mysql+canal+kafka+elasticsearch构建数据查询平台

1. 实验环境

CPU:4

内存：8G

ip:192.168.0.187

开启iptables防火墙

关闭selinux

java >=1.5

使用yum方式安装的java,提前配置好JAVA_HOME环境变量

vim /etc/profile.d/java.sh
	#!/bin/bash

	export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk # 路径根据实际情况而定
	export PATH=$PATH:$JAVA_HOME/bin
source /etc/profile.d/java.sh

2. MySQL信息

mysql账号

root

MySQL密码

liykpntuu9?C

操作

vim /etc/my.cnf
[mysqld]
log-bin=mysql-bin # 开启 binlog
binlog-format=ROW # 选择 ROW 模式
server_id=1 # 配置 MySQL replaction 需要定义，不要和 canal 的 slaveId 重复

service mysqld restart

登陆数据库后操作

CREATE USER canal IDENTIFIED BY 'canal!%123AD';
GRANT SELECT, REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO 'canal'@'%';
FLUSH PRIVILEGES;

3. canal操作

# 下载
wget https://github.com/alibaba/canal/releases/download/canal-1.1.4/canal.deployer-1.1.4.tar.gz
mkdir -p /usr/local/canal
tar -zxv -f canal.deployer-1.1.4.tar.gz -C /usr/local/canal

# 修改连接数据库的配置文件
cd /usr/local/canal
vim conf/example/instance.properties
	## mysql serverId
	canal.instance.mysql.slaveId = 123
	#position info，需要改成自己的数据库信息
	canal.instance.master.address = 127.0.0.1:3306
	canal.instance.master.journal.name =
	canal.instance.master.position =
	canal.instance.master.timestamp =
	#canal.instance.standby.address =
	#canal.instance.standby.journal.name =
	#canal.instance.standby.position =
	#canal.instance.standby.timestamp =
	#username/password，需要改成自己的数据库信息
	canal.instance.dbUsername = canal
	canal.instance.dbPassword = canal!%123AD
	canal.instance.defaultDatabaseName =
	canal.instance.connectionCharset = UTF-8
	#table regex
	canal.instance.filter.regex = .\*\\\\..\*

6. 投递数据到Kafka

# 先进行canal配置，改动配置文件canal.properties
# serverMode改为kafka
vim conf/canal.properties
	canal.serverMode = kafka
	canal.mq.servers = localhost:9092,localhost:9093,localhost:9094

vim conf/example/instance.propties
	# mq config
	canal.mq.topic=canal_manager # 填写数据库库名，表示这个数据库的所有表的操作都在这个topic下
	# dynamic topic route by schema or table regex
	# canal.mq.dynamicTopic=.*\\..*
	canal.mq.partition=0
	# hash partition config
	# canal.mq.partitionsNum=10
	# canal.mq.partitionHash=.*\\..*

# 以上具体规则详看官方文档

# kafka开启消息队列的自动创建topic模式，相关配置在kafka的server.properties
echo 'auto.create.topics.enable=true' >> config/server-1.properties
echo 'auto.create.topics.enable=true' >> config/server-2.properties
echo 'auto.create.topics.enable=true' >> config/server-3.properties 

# 相关改动完成后重启canal和kafka

# 使用canal_admin平台查看canal的状态
# Server管理，操作，日志

# 使用zu ui平台查看kafka的topic情况
# 左侧导航Topic-List查看生成的topic，这里显示的是canal_manager，上面设置的那个数据库库名
# 点开Topic Name可以查看具体的数据个数

# 使用命令行kafka-console-consumer.sh --topic canal_manager --bootstrap-server localhost:9092 --from-beginning查看canal传递给kafka的数据
# 插入一条数据

# 删除一条数据

后续增加使用logstash从Kafka中拉取数据传输到elastic中且指定索引
