背景
canal-admin设计上是为canal提供整体配置管理、节点运维等面向运维的功能,提供相对友好的WebUI操作界面,方便更多用户快速和安全的操作
准备
canal-admin的限定依赖:
- MySQL,用于存储配置和节点等相关数据
- canal版本,要求>=1.1.4 (需要依赖canal-server提供面向admin的动态运维管理接口)
部署
下载 canal-admin, 访问 release 页面 , 选择需要的包下载, 如以 1.1.4 版本为例
wget https://github.com/alibaba/canal/releases/download/canal-1.1.4/canal.admin-1.1.4.tar.gz
解压缩
mkdir /tmp/canal-admin
tar zxvf canal.admin-$version.tar.gz -C /tmp/canal-admin
解压完成后,进入 /tmp/canal 目录,可以看到如下结构
drwxr-xr-x 6 agapple staff 204B 8 31 15:37 bin
drwxr-xr-x 8 agapple staff 272B 8 31 15:37 conf
drwxr-xr-x 90 agapple staff 3.0K 8 31 15:37 lib
drwxr-xr-x 2 agapple staff 68B 8 31 15:26 logs
配置修改
vi conf/application.yml

- 初始化元数据库 ``` mysql -h127.1 -uroot -p
导入初始化SQL
source conf/canal_manager.sql ```
a. 初始化SQL脚本里会默认创建canal_manager的数据库,建议使用root等有超级权限的账号进行初始化 b. canal_manager.sql默认会在conf目录下,也可以通过链接下载 canal_manager.sql
- 启动
查看 admin 日志 ``` vi logs/admin.logsh bin/startup.sh
2019-08-31 15:43:38.162 [main] INFO o.s.boot.web.embedded.tomcat.TomcatWebServer - Tomcat initialized with port(s): 8089 (http) 2019-08-31 15:43:38.180 [main] INFO org.apache.coyote.http11.Http11NioProtocol - Initializing ProtocolHandler [“http-nio-8089”] 2019-08-31 15:43:38.191 [main] INFO org.apache.catalina.core.StandardService - Starting service [Tomcat] 2019-08-31 15:43:38.194 [main] INFO org.apache.catalina.core.StandardEngine - Starting Servlet Engine: Apache Tomcat/8.5.29 …. 2019-08-31 15:43:39.789 [main] INFO o.s.w.s.m.m.annotation.ExceptionHandlerExceptionResolver - Detected @ExceptionHandler methods in customExceptionHandler 2019-08-31 15:43:39.825 [main] INFO o.s.b.a.web.servlet.WelcomePageHandlerMapping - Adding welcome page: class path resource [public/index.html]
此时代表canal-admin已经启动成功,可以通过 http://127.0.0.1:8089/ 访问,默认密码:admin/123456

6. 关闭
sh bin/stop.sh
7. canal-server端配置
使用canal_local.properties的配置覆盖canal.properties
register ip
canal.register.ip =
canal admin config
canal.admin.manager = 127.0.0.1:8089 canal.admin.port = 11110 canal.admin.user = admin canal.admin.passwd = 4ACFE3202A5FF5CF467898FC58AAB1D615029441
admin auto register
canal.admin.register.auto = true canal.admin.register.cluster = ``` 启动admin-server即可。
或在启动命令中使用参数:sh bin/startup.sh local 指定配置
just have fun!
