浅酌MongoDB---服务端命令

    Hi大家好，我是小魂。关于服务端命令，直接在cmd中敲help就能得到。但是每次都打help是不是太麻烦呢？好吧，我帮你把他弄出来了。如下：

db.help()　　 help on db methods
db.mycoll.help()　 　help on colleciton methods
rs.help()　 　help on replica set methods
help admin　 　administrative help
help connect 　　connecting to a db help
help keys　 　key shortcuts
help misc　 　misc things to know
help mr　 　mapreduce

show dbs 　　show database names
show collections 　　show collections in current database
show users　　 show users in current database
show profile　　 show most recent system.profile entries with time >= 1ms
show logs　　 show the accessible logger names
show log [name] 　　prints out the last segment of log in memory, 'global' is default
use <db_name> 　　set current database
db.foo.find()　　 list objects in collection foo
db.foo.find( { a : 1 } ) 　　list objects in foo where a == 1
it 　　result of the last line evaluated; use to further iterate
DBQuery.shellBatchSize = x　　 set default number of items to display on shell
exit 　　quit the mongo shell

DB methods: 
db.addUser(username, password[, readOnly=false]) 
db.auth(username, password) 
db.cloneDatabase(fromhost) 
db.commandHelp(name)   　　 returns the help for the command 
db.copyDatabase(fromdb, todb, fromhost) 
db.createCollection(name, { size : ..., capped : ..., max : ...} ) 
db.currentOp()    　　display the current operation in the db 
db.dropDatabase() 
db.eval(func, args)    　　run code server-side 
db.getCollection(cname)    　　same as db['cname'] or db.cname 
db.getcollectionNames() 
db.getLastError()    　　- just returns the err msg string

db.getProfilingLevel()   　　 - deprecated 
db.getProfilingStatus()    　　-returns if profiling is on and slow threshold

db.runCommand(cmdObj)   　　 run a database command. if cmdObj is a string, turns it into { cmdObj : 1 } 
db.serverStatus() 
db.setProfilingLevel(level,<slowms>) 0=off 1=slow 2=all 
db.shutdownServer() 
db.stats() 
db.version()   　　 current version of the server 
db.getMongo().setSlaveOk()    　　allow queries on a replication slave server
