1. 环境准备

环境名称	版本
系统环境	CentOS7.9
Java环境	JDK1.8

1.1 系统环境

略

1.2 Java环境安装

下载jdk1.8安装包并拷贝到服务器

# 进入文件夹
cd /usr/local
#  将jdk拷贝到该位置
#  解压文件
tar -zxvf jdk-8u381-linux-x64.tar.gz

修改环境变量

vim /etc/profile

在环境变量中添加Java环境

export JAVA_HOME=/usr/local/jdk1.8.0_381/
export CLASSPATH=$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PATH:$JAVA_HOME/bin

重新加载环境变量

source /etc/profile

验证Java环境

java -version

1.3 SeaTunnel单节点安装

下载安装包

下载地址：

Apache SeaTunnel

下载SeaTunnel安装包

下载SeaTunnel Web安装包

创建安装SeaTunnel 目录

# 创建用于安装SeaTunnel 后台引擎的目录
mkdir -p /opt/seatunnel/backend
# 创建用户安装SeaTunnel Web前台页面的目录
mkdir -p /opt/seatunnel/web

拷贝并安装SeaTunnel

# 进入到SeaTunnel 后台安装目录，将下载好的安装包拷贝到该目录
[root@localhost backend]# pwd
/opt/seatunnel/backend
[root@localhost backend]# ls
apache-seatunnel-2.3.3-bin.tar.gz
# 安装SeaTunnel 后台
tar -zxvf apache-seatunnel-2.3.3-bin.tar.gz# 进入到SeaTunnel Web页面程序安装目录，将下载号的安装包拷贝到该目录
[root@localhost web]# pwd
/opt/seatunnel/web
[root@localhost web]# ls
apache-seatunnel-web-1.0.0-bin.tar.gz
# 安装SeaTunnel Web页面程序
tar -zxvf apache-seatunnel-web-1.0.0-bin.tar.gz

将SeaTunnel 后台配置到环境变量中

# 打开环境变量文件
vim /etc/profile# 在环境变量文件最后添加如下配置
export SEATUNNEL_HOME=/opt/seatunnel/backend/apache-seatunnel-2.3.3
export PATH=$PATH:$SEATUNNEL_HOME/bin# 重新加载环境变量文件
source /etc/profile

安装需要的连接器

# 进入到seatunnel 安装目录下
[root@localhost seatunnel]# cd apache-seatunnel-2.3.3
# 进入到插件配置文件中          
[root@localhost apache-seatunnel-2.3.3]# vim config/plugin_config
# 删除多余连接器，留下需要用到的连接器
--connectors-v2--
connector-cdc-mysql
connector-cdc-sqlserver
connector-doris
connector-elasticsearch
connector-jdbc
--end--
# 退出保存连接器配置文件
:qw
# 在线安装拦截器
[root@localhost apache-seatunnel-2.3.3]# sh bin/install-plugin.sh 
# 等待安装，安装完成后可查看已经安装的连接器
[root@localhost apache-seatunnel-2.3.3]# ls connectors/seatunnel/*
connectors/seatunnel/connector-cdc-mysql-2.3.3.jar
connectors/seatunnel/connector-cdc-sqlserver-2.3.3.jar
connectors/seatunnel/connector-console-2.3.3.jar
connectors/seatunnel/connector-doris-2.3.3.jar
connectors/seatunnel/connector-elasticsearch-2.3.3.jar
connectors/seatunnel/connector-fake-2.3.3.jar
connectors/seatunnel/connector-jdbc-2.3.3.jar

注意：

connector-jdbc 连接器可以连接多种使用JDBC进行连接的多种数据库，如下：

MySQL、PostgreSQL、DM、Phoenix 、SQLServer、Oracle、sqlite、GBase8a、StarRocks、db2、saphana、Doris、teradata、Redshift、Snowflake、Vertica、OceanBase

拷贝需要的数据库连接jar包

# 进入SeaTunnel 后台安装目录
cd /opt/seatunnel/backend/apache-seatunnel-2.3.3
# 创建连接器对应的目录，用于存放数据库连接驱动
[root@localhost apache-seatunnel-2.3.3]# mkdir -p plugins/jdbc/lib/
# 将下载的数据库连接包上传到该目录下
[root@localhost lib]# pwd
/opt/seatunnel/backend/apache-seatunnel-2.3.3/plugins/jdbc/lib
[root@localhost lib]# ls
mysql-connector-java-8.0.28.jar  ojdbc8.jar  postgresql-42.6.0.jar

