首先，你要有一套es，关于es的部署，可以看我的另一篇博客
ELK-EFK-v7.12.0日志平台部署

$ ./bin/elasticsearch-plugin install x-pack
-> Installing x-pack
-> Failed installing x-pack
ERROR: this distribution of Elasticsearch contains X-Pack by default

这里可以看到，es 7.12版本默认是包含x-pack了，不需要像之前的版本安装了

$ cp config/elasticsearch.yml{,.bak}     '良好的备份习惯，可以有效减少跑路的次数'
$ vim config/elasticsearch.yml           '加入下面的参数，然后重启es'
xpack.security.enabled: true
xpack.security.transport.ssl.enabled: true
xpack.security.transport.ssl.verification_mode: certificate

auto 随机生成一个密码

interactive 自定义密码
