【elasticSearch 配置用户名密码】

一、设置密码
1.需要在配置文件中开启x-pack验证, 修改config目录下面的elasticsearch.yml文件，在里面添加如下内容,并重启.

xpack.security.enabled: true
xpack.license.self_generated.type: basic
xpack.security.transport.ssl.enabled: true

2，执行设置用户名和密码的命令,这里需要为4个用户分别设置密码，elastic, kibana, logstash_system,beats_system

bin/elasticsearch-setup-passwords interactive

网上设置时出现的：

You will be prompted to enter passwords as the process progresses.
