1. Start via command line
mongod --port 10000 --fork --logpath /usr/local/mongodb/log/mongodb.log --logappend --dbpath =/data/db
Or configuration file startup will report an error
about to fork child process, waiting until server is ready for connections.
forked process: 1399
ERROR: child process failed, exited with error number 1
Lock files under 2.db have also been deleted and still report errors.
3. Xiao Bai sincerely asks for advice
Master/slave replication and replica set replication are two different mechanisms. The former is no longer recommended for further use. Because you set up here again
shardsvr=true, is in a shard set, so you should use replica set. The
master=trueTry deleting it.
auth=trueIn this mode, mutual authentication between clusters depends onkeyfile, please add or temporarily disable auth according to the document (note if it is a production environment or it is strongly recommended to turn on auth).
