connector-console-2.3.3.jar  connector-fake-2.3.3.jar

安装seatunnel过程中，解压文件后官方默认提供的connector的jar包只有2个，要想连接mysql，oracle，SqlServer，hive，kafka，clickhouse，doris等时，还需下载对应的jar包。

下载插件

使用本地Maven加速下载connector相关jar包

seatunnel下载connector的jar时，使用mvnw来下载jar包，默认是从https://repo.maven.apache.org 下载，速度及其缓慢。

我们可以改成自己在linux系统上安装的mvn，配置阿里云远程仓库地址，从阿里云mvn源下载会快很多，下面教大家如何进行修改。

备份 install-plugin.sh 重命名为install-plugin.sh.bak

  [bash]
1
cp install-plugin.sh install-plugin.sh.bak

修改文件之前，记得备份。养成好习惯。

修改 install-plugin.sh

替换脚本中的 ${SEATUNNEL_HOME}/mvnw 为 mvn，即可使用本地mvn，配合阿里云的mvn源，可加速下载。

我们操作了这么多，只是为了下载驱动包而已。

驱动包下载地址

也可以手动下载对应的包，分别放在上面 2 个目录中。

PS：不过这里的 maven 其他依赖包怎么处理？

必须保证Apache SeaTunnel的Server正常运行，Web端服务才能正常运行。

3. 安装 web 端

3.1 安装配置Seatunnel引擎集群

在SeaTunnel的Web端机器上需要安装SeaTunnel客户端，如果服务端与Web端在同一台机器，则可直接跳过这个步骤。

本文档的安装过程中，Seatunnel服务端和web是安装在同一台机器上，所以直接跳过此步安装步骤。

这里所说的Seatunnel引擎客户端其实就是我们章2中安装的Seatunnel服务端，下面讲解一下如何进行Seatunnel集群的安装配置

3.1.1.准备服务器节点

我们现在需要搭建Seatunnel引擎集群，需要准备 n 台服务器节点，我这里使用了3台服务器。

比如，已知我们的3台服务器的IP分别是

  [plaintext]
1
2
3
192.168.1.110
192.168.1.111
192.168.1.112

我们直接在章2中已经安装部署好的Seatunnel单节点中进行集群的配置,主要的配置修改包含以下几项：

3.1.2.修改JVM参数

在seatunnel的安装目录，找到 $SEATUNNEL_HOME/bin/seatunnel-cluster.sh

jvm

将 JVM 选项添加到$SEATUNNEL_HOME/bin/seatunnel-cluster.sh第一行

  [plaintext]
1
JAVA_OPTS="-Xms2G -Xmx2G"

如果不想这样进行修改，也可以，不过需要在进行集群启动时，自行增加JVM参数进行启动，启动命令如下：

  [bash]
1
nohup sh $SEATUNNEL_HOME/bin/seatunnel-cluster.sh -DJvmOption="-Xms2G -Xmx2G" 2>&1 &

config

3.1.3.SeaTunnel Engine配置

SeaTunnel Engine Server配置是在sh $SEATUNNEL_HOME/config/seatunnel.yaml .

详细配置想可参考官方文档 4. Config SeaTunnel Engine，这里不赘述

3.1.4.SeaTunnel Engine Server配置

SeaTunnel Engine Server配置是在sh $SEATUNNEL_HOME/config/hazelcast.yaml .

3.1.4.1.集群名称配置

SeaTunnel Engine 节点使用集群名称来确定对方是否与自己是一个集群。如果两个节点之间的集群名称不同，SeaTunnel 引擎将拒绝服务请求。

3.1.4.2.网络配置

SeaTunnel Engine 集群基于 Hazelcast，是运行 SeaTunnel Engine Server 的集群成员的网络。

集群成员自动连接在一起形成集群。这种自动加入是通过集群成员用来查找彼此的各种发现机制来实现的。

请注意，集群形成后，集群成员之间的通信始终通过 TCP/IP 进行，无论使用何种发现机制。

SeaTunnel 引擎使用以下发现机制。

TCP

您可以将 SeaTunnel Engine 配置为完整的 TCP/IP 集群。有关配置详细信息，请参阅通过 TCP 发现成员部分。

hazelcast.yaml配置示例如下：

  [yaml]
1
2
3
4
5
6
7
8
9
10
11
12
13
hazelcast:
  cluster-name: seatunnel
  network:
    join:
      tcp-ip:
        enabled: true
        member-list:
          - hostname1
    port:
      auto-increment: false
      port: 5801
  properties:
    hazelcast.logging.type: log4j2

