a、安装说明（Linux Binaries）

使用 Linux Binaries 方式部署 Canal Server

参考：

https://github.com/alibaba/canal/wiki/QuickStart

下载 Canal Server 安装文件

从浏览器 或 命令行 下载最新稳定的 Canal Server 安装文件将其安装到系统中 $PATH。

注意：可先网页下载到本地，上传到 /usr/local/src 目录下，也可以使用 wget 下载；

访问 release 页面 , 选择需要的包下载, 如以 1.1.7 版本为例

https://github.com/alibaba/canal/releases

直接点击链接下载安装包

从命令行下载并安装（推荐）

• Standalone Linux Binaries (64 Bit)

$ cd /usr/local/src && wget https://github.com/alibaba/canal/releases/download/canal-1.1.7/canal.deployer-1.1.7.tar.gz --no-check-certificate
$ mkdir -p /usr/local/canal.deployer-1.1.7
$ cd /usr/local/src && tar zxf canal.deployer-1.1.7.tar.gz -C /usr/local/canal.deployer-1.1.7
$ cd .. && mv canal.deployer-1.1.7/ canal-server

解压完成后，进入 /usr/local/canal-server 目录，可以看到如下结构

drwxr-xr-x  2 root root 4096  5月 28 22:50 bin/
drwxr-xr-x  5 root root 4096  5月 28 22:50 conf/
drwxr-xr-x  2 root root 4096  5月 28 22:50 lib/
drwxrwxrwx  2 root root 4096  8月 11  2022 logs/
drwxrwxrwx  2 root root 4096  8月 11  2022 plugin/

快速启动 Canal Server

1. 配置修改

vi conf/example/instance.properties

# mysql serverId
canal.instance.mysql.slaveId = 1234
#position info，需要改成自己的数据库信息
canal.instance.master.address = 127.0.0.1:3306
#binlog日志名称
canal.instance.master.journal.name = mysql-bin.000001
# mysql主库链接时起始的binlog偏移量
canal.instance.master.position = 326513581
# mysql主库链接时起始的binlog的时间戳
canal.instance.master.timestamp =
#canal.instance.standby.address =
#canal.instance.standby.journal.name =
#canal.instance.standby.position =
#canal.instance.standby.timestamp =
#username/password，需要改成自己的数据库信息
canal.instance.dbUsername = canal
canal.instance.dbPassword = canal
canal.instance.defaultDatabaseName =
canal.instance.connectionCharset = UTF-8
#table regex
canal.instance.filter.regex = .\*\\\\..\*

• canal.instance.connectionCharset 代表数据库的编码方式对应到 java 中的编码类型，比如 UTF-8，GBK, ISO-8859-1
• 如果系统是 1 个 cpu，需要将 canal.instance.parser.parallel 设置为 false

2. 启动

sh bin/startup.sh

3. 查看 server 日志

tail -f logs/canal/canal.log

2013-02-05 22:45:27.967 [main] INFO  com.alibaba.otter.canal.deployer.CanalLauncher - ## start the canal server.
2013-02-05 22:45:28.113 [main] INFO  com.alibaba.otter.canal.deployer.CanalController - ## start the canal server[10.1.29.120:11111]
2013-02-05 22:45:28.210 [main] INFO  com.alibaba.otter.canal.deployer.CanalLauncher - ## the canal server is running now ......

4. 查看 instance 的日志

tail -f logs/example/example.log

2013-02-05 22:50:45.636 [main] INFO  c.a.o.c.i.spring.support.PropertyPlaceholderConfigurer - Loading properties file from class path resource [canal.properties]
2013-02-05 22:50:45.641 [main] INFO  c.a.o.c.i.spring.support.PropertyPlaceholderConfigurer - Loading properties file from class path resource [example/instance.properties]
2013-02-05 22:50:45.803 [main] INFO  c.a.otter.canal.instance.spring.CanalInstanceWithSpring - start CannalInstance for 1-example 
2013-02-05 22:50:45.810 [main] INFO  c.a.otter.canal.instance.spring.CanalInstanceWithSpring - start successful

5. 关闭

sh bin/stop.sh

创建 systemd 服务文件

创建 /etc/systemd/system/canal-server.service 服务文件

[root@local ~]# vi /lib/systemd/system/canal-server.service

脚本内容：

[Unit]
Description=Canal Server
Documentation=https://github.com/alibaba/canal/wiki/QuickStart
Wants=network-online.target
After=network-online.target

[Service]
User=root
Type=forking

ExecReload=/usr/local/canal-server/bin/restart.sh
# RPM Linux
#ExecRestart=/usr/local/canal-server/bin/restart.sh
Restart=on-failure
StartLimitInterval=60

[Install]
WantedBy=multi-user.target

设置随机启动：

[root@local ~]# systemctl daemon-reload
[root@local ~]# systemctl disable canal-server.service
[root@local ~]# systemctl enable canal-server.service
[root@local ~]# systemctl start canal-server.service
[root@local ~]# systemctl status canal-server.service
[root@local ~]# systemctl stop canal-server.service
[root@local ~]# systemctl restart canal-server.service
