3.配置

#同步模式为所有同步
sync_mode = all
#源mongodb
mongo_urls = mongodb://root:rootpa***@192.168.1.28:30001,192.168.1.29:30001,192.168.1.27:30001
#源mongodb的config
mongo_cs_url = mongodb://root:rootpa***@192.168.1.28:30002,192.168.1.29:30002,192.168.1.27:30002
#源mongodb的mongos
mongo_s_url = mongodb://root:rootpa***@192.168.1.28:40001 
tunnel = direct
#目标mongodb
tunnel.address = mongodb://root:rootpa***@192.168.1.12:30001
tunnel.message = raw
mongo_connect_mode = secondaryPreferred
#要迁移的db
filter.namespace.white = test
#开启DDL同步
filter.ddl_enable = true
checkpoint.storage.url = mongodb://root:rootpa***@192.168.1.12:30001
