Is it an offline installation? Have you downloaded the tools package?

Higher version pump and drainer are in another image. For local deployment, you need to merge the images first: 使用 TiUP 部署 TiDB 集群 | PingCAP 文档中心

This version also does not recommend using binlog.

A good feature has been deprecated.

There have been quite a few changes since we started using TiCDC.

Don’t use it anymore, TiDB will deprecate Pump in the future.

| username: 像风一样的男子 | Original post link

CDC is not as easy to use as binlog and has higher fault tolerance.

However, binlog is ultimately a feature of MySQL. If TiDB wants to implement its own new features, it will have to abandon this.

Why can’t I download the image merge?

Offline deployment is fine, and it’s very simple Using TiUP to Deploy a TiDB Cluster | PingCAP Documentation Center

Binlog is not MySQL. TiDB just calls it that… Actually, it has nothing to do with MySQL binlog.

| username: zhanggame1 | Original post link

My response here is indeed problematic; the two are not related. However, TiDB is also about to deprecate binlog.

| username: oceanzhang | Original post link

Actually, I tested this tool and it works fine.

| username: WalterWj | Original post link

Indeed, let’s leave it at that.

Re-download the image package, installation and startup of TiDB failed.

Is port 4000 occupied?

| username: TiDBer_OB4kHrS7 | Original post link

No, it’s a brand new machine, and there are no other services running on it.
