Canal安装
一、安装canal_admin
从官方下载canal.admin-1.1.4.tar.gz文件。
1、脚本执行
连接mysql数据库，执行canal_manager.sql脚本。
执行成功后，效果如下：
2、canal.admin安装
1)解压文件canal.admin-1.1.4.tar.gz
2)修改配置文件application.yml
注：红色部分修改为实际的配置。
3)配置集群及主配置
通过界面配置集群信息：zookeeper的地址和主配置信息。
canal.properties，载入主配置，然后按需修改：

二、安装canal_deployer
从官方下载canal.deployer-1.1.4.tar.gz文件。
1）解压文件canal.admin-1.1.4.tar.gz
2）修改canal_local.properties
我们有网段要求，需要直接绑定到指定IP。
# register ip
canal.register.ip = 172.30.xxx.xxx
# canal admin config
canal.admin.manager = 172.30.xxx.xxx:8089
canal.admin.port = 11110
canal.admin.user = admin
canal.admin.passwd = 29C41D42A39BA0FD07C298463639112C9A190F9A
# admin auto register
canal.admin.register.auto = true
canal.admin.register.cluster = Canal_Master
3)启动
./startup.sh local
4）通过界面进行实例新建即可。
instance.properties配置参考：
## mysql serverId , v1.0.26+ will autoGen
# canal.instance.mysql.slaveId=0
# enable gtid use true/false
canal.instance.gtidon=false
# position info

#canal.mq.partitionsNum=3
#canal.mq.partitionHash=test.table:id^name,.*\\..*
需要注意的点：
1、canal_deployer部署的时候，两台机器与canal-admin建议都在一个用户下，建议别在root下安装。
2、canal_deployer IP信息具体指定下。
3、canal admin password要和数据库一致。canal_deployer里的密码配置也需要配置正确。
密码生成方式，MySQL里执行如下语句：select password('xxx#canal')；
