mysql+canal+kafka+elasticsearch構建數據查詢平臺

1. 實驗環境

CPU:4
內存：8G
ip:192.168.0.187

開啓iptables防火牆
關閉selinux
java >=1.5
使用yum方式安裝的java,提前配置好JAVA_HOME環境變量

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

    export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk # 路徑根據實際情況而定
    export PATH=$PATH:$JAVA_HOME/bin
source /etc/profile.d/java.sh

2. MySQL信息

mysql賬號
root
MySQL密碼
liykpntuu9?C

操作

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

service mysqld restart

登陸數據庫後操作

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

3. canal操作

# 下載
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

# 修改連接數據庫的配置文件
cd /usr/local/canal
vim conf/example/instance.properties
    ## mysql serverId
    canal.instance.mysql.slaveId = 123
    #position info，需要改成自己的數據庫信息
    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，需要改成自己的數據庫信息
    canal.instance.dbUsername = canal  
    canal.instance.dbPassword = canal!%123AD
    canal.instance.defaultDatabaseName =
    canal.instance.connectionCharset = UTF-8
    #table regex
    canal.instance.filter.regex = .\*\\\\..\*

# 啓動
bash bin/startup.sh

6. 投遞數據到Kafka

# 先進行canal配置，改動配置文件canal.properties
# serverMode改爲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 # 填寫數據庫庫名，表示這個數據庫的所有表的操作都在這個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=.*\\..*

# 以上具體規則詳看官方文檔

# kafka開啓消息隊列的自動創建topic模式，相關配置在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 

# 相關改動完成後重啓canal和kafka

# 使用canal_admin平臺查看canal的狀態
# Server管理，操作，日誌

# 使用zu ui平臺查看kafka的topic情況
# 左側導航Topic-List查看生成的topic，這裏顯示的是canal_manager，上面設置的那個數據庫庫名
# 點開Topic Name可以查看具體的數據個數

# 使用命令行kafka-console-consumer.sh --topic canal_manager --bootstrap-server localhost:9092 --from-beginning查看canal傳遞給kafka的數據
# 插入一條數據