在独立 SeaTunnel 引擎集群中我们建议使用TCP方式。

另一方面，Hazelcast 提供了一些其他的服务发现方法。详情请参考hazelcast网

3.1.4.3 Map配置

type

imap持久化类型，目前仅支持hdfs。

namespace

命令空间用于区分不同业务的数据存储位置，例如OSS的桶名。

clusterName

这个参数主要用于集群隔离，我们可以通过这个来区分不同的集群，比如cluster1、cluster2，这个也可以用来区分不同的业务

fs.defaultFS

We used hdfs api read/write file, so used this storage need provide hdfs configuration

if you used HDFS, you can config like this:

  [yaml]
1
2
3
4
5
6
7
8
9
10
11
12
map:
    engine*:
       map-store:
         enabled: true
         initial-mode: EAGER
         factory-class-name: org.apache.seatunnel.engine.server.persistence.FileMapStoreFactory
         properties:
           type: hdfs
           namespace: /tmp/seatunnel/imap
           clusterName: seatunnel-cluster
           storage.type: hdfs
           fs.defaultFS: hdfs://localhost:9000

如果没有 HDFS 并且您的集群只有一个节点，您可以配置为使用本地文件，如下所示：

  [yaml]
1
2
3
4
5
6
7
8
9
10
11
12
map:
    engine*:
       map-store:
         enabled: true
         initial-mode: EAGER
         factory-class-name: org.apache.seatunnel.engine.server.persistence.FileMapStoreFactory
         properties:
           type: hdfs
           namespace: /tmp/seatunnel/imap
           clusterName: seatunnel-cluster
           storage.type: hdfs
           fs.defaultFS: file:///

如果你使用OSS，你可以这样配置：

  [yaml]

         factory-class-name: org.apache.seatunnel.engine.server.persistence.FileMapStoreFactory
         properties:
           type: hdfs
           namespace: /tmp/seatunnel/imap
           clusterName: seatunnel-cluster
           storage.type: oss
           block.size: block size(bytes)
           oss.bucket: oss://bucket name/
           fs.oss.accessKeyId: OSS access key id
           fs.oss.accessKeySecret: OSS access key secret
           fs.oss.endpoint: OSS endpoint
           fs.oss.credentials.provider: org.apache.hadoop.fs.aliyun.oss.AliyunCredentialsProvider

3.1.5.SeaTunnel Engine Client配置

SeaTunnel Engine Client配置是在sh $SEATUNNEL_HOME/config/hazelcast-client.yaml .

3.1.5.1.集群名称配置

客户端必须与 SeaTunnel 引擎具有相同的集群名称。否则，SeaTunnel 引擎将拒绝客户端请求。

3.1.5.2. 网络配置

cluster-members

所有 SeaTunnel 引擎服务器节点地址都需要添加到此处。

  [yaml]
1
2
3
4
5
6
7
hazelcast-client:
  cluster-name: seatunnel
  properties:
      hazelcast.logging.type: log4j2
  network:
    cluster-members:
      - hostname1:5801

3.1.6.启动Seatunnel引擎服务端节点

  [bash]
1
2
3
4
5
mkdir -p $SEATUNNEL_HOME/logs

cd $SEATUNNEL_HOME

./bin/seatunnel-cluster.sh -d

如果集群存在多台节点，需要启动所有节点上的Seatunnel引擎服务。

3.1.7.安装Seatunnel引擎客户端并启动

您只需将SeaTunnel引擎节点上的安装目录目录复制到客户端节点主机的相同安装目录下，并像SeaTunnel引擎服务器节点一样配置SEATUNNEL_HOME，之后启动服务即可。

