参考: https://www.jianshu.com/p/cc71e7793f6f

TLS工具安装
- 下载TLS工具 https://repo1.maven.org/maven2/com/floragunn/search-guard-tlstool/1.5/
- 解压unzip search-guard-tlstool-1.6.zip tlstool-1.6

TLS生成证书配置
- 复制<tlstool directory>/config/example.yml 并修改成<tlstool-1.6>/config/tlsconfig.yml(名字随意)
- yibai 是公司名称
- ca: 根证书配置
- node: 节点证书配置
- clients: 客户端证书配置

### Self-generated certificate authority
###
#
# If you want to create a new certificate authority, you must specify its parameters here.
# You can skip this section if you only want to create CSRs
#
ca:
  root:
      # The distinguished name of this CA. You must specify a distinguished name.   
     dn: CN=root.ca.yibai.com,OU=CA,O=yibai Com\, Inc.,DC=yibai,DC=com

      # The size of the generated key in bits
     keysize: 2048

      # The validity of the generated certificate in days from now
     validityDays: 3650
     
      # Password for private key
      #   Possible values:
      #   - auto: automatically generated password, returned in config output; 
      #   - none: unencrypted private key; 
      #   - other values: other values are used directly as password   
     pkPassword: auto
     
      # The name of the generated files can be changed here
     file: root-ca.pem
     
   # If you want to use an intermediate certificate as signing certificate,
   # please specify its parameters here. This is optional. If you remove this section,
   # the root certificate will be used for signing.         
  intermediate:
      # The distinguished name of this CA. You must specify a distinguished name.
     dn: CN=signing.ca.yibai.com,OU=CA,O=yibai Com\, Inc.,DC=yibai,DC=com
  
      # The size of the generated key in bits   
     keysize: 2048
     
      # The validity of the generated certificate in days from now      
     validityDays: 3650
 
     pkPassword: auto
           
      # If you have a certificate revocation list, you can specify its distribution points here      
     crlDistributionPoints: URI:https://raw.githubusercontent.com/floragunncom/unittest-assets/master/revoked.crl

###
### Default values and global settings
###
defaults:

      # The validity of the generated certificate in days from now
     validityDays: 3650
     
      # Password for private key
      #   Possible values:
      #   - auto: automatically generated password, returned in config output;

     pkPassword: auto      
     
      # Specifies to recognize legitimate nodes by the distinguished names
      # of the certificates. This can be a list of DNs, which can contain wildcards.
      # Furthermore, it is possible to specify regular expressions by
      # enclosing the DN in //.
      # Specification of this is optional. The tool will always include
      # the DNs of the nodes specified in the nodes section.            
      #nodesDn:
      #- "CN=*.yibai.com,OU=Ops,O=yibai Com\\, Inc.,DC=yibai,DC=com"

      # - 'CN=elk-devcluster*'
      # - '/CN=.*regex/'

      # If you want to use OIDs to mark legitimate node certificates,
      # the OID can be included in the certificates by specifying the following
      # attribute
     
      # nodeOid: "1.2.3.4.5.5"

      # The length of auto generated passwords            
     generatedPasswordLength: 12
     
      # Set this to true in order to generate config and certificates for
      # the HTTP interface of nodes
     httpsEnabled: true
     
      # Set this to true in order to re-use the node transport certificates
      # for the HTTP interfaces. Only recognized if httpsEnabled is true
     
      # reuseTransportCertificatesForHttp: false
     
      # Set this to true to enable hostname verification
      #verifyHostnames: false
     
      # Set this to true to resolve hostnames
      #resolveHostnames: false

### Nodes
###
#
# Specify the nodes of your ES cluster here
#

TLS生成证书

<tlstool directory>/tools/sgtlstool.sh -c ../config/tlsconfig.yml -ca -crt

复制证书到ES

# 复制节点证书到es配置目录
cp <tlstool directory>/tools/out/<nodename>.pem <ES directory>/config/
cp <tlstool directory>/tools/out/<nodename>.key <ES directory>/config/
cp <tlstool directory>/tools/out/<nodename>_http.pem <ES directory>/config/
cp <tlstool directory>/tools/out/<nodename>_http.key <ES directory>/config/
# 复制根证书到es配置目录
cp <tlstool directory>/tools/out/root-ca.pem <ES directory>/config/
# 复制客户端证书到es配置目录
cp <tlstool directory>/tools/out/spock.pem <ES directory>/config/
cp <tlstool directory>/tools/out/spock.key <ES directory>/config/

修改<ES directory>/config/elasticsearch.yml 复制 <tlstool directory>/tools/outnode3_elasticsearch_config_snippet.yml里面配置信息覆盖<ES directory>/config/elasticsearch.yml相同的配置最终的配置如下:

# 节点名
node.name: node-1

# 数据存储路径

# 日志打印路径
path.logs: /data/es_logs

# Set the bind address to a specific IP (IPv4 or IPv6):
