Centos7.0 Logstash的logstash-input-jdbc,mysql数据实时同步ElasticSearch及词库

GitHub watchers


今天我介绍的是用Logstash-input-jdbc方法同步mysql数据到es.

安装jdk1.8,采用yum安装方式,非常简单

1、查看yum库中jdk的版本

[root@localhost ~]# yum search java|grep jdk

2、选择java-1.8.0安装

[root@localhost ~]# yum install java-1.8.0-openjdk*

3、配置环境变量

[root@localhost ~]# vi /etc/profile

这里jdk1.8.0的文件夹路径是: /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.144-0.b01.el7_4.x86_64

添加如下内容,

#set java environment
JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.144-0.b01.el7_4.x86_64
JRE_HOME=$JAVA_HOME/jre
CLASS_PATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
export JAVA_HOME JRE_HOME CLASS_PATH PATH

4、环境变量生效

[root@localhost ~]# source /etc/profile

5、查看jdk是否安装成功

[root@localhost ~]# java -version

##安装 elasticsearch 2.4.6

Elasticsearch可以用包管理器通过添加弹性的包库进行安装。

1.运行以下命令来导入Elasticsearch公共GPG钥匙插入转:

sudo rpm --import http://packages.elastic.co/GPG-KEY-elasticsearch

2.创建Elasticsearch一个新的yum库文件。请注意,这是一个命令:

echo '[elasticsearch-2.x]
name=Elasticsearch repository for 2.x packages
baseurl=http://packages.elastic.co/elasticsearch/2.x/centos
gpgcheck=1
gpgkey=http://packages.elastic.co/GPG-KEY-elasticsearch
enabled=1
' | sudo tee /etc/yum.repos.d/elasticsearch.repo

3.用这个命令安装Elasticsearch:

sudo yum -y install elasticsearch

4.Elasticsearch现已安装完毕。让我们编辑配置:

sudo vi /etc/elasticsearch/elasticsearch.yml

修改 Cluster名字自取:`cluster.name: my-shanhai-cluster`

修改 Node节点名字自取: `node.name: node-shanhai`

修改 Network访问IP为本机:`network.host: 192.168.0.60`

(先按ESC,再按:wq)保存并退出elasticsearch.yml。

(设置显示行::set nu

5.现在启动Elasticsearch:

sudo systemctl start elasticsearch

(注意:elasticsearch 启动过程有点慢,大概30s左右,耐心等待!)

6.然后运行以下命令将在系统启动后自动启动Elasticsearch:

sudo systemctl enable elasticsearch

7.打开浏览器访问本机IP测试http://192.168.0.60:9200/

{
"name": "node-shanhai",
"cluster_name": "my-shanhai-cluster",
"cluster_uuid": "9kGKZvlqQimXxaRf3uoGCQ",
"version": {
"number": "2.4.6",
"build_hash": "5376dca9f70f3abef96a77f4bb22720ace8240fd",
"build_timestamp": "2017-07-18T12:17:44Z",
"build_snapshot": false,
"lucene_version": "5.5.4"
},
"tagline": "You Know, for Search"
}

##安装ElasticSearch Head 插件

1.首先查找elasticsearch 安装目录

find /* -name elasticsearch

于是我看到了/usr/share/elasticsearch/bin/这个目录,plugin就在里面了

2.进入该目录执行安装命令:

/usr/share/elasticsearch/bin/plugin install mobz/elasticsearch-head

3.安装成功后打开浏览器验证:

http://192.168.0.60:9200/_plugin/head/

##安装ElasticSearch IK分词器

1.进入elasticsearch/plugins插件目录:

cd /usr/share/elasticsearch/plugins

2.创建ik文件夹

mkdir ik

3.下载压缩包,ik 包版本要跟elasticsearch 版本对应:

wget https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v1.9.1/elasticsearch-analysis-ik-1.9.1.zip

4.直接压缩到ik 文件目录下:

uzip elasticsearch-analysis-ik-1.9.1.zip

5.进入elasticsearch.yml文件增加下面一行,然后重启下ES

index.analysis.analyzer.ik.type : 'ik'

6.打开浏览器IK测试:

http://192.168.0.60:9200/index/_analyze?analyzer=ik&text=中华人民共和国&pretty=true

##安装Logstash 2.2

1.我们创建和编辑Logstash新百胜库文件:

sudo vi /etc/yum.repos.d/logstash.repo

2.添加以下配置:

[logstash-2.2]
name=logstash repository for 2.2 packages
baseurl=http://packages.elasticsearch.org/logstash/2.2/centos
gpgcheck=1
gpgkey=http://packages.elasticsearch.org/GPG-KEY-elasticsearch
enabled=1

保存并退出。

3.用这个命令安装Logstash:

sudo yum -y install logstash

4.进入logstash bin目录:

`cd /opt/logstash/bin`

5.运行:

./logstash -e 'input{stdin{}}output{stdout{codec=>rubydebug}}'

6.启动后输入:xing test ,显示结果如下表示正常:

OpenJDK 64-Bit Server VM warning: If the number of processors is expected to increase from one, then you should configure the number of parallel GC threads appropriately using -XX:ParallelGCThreads=N
xing test
Settings: Default pipeline workers: 1
Logstash startup completed
{
   "message" => "xing test",
  "@version" => "1",
"@timestamp" => "2017-10-12T09:46:05.884Z",
  "host" => "shanghai.ai01"
}

##安装连mysql java 驱动包

1.先进入logstash 根目录:

cd /opt/logstash

2.下载mysql-connector-java-5.1.44压缩包:

wget https://cdn.mysql.com//Downloads/Connector-J/mysql-connector-java-5.1.44.tar.gz

3.解压:

tar -zxvf mysql-connector-java-5.1.44.tar.gz

4.将解压的 mysql-connector-java-5.1.44-bin.jar 放到根目录下

mv mysql-connector-java-5.1.44-bin.jar /opt/logstash/

5.在该目录下新建etc,并创建.cnf和.sql文件,名字自取:

  mkdir -p etc
  cd etc
  vi wp.cnf
  vi wp.sql

6.配置wp.cnf文件:

input {
stdin {
}
jdbc {
# 数据库地址  端口  数据库名
  jdbc_connection_string => "jdbc:mysql://192.168.0.60:3306/wordpress"
# 数据库用户名
  jdbc_user => "root"
# 数据库密码
  jdbc_password => "1"
# mysql java驱动地址
  jdbc_driver_library => "/opt/logstash/mysql-connector-java-5.1.44-bin.jar"
  jdbc_driver_class => "com.mysql.jdbc.Driver"
  jdbc_paging_enabled => "true"
  jdbc_page_size => "50000"
# sql 语句文件
  statement_filepath => "/opt/logstash/etc/wp.sql"
  schedule => "* * * * *"
  type => "jdbc"
}
}
output {
elasticsearch {
hosts => ["192.168.0.61:9200"]
index => "hangzhou"
document_id => "%{id}"
}
stdout {
codec => json_lines
}
}

保存并退出

7.启动logstash:

bin/logstash -f etc/wp.conf

8.然后你就会看到查询的数据以json的格式显示出来,在head插件里有日志记录显示,表明配置成功!
