一、准备两台centos7 虚拟机

二、新建 /home/docker-contains/es   再创建node文件夹

分别在node下新建 /data  /logs   /conf文件

在conf目录下 新建elasticsearch.yml文件如下

cluster.name: elasticsearch-cluster
node.name: es01
network.bind_host: 0.0.0.0
network.publish_host: 192.168.65.135
http.port: 9200
transport.tcp.port: 9300
http.cors.enabled: true
http.cors.allow-origin: "*"
node.master: true
node.data: true
discovery.zen.ping.unicast.hosts: ["192.168.65.135:9300","192.168.65.136:9300"]
discovery.zen.minimum_master_nodes: 1
path.logs: /usr/share/elasticsearch/logs
xpack.security.audit.enabled: true
~

回到es目录：

新建docker-compose.yml如下

version: '3'
services:
     es01:
       image:  elasticsearch:6.6.1
       container_name: es01
       restart: always
       volumes:
         - /home/docker_container/es/master/data:/usr/share/elasticsearch/data:rw
         - /home/docker_container/es/master/conf/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml
         - /home/docker_container/es/master/logs:/user/share/elasticsearch/logs:rw
         - /home/docker_container/es/master/plugin1:/usr/share/elasticsearch/plugins:rw
       ports:
         - "9200:9200"
         - "9300:9300"

另外一台机器重复上述过程：

新建elasticsearch.yml：

cluster.name: elasticsearch-cluster
node.name: es02
network.bind_host: 0.0.0.0
network.publish_host: 192.168.65.136
http.port: 9200
transport.tcp.port: 9300
http.cors.enabled: true
http.cors.allow-origin: "*"
node.master: true
node.data: true
discovery.zen.ping.unicast.hosts: ["192.168.65.135:9300","192.168.65.136:9300"]
discovery.zen.minimum_master_nodes: 1
path.logs: /usr/share/elasticsearch/logs
xpack.security.audit.enabled: true

新建docker-compose.yml:

version: '3'
services:
     es02:
       image:  elasticsearch:6.6.1
       container_name: es02
       restart: always
       volumes:
         - /home/docker-container/es/node1/data:/usr/share/elasticsearch/data:rw
         - /home/docker-container/es/node1/conf/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml
         - /home/docker-container/es/node1/logs:/user/share/elasticsearch/logs:rw
         - /home/docker-container/es/node1/plugin1:/usr/share/elasticsearch/plugins:rw
       ports:
         - "9200:9200"
         - "9300:9300"

分别在docker-compose.yml同级目录执行 

docker-compose up -d

安装kibana:

docker-compose.yml

version: '3'
services:
  kibana:
    image: kibana:6.6.1
    container_name: kibana
    volumes:
        - /home/docker_container/kibana/conf/kibana.yml:/usr/share/kibana/config/kibana.yml
    restart: always
    ports:
        - 5601:5601

kibana.yml:

elasticsearch.hosts: ["http://192.168.65.135:9200"]
server.host: "0.0.0.0"
xpack.monitoring.ui.container.elasticsearch.enabled: true
i18n.locale: zh-CN
~

如果出现  Kibana server is not ready yet

第一点：KB、ES版本不一致（网上大部分都是这么说的）

解决方法：把KB和ES版本调整为统一版本

第二点：kibana.yml中配置有问题（通过查看日志，发现了Error: No Living connections的问题）

解决方法：将配置文件kibana.yml中的elasticsearch.url改为正确的链接，默认为: http://elasticsearch:9200

改为http://自己的IP地址:9200

第三点：浏览器没有缓过来

解决方法：刷新几次浏览器（狂刷 我刷了 6遍才出来）。
 

logstash:

logstash采用非docker安装，上传logstash-6.4.3.tar.gz至/home/software目录

解压缩gz包，进入到解压后的logstash-6.4.3目录

编辑：vim config/pipelines.yml  （如果需要连接多个 只需在后面追加pipeline.id和path.config，切记pipeline.id不能重复）