3.2.配置Seatunnel Web服务

3.2.1.数据库初始化

3.2.1.1.修改数据库连接配置

将script/seatunnel_server_env.sh相关配置改为你的对应的数据库信息

脚本配置在 web 目录下

3.2.3.下载配置数据源JAR包

这一步非常关键，这一步如果没有配置好，即使你正常启动了web应用，可能也会遇到下列问题：

数据源类型选择页面为空，我这里因为正常配置，所以正常显示

config

没有Source或者Sink进行选择

select

任务无法正常执行

3.2.3.1.获取下载脚本

数据源JAR包的下载脚本在 seatunnel-web 的源码包中存在，它的目录在：

下载脚本

我们访问官方代码：

https://github.com/apache/seatunnel-web 源码

  [bash]
1
git clone git@github.com:apache/seatunnel-web.git

也可以直接访问

https://github.com/apache/seatunnel-web/blob/main/seatunnel-server/seatunnel-app/src/main/bin/download_datasource.sh

说白了就是在指定的目录下载对应的包。

3.2.3.2.执行下载脚本

我们把上面的下载脚本修改一下：

我们把下载目录改成：

1) DATASOURCE_DIR=/home/dh/bigdata/seatunnel-2.3.3/jars，然后在 linux 机器上创建这个下载脚本。

2) 使用 mvn 命令下载，替代原来的 mvnw

  [plaintext]
1
mvn dependency:get -DgroupId=org.apache.seatunnel -DartifactId="$i" -Dversion="$version" -Ddest="$DATASOURCE_DIR"

完整如下：

发现这里就是没有 mongodb

https://repo.maven.apache.org/maven2/org/apache/seatunnel/

3.2.3.3. 下载额外的 mysql 包

我们在 /home/dh/bigdata/seatunnel-2.3.3/jars/ 中额外下载一个 mysql 8.0 的启动包。

https://dev.mysql.com/downloads/connector/j/

1) maven 方式

  [xml]
1
2
3
4
5
<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>8.0.23</version> <!-- 这里使用你需要的具体版本号 -->
</dependency>

https://mvnrepository.com/artifact/mysql/mysql-connector-java

实际上这个项目迁移到了 https://github.com/mysql/mysql-connector-j

2）jar 的地址

手动下载后上传，huozhe直接：

  [sh]
1
2
cd /home/dh/bigdata/seatunnel-2.3.3/jars/
wget https://repo1.maven.org/maven2/com/mysql/mysql-connector-j/8.2.0/mysql-connector-j-8.2.0.jar

3.2.3.4. 复制到对应的目录

1）将以上所有jar包复制到 /home/dh/bigdata/seatunnel-2.3.3/web/apache-seatunnel-web-1.0.0/libs 目录下

  [bash]
1
cp /home/dh/bigdata/seatunnel-2.3.3/jars/* /home/dh/bigdata/seatunnel-2.3.3/web/apache-seatunnel-web-1.0.0/libs

确认：

  [bash]
1
cd /home/dh/bigdata/seatunnel-2.3.3/web/apache-seatunnel-web-1.0.0/libs

2）将以上所有jar包复制到 /home/dh/bigdata/seatunnel-2.3.3/backend/apache-seatunnel-2.3.3/lib 目录下

  [bash]
1
cp /home/dh/bigdata/seatunnel-2.3.3/jars/* /home/dh/bigdata/seatunnel-2.3.3/backend/apache-seatunnel-2.3.3/lib

3.2.5.启动WEB服务

所以启动服务必须要保证服务可以访问到ui目录下的index.html文件才可以，因为项目启动前端的项目路径默认添加了/ui的前缀，所以后端项目的启动路径必须在ui目录的父级目录才可以，所以这里需要再web服务的安装目录下执行启动脚本，举例：

