主要包有:
canal.adapter-1.1.6.tar.gz
canal.admin-1.1.6.tar.gz
canal.deployer-1.1.6.tar.gz
包下载地址: https://github.com/alibaba/canal/releases
1.3:分发这些包至|docker1|docker2|主机
使用Xshell客户端控制同时控制|docker0|docker1|docker2|主机
在docker0主机上执行创建响应目录
[root@www canal]# mkdir -p /usr/local/canal/adapter
[root@www canal]# mkdir -p /usr/local/canal/admin
[root@www canal]# mkdir -p /usr/local/canal/deployerdocker0主机执行命令完成,则其他机器会同步创建这些目录
关闭docker1|docker2主机上的Xshell同步开发置为off,暂停同步操作
在docker0主机上分发对应安装包到docker1|docker2主机对应目录:/usr/local/tools/
[root@www tools]# scp canal.adapter-1.1.6.tar.gz canal.admin-1.1.6.tar.gz canal.deployer-1.1.6.tar.gz docker1:/usr/local/tools/
[root@www tools]# scp canal.adapter-1.1.6.tar.gz canal.admin-1.1.6.tar.gz canal.deployer-1.1.6.tar.gz docker2:/usr/local/tools/
[root@www canal]# cd /usr/local/tools

没有发现8888这个端口进程,启动失败,看日志该异常:由于装的数据库时8.0.30,该jar版本低了,上传高版本的mysql驱动包:mysql-connector-java-8.0.30.jar
[root@www lib]# find ./ -name mysq*
./mysql-connector-java-8.0.30.jar再次重启:

这个是数据库加密升级原因;
MySQL8.xx 解决1251 client does not support ..解决方案 参考这篇文章解决
创建一个canal账号及密码: canal
CREATE USER 'canal'@'%' IDENTIFIED WITH mysql_native_password BY 'canal';
再次启动:
[root@www logs]# tail -f admin.log
Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [io.ebean.EbeanServer]: Factory method 'ebeanServer' threw exception; nested exception is javax.persistence.PersistenceException: java.sql.SQLNonTransientConnectionException: Public Key Retrieval is not allowed

[root@www lib]# find ./ -name Hikari*
./HikariCP-2.7.8.jar
Access denied for user 'canal'@'%' to database 'canal_manager'这个异常一般没权限: canal 用户没权限访问数据库canal_manager
UPDATE mysql.user SET Grant_priv='Y', Super_priv='Y' WHERE User='canal';
GRANT INSERT ON canal_cluster TO 'canal'@'%'
GRANT INSERT ON canal_config TO 'canal'@'%'
flush privileges;
解决方案:
canal报错,解决方法,将数据库切到canal_manager,使用以下命令即可
GRANT INSERT ON canal_node_server TO 'canal'@'%'
同样新增集群也会报这个错,类似命令:
GRANT INSERT ON canal_cluster TO 'canal'@'%'
模板保存也是
GRANT INSERT ON canal_config TO 'canal'@'%'
使用local启动的时候要创建相应的模板。
查看日志启动成功:
[root@www logs]# ps aux | grep 'canal'
[root@www logs]# netstat -lntp | grep 8888
