通过ES_HOME/bin/x-pack/certgen生成ssl证书
[elasticsearch@elasticsearch elasticsearch-6.0.0]$ ./bin/x-pack/certgen
This tool assists you in the generation of X.509 certificates and certificate
signing requests for use with SSL in the Elastic stack. Depending on the command
line option specified, you may be prompted for the following:

* The path to the output file
    * The output file is a zip file containing the signed certificates and
      private keys for each instance. If a Certificate Authority was generated,
      the certificate and private key will also be included in the output file.
* Information about each instance
    * An instance is any piece of the Elastic Stack that requires a SSL certificate.
      Depending on your configuration, Elasticsearch, Logstash, Kibana, and Beats
      may all require a certificate and private key.
    * The minimum required value for each instance is a name. This can simply be the
      hostname, which will be used as the Common Name of the certificate. A full
      distinguished name may also be used.
    * A filename value may be required for each instance. This is necessary when the
      name would result in an invalid file or directory name. The name provided here
      is used as the directory name (within the zip) and the prefix for the key and
      certificate files. The filename is required if you are prompted and the name
      is not displayed in the prompt.
    * IP addresses and DNS names are optional. Multiple values can be specified as a
      comma separated string. If no IP addresses or DNS names are provided, you may
      disable hostname verification in your SSL configuration.
* Certificate Authority private key password
    * The password may be left empty if desired.

Let's get started...

Please enter the desired output file [certificate-bundle.zip]: 
Enter instance name: elasticsearch
Enter name for directories and files [elasticsearch]: 
Enter IP Addresses for instance (comma-separated if more than one) []: 127.0.0.1,10.59.30.96,10.59.30.97
Enter DNS names for instance (comma-separated if more than one) []: elasticsearch,elasticsearch-1,elasticsearch-2
Would you like to specify another instance? Press 'y' to continue entering instance information: 
Certificates written to /home/elasticsearch/software/elasticsearch-6.0.0/certificate-bundle.zip

This file should be properly secured as it contains the private keys for all
instances and the certificate authority.

After unzipping the file, there will be a directory for each instance containing
the certificate and private key. Copy the certificate, key, and CA certificate
to the configuration directory of the Elastic product that they will be used for
and follow the SSL configuration instructions in the product guide.

For client applications, you may only need to copy the CA certificate and
configure the client to trust this certificate.

修改账户密码

修改密码需使用超级管理员权限即elastic账户，接口为POST _xpack/security/user/<username>/_password
curl参数含义如下
-XPOST 使用post方法传递参数
-H 指定http协议的header信息
-u 指定用于认证的用户信息用户名与密码使用冒号分隔
-d 指定具体要传递的参数信息
[elasticsearch@elasticsearch elasticsearch-6.0.0]$ curl -XPOST -H 'Content-type: application/json' -u elastic:elastic 'http://10.59.30.96:9200/_xpack/security/user/kibana/_password?pretty' -d '{"password": "123456"}'
{ }
密码修改后使用老密码访问则返回401，使用更新后的密码则正常
