yum install -y mongo-10gen mongo-10gen-server

#添加到開機自動啟動

chkconfig mongod on

2、啟動，停止，重啟命令

service mongod start
service mongod stop
service mongod restart

3、測試

#mongoperf -h

usage:
 mongoperf < myjsonconfigfile
{
  nThreads:<n>,   // number of threads (default 1)
  fileSizeMB:<n>,  // test file size (default 1MB)
  sleepMicros:<n>, // pause for sleepMicros/nThreads between each operation (default 0)
  mmf:<bool>,    // if true do i/o's via memory mapped files (default false)
  r:<bool>,     // do reads (default false)
  w:<bool>,     // do writes (default false)
  recSizeKB:<n>,  // size of each write (default 4KB)
  syncDelay:<n>   // secs between fsyncs, like --syncdelay in mongod. (default 0/never)
}

進行測試：

[root@php1 ~]# cat <jsonfile

{
  nThreads:1,
  fileSizeMB:1,
  sleepMicros:0,
  mmf:'true',
  r:'true',
  w:'true',
  recSizeKB:4,
  syncDelay:0
 }

5、監控管理

#mongostat

The mongostat utility provides a quick overview of the status of a currently running mongod or mongos instance. mongostat is functionally similar to the UNIX/Linux file system utility vmstat, but provides data regarding mongod and mongos instances.

#mongotop

mongotop provides a method to track the amount of time a MongoDB instance spends reading and writing data. mongotop provides statistics on a per-collection level. By default, mongotop returns values every second.
