使用canal1.1.5让MySQL5.7同步到ES7.x

哎！也算是记录自己的踩坑日记吧
注意： MySQL和ES7请自己自行安装好，请大家一定确定自己MySQL的版本。
使用的系统：Centos，Ubuntu。windows请移步

# 这里的版本不能低于5.7， 如果小于5.7的请移步，使用8的也请移步
SELECT VERSION();

好，步入正文

MySQL配置

1.设置MySQL

# 使用已有的账号和密码登录
myql -u root -p
# CREATE USER 用户名 IDENTIFIED BY '密码';
CREATE USER canal IDENTIFIED BY 'canal';  # 赋予权限
GRANT SELECT, REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO 'canal'@'%';
-- GRANT ALL PRIVILEGES ON *.* TO 'canal'@'%' ;# 刷新权限
FLUSH PRIVILEGES;

2.设置binlog

使用yum安装的，文件位置大概都是这个/etc/my.cnf
所以请 vim /etc/my.cnf

[mysqld]
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！如果相把日志单独放的朋友请一定设置权限，好吧！如
log-bin=/usr/local/mysql/binlogs/mysql-bin # 开启 binlog
chown -R mysql:mysql  /usr/local/mysql/binlogs # 设置权限mysql> show variables like 'binlog_format%';       #查看binlog模式，如果显示如下，就说明成功了
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| binlog_format | ROW   |
+---------------+-------+
1 row in set (0.06 sec)

# 创建数据库
create database `fgn-user` character set utf8;# 创建表
CREATE TABLE `users` (  `id` int(11) NOT NULL,`age` int(11) NOT NULL,`name` varchar(200) NOT NULL,`address` varchar(1000) DEFAULT NULL,`created_at` datetime DEFAULT NULL,`updated_at` datetime DEFAULT NULL,`deleted_at` datetime DEFAULT NULL,PRIMARY KEY (id)) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

部署Canal-deployer服务端

1.下载并解压

wget https://github.com/alibaba/canal/releases/download/canal-1.1.5-alpha-1/canal.deployer-1.1.5-SNAPSHOT.tar.gz
#如果下载不下来，试试看我保存的
wget https://file.hytwfy.top/canal.deployer-1.1.5-SNAPSHOT.tar.gz
mkdir /usr/local/canal-deployer
tar xf canal.deployer-1.1.5-SNAPSHOT.tar.gz -C /usr/local/canal-deployer/

2.修改配置文件

# 如果前面和我设置路径一样的话，就直接复制吧，如果不是请使用自己的
[root@wfy]# vim /usr/local/canal-deployer/conf/example/instance.properties
## mysql serverId , v1.0.26+ will autoGen
canal.instance.mysql.slaveId=3     #修改ID，不能和MySQL数据库一致# enable gtid use true/false

canal.instance.master.position=
canal.instance.master.timestamp=
canal.instance.master.gtid=# rds oss binlog
canal.instance.rds.accesskey=
canal.instance.rds.secretkey=
canal.instance.rds.instanceId=# table meta tsdb info
canal.instance.tsdb.enable=true
#canal.instance.tsdb.url=jdbc:mysql://127.0.0.1:3306/canal_tsdb
#canal.instance.tsdb.dbUsername=canal
#canal.instance.tsdb.dbPassword=canal#canal.instance.standby.address =
#canal.instance.standby.journal.name =
#canal.instance.standby.position =
#canal.instance.standby.timestamp =
#canal.instance.standby.gtid=# username/password
canal.instance.dbUsername=canal    #MySQL账号
canal.instance.dbPassword=canal    #MySQL密码
canal.instance.connectionCharset = UTF-8    #字符集格式，需要与mysql保持一致
# enable druid Decrypt database password
canal.instance.enableDruid=false
#canal.instance.pwdPublicKey=MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBALK4BUxdDltRRE5/zXpVEVPUgunvscYFtEip3pmLlhrWpacX7y7GCMo2/JM6LeHmiiNdH1FWgGCpUfircSwlWKUCAwEAAQ==# table regex

#canal.mq.dynamicTopic=mytest1.user,mytest2\\..*,.*\\..*
canal.mq.partition=0
# hash partition config
#canal.mq.partitionsNum=3
#canal.mq.partitionHash=test.table:id^name,.*\\..*
#canal.mq.dynamicTopicPartitionNum=test.*:4,mycanal:6

3.启动canal-deployer
因为canal-depaloyer由java开发，所以需要jdk环境，jdk版本使用1.8

yum install java-1.8.0-openjdk.x86_64 java-1.8.0-openjdk-devel.x86_64 -y
/usr/local/canal-deployer/bin/startup.sh

4.查看日志及端口

[root@wfy]# ss -anplt | grep java
LISTEN     0      50           *:11110                    *:*                   users:(("java",pid=7577,fd=91))
LISTEN     0      50           *:11111                    *:*                   users:(("java",pid=7577,fd=87))
LISTEN     0      3            *:11112                    *:*                   users:(("java",pid=7577,fd=70))
LISTEN     0      100          *:8081                     *:*                   users:(("java",pid=7657,fd=109))

部署Canal-adapter客户端

1.下载并解压

wget https://github.com/alibaba/canal/releases/download/canal-1.1.5-alpha-1/canal.adapter-1.1.5-SNAPSHOT.tar.gz
#如果下载不下来，试试看我保存的
wget https://file.hytwfy.top/canal.adapter-1.1.5-SNAPSHOT.tar.gz
mkdir /usr/local/canal-adapter
tar xf canal.adapter-1.1.5-SNAPSHOT.tar.gz -C /usr/local/canal-adapter/

2.修改application.yml

[root@wfy]# vim /usr/local/canal-adapter/conf/application.yml

#          properties:
#            kudu.master.address: 127.0.0.1 # ',' split multi address

3.修改适配器映射文件

[root@wfy]#vim /usr/local/canal-adapter/conf/es7/mytest_user.ymldataSourceKey: defaultDS   #指定在application.yml文件中srcDataSources源数据源自定义的名称
outerAdapterKey: fgnKey    #和上面的配置文件的key一致。
destination: example
groupId: g1
esMapping:_index: fgn-article     #指定索引名称_id: _id            #指定文档id，_id 此值则由es自动分配文档ID
#  upsert: true
#  pk: idsql: "select id as _id, user_id, title, content, issue_time, created_at, updated_at, deleted_at from article_profiles"   # 这里请特别注意，写成这个样子默认的是bug。。。
#  objFields:
#rticle    _labels: array:;
#  etlCondition: "where a.c_time>={}"commitBatch: 3000

**4.在ES7创建相对应的mapping

#    建议把索引设置成为和数据库名一样
PUT /fgn-user
{"mappings": {"properties": {"created_at": {"type": "date"},"deleted_at": {"type": "date"}"updated_at": {"type": "date"},"age": {"type": "keyword"},"address": {"type": "text"}}}
}

5.启动Canal-adapter并写入数据

/usr/local/canal-adapter/bin/startup.shtail -f /usr/local/canal-adapter/logs/adapter/adapter.log
# 如果这个不存在，请回到/usr/local/canal-adapter/bin/查看错误
cd /usr/local/canal-adapter/bin
