问题分析
查看部署路径/apps/tidb/test_cluster/deploy/pd-2385已经包含,pd无法启动起来。排查问题发现/apps/tidb/test_cluster/deploy/pd-2385/scripts中的run_pd.sh脚本有问题
问题解决
1)将该name改为pd-172.21.141.61-2385,执行脚本/apps/tidb/test_cluster/deploy/pd-2385/scripts/run_pd.sh 即可成功启动。
2)tiup cluster edit-config test_cluster 手工添加pd-2385的配置信息
- host: 172.21.141.61ssh_port: 22name: pd-172.21.141.61-2385client_port: 2385peer_port: 2386deploy_dir: /apps/tidb/test_cluster/deploy/pd-2385data_dir: i/apps/tidb/test_cluster/data/pd-2385
3) reload cluster
后续
在单机扩展tidb和tikv的时候没有遇到该问题。
考虑是脚本在生成pd name的时候出现问题。
在scale-out脚本中手工指定pd-name同样会报错,run_pd.sh中的name怀疑是按照pd同步数据端口来自动生成,会造成名称重复,应该是tiup本身bug。
