canal简介
canal是阿里巴巴开源的MySQL binlog 增量订阅&消费组件。
canal [kə’næl],译意为水道/管道/沟渠,主要用途是基于 MySQL 数据库增量日志解析,提供增量数据订阅和消费。
canal的GitHub地址: GitHub - alibaba/canal: 阿里巴巴 MySQL binlog 增量订阅&消费组件 -
canal 下载
Releases · alibaba/canal · GitHub
建议下载以下四个。其中下载源码是为了解决canal.adapter
中的一个依赖冲突,要保存在自己开发用的电脑里,后面会讲到它。
-
canal 组件用用简述:
canal的各个组件的用途各不相同,下面分别介绍下:
canal-deploy:用于监听MySQL的binlog,是一个伪装的MySQL从库,只负责从MySQL主库接收数据,不做处理。
canal-adapter:canal的客户端,从canal-deploy中获取数据,然后同步数据到目标数据源,我们用它将数据存储到ElasticSearch中。
canal-admin:为canal提供整体配置管理、节点运维等面向运维的功能,提供相对友好的WebUI操作界面,方便更多用户快速和安全的操作
二、Mysql 配置
2.1. 开启binlog
先配置mysql数据库,打开binlog写入功能,设置binlog-format为ROW。
配置文件路径为 /etc/my.cnf
vi /etc/my.cnf
直接覆盖即可
[mysqld]
basedir=/usr/local/mysql-8.0/
datadir=/usr/local/mysql-8.0/data/
socket=/tmp/mysql.sock
character-set-server=UTF8MB4
symbolic-links=0
## 设置server_id,同一局域网中需要唯一
server-id=1
## 设置使用的二进制日志格式(mixed,statement,row)
binlog_format="ROW"
## 开启二进制日志功能
log_bin=/usr/local/mysql-8.0/mysql_bin
2.2. 验证binlog状态
配置完成后重新启动MySQL,重启后执行下面的SQL语句查看binlog是否启用:
systemctl restart mysql
mysql -uroot -p123456
show variables like '%log_bin%';
详情参考:MySQL8.0.26 开启bin_log日志 linux
2.3. 创建账号
接下来需要创建一个拥有从库权限的账号,用于订阅binlog,这里创建的账号为canal:canal;
CREATE USER canal IDENTIFIED BY 'canal';
2.4. 权限赋予
GRANT SELECT, REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO 'canal'@'%';
2.5. 刷新权限
FLUSH PRIVILEGES;
2.6. 创建数据库
create database dianpingdb;
2.7. 初始化表结构
任选一种,或者都初始化
- demo 案例:
-- ----------------------------
-- Table structure for student
-- ----------------------------
DROP TABLE IF EXISTS `student`;
CREATE TABLE `student` (
`id` varchar(32) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL,
`name` varchar(100) CHARACTER SET utf8 COLLATE utf8_unicode_ci NULL DEFAULT NULL,
`grade` tinyint(1) NULL DEFAULT 1,
`class` tinyint(1) NULL DEFAULT 0,
`birthday` date NULL DEFAULT NULL,
PRIMARY KEY (`id`) USING BTREE
) ENGINE = InnoDB CHARACTER SET = utf8 COLLATE = utf8_unicode_ci ROW_FORMAT = Dynamic;
- 真实企业案例:
该表结构取自真实开源大众点评项目,直接下载初始化即可
https://gitee.com/gb_90/dianping/tree/master/doc/dianping.sql
2.8. 初始化数据
任选一种,或者都初始化
- demo 案例数据:
INSERT INTO `student` VALUES ('1', '大家好,我是gblfy', 1, 0, '2021-11-23');
INSERT INTO `student` VALUES ('2', '大家好,我是gblfy2', 1, 0, '2021-11-23');
INSERT INTO `student` VALUES ('3', '大家好,我是gblfy3', 1, 0, '2021-11-23');
INSERT INTO `student` VALUES ('4', '大家好,我是gblfy4', 1, 0, '2021-11-23');
INSERT INTO `student` VALUES ('5', '大家好,我是gblfy5', 1, 0, '2021-11-23');

三、canal-deployer的配置与使用
3.1. 解压deployer
mkdir /app/canal/canal.deployer -p
cd /app/canal/
tar -zxvf canal.deployer-1.1.5.tar.gz -C /app/canal/canal.deployer
3.2. 解压后目录结构
.
