dm 使用 DM-Ansible安装之后，可以从源端的mysql拉取数据到dm的work目录下。 但是不能从work到目标端的tidb中。 使用dm-ctl查看状态的时候，报错 [tidb@localhost dm-ansible]$ dmctl -master-addr 10.8.181.146 parse cmd flags err: specify master addr 10.8.181.146: address 10.8.181.146: missing port in address [tidb@localhost dm-ansible]$
查看dm-master状态 [tidb@localhost dm-ansible]$ ps -ef|grep dm-master tidb 25496 1 0 10:51 ? 00:00:00 bin/dm-master --master-addr=:8261 -L=info --config=conf/dm-master.toml --log-file=/data/dm/log/dm-master.log
日志/data/dm/log/dm-master.log中报错
