2. 下载解压

[root@canal1 ~]#
[root@canal1 ~]# wget https://github.com/alibaba/canal/releases/download/canal-1.1.5/canal.admin-1.1.5.tar.gz
[root@canal1 ~]#
[root@canal1 ~]# mkdir canal.admin-1.1.5
[root@canal1 ~]# 
[root@canal1 ~]# tar -zxvf canal.admin-1.1.5.tar.gz -C canal.admin-1.1.5
[root@canal1 ~]#

3. 初始化元数据库canal_manager

[root@canal1 ~]# 
[root@canal1 ~]# mysql -h canal3 -P 3306 -u root -pRoot_123 -e "source /root/canal.admin-1.1.5/conf/canal_manager.sql"
mysql: [Warning] Using a password on the command line interface can be insecure.
[root@canal1 ~]#

4. canal.admin-1.1.5/conf/application.yml

[root@canal1 ~]#
[root@canal1 ~]# cat canal.admin-1.1.5/conf/application.yml
server:
  port: 8089
spring:
  jackson:
    date-format: yyyy-MM-dd HH:mm:ss
    time-zone: GMT+8

spring.datasource:
  address: canal3:3306
  database: canal_manager
  username: root
  password: Root_123
  driver-class-name: com.mysql.jdbc.Driver
  url: jdbc:mysql://${spring.datasource.address}/${spring.datasource.database}?useUnicode=true&characterEncoding=UTF-8&useSSL=false
  hikari:
    maximum-pool-size: 30
    minimum-idle: 1

canal:
  adminUser: admin
  adminPasswd: admin123
[root@canal1 ~]#

5. canal.deployer-1.1.5/conf/canal.properties

在3台服务器进行操作，修改部分为：

canal.admin.manager = canal1:8089
canal.admin.user = admin
canal.admin.passwd = admin123

canal.admin.register.auto = true
canal.admin.register.cluster =

然后重启canal.deployer

6. 启动

[root@canal1 ~]#
[root@canal1 ~]# canal.admin-1.1.5/bin/restart.sh
[root@canal1 ~]#

查看logs如下：

[root@canal1 ~]# 
......省略部分......
