es集群配置xpack
一、兼容性检查
1.1 操作系统兼容性
elasticsearch不同版本对操作系统有兼容性要求，可参照如下官方链接查看ES和操作系统兼容需求列表。
产品和操作系统: https://www.elastic.co/cn/support/matrix#matrix_os
1.2 JVM兼容性
elasticsearch不同版本对JVM有兼容性要求，可参照如下官方链接查看ES和JVM兼容需求列表。
产品和JVM: https://www.elastic.co/cn/support/matrix#matrix_jvm
二、环境准备
2.1 环境列表
| 服务器IP | 主机名称 | 角色 | 端口号 | 操作系统版本 |
|---|---|---|---|---|
| 10.110.7.39 | xsky-node1 | master | 9200、9201 | CentOS Linux release 7.9.2009 (Core) |
| 10.110.7.40 | xsky-node2 | master | 9200、9201 | CentOS Linux release 7.9.2009 (Core) |
| 10.110.7.41 | xsky-node3 | master | 9200、9201 | CentOS Linux release 7.9.2009 (Core) |
2.2 关闭防火墙
- -- root 用户执行，所有节点
- systemctl stop firewalld && systemctl disable firewalld
- systemctl status firewalld
2.3 设置内核参数
- -- root 用户执行，所有节点
-
- sed -e '/^vm.max_map_count/d' \
- -i.bak \
- /etc/sysctl.conf; \
- sed -e '$a vm.max_map_count=655360' \
- -i.bak \
- /etc/sysctl.conf; \
- sed -e '/^* soft nofile/d' \
- -e '/^* hard nofile/d' \
- -e '/^elasticsearch soft nofile/d' \
- -e '/^elasticsearch hard nofile/d' \
- -e '/^* soft memlock/d' \
- -e '/^* hard memlock/d' \
- -e '/^elasticsearch soft memlock/d' \

三、安装部署elasticsearch
3.1 下载二进制安装包
- # esuser用户
- mkdir /home/esuser/deploy
- wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.13.2-linux-x86_64.tar.gz /home/soft
- tar -zxvf /home/soft/elasticsearch-7.13.2-linux-x86_64.tar.gz -C /home/esuser/deploy
- chown -R esuser:esuser /home/esuser/deploy
- su - esuser
- mv /home/esuser/deploy/elasticsearch-7.13.2 /home/esuser/deploy/elasticsearch-7.13.2-9300
- cp -a /home/esuser/deploy/elasticsearch-7.13.2-9300 /home/esuser/deploy/elasticsearch-7.13.2-9301
3.2 配置elasticsearch.yml
分别在每个节点配置9300和9301两个目录elasticsearch.yml文件，内容分别如下：
9300目录elasticsearch.yml
- -- esuser用户，所有节点
- -- 注意每个节点需该对应配置文件信息
- cd elasticsearch-7.13.2-9300/config
-
- cat elasticsearch.yml 内容如下(过滤#)

3.3 开启安全认证
3.3.1 生成节点证书
– 只需在一个节点生成凭证即可
3.3.1.1 创建证书办法机构CA
- # esuser用户操作，在其中一节点操作
- cd /home/esuser/deploy/elasticsearch-7.13.2-9300
- [esuser@xsky-node1 elasticsearch-7.13.2-9300]$ ./bin/elasticsearch-certutil ca
- 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]: # 按回车
- Enter password for elastic-stack-ca.p12 : # 按回车
-
- # 该命令默认在当前目录生成elastic-stack-ca.p12 单个证书文件，该文件是PKCS＃12密钥库
- # 其中包含CA的公共证书和用于对每个节点的证书签名的私钥
3.3.1.2 生成证书和私钥
- # esuser用户操作，在其中一节点操作
- [esuser@xsky-node1 elasticsearch-7.13.2-9300]$ ./bin/elasticsearch-certutil cert --ca elastic-stack-ca.p12
- 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) : # 按回车
- Please enter the desired output file [elastic-certificates.p12]: # 按回车
- Enter password for elastic-certificates.p12 : # 按回车
-
- Certificates written to /home/esuser/deploy/elasticsearch-7.13.2-9300/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.
-
- # 命令执行完后会在当前目录生成elastic-certificates.p12文件，此文件是各个节点通信凭证
3.3.1.3 移动凭证到指定目录
- # esuser用户，每个节点都需操作
- # 创建目录
- mkdir ~$ES_HOME/config/certs
-
- # 移动凭证到指定目录
- mv elastic-certificates.p12 ~$ES_HOME/config/certs
- mv elastic-stack-ca.p12 ~$ES_HOME/config/certs
-
- # 设置权限
- chmod 777 ~$ES_HOME/config/certs/elastic*.p12
3.3.2 拷贝文件
- # 当以上操作完成后，我们可以将在10.110.7.39上的deploy打包拷贝到其它物理服务器，并对每台物理服务器上的elasticsearch.yml文件进行对应修改
- # 只需调整 node.name、network.host，要分别和当前节点对应
- [root@xsky-node1 ~]# su - esuser
- [esuser@xsky-node1 ~]$ tar -cf deploy.tar ./deploy
- [esuser@xsky-node1 ~]$ scp deploy.tar 10.110.7.40:/home/esuser
- [esuser@xsky-node1 ~]$ scp deploy.tar 10.110.7.41:/home/esuser
-
- # 然后分别使用esuser用户在10.110.7.40/41解压deploy.tar，修改对应节点的elasticsearch.yml文件
3.3.3 启动验证
- -- 10.110.7.39
- [root@xsky-node1 ~]# su esuser
- [esuser@xsky-node1 root]$ cd /home/esuser/deploy
- [esuser@xsky-node1 deploy]$ ./elasticsearch-7.13.2-9300/bin/elasticsearch
- [esuser@xsky-node1 deploy]$ ./elasticsearch-7.13.2-9301/bin/elasticsearch
-
- -- 10.110.7.40
- [root@xsky-node1 ~]# su esuser
- [esuser@xsky-node2 root]$ cd /home/esuser/deploy
- [esuser@xsky-node2 deploy]$ ./elasticsearch-7.13.2-9300/bin/elasticsearch
- [esuser@xsky-node2 deploy]$ ./elasticsearch-7.13.2-9301/bin/elasticsearch
-
- -- 10.110.7.41
- [root@xsky-node1 ~]# su esuser
- [esuser@xsky-node3 root]$ cd /home/esuser/deploy
- [esuser@xsky-node3 deploy]$ ./elasticsearch-7.13.2-9300/bin/elasticsearch
- [esuser@xsky-node3 deploy]$ ./elasticsearch-7.13.2-9301/bin/elasticsearch
此时，待启动日志里不再报 master not discovered yet, this node has not previously joined a bootstrapped (v7+) cluster，其它节点已加入集群，再进行设置密码操作。
3.3.4 设置密码
使用esuser用户，只需在其中一个节点执行
- # esuser用户
- [root@xsky-node1 ~]# su - esuser
- [esuser@xsky-node1 elasticsearch-7.13.2-9300]$ ./bin/elasticsearch-setup-passwords interactive
