Docker 安装单机 Canal

一、 Docker安装

略

二、修改MySQL配置

2.1 修改my.cnf配置

对于自建 MySQL , 需要先开启 Binlog 写入功能，配置 binlog-format 为 ROW 模式，my.cnf 中配置如下

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

记得重启MySQL

2.2 新建MySQL用户

授权 canal 链接 MySQL 账号具有作为 MySQL slave 的权限, 如果已有账户可直接 grant

-- 新建用户
CREATE USER canal IDENTIFIED BY 'canal';  

-- GRANT ALL PRIVILEGES ON *.* TO 'canal'@'%' ;
GRANT SELECT, REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO 'canal'@'%';

-- 刷新权限
FLUSH PRIVILEGES;

三、 Canal Admin部署

2.1 下载镜像

docker hub

#拉取 canal Admin镜像
$ docker pull canal/canal-admin:v1.1.4

2.2 启动容器

         -e canal.adminUser=admin \
         -e canal.adminPasswd=admin

#查看启动日志
$ docker logs canal-admin

#查看容器日志
$ docker logs canal-server
