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;

# 查询MySQL数据库中某一个用户授予的权限
mysql> show grants for canal;
+---------------------------------------------------------------------------+
| Grants for canal@%                                                        |
+---------------------------------------------------------------------------+
| GRANT SELECT, REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO 'canal'@'%' |
+---------------------------------------------------------------------------+

组建HA集群
地址：https://github.com/alibaba/canal/wiki/AdminGuide

# 重新获得一份解压缩的目录，比如canal_2
# 修改原有的canal数据
vim canal.properties
    canal.zkServers=localhost:2181,localhost:2182,localhost:2183,
    canal.instance.global.spring.xml = classpath:spring/default-instance.xml
# 然后把这个文件复制到canal_2对应目录下，在canal_2对应目录下再次修改
vim canal.properties
    canal.port = 11114
    canal.metrics.pull.port = 11115
vim canal_local.properties
    canal.admin.port = 11113

# 把canal example目录下的instance.properties复制到canal_2对应目录下，并在canal_2对应目录下再次修改
vim instance.properties
    canal.instance.mysql.slaveId = 124 ##另外一台机器改成1235，保证slaveId不重复即可

# 注意： 两台机器上的instance目录的名字需要保证完全一致，HA模式是依赖于instance name进行管理，同时必须都选择default-instance.xml配置

# 然后分别启动

# 总结一下：
# 1. 俩配置文件中使用的三个端口号需要不一样
# 2. 使用default-instance.xml文件
# 3. MySQL的slaveId不一样
# 4. 两台机器上的instance目录的名字需要保证完全一致

# 启动后，可以查看logs/example/example.log，只会看到一台机器上出现了启动成功的日志。
# 或者通过查看一下zookeeper中的节点信息，可以知道当前工作的节点为localhost:11111
# get /otter/canal/destinations/example/running

# canal-admin 使用WEB UI界面查看管理canal

# canal-admin的限定依赖：
#    MySQL，用于存储配置和节点等相关数据
#    canal版本，要求>=1.1.4 (需要依赖canal-server提供面向admin的动态运维管理接口)

# 在kafka eagle平台使用KSQL查询数据

# 左侧导航

# 1.先在Topic-List中查看到Topic Name和Partition Indexes的值
# ID    Topic Name  Partition Indexes   Partition Numbers   Created Modify  Operate
# 1 canal_manager   [0] 1   2019-09-20 17:27:15 2019-09-20 17:27:15 

# 2. 在Topic-KSQL中输入查询语句
# select * from "canal_manager" where "partition" in (0) limit 1
# 下方会显示查询所用时间和查询后的结果

# 在如下目录的文件中可以查看具体的异常信息，一般都会提示具体的错误

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

# 或者在kafka eagle平台使用KSQL查询数据，上述文档已经说过了

使用canal获取mysql的binlog传输给kafka，并交由logstash获取实验步骤
