使用背景，由于生产环境带宽不大，拉取巨量的计划素材服务部署到公司内网，把素材上传到oss，把url 同步到 生产环境。

canal 版本，下载地址：https://github.com/alibaba/canal/releases

# 下载内容
# admin: canal.admin-1.1.7-SNAPSHOT.tar.gz
# deployer: canal.deployer-1.1.7-SNAPSHOT.tar.gz
# adapter: canal.adapter-1.1.7-SNAPSHOT.tar.gz

部署 admin，如果不要管理界面，这步可以忽略

# 创建文件夹， 上传canal.admin-1.1.7-SNAPSHOT.tar.gz 文件到 /usr/local/canal
mkdir -p /usr/local/canal/admin && cd /usr/local/canal

#解压
tar -xf canal.admin-1.1.7-SNAPSHOT.tar.gz -C admin/

# cd /usr/local/canal/admin/conf 把canal_manager.sql 导入数据库
# 编辑 application.yml 配置数据库
spring.datasource:
  address: 192.168.0.31:3306
  database: canal_manager
  username: root
  password: root

# 启动服务
/usr/local/canal/admin/bin/startup.sh

浏览器访问, ip:8089 用户 admin 密码：123456

部署 canal.deployer

# 创建 deployer 文件夹， 上传canal.deployer-1.1.7-SNAPSHOT.tar.gz 文件到 /usr/local/canal  
mkdir -p /usr/local/canal/deployer && cd /usr/local/canal

# 解压
tar -xf canal.deployer-1.1.7-SNAPSHOT.tar.gz -C deployer

# 配置 admin,
cd /usr/local/canal/deployer/conf

#备份 canal.properties 
mv canal.properties canal.properties.bak

#改 canal_local.properties 为 canal.properties
mv canal_local.properties canal.properties

# 启动
/usr/local/canal/deployer/bin/startup.sh

查看效果

要是没有，手动添加下

重要的两步，配置mysql 开启 binlog，log-bin， binlog-do-db，binlog_forma

1

log-bin=/usr/local/mysql/data/mysql-bin 
expire_logs_days=5
server-id=3
gtid-mode=on
enforce-gtid-consistency=on
explicit_defaults_for_timestamp
wait_timeout=7200
interactive_timeout=7200
sync_binlog=0
expire_logs_days=7
# 指定要备份的数据库
binlog-do-db=report
binlog_format=ROW
default-time_zone = '+8:00'

2, 登录mysql 创建用户

CREATE USER 'canal'@'%' IDENTIFIED BY 'canal';
GRANT ALL ON report.* TO 'canal'@'%';
grant replication slave on *.* to 'canal'@'%' identified by 'canal';
flush privileges;

创建Instances

更重要的最后一步,部署 canal.adapter-1.1.7-SNAPSHOT.tar.gz

# 创建 adapter 文件夹， 上传canal.adapter-1.1.7-SNAPSHOT.tar.gz 文件到 /usr/local/canal  
mkdir -p /usr/local/canal/adapter && cd /usr/local/canal

# 解压
tar -xf canal.adapter-1.1.7-SNAPSHOT.tar.gz -C adapter

# 配置 Instance
cd /usr/local/canal/adapter/conf

# 配置 bootstrap.yml， canal_manager 数据库
canal:
  manager:
    jdbc:
      url: jdbc:mysql://192.168.0.31:3306/canal_manager?useUnicode=true&characterEncoding=UTF-8

### application.yml 配置目标数据库, 重要参数 report， 要跟上一步创建Instances 名称相同
canalAdapters:
  - instance: report
    groups:
    - groupId: g0
      outerAdapters:
      - name: rdb
        key: mysql_report
        properties:
          jdbc.driverClassName: com.mysql.jdbc.Driver
          jdbc.url: jdbc:mysql://192.168.0.1:3306/report?useUnicode=true
          jdbc.username: report
          jdbc.password: root

# 配置rdb
vim rdb/report.yml

# 内容 ，dataSourceKey，跟上一步创建Instances 名称相同，因为你里面配置了数据源
dataSourceKey: report
destination: report
groupId: g0
outerAdapterKey: mysql_report
concurrent: true
dbMapping:
  database: report
  table: tbl_file_report
  targetTable: tbl_file_report
  targetPk:
    id: id
  mapAll: true
  etlCondition: "where c_time>={}"
  commitBatch: 3000

查看日志

tailf /usr/local/canal/adapter/logs/adapter/adapter.log

end
