启动项目
/opt/operation/canal/canaladapter/bin/startup.sh
查看同步情况
文章图片
首先连接到linux,切换至root用户
使用canal要先开启mysql的Binlog写入功能,配置 binlog-format 为ROW模式,故须使用如下命令修改mysql的my.cnf中配置
vi /etc/my.cnf
启动 canal-admin 命令
/opt/operation/canal/canaladmin/bin/startup.sh
在my.cnf配置中加入以下配置
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binlog-ignore-db=information_schema
binlog-ignore-db=mysql
binlog-ignore-db=performance_schema
binlog-ignore-db=sys#验证
show variables like 'log_bin%';
#log_bin ON
show variables like 'binlog_format%';
#binlog_format ROWlog-bin用于指定binlog日志文件名前缀,默认存储在/var/lib/mysql 目录下。
server-id用于标识唯一的数据库,不能和别的服务器重复,建议使用ip的最后一段,默认值也不可以。
binlog-ignore-db:表示同步的时候忽略的数据库。
binlog-do-db:指定需要同步的数据库(如果没有此项,表示同步所有的库)。

添加配置并保存后,使用如下命令重启mysql服务
service mysql restart
文章图片
重启服务之后,进入mysql命令行新增并授权 canal 链接 mysql账号具有作为 mysql slave 的权限
CREATE USER canal IDENTIFIED BY 'canal';
GRANT SELECT, REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO 'canal'@'%';
FLUSH PRIVILEGES;
alter user 'canal'@'%' identified with mysql_native_password by 'canal';
文章图片
配置好好mysql之后,进入到usr/local目录下,在该目录下使用如下命令新建canal文件夹
cd /usr/local
ls
mkdir canal
使用如下命令给文件夹授权
//给local赋予读写权限
chmod 777 canal
//给local及其以下子目录赋予读写权限
chmod -R 777 canal
赋权成功后,使用Xftp将下载好的压缩包传输到canal目录下
进入/usr/local/canal目录查看压缩包是否存在,存在则使用如下命令解压压缩包
cd /usr/local/canal
ls
tar -zxvf canal.deployer-1.1.6.tar.gz
解压完后会多出几个目录
bin conf lib logs
根据之前创建的用户修改conf/下的canal.properties配置文件,主要是修改与mysql相关的配置,其余基本不变,修改完成后
修改配置文件 cd conf/
vi canal.properties
按实际情况填写
canal.instance.dbUsername = canal #数据库用户名
canal.instance.dbPassword = canal #数据库密码
canal.instance.defaultDatabaseName = datacenter #指定需要同步的数据库
canal.instance.connectionCharset = UTF-8 #指定编码方式#1. 所有表:.* or .*\\..*
#2. canal schema下所有表: canal\\..*
#3. canal下的以canal打头的表:canal\\.canal.*
#4. canal schema下的一张表:canal.test1
#5. 多个规则组合使用:canal\\..*,mysql.test1,mysql.test2 (逗号分隔)保存并退出
cd到bin目录下使用如下命令启动canal
./startup.sh
启动后,使用以下命令查看是否启动成功
ps -ef | grep canal
或
观察canal日志:
tail -n 50 /home/hadoop/test/lele/canal/logs/canal/canal.log
没有错误则表示启动正常
至此,canal启动成功
若需要看canal的日志,则cd到log目录下查看即可
canal server的默认端口为:11111,若需要修改,可以去conf目录下的canal.properties配置文件中进行修改
客户端想连接canal服务端还需开放linux防火墙的11111端口
//开启端口
firewall-cmd --zone=public --add-port=11111/tcp --permanent
//查询端口号11111是否开启:
firewall-cmd --query-port=11111/tcp
//重启防火墙:
firewall-cmd --reload
//查询有哪些端口是开启的:
firewall-cmd --list-port
//禁用端口
firewall-cmd --zone=public --remove-port=11111/tcp --permanent
