Linux7 中安装使用 LogStansh7.7.0

热度:12   发布时间:2024-02-22 04:38:51.0

一、下载解压

wget https://artifacts.elastic.co/downloads/logstash/logstash-7.7.0.tar.gz
tar -zxvf logstash-7.7.0.tar.gz

二、修改配置文件

(1)修改内存使用大小

cd config
vim jvm.options

修改

-Xms256m
-Xmx256m

三、自定义配置文件

cd /usr/local/elasticsearch/logstash-7.7.0/bin
mkdir mysql
cd mysql

在mysql目录下分别创建三个文件:

(1)数据传输调度配置

input {stdin { }jdbc {type => "lgb_test"codec => plain { charset => "UTF-8"}lowercase_column_names => falsejdbc_connection_string => "jdbc:mysql://192.168.1.105:3306/es"jdbc_user => "root"jdbc_password => "root"jdbc_driver_library => "/usr/local/elasticsearch/logstash-7.7.0/lib/mysql-connector-java-8.0.13.jar"jdbc_driver_class => "com.mysql.cj.jdbc.Driver"jdbc_paging_enabled => "true"#添加增量类配置record_last_run => "true"use_column_value => "true"tracking_column => "event_id"tracking_column_type => numericclean_run => "false"last_run_metadata_path => "/usr/local/elasticsearch/logstash-7.7.0/bin/mysql/sql_last_value.txt"jdbc_page_size => "50000"#获取到记录的SQL查询语句statement_filepath => "/usr/local/elasticsearch/logstash-7.7.0/bin/mysql/jdbc.sql"#定时字段 各字段含义(由左至右)分、时、天、月、年,全部为*默认含义为每>分钟都更新schedule => "10 * * * *"}}output {stdout {codec => json_lines}if[type]=="lgb_test"{elasticsearch {#ESIP地址与端口hosts => "kafka1:9200"#ES索引名称(自己定义的)index => "lgb_index_test"#文档类型document_type => "lgb_type_test"#文档类型iddocument_id => "%{event_id}"}}}

(2)查询sql语句

select event_id,timestmp,formatted_message,level_string,caller_class from logging_event where event_id > :sql_last_value ORDER BY timestmp
# :sql_last_value 是内置变量,不要改,此处可以实现增量同步mysql数据到es

(3)创建sql_last_value.txt,用于保存追踪列的最后一条记录

vim sql_last_value.txt
touch sql_last_value.txt

(4)在lib目录,增加mysql驱动包

mysql-connector-java-8.0.13

(5)启动

su es
cd /usr/local/elasticsearch/logstash-7.7.0/bin
./logstash -f mysql/dataTran.conf
