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

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
