启动步骤：
-1. 下载canal
-直接下载
-访问：https://github.com/alibaba/canal/releases ，会列出所有历史的发布版本包 -下载方式，比如以1.0.17版本为例子： -wget https://github.com/alibaba/canal/releases/download/canal-1.0.17/canal.deployer-1.0.17.tar.gz-
or
-自己编译
-git clone git@github.com:alibaba/canal.git -cd canal; -mvn clean install -Dmaven.test.skip -Denv=release-
编译完成后，会在根目录下产生target/canal.deployer-$version.tar.gz
--
2. 解压缩
-mkdir /tmp/canal -tar zxvf canal.deployer-$version.tar.gz -C /tmp/canal-
-
解压完成后，进入/tmp/canal目录，可以看到如下结构：
