasticsearch的一个扩展包，将安全，警告，监视，图形和报告功能捆绑在一个易于安装的软件包中，也是官方推荐的。
1.关闭ElasticSearch服务
需要关闭Elasticsearch 服务，如果已经启动的话，则安装安装x-pack失败。
2、ElasticSearch5.x安装x-pack
安装过程中遇到选项直接Y过去就可以了
代码语言：javascript复制[elastic@node1 elasticsearch-5.6.5]$ bin/elasticsearch-plugin install x-pack
-> Downloading x-pack from elastic

默认用户名和密码如下：
用户名：elastic 密码：changeme
5、修改elasticsearch密码
可以直接在Kibana中执行
代码语言：javascript复制PUT _xpack/security/user/elastic/_password
{
"password": "elastic"
}
然后Kibana跳转到登录页面，用新密码登录Kibana即可。
