#This script is used to download the connector plug-ins required during the running process. 
#All are downloaded by default. You can also choose what you need. 
#You only need to configure the plug-in name in config/plugin_config.

# get seatunnel home
SEATUNNEL_HOME=$(cd $(dirname $0);cd ../;pwd)

# connector default version is 2.3.8, you can also choose a custom version. eg: 2.3.8:  sh install-plugin.sh 2.3.8

done < ${SEATUNNEL_HOME}/config/plugin_config

配置 SeaTunnel 同步作业​

编辑 config/v2.batch.config.template 文件，该文件决定了在启动 SeaTunnel 后数据输入、处理和输出的方式及逻辑。

配置文件示例:

# 环境配置
env {
  # 指定任务是批模式还是流模式，job.mode = "BATCH"为批模式，job.mode = "STREAMING"为流模式
  parallelism = 2
  job.mode = "BATCH"
  checkpoint.interval = 10000
}

# 数据源
source {
  # 定义SeaTunnel从哪里获取数据。支持同时配置多个源，每个源都有特有的参数用于定义如何获取数据。
  FakeSource {
    parallelism = 2
    result_table_name = "fake"
    row.num = 16
    schema = {
      fields {
        name = "string"
        age = "int",
        card = "int"
      }
    }
  }
}

# 转换器
transform {
  Filter {
    source_table_name = "fake"
    result_table_name = "fake1"
    fields = [name, card]
  }
}

# 写入
sink {
  Console {
    source_table_name = "fake1"
  }
}

运行seatunnel服务​

测试验证seatunnel​

进入seatunnel后台服务目录

cd /opt/bigdata/seatunnel-2.3.8/backend/apache-seatunnel-2.3.8

启动服务

./bin/seatunnel.sh --config ./config/v2.batch.config.template -e local

启动seatunnel服务​

进入seatunnel后台服务目录

cd /opt/bigdata/seatunnel-2.3.8/backend/apache-seatunnel-2.3.8

启动服务

nohup sh bin/seatunnel-cluster.sh 2>&1 &

查询启动日志

tail -f /opt/bigdata/seatunnel-2.3.8/backend/apache-seatunnel-2.3.8/logs/seatunnel-engine-server.log

安装seatunnel-web​

进入seatunnel-web服务目录

cd /opt/bigdata/seatunnel-2.3.8/web/apache-seatunnel-web-1.0.2/

初始化数据库​

注意：下面这步要提前装好mysql（mysql>= 5.7.28），如果没有装干脆直接取script/seatunnel_server_mysql.sql到自己的mysql服务器上导入，后面配置从localhost改到自己的服务器

编辑seatunnel_server_env.sh文件，修改数据库地址、端口、账户、密码，并修改配置加上前缀STWEB_

workDir=`dirname $0`
workDir=`cd ${workDir};pwd`

source ${workDir}/seatunnel_server_env.sh

usage="Usage: seatunnel_server_env.sh must contain hostname/port/username/password."

if [[ ! -n "${STWEB_HOSTNAME}" ]]  || [[ ! -n "${STWEB_PORT}" ]] || [[ ! -n "${STWEB_USERNAME}" ]] || [[ ! -n "${STWEB_PASSWORD}" ]]; then
    echo $usage
    exit 1
fi

mysql -h${STWEB_HOSTNAME} -P${STWEB_PORT} -u${STWEB_USERNAME} -p${STWEB_PASSWORD} < ${workDir}/seatunnel_server_mysql.sql

执行初始化数据库命令

sh script/init_sql.sh

修改端口与数据源​

修改端口号和数据源信息

vim conf/application.yml

注：必须填写secretKey

配置client信息

将seatunnel引擎服务节点的安装目录下的config目录下的关于引擎客户端的配置文件拷贝到seatunnel-web安装目录下的conf目录下 同一台机器下部署直接使用以下拷贝命令(注意修改服务的安装目录为你自己的安装目录)

sudo cp /opt/bigdata/seatunnel-2.3.8/backend/apache-seatunnel-2.3.8/config/hazelcast-client.yaml /opt/bigdata/seatunnel-2.3.8/web/apache-seatunnel-web-1.0.2/conf

如果不在同一台机器上， 可以使用scp命令或者下载下来然后上传到web服务的安装主机的安装目录下的conf目录下即可。

配置支持的插件信息

将seatunnel引擎服务节点的安装目录下的connectors目录下的plugin-mapping.properties配置文件拷贝到seatunnel-web安装目录下的conf目录下

sudo cp /opt/bigdata/seatunnel-2.3.8/backend/apache-seatunnel-2.3.8/connectors/plugin-mapping.properties /opt/bigdata/seatunnel-2.3.8/web/apache-seatunnel-web-1.0.2/conf

同一台机器下部署直接使用以下拷贝命令(注意修改服务的安装目录为你自己的安装目录)如果不在同一台机器上， 可以使用scp命令或者下载下来然后上传到web服务的安装主机的安装目录下的conf目录下即可。

下载jar包​

在线下载jar包，存在datasource文件夹

sh /opt/bigdata/seatunnel-2.3.8/web/apache-seatunnel-web-1.0.2/bin/download_datasource.sh

下载mysql-connector-j-8.3.0.jar包，并放到/opt/bigdata/seatunnel-2.3.8/web/apache-seatunnel-web-1.0.2/libs 下 地址：https://downloads.mysql.com/archives/c-j/

cp -r mysql-connector-j-8.3.0.jar /opt/bigdata/seatunnel-2.3.8/web/apache-seatunnel-web-1.0.2/libs

启动seatunnel-web服务​

cd /opt/bigdata/seatunnel-2.3.8/web/apache-seatunnel-web-1.0.2
sh bin/seatunnel-backend-daemon.sh start

# 停止
sh bin/seatunnel-backend-daemon.sh stop

# 查询状态
sh bin/seatunnel-backend-daemon.sh status

访问地址​

Url:http://localhost:8081 账户：admin 密码：admin

未解决问题​

额，访问是可以访问了，但是有个bug，选择整库同步时选不出来source，真的是奇葩

全拷贝到lib也无效

cp -r /opt/bigdata/seatunnel-2.3.8/web/apache-seatunnel-web-1.0.2/datasource/* /opt/bigdata/seatunnel-2.3.8/web/apache-seatunnel-web-1.0.2/libs
