注：安装SeaTunnel Web1.0.1没区别，步骤全部都一样。
安装的SeaTunnel为2.3.7版本，以下安装基于SeaTunnel已经安装好的场景。
一、下载包
Apache SeaTunnel
上传到服务器上并解压
-- 路径：/data/seatunnel/apache-seatunnel-web-1.0.0-bin.tar.gz
tar -zxvf apache-seatunnel-web-1.0.0-bin.tar.gz
-- 修改名字
mv apache-seatunnel-web-1.0.0-bin seatunnel-web-1.0.0二、配置数据库
1、创建seatunnel-web所需表
数据库和seatunnel-web应用没在同一台机器上
mysql上执行sql脚本，sql脚本路径为：/data/seatunnel/seatunnel-web-1.0.0/script/seatunnel_server_mysql.sql
2、配置数据库连接
vim /data/seatunnel/seatunnel-web-1.0.0/conf/application.yml
三、配置所需seatunnel配置
1、将/seatunnel/config/hazelcast-client.yaml复制到seatunnel web目录下
cp /data/seatunnel/seatunnel-2.3.7/config/hazelcast-client.yaml /data/seatunnel/seatunnel-web-1.0.0/conf修改 hazelcast-client.network.cluster-members配置
2、配置支持的插件信息
将seatunnel中的plugin-mapping.properties复制到seatunnel web目录下
cp /data/seatunnel/seatunnel-2.3.7/connectors/plugin-mapping.properties /data/seatunnel/seatunnel-web-1.0.0/conf3、如果是seatunnel web1.0.1增加secretKey，否则报错；修改文件为：/data/seatunnel/seatunnel-web-1.0.1/conf/application.yml

1、下载包
jar包下载可以使用：https://seatunnel.apache.org/assets/files/download_datasource-4b79e6fafe80459590a6a0fc2865e5ac.sh
包：mysql-connector-java-8.0.20.jar需要单独下载，下载地址：https://mvnrepository.com/artifact/mysql/mysql-connector-java/8.0.20
2、上传jar包
上传到：/data/seatunnel/seatunnel-web-1.0.0/libs路径下
五、启动程序
注意：必须到bin前面一级启动，要不然启动会报错：必须是./bin/seatunnel-backend-daemon.sh start，不能是.seatunnel-backend-daemon.sh start
# 进入/data/seatunnel/seatunnel-web-1.0.0/bin
cd /data/seatunnel/seatunnel-web-1.0.0/bin
# 给seatunnel-backend-daemon.sh加执行权限
chmod +x seatunnel-backend-daemon.sh
启动webui,注意：必须到bin前面一级启动，要不然启动会报错
cd /data/seatunnel/seatunnel-web-1.0.0
./bin/seatunnel-backend-daemon.sh start
启动成功后访问一下地址：http://机器ip:8801/ui/#/login 账号密码都是admin
六、启动后错误信息查看
启动后日志查看：/data/seatunnel/seatunnel-web-1.0.0/logs/seatunnel-web.log
问题一、NoClassDefFoundError: org/apache/seatunnel/api/sink/SinkCommonOptions
启动报以下错误，解决办法：
seatunnel-api-2.3.3.jar包缺少该类，从https://mvnrepository.com/artifact/org.apache.seatunnel/seatunnel-api/2.3.7 下载jar包（jar包版本跟seatunnel版本匹配，当前安装的seatunnel是2.3.7版本，所以下载的2.3.7版本的包）

问题2：找到数据源
寻找原因中……原本安装的seatunnel web1.0.1有下面这个问题，降了一个版本到1.0.0结果发现还是有这个问题。
