Parameter description for mongodb profile

Parameter description of mongodb:-- dbpath database path (data file)-- logpath log file path-- master specifies the master machine-- slave specifies the IP address of the master machine-- source specifies the IP address of the master machine-- pologSize specifies that the log file size does not exceed 64m. Because resync is very heavy and time-consuming, it is best to avoid resync by setting a large enough oplogSize (the default oplog size is 5% of the free disk size). -- add at the end of the logappend log file-- port enable port number-- fork runs in the background-- only specifies which database is replicated only-- slavedelay refers to the time interval detected from replication-- whether auth requires authentication permission login (username and password)
