canal同步mysql到mysql主要配置

1、canal.admin 配置和启动命令

cat conf/application.yml

bash 复制代码

server:
  port: 8089
spring:
  jackson:
    date-format: yyyy-MM-dd HH:mm:ss
    time-zone: GMT+8

spring.datasource:
  address: 127.0.0.1:3308
  database: canal_manager
  username: canal
  password: canal
  #driver-class-name: com.mysql.jdbc.Driver
  driver-class-name: com.mysql.cj.jdbc.Driver
  #  8.0 添加&allowPublicKeyRetrieval=true
  url: jdbc:mysql://${spring.datasource.address}/${spring.datasource.database}?useUnicode=true&characterEncoding=UTF-8&useSSL=false
  hikari:
    auto-commit: false
    maximum-pool-size: 30000
    minimum-idle: 10

canal:
  adminUser: admin
  adminPasswd: 123456
  admin:
    registerIp: 10.1.0.98  # 集群注册使用的IP
    serverPort: 11110  # Admin服务端口

启动命令，需要先初始化数据库。

bash 复制代码

conf/canal_manager.sql

bash 复制代码

./bin/startup.sh

2、canal.deployer 配置和启动命令

cat canal_local.properties

bash 复制代码

# register ip
canal.register.ip = 10.1.0.98

# canal admin config
canal.admin.manager = 10.1.0.98:8089
canal.admin.port = 11110
canal.admin.user = admin
#canal.admin.passwd = 123456
# select password('123456')
# 如果遇到mysql8.0，可以使用select upper(sha1(unhex(sha1('123456'))))

canal.admin.passwd = 6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9
# admin auto register
canal.admin.register.auto = true
#canal.admin.register.cluster = default
#canal.admin.register.name = default

## 注册到Admin的配置
#canal.admin.manager.url = http://10.1.0.98:8089/api/v1/${canal.admin.manager.url.base}
#canal.admin.port = 11110
#canal.admin.user = admin
#canal.admin.passwd = 123456
#
## 自动注册配置
#canal.admin.register.auto = true
#canal.admin.register.cluster = default  # 集群名称

启动命令：

bash 复制代码

./bin/startup.sh  local

3、配置 instance

启动 canal.deployer 会自动注册到admin

配置instance

bash 复制代码