├── bin
│ ├── restart.sh
│ ├── startup.bat
│ ├── startup.sh
│ └── stop.sh
├── conf
│ ├── canal_local.properties
│ ├── canal.properties
│ ├── example
│ │ └── instance.properties
│ ├── logback.xml
│ ├── metrics
│ │ └── Canal_instances_tmpl.json
│ └── spring
├── lib
├── logs
└── plugin
3.3. 修改配置
修改配置文件conf/example/instance.properties
cd /app/canal/canal.deployer/conf/example
vim instance.properties
修改下面几项配置:我这里只修改了slaveId其他的都可以默认
关键信息:
# 需要同步数据的MySQL地址
canal.instance.master.address=127.0.0.1:3306
canal.instance.master.journal.name=
canal.instance.master.position=
canal.instance.master.timestamp=
canal.instance.master.gtid=
# 用于同步数据的数据库账号
canal.instance.dbUsername=canal
# 用于同步数据的数据库密码
canal.instance.dbPassword=canal
# 数据库连接编码
canal.instance.connectionCharset = UTF-8
# 需要订阅binlog的表过滤正则表达式
canal.instance.filter.regex=.*\\..*
3.4. 启动deployer
cd /app/canal/canal.deployer
bin/startup.sh && tail -f logs/canal/canal.log
四、canal-adaptor的使用和配置
4.1. 解压adaptor
mkdir /app/canal/canal.adapter -p
cd /app/canal/
tar -zxvf canal.adapter-1.1.5.tar.gz -C /app/canal/canal.adapter
4.2. 解压后目录结构

4.3. 修改配置
修改配置文件conf/application.yml
cd /app/canal/canal.adapter
vim conf/application.yml
4.3. 新建配置
cd /app/canal/canal.adapter/conf/es7/
- demo案例:
vim student.yml
写入以下内容
dataSourceKey: defaultDS
destination: student
groupId: g1
esMapping:
_index: student
_type: _doc
_id: _id
sql: "SELECT
id as _id,
name,
grade,
class,
birthday
from student"
etlCondition: "where birthday>={}"
commitBatch: 3000
- 企业案例:
vim shop.yml
写入以下内容
dataSourceKey: defaultDS
destination: example
groupId: g1
esMapping:
_index: shop
_type: _doc
_id: id
upsert: true
sql: "SELECT a.id,a.name,a.tags,CONCAT(a.latitude,',',a.longitude) AS location,a.remark_score,a.price_per_man,a.category_id,b
.`name` as category_name,a.seller_id,c.remark_score as seller_remark_score,c.disabled_flag as seller_disabled_flag FROM shop a
INNER JOIN category b on a.category_id =b.id INNER JOIN seller c on c.id = a.seller_id"
commitBatch: 3000
4.4. 启动adapter
cd /app/canal/canal.adapter
bin/startup.sh
4.5. 查看adapter日志
tail -100f /app/canal/canal.adapter/logs/adapter/adapter.log
4.6. 异常方案
看到有以下报错:

在百度上查了一下,找到了这篇文章canal本地运行异常:class com.alibaba.druid.pool.DruidDataSource cannot be cast to
确认是jar包冲突导致的bug,于是下载了源码压缩包canal-canal-1.1.5.zip
下载地址 https://github.com/alibaba/canal/archive/refs/tags/canal-1.1.5.zip
解压缩后用自己的开发工具打开项目,修改maven依赖
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid</artifactId>
<scope>provided</scope>
</dependency>
项目根目录下执行mvn clean package,打包,然后到canal-canal-1.1.5\client-adapter\es7x\target\
目录下找到client-adapter.es7x-1.1.5-jar-with-dependencies.jar
将这个文件复制到/app/canal/canal_adapter/plugin/
下,重启adapter
,查看日志
/app/canal/canal_adapter/bin/restart.sh
tail -100f /app/canal/canal_adapter/logs/adapter/adapter.log
成功启动,不再出现报错。
五、中间件启动
5.1. 启动es
/app/elasticsearch-7.15.2
bin/elasticsearch -d && tail -f logs/dianping-app.log
5.2. 启动kibana
如果没下载,可以参考:kibana-7.15.2 一分钟下载、安装、部署 linux,如不想安装直接跳过,也可以验证的,不影响效果
cd /app/kibana-7.15.2-linux-x86_64/