数据库连接包下载地址：

数据库	下载地址
mysql	https://mvnrepository.com/artifact/mysql/mysql-connector-java
oracle	https://mvnrepository.com/artifact/com.oracle.database.jdbc/ojdbc8
postgresql	https://mvnrepository.com/artifact/org.postgresql/postgresql
doris	https://mvnrepository.com/artifact/mysql/mysql-connector-java

测试验证

# 进入SeaTunnel 后台安装目录
cd /opt/seatunnel/backend/apache-seatunnel-2.3.3
# 跑样例脚本
sh bin/seatunnel.sh --config config/v2.batch.config.template -e local

出现以下信息表示验证成功

后台启用服务

# 进入SeaTunnel 后台安装目录
cd /opt/seatunnel/backend/apache-seatunnel-2.3.3
# 启动服务
nohup sh bin/seatunnel-cluster.sh 2>&1 &

查看SeaTunnel 运行日志

# 查看SeaTunnel运行日志
tail -100f logs/seatunnel-engine-server.log

日志中有以下信息表示后台启动成功

1.4 安装SeaTunnel Web

注意：必须保证SeaTunnel的后台引擎服务正常运行，Web端才可以正常运行。

安装MySQL客户端

因为SeaTunnel Web 需要连接到MySQL数据库，并初始化数据库，所以需要安装MySQL Client。

# 先检查服务器中是否存在mariadb
rpm -qa|grep mariadb
#删除相关依赖包（若不存在，可以跳过）
rpm -e --nodeps mariadb-libs
#检查是否删除干净
rpm -qa|grep mariadb
# 检查MySQL
rpm -qa|grep mysql# 创建一个目录用于存放MySQL Client 安装文件
mkdir -p /opt/mysqlrpm
# 将安装包拷贝到该目录下
[root@localhost mysqlrpm]# pwd
/opt/mysqlrpm
[root@localhost mysqlrpm]# ls
lrzsz-0.12.20-36.el7.x86_64.rpm
mysql-community-client-5.7.40-1.el7.x86_64.rpm
mysql-community-common-5.7.40-1.el7.x86_64.rpm
mysql-community-libs-5.7.40-1.el7.x86_64.rpm
# 安装lrzsz 
rpm -ivh lrzsz-0.12.20-36.el7.x86_64.rpm
# 按照顺序安装MySQL Client 
rpm -ivh mysql-community-common-5.7.40-1.el7.x86_64.rpm 
rpm -ivh mysql-community-libs-5.7.40-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-5.7.40-1.el7.x86_64.rpm

修改SeaTunnel Web 下script/seatunnel_server_env.sh中连接数据库信息

# 进入到SeaTunnel Web 安装目录
cd /opt/seatunnel/web/apache-seatunnel-web-1.0.0-bin
# 备份script/seatunnel_server_env.sh文件
cp script/seatunnel_server_env.sh script/seatunnel_server_env.sh.bak
# 修改script/seatunnel_server_env.sh文件
vim script/seatunnel_server_env.sh
# 修改以下配置信息
export HOSTNAME="127.0.0.1"
export PORT="3306"
export USERNAME="root"
export PASSWORD="123456"
# 修改如下,加上了前缀，以防与系统中其它配置冲突
# 将数据库连接信息修改成你要链接的信息
export STWEB_HOSTNAME="127.0.0.1"
export STWEB_PORT="3306"
export STWEB_USERNAME="root"
export STWEB_PASSWORD="123456"

