ticdc部署yaml文件

      Cluster name: tidb-acloud
      Cluster version: v8.1.1
      Role Host Ports OS/Arch Directories

cdc 10.201.14.2 8300 linux/x86_64 /app/tidbsoft/cdc-8300,/app/tidbdata/cdc-8300
cdc 10.201.14.3 8300 linux/x86_64 /app/tidbsoft/cdc-8300,/app/tidbdata/cdc-8300
Attention:
1. If the topology is not what you expected, check your yaml file.
2. Please confirm there is no port/directory conflicts in same host.

CDC不应该是在toolkit下面吗，为啥这个在server下面

3

tiup mirror show 看下cdc包在不在

tar xf tidb-community-toolkit-${version}-linux-amd64.tar.gz
ls -ld tidb-community-server-${version}-linux-amd64 tidb-community-toolkit-${version}-linux-amd64
cd tidb-community-server-${version}-linux-amd64/
cp -rp keys ~/.tiup/
tiup mirror merge …/tidb-community-toolkit-${version}-linux-amd64
这些做了吗？

正常流程应该是下一个toolkit包，然后cp key + merge 之后会拉取那个包，但是你这个在server下 ，感觉拉取不到

:yum:是不是搞得离线镜像，结果离线镜像里没有？

6

在线搞的啊，试试把包拉下来，离线部署试试

7

我把这个包拷贝到server下了

8

大佬们，原来拷贝cdc包到tidb-community-server-v8.1.1-linux-amd64目录不行，硬是要merge mirror，已经安装成功了

照着官方文档离线安装复制粘贴一遍，每个包都要单独加的
