# Provides:          mongodb
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: Mongodb startup script
# Description:       Mongodb start stop daemon sends SIGINT to terminate
#                    say man signal to see details

# Please check the startup params and replication options
#Mongo db usage:
#  run                      run db
#  msg [msg] [port]         send a request to the db server listening on port (or default)
#  msglots                  send many test messages, and then wait for answer on the last one
#  longmsg                  send a long test message to the db server
#  quicktest                just check basic assertions and exit
#  test2                    run test2() - see code
#
#Options:
# --help                    show this usage information
# --port <portno>           specify port number, default is 27017
# --dbpath <root>           directory for datafiles, default is /data/db/
# --quiet                   quieter output
# --cpu                     show cpu+iowait utilization periodically
# --noauth                  run without security
# --auth                    run with security
# --verbose
# -v+                       increase verbose level -v = --verbose
# --objcheck                inspect client data for validity on receipt
# --quota                   enable db quota management
# --appsrvpath <path>       root directory for the babble app server
# --nocursors               diagnostic/debugging option
# --nohints                 ignore query hints
# --nohttpinterface         disable http interface
# --nojni
# --oplog<n>                0=off 1=W 2=R 3=both 7=W+some reads
# --oplogSize <size_in_MB>  custom size if creating new replication operation log
# --sysinfo                 print some diagnostic system information
#
#Replication:
# --master
# --slave
# --source <server:port>    when a slave, specifies master
# --only <dbname>           when a slave, only replicate db <dbname>
# --pairwith <server:port> <arbiter>
# --autoresync