#   Default is path.data/dead_letter_queue
#
#   path.dead_letter_queue:
- pipeline.id: table1
  path.config: "/home/software/logstash-6.4.3/conf/MySQL_1.conf"
- pipeline.id: table2
  path.config: "/home/software/logstash-6.4.3/conf/mysql.conf"

mysql.conf:

input {
  jdbc {
    jdbc_driver_library => "/home/software/logstash-6.4.3/sql/mysql-connector-java-5.1.46.jar"
    jdbc_driver_class => "com.mysql.jdbc.Driver"
    jdbc_connection_string => "jdbc:mysql://ip:3306/test"
    jdbc_user => "root"
    jdbc_password => ""
    schedule => "* * * * *"
    statement => "SELECT * FROM user WHERE update_time >= :sql_last_value"
    use_column_value => true
    tracking_column_type => "timestamp"
    tracking_column => "update_time"
    last_run_metadata_path => "syncpoint_table"
  }
}


output {
    elasticsearch {
        # ES的IP地址及端口
        hosts => ["192.168.65.135:9200","192.168.65.136:9200"]
        # 索引名称 可自定义
        index => "user"
        # 需要关联的数据库中有有一个id字段，对应类型中的id
        document_id => "%{id}"
        document_type => "user"
    }
    stdout {
        # JSON格式输出
        codec => json_lines
    }
}

mysql_1.conf:

input {
  jdbc {
    jdbc_driver_library => "/home/software/logstash-6.4.3/sql/mysql-connector-java-5.1.46.jar"
    jdbc_driver_class => "com.mysql.jdbc.Driver"
    jdbc_connection_string => "jdbc:mysql://ip:3306/lvz_goods?autoReconnect=true&useUnicode=true&createDatabaseIfNotExist=true&characterEncoding=utf8&useSSL=false&serverTimezone=GMT%2B8"
    jdbc_user => "root"
    jdbc_password => ""
    schedule => "* * * * *"
    statement => "SELECT * FROM lvz_product WHERE update_time >= :sql_last_value"
    use_column_value => true
    tracking_column_type => "timestamp"
    tracking_column => "update_time"
    last_run_metadata_path => "syncpoint_table"
  }
}


output {
    elasticsearch {
        # ES的IP地址及端口
        hosts => ["192.168.65.135:9200","192.168.65.136:9200"]
        # 索引名称 可自定义
        index => "goods"
        # 需要关联的数据库中有有一个id字段，对应类型中的id
        document_id => "%{id}"
        document_type => "goods"
    }
    stdout {
        # JSON格式输出
        codec => json_lines
    }
}

注意：需要把mysql连接包放到对应目录；至此三大件安装就完成了

es整合ik和拼音分词器    1下载elasticsearch-analysis-ik-6.6.1.zip

分别上传到两台机器上的node1和 node2目录 ，解压重命名为ik 

2下载elasticsearch-analysis-pinyin-6.6.1.zip
分别上传到两台机器上的node1和 node2目录 ，解压重命名为pinyin

编辑docker-compose文件 挂载：

 /home/docker-container/es/node1/plugin1:/usr/share/elasticsearch/plugins:rw

重启es，到kibana界面 ：

执行

先删除goods索引

在goods索引自定义ik和拼音分词器，ik_smart_pinyin：

DELETE  /goods
PUT /goods
{
   "settings": {
        "analysis": {
            "analyzer": {
                "ik_smart_pinyin": {
                    "type": "custom",
                    "tokenizer": "ik_smart",
                    "filter": ["my_pinyin", "word_delimiter"]
                },
                "ik_max_word_pinyin": {
                    "type": "custom",
                    "tokenizer": "ik_max_word",
                    "filter": ["my_pinyin", "word_delimiter"]
                }
            },
            "filter": {
                "my_pinyin": {
                    "type" : "pinyin",
                    "keep_separate_first_letter" : true,
                    "keep_full_pinyin" : true,
                    "keep_original" : true,
                    "limit_first_letter_length" : 16,
                    "lowercase" : true,
                    "remove_duplicated_term" : true 
                }
            }
        }
  }
  
}

指定goods索引为ik_smart_pinyin

POST /goods/_mapping/goods

    image: wurstmeister/zookeeper
    ports:
      - "2181:2181"

  kafka:
    image: wurstmeister/kafka
