安裝logstash-input-jdbc插件

安裝logstash-input-jdbc插件,實現數據的插入

1.安裝gem

yum install gem -y

2.替換ruby庫（兩種國內源+淘寶源）

2.1.1替換為國內源

gem sources --add https://gems.ruby-china.com/ --remove https://rubygems.org/
gem sources -l

2.1.2修改配置文件

cd /opt/inst/logstash722/
vi Gemfile
#修改Gemfile文件
#source https://rubygems.org/
httpsvi Gemfile.lockgems.ruby-china.com/
vi Gemfile.lock
#remote: https://rubygems.org/
https://gems.ruby-china.com/

2.2 同上替換ruby為淘寶源(如果上述替換國內源不成功，可以換此方法)

gem sources --add https://ruby.taobao.org/ --remove https://rubygems.org/
gem sources -l

由于修改ruby鏡像庫為淘寶庫并沒有成功，這里就需要修改Gemfile文件里面的數據源：

cd /opt/inst/logstash722/
vi Gemfile
#修改Gemfile文件
#source https://rubygems.org/
source "https://ruby.taobao.org"
#remote: https://rubygems.org/
remote: https://ruby.taobao.org

3.安裝logstash-input-jdbc

3.1 到logstash的bin目錄下運行下面的命令，查看可用的插件

cd bin
./logstash-plugin list --verbose

3.2 上述操作看到可以使用的logstash-input-jdbc版本是4.3.3，安裝JDBC

unzip logstash-input-jdbc-4.3.3.zip
mv logstash-input-jdbc-4.3.3 /opt/inst/log_jdbc433
cd log_jdbc433/

3.3 配置Gemfile文件

vi Gemfile
source 'https://gems.ruby-china.com/'

4.測試是否成功

4.1 提供數據

需要一個mysql驅動包，sql文件,以及conf配置文件

input {

    jdbc {
      # mysql jdbc connection string to our backup databse
      jdbc_connection_string => "jdbc:mysql://169.254.211.100:3306/test"
      # the user we wish to excute our statement as
      jdbc_user => "root"
      jdbc_password => "root"
      # the path to our downloaded jdbc driver
      jdbc_driver_library => "/opt/inst/logstash722/sql/mysql-connector-java-5.1.40-bin.jar"
      # the name of the driver class for mysql
      jdbc_driver_class => "com.mysql.jdbc.Driver"
      jdbc_paging_enabled => "true"
      jdbc_page_size => "50000"
      statement_filepath => "/opt/inst/logstash722/sql/logs_20171206.sql"
      schedule => "*/1 * * * *"
      type => "jdbc"
    }
}

filter {
    json {
        source => "message"
        remove_field => ["message"]
    }
}

output {
    elasticsearch {
        hosts => "169.254.211.100:9200"
        index => "logs_20171206"
        document_id => "%{id}"
    }
    stdout {
        codec => json_lines
    }
}

4.2 實現logstash把文件寫進mysq數據庫l中

cd /opt/inst/logstash722/bin
./logstash -f /opt/logfiter/mysql.conf