我这里的安装目录是 /home/dh/bigdata/seatunnel-2.3.3/web/apache-seatunnel-web-1.0.0, 所以我这里直接切换到该目录下，执行以下启动命令：

  [sh]
1

#进入web服务的安装目录
cd /home/dh/bigdata/seatunnel-2.3.3/web/apache-seatunnel-web-1.0.0
#执行启动脚本
chmod +x ./bin/seatunnel-backend-daemon.sh

./bin/seatunnel-backend-daemon.sh start

这里应该是包冲突了。

该异常表明在使用 Seatunnel 时，发生了版本不兼容的问题，涉及到 Jetty 的相关类 org.eclipse.jetty.servlet.ServletHandler 和 org.eclipse.jetty.http.pathmap.PathMappings。

在你的异常信息中，有两个不同的 Jar 文件提供了 org.eclipse.jetty.servlet.ServletHandler 类，一个是 datasource-hive-1.0.0.jar，另一个是 jetty-servlet-9.4.46.v20220331.jar。这可能导致类加载的混淆和不一致性。

集群配置

3.1.安装配置Seatunnel引擎集群

在SeaTunnel的Web端机器上需要安装SeaTunnel客户端，如果服务端与Web端在同一台机器，则可直接跳过这个步骤。

本文档的安装过程中，Seatunnel服务端和web是安装在同一台机器上，所以直接跳过此步安装步骤。

这里所说的Seatunnel引擎客户端其实就是我们章2中安装的Seatunnel服务端，下面讲解一下如何进行Seatunnel集群的安装配置

3.1.1.准备服务器节点

我们现在需要搭建Seatunnel引擎集群，需要准备n台服务器节点，我这里使用了3台服务器。

比如，已知我们的3台服务器的IP分别是

  [plaintext]
1
2
3
4
5
192.168.1.110

192.168.1.111

192.168.1.112

我们直接在章2中已经安装部署好的Seatunnel单节点中进行集群的配置,主要的配置修改包含以下几项：

3.1.2.修改JVM参数

在seatunnel的安装目录，找到 $SEATUNNEL_HOME/bin/seatunnel-cluster.sh

jvm

将 JVM 选项添加到$SEATUNNEL_HOME/bin/seatunnel-cluster.sh第一行

  [sh]
1
JAVA_OPTS=“-Xms2G -Xmx2G”

如果不想这样进行修改，也可以，不过需要在进行集群启动时，自行增加JVM参数进行启动，启动命令如下：

也可以用这种方式启动：

  [sh]
1
nohup sh $SEATUNNEL_HOME/bin/seatunnel-cluster.sh -DJvmOption="-Xms2G -Xmx2G" 2>&1 &

配置文件

3.1.3.SeaTunnel Engine配置

SeaTunnel Engine Server配置是在sh $SEATUNNEL_HOME/config/seatunnel.yaml .

详细配置想可参考官方文档 4. Config SeaTunnel Engine，这里不赘述

3.1.4.SeaTunnel Engine Server配置

SeaTunnel Engine Server配置是在 sh $SEATUNNEL_HOME/config/hazelcast.yaml .

3.1.4.1.集群名称配置

SeaTunnel Engine 节点使用集群名称来确定对方是否与自己是一个集群。

如果两个节点之间的集群名称不同，SeaTunnel 引擎将拒绝服务请求。

3.1.4.2.网络配置

SeaTunnel Engine 集群基于 Hazelcast，是运行 SeaTunnel Engine Server 的集群成员的网络。

集群成员自动连接在一起形成集群。

这种自动加入是通过集群成员用来查找彼此的各种发现机制来实现的。

请注意，集群形成后，集群成员之间的通信始终通过 TCP/IP 进行，无论使用何种发现机制。

SeaTunnel 引擎使用以下发现机制。

TCP

您可以将 SeaTunnel Engine 配置为完整的 TCP/IP 集群。

有关配置详细信息，请参阅通过 TCP 发现成员部分。

hazelcast.yaml 配置示例如下：

  [yaml]
1
2

10
11
12
13
hazelcast:
  cluster-name: seatunnel
  network:
    join:
      tcp-ip:
        enabled: true
        member-list:
          - hostname1
    port:
      auto-increment: false
      port: 5801
  properties:
    hazelcast.logging.type: log4j2

