安装版本：7.14.2

基础环境安装

JDK安装

安装es的机器都需要安装

JDK版本11

• 将安装包移动到/opt目录下

tar -zxvf jdk-11.0.17_linux-x64_bin.tar.gz 

• JDK加入环境变量

  修改/etc/profile，在尾部添加

  export JAVA_HOME=/opt/jdk-11.0.17
  export PATH=$PATH:$JAVA_HOME/bin
  

修改Linux配置

* hard memlock unlimited
* soft memlock unlimited

• 在/etc/sysctl.conf文件最后添加一行

vm.max_map_count=262144

执行

sysctl -p

• 修改 /etc/systemd/system.conf

vi /etc/systemd/system.conf
DefaultLimitMEMLOCK=infinity

安装ES

需要安装es的集群都要执行以下步骤

• 将安装包移动到/opt目录

mv elasticsearch-7.14.2-linux-x86_64.tar.gz /opt

• 修改ES使用内存

修改配置文件config/jvm.options

################################################################
## IMPORTANT: JVM heap size
################################################################
##
## The heap size is automatically configured by Elasticsearch
## based on the available memory in your system and the roles
## each node is configured to fulfill. If specifying heap is
## required, it should be done through a file in jvm.options.d,
## and the min and max should be set to the same value. For
## example, to set the heap to 4 GB, create a new file in the
## jvm.options.d directory containing these lines:
##
## -Xms4g
## -Xmx4g
##
## See https://www.elastic.co/guide/en/elasticsearch/reference/current/heap-size.html
## for more information

• 创建elasticsearch用户

useradd elasticsearch
passwd elasticsearch

• 修改目录权限

chown elasticsearch.elasticsearch -R /opt/elasticsearch-7.14.2

• 切换用户启动es

su elasticsearch
cd /opt/elasticsearch-7.14.2

• 生成CA证书

bin/elasticsearch-certutil ca
warning: usage of JAVA_HOME is deprecated, use ES_JAVA_HOME
This tool assists you in the generation of X.509 certificates and certificate
signing requests for use with SSL/TLS in the Elastic stack.

The 'ca' mode generates a new 'certificate authority'
This will create a new X.509 certificate and private key that can be used
to sign certificate when running in 'cert' mode.

Use the 'ca-dn' option if you wish to configure the 'distinguished name'
of the certificate authority

By default the 'ca' mode produces a single PKCS#12 output file which holds:
    * The CA certificate
    * The CA's private key

If you elect to generate PEM format certificates (the -pem option), then the output will
be a zip file containing individual files for the CA certificate and private key

Please enter the desired output file [elastic-stack-ca.p12]:  #直接回车即可,不用设置密码
Enter password for elastic-stack-ca.p12 : #直接回车即可,不用设置密码

在当前目录可以看到 elastic-stack-ca.p12文件

• 生成密钥

bin/elasticsearch-certutil cert --ca elastic-stack-ca.p12
warning: usage of JAVA_HOME is deprecated, use ES_JAVA_HOME
This tool assists you in the generation of X.509 certificates and certificate
signing requests for use with SSL/TLS in the Elastic stack.

The 'cert' mode generates X.509 certificate and private keys.
    * By default, this generates a single certificate and key for use
       on a single instance.
    * The '-multiple' option will prompt you to enter details for multiple
       instances and will generate a certificate and key for each one
    * The '-in' option allows for the certificate generation to be automated by describing
       the details of each instance in a YAML file

    * An instance is any piece of the Elastic Stack that requires an 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.

    * All certificates generated by this tool will be signed by a certificate authority (CA)
      unless the --self-signed command line option is specified.
      The tool can automatically generate a new CA for you, or you can provide your own with
      the --ca or --ca-cert command line options.

By default the 'cert' mode produces a single PKCS#12 output file which holds:
    * The instance certificate
    * The private key for the instance certificate
    * The CA certificate

If you specify any of the following options:
    * -pem (PEM formatted output)
    * -keep-ca-key (retain generated CA key)
    * -multiple (generate multiple certificates)
    * -in (generate certificates from an input file)
then the output will be be a zip file containing individual certificate/key files

Enter password for CA (elastic-stack-ca.p12) : # 直接回车
Please enter the desired output file [elastic-certificates.p12]: # 直接回车
Enter password for elastic-certificates.p12 : # 直接回车

Certificates written to /opt/elasticsearch-7.14.2/elastic-certificates.p12

This file should be properly secured as it contains the private key for 
your instance.

This file is a self contained file and can be copied and used 'as is'
For each Elastic product that you wish to configure, you should copy
this '.p12' file to the relevant configuration directory
and then 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.

在当前目录会生成elastic-certificates.p12文件

• 证书移动到指定目录

# 在config目录下创建certs
mkdir config/certs
# 证书移动到certs目录
 mv elastic-certificates.p12 config/certs/

• 后台启动es

cd /opt/elasticsearch-7.14.2
bin/elasticsearch -d

• 设置密码

这里可以复制输入
