企业官网建设流程全解析

1：配置好Java8，seatunnel的环境变量（自行配置，网上一大堆配置方法）

2：关键的步骤来了，一定要调成动态端口，不然总是报错端口被占用

seatunnel.yaml seatunnel: engine: classloader-cache-mode: true history-job-expire-minutes: 1440 backup-count: 1 queue-type: blockingqueue print-execution-info-interval: 60 print-job-metrics-info-interval: 60 slot-service: dynamic-slot: false checkpoint: interval: 10000 timeout: 60000 storage: type: hdfs max-retained: 3 plugin-config: namespace: /data/seatunnel/imap storage.type: hdfs fs.defaultFS: file:/// telemetry: metric: enabled: false logs: scheduled-deletion-enable: true http: enable-http: true port: 8090 enable-dynamic-port: true #这里一定要是动态端口，通过观察日志，启动作业的时候，作业会抢占这个端口，导致总是报错端口被占用 hazelcast.yaml hazelcast: cluster-name: seatunnel-dev network: rest-api: enabled: false endpoint-groups: CLUSTER_WRITE: enabled: true DATA: enabled: true join: tcp-ip: enabled: true member-list: - bigdata-node4 port: auto-increment: true #这里一定要是动态端口，通过观察日志，启动作业的时候，作业会抢占这个端口，导致总是报错端口被占用 port: 5801 properties: hazelcast.invocation.max.retry.count: 20 hazelcast.tcp.join.port.try.count: 30 hazelcast.logging.type: log4j2 hazelcast.operation.generic.thread.count: 50 hazelcast.heartbeat.failuredetector.type: phi-accrual hazelcast.heartbeat.interval.seconds: 2 hazelcast.max.no.heartbeat.seconds: 180 hazelcast.heartbeat.phiaccrual.failuredetector.threshold: 10 hazelcast.heartbeat.phiaccrual.failuredetector.sample.size: 200 hazelcast.heartbeat.phiaccrual.failuredetector.min.std.dev.millis: 100 hazelcast-client.yaml hazelcast-client: cluster-name: seatunnel-dev properties: hazelcast.logging.type: log4j2 connection-strategy: connection-retry: cluster-connect-timeout-millis: 3000 network: cluster-members: - bigdata-node4:5801

不改动态端口就报错

总结：官网也是真垃圾，这些问题是只字不提啊，甚至脚本的路径的目录在程序中已经被弃用了，文档也不更新，就那个插件存放jar包的路径

这官网文档让执行的脚本

根本没有那个目录了，程序里一点没有涉及。恶心啊