在独立 SeaTunnel 引擎集群中我们建议使用TCP方式。

另一方面，Hazelcast 提供了一些其他的服务发现方法。详情请参考hazelcast网

3.1.4.3 Map配置

type imap持久化类型，目前仅支持hdfs。

namespace 命令空间用于区分不同业务的数据存储位置，例如OSS的桶名。

clusterName 这个参数主要用于集群隔离，我们可以通过这个来区分不同的集群，比如cluster1、cluster2，这个也可以用来区分不同的业务

fs.defaultFS We used hdfs api read/write file, so used this storage need provide hdfs configuration

if you used HDFS, you can config like this:

  [yaml]
1
2
3
4
5
6
7
8
9
10
11
12
map:
    engine*:
       map-store:
         enabled: true
         initial-mode: EAGER
         factory-class-name: org.apache.seatunnel.engine.server.persistence.FileMapStoreFactory
         properties:
           type: hdfs
           namespace: /tmp/seatunnel/imap
           clusterName: seatunnel-cluster
           storage.type: hdfs
           fs.defaultFS: hdfs://localhost:9000

我也看到最简单的配置：

  [yaml]
1
2
3
4
5
6
7
8
  map:
    map-name-template:
      map-store:
        enabled: true
        initial-mode: EAGER
        class-name: org.apache.seatunnel.engine.server.persistence.FileMapStore
        properties:
          path: /tmp/file-store-map

如果没有 HDFS 并且您的集群只有一个节点，您可以配置为使用本地文件，如下所示：

  [yaml]
1
2
3
4
5
6
7
8
9
10
11
12
map:
    engine*:
       map-store:
         enabled: true
         initial-mode: EAGER
         factory-class-name: org.apache.seatunnel.engine.server.persistence.FileMapStoreFactory
         properties:
           type: hdfs
           namespace: /tmp/seatunnel/imap
           clusterName: seatunnel-cluster
           storage.type: hdfs
           fs.defaultFS: file:///

如果你使用OSS，你可以这样配置：

  [yaml]
1
2
3
4
5

10
11

map:
    engine*:
       map-store:
         enabled: true
         initial-mode: EAGER
         factory-class-name: org.apache.seatunnel.engine.server.persistence.FileMapStoreFactory
         properties:
           type: hdfs
           namespace: /tmp/seatunnel/imap
           clusterName: seatunnel-cluster
           storage.type: oss
           block.size: block size(bytes)
           oss.bucket: oss://bucket name/
           fs.oss.accessKeyId: OSS access key id
           fs.oss.accessKeySecret: OSS access key secret
           fs.oss.endpoint: OSS endpoint
           fs.oss.credentials.provider: org.apache.hadoop.fs.aliyun.oss.AliyunCredentialsProvider

3.1.5.SeaTunnel Engine Client配置

SeaTunnel Engine Client配置是在sh $SEATUNNEL_HOME/config/hazelcast-client.yaml .

3.1.5.1.集群名称配置

客户端必须与 SeaTunnel 引擎具有相同的集群名称。

否则，SeaTunnel 引擎将拒绝客户端请求。

3.1.5.2.网络配置

cluster-members

所有 SeaTunnel 引擎服务器节点地址都需要添加到此处。

  [yaml]
1
2
3
4
5
6
7
hazelcast-client:
  cluster-name: seatunnel
  properties:
      hazelcast.logging.type: log4j2
  network:
    cluster-members:
      - hostname1:5801

3.1.6.启动Seatunnel引擎服务端节点

  [sh]
1
2
3
4
5
mkdir -p $SEATUNNEL_HOME/logs

cd $SEATUNNEL_HOME

./bin/seatunnel-cluster.sh -d

如果集群存在多台节点，需要启动所有节点上的Seatunnel引擎服务。

3.1.7.安装Seatunnel引擎客户端并启动