修改SeaTunnel Web 下script/init_sql.sh 中连接数据库信息

vim script/init_sql.sh

主要是保证里边的${XXXXX}的配置信息与script/seatunnel_server_env.sh中的保持一致。

执行数据库初始化脚本

# 进入SeaTunnel Web 安装目录
cd /opt/seatunnel/web/apache-seatunnel-web-1.0.0-bin
# 执行初始化文件
sh script/init_sql.sh

修改SeaTunnel Web 连接MySQL数据库的配置信息

# 进入SeaTunnel Web 安装目录
cd /opt/seatunnel/web/apache-seatunnel-web-1.0.0-bin
# 打开SeaTunnel Web 配置文件
vim conf/application.yml
# 修改以下部分配置：端口号，MySQL连接IP，MySQL用户名和密码
server:#port: 8801port: 8882spring:application:name: seatunneljackson:date-format: yyyy-MM-dd HH:mm:ssdatasource:driver-class-name: com.mysql.jdbc.Driverurl: jdbc:mysql://192.168.1.111:3306/seatunnel?useSSL=false&useUnicode=true&characterEnc
oding=utf-8&allowMultiQueries=true&allowPublicKeyRetrieval=true    username: rootpassword: 123456

配置client信息

# 将seatunnel后台的两个文件拷贝到web的conf目录下
cp /opt/seatunnel/backend/apache-seatunnel-2.3.3/config/hazelcast-client.yaml conf/
cp /opt/seatunnel/backend/apache-seatunnel-2.3.3/connectors/plugin-mapping.properties conf/

下载Web程序需要的数据源（数据源需要的各种jar包）

这里在各种jar包，如果缺失的话，在Web页面创建数据源时会出现空数据源的情况。

下载jar包

首先你自己的电脑上安装了github

下载jar包额度脚本

我是在我电脑的D盘根目录下，创建了download_datasource.sh文件，文件内容如下：

有两处需要修改，请看注释。

##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 web home
# SEATUNNEL_WEB_HOME=$(cd $(dirname $0);cd ../;pwd)
# 此处需要修改成你本地的目录
DATASOURCE_DIR=D:/down_jars# If you don’t want to download a certain data source, you can delete the element below
datasource_list=("datasource-plugins-api""datasource-elasticsearch""datasource-hive""datasource-jdbc-clickhouse""datasource-jdbc-hive""datasource-jdbc-mysql""datasource-jdbc-oracle""datasource-jdbc-postgresql""datasource-jdbc-redshift""datasource-jdbc-sqlserver""datasource-jdbc-starrocks""datasource-jdbc-tidb""datasource-kafka""datasource-mysql-cdc""datasource-s3""datasource-sqlserver-cdc""datasource-starrocks"
)# the datasource default version is 1.0.0, you can also choose a custom version. eg: 1.1.2:  sh install-datasource.sh 2.1.2
version=1.0.0if [ -n "$1" ]; thenversion="$1"
fiecho "Downloading SeaTunnel Web Datasource lib, usage version is ${version}"# create the datasource directory
if [ ! -d "$DATASOURCE_DIR" ];thenmkdir -p "$DATASOURCE_DIR"echo "Created datasource directory."
fifor i in "${datasource_list[@]}"
doecho "$i"echo "Downloading datasource: " "$i"
# 修改成mvnmvn dependency:get -DgroupId=org.apache.seatunnel -DartifactId="$i" -Dversion="$version" -Ddest="$DATASOURCE_DIR"
done

之后在download_datasource.sh目录下点击鼠标右键，选择Git Bash Here

之后在打开的页面执行 sh download_datasource.sh 点击回车，等待下载完成。

之后将下载下来的包，拷贝到SeaTunnel Web 程序的 /libs目录下。

将MySQL Jar 包拷贝到libs目录下

将mysql连接数据库的Jar 拷贝到 /libs 目录下，否则Web程序启动时会报错，连不上数据库。

启动SeaTunnel Web 程序

# 进入SeaTunnel Web 安装目录
cd /opt/seatunnel/web/apache-seatunnel-web-1.0.0-bin
# 启动SeaTunnel Web
sh bin/seatunnel-backend-daemon.sh start
# 查看启动日志
tail -100f logs/seatunnel-web.log

配置开放端口号(两种方式)

#-------------iptables-----------------
#开打端口号开放配置文件
vim /etc/sysconfig/iptables
# 添加一行
-A INPUT -p tcp -m state --state NEW -m tcp --dport 8882 -j ACCEPT
# 重启启动防火墙
systemctl restart iptables.service
#------------firewall-------------------
# 依次执行下面命令
firewall-cmd --zone=public --add-port=8882/tcp --permanent
firewall-cmd --reload
firewall-cmd --list-all