bin/kibana
5.3. 启动canal.adapter
cd /app/canal/canal.adapter
bin/startup.sh
六、全量同步(demo)
在Elasticsearch中创建索引,和MySQL中的student表相对应,可以直接使用postman或者curl命令,也可以安装kibana或者其它Elasticsearch管理插件
6.1. 创建索引
- 第一种:curl命令
curl --location --request PUT 'http://192.168.159.134:9200/student' \
--header 'Content-Type: application/json' \
--data '{"mappings":{"properties": {"name": {"type": "text"},"grade":{"type": "short"},"class":{"type": "short"},"birthday": {"type": "date","format": "yyyy-MM-dd HH:mm:ss||date_time_no_millis||strict_date_optional_time||epoch_millis"}}}}'
执行结果显示创建成功。
[root@localhost canal_adapter]# curl --location --request PUT 'http://192.168.159.134:9200/student' \
> --header 'Content-Type: application/json' \
> --data '{"mappings":{"properties": {"name": {"type": "text"},"grade":{"type": "short"},"class":{"type": "short"},"birthday": {"type": "date","format": "yyyy-MM-dd HH:mm:ss||date_time_no_millis||strict_date_optional_time||epoch_millis"}}}}'{"acknowledged":true,"shards_acknowledged":true,"index":"student"}
[root@localhost canal_adapter]#
6.2. 执行全量同步
curl -X POST http://192.168.159.134:8081/etl/es7/student.yml
返回结果:{"succeeded":true,"resultMessage":"导入ES 数据:5 条"}
七、全量同步(企业)
7.1. curl命令创建索引
curl --location --request PUT 'http://localhost:9200/shop' \
--header 'Content-Type: application/json' \
--data '{
"settings": {
"number_of_shards": 1,
"number_of_replicas": 1
}
, "mappings": {
"properties": {
"id":{"type": "integer"},
"name":{"type": "text","analyzer": "ik_max_word","search_analyzer": "ik_smart"},
"tags":{"type": "text","analyzer": "whitespace","fielddata": true},
"location":{"type": "geo_point"},
"remark_score":{"type": "double"},
"price_per_man":{"type": "integer"},
"category_id":{"type": "integer"},
"category_name":{"type": "keyword"},
"seller_id":{"type": "integer"},
"seller_remark_score":{"type": "double"},
"seller_disabled_flag":{"type": "integer"}
}
}
}';
执行结果显示创建成功。
{"acknowledged":true,"shards_acknowledged":true,"index":"shop"}
下面给大家介绍kibana方式,kibana只是提供了一个图形化的页面控制台。
7.2. kibana创建索引
使用 kibana-7.15.2
控制台
# 定义门店索引结构
PUT /shop
{
"settings": {
"number_of_shards": 1,
"number_of_replicas": 1
}
, "mappings": {
"properties": {
"id":{"type": "integer"},
"name":{"type": "text","analyzer": "ik_max_word","search_analyzer": "ik_smart"},
"tags":{"type": "text","analyzer": "whitespace","fielddata": true},
"location":{"type": "geo_point"},
"remark_score":{"type": "double"},
"price_per_man":{"type": "integer"},
"category_id":{"type": "integer"},
"category_name":{"type": "keyword"},
"seller_id":{"type": "integer"},
"seller_remark_score":{"type": "double"},
"seller_disabled_flag":{"type": "integer"}
}
}
}
7.3. 执行全量同步url
curl -X POST http://192.168.159.134:8081/etl/es7/shop.yml
返回结果:{"succeeded":true,"resultMessage":"导入ES 数据:16 条"}
7.4 使用kibana控制台查看全量同步的数据,不是必须的,只是看一下全量同步数据,可以跳过。
7.4. kibana查询数据
使用kibana控制台查看全量同步的数据
# 查询student索引
GET /student/_search
# 查询shop索引
GET /shop/_search
# 删除student索引
DELETE /student
# 删除shop索引
DELETE /shop
7.5. canal 增量同步
