Elasticsearch在PHP下的使用

php操作ElasticSearch

es-php客户端安装
php环境版本要求：
PHP >=7.1.0
ext-curl
ext-json

es-php扩展下载地址：

https://www.elastic.co/guide/en/elasticsearch/client/php-api/7.x/installation.html

引在thinkphp6框架中引入elasticsearch/elasticsearch包

composer  require   elasticsearch/elasticsearch="^7.0"

连接es-php客户端
参考文档：
https://www.elastic.co/guide/en/elasticsearch/client/php-api/7.x/connceting.html

# 引入开发包use Elasticsearch\ClientBuilder;$client = ClientBuilder::create()->setHosts(['192.168.1.128:9200'])->build();

es-php索引创建删除
参考文档：
https://www.elastic.co/guide/en/elasticsearch/client/php-api/7.x/index_management.html

创建索引

$index = [            "index"=>"lampol",            "body"=>[                "mappings"=>[                    "properties"=>[                        "name"=>["type"=>"keyword"                        ],                        "age"=>["type"=>"byte"                        ],                        "addr"=>["type"=>"text","analyzer"=>"ik_max_word"                        ]                    ]                ]            ]        ];        $response = $client->indices()->create($index);

判断索引是否存在、获取mapping数据结构、删除索引index

# 判断索引是否存在$response = $client->indices()->exists(['index'=>'lampol']);# 获取mapping数据结构$response = $client->indices()->getMapping(['index'=>'lampol']);# 删除索引index$response = $client->indices()->delete(['index'=>'test1']);

es-php文档单个插入以及批量插入
文档单个插入

$doc = [            "index"=>'lampol',            "id"=>1,            "body"=>[                "name"=>"liudehua",                "age"=>33,                "addr"=>"中国广东省深圳市"            ]        ];        $response = $client->index($doc);

批量插入

$docs['body'] = [            ['index'=>['_index'=>'lampol','_id'=>2]],            ['name'=>'liming','age'=>43,'addr'=>'山东省青岛市'],            ['index'=>['_index'=>'lampol','_id'=>3]],            ['name'=>'郭富城','age'=>53,'addr'=>'山东省枣庄市']        ];        $response = $client->bulk($docs);

es-php文档查询修改删除

# 文档查询id=3$id = ['index'=>'lampol','id'=>3,'_source'=>['name','age'=>33]];$response = $client->get($id);# 查询$param = [    'index'=>'lampol',    'body'=>[        'query'=>[            'match'=>[                'addr'=>'深圳'            ]        ]    ]];$response = $client->search($param);# 文档更新id=1$doc = [          'index'=>'lampol',          'id'=>1,          'body'=>[              'doc'=>[                  'age'=>53              ]          ]      ];$response = $client->update($doc);# 文档删除id=3$id = ['index'=>'lampol','id'=>3];$response = $client->delete($id);

ES实战logstash同步mysql数据到es

logstash安装及同步插件jdbc安装配置
1）安装logstash

下载路径（7.12.0版本）
https://www.elastic.co/cn/downloads/past-releases/logstash-7-12-0

# 将logstash解压到指定目录下tar xzf logstash-7.12.0-linux-x86_64.tar.gz   -C  /usr/local/# 进入到cd /usr/local/logstash-7.12.0# 创建java包目录mkdir logstash-input-jdbc# 下载mysql-connector-java连接数据库java包放入到logstash-input-jdbc目录中https://repo1.maven.org/maven2/mysql/mysql-connector-java/# 移动到指定目录mv mysql-connector-java-8.0.12.jar /usr/local/logstash-7.12.0/logstash-input-jdbc/  

2）配置数据库连接，同是指定读取的数据库表数据

vi /usr/local/logstash-7.12.0/logstash-input-jdbc/mysql.conf# 写入内容# 数据输入input{    jdbc {        # mysql的配置信息        jdbc_connection_string => "jdbc:mysql://192.168.1.106:3306/shop?characterEncoding=utf8&useSSL=false&serverTimezone=PRC&rewriteBatchedStatements=true"        jdbc_user => "root"        jdbc_password => "root"        # java驱动程序，logstash不自带的，如果我们不指定它，logstash则在其java类路径中查找(logstash/logstash-core/lib/jars)        jdbc_driver_library => "/usr/local/logstash-7.12.0/logstash-input-jdbc/mysql-connector-java-8.0.12.jar"        jdbc_driver_class => "com.mysql.cj.jdbc.Driver"        # 定时调度器        schedule => "* * * * *"        # 指定追踪的递增字段名称        tracking_column => "id"        # 启用追踪，如果为true，则需要指定tracking_column。tracking_column值作为:sql_last_value，当设置为false时:sql_last_value为最后一次执行查询的时间        use_column_value => "true"        # 同步点文件，这个文件记录了上次的同步点，重启时会读取这个文件，这个文件可以手动修改        last_run_metadata_path => "usr/local/logstash-7.12.0/logstash-input-jdbc/tt.txt"        # 执行读取mysql数据库操作的sql语句，将数据查询出来，如果数据比较多加入limit限制        statement => "SELECT id,goods_title from goods"        # 默认时区        jdbc_default_timezone =>"Asia/Shanghai"        # 是否分页分批次从mysql中读取数据再写入es        # jdbc_paging_enabled => "true"        # jdbc_page_size => "1000"        # 追踪字段的类型。目前只有"numeric"和"timestamp"，默认numeric        # tracking_column_type => "timestamp"    }}# 过滤字段，一般不用过滤字段的filter {    mutate {        remove_field => ["@timestamp","@version"]    }}# 数据输出output{    elasticsearch {        hosts => ["http://192.168.1.128:9200"]        index => "goods"        document_id => "%{id}"    }}

3）创建指定索引goods

PUT /goods{  "mappings": {    "properties": {      "id":{        "type":"integer"      },      "goods_type":{        "type":"text",        "analyzer": "ik_max_word",        "search_analyzer": "ik_smart"      }    }  }}

4）运行logstash服务

/usr/local/logstash-7.12.0/bin/logstash -f  /usr/local/logstash-7.12.0/logstash-input-jdbc/mysql.conf
