MongoDB installation, master-slave configuration, and monitorin

1. Installation

# add installation source

[mongodb] name=MongoDB Repositorybaseurl= http://downloads-distro.mongodb.org/repo/redhat/os/x86_64/gpgcheck=0enabled=1#yum installation

Yum install-y mongo-10gen mongo-10gen-server

# add to Boot Auto start

Chkconfig mongod on

2. Start, stop, restart command

Service mongod startservice mongod stopservice mongod restart

3. Testing

Use mongoperf to view disk IO performance

# mongoperf-h

Usage: mongoperf

< myjsonconfigfile{ nThreads:, // number of threads (default 1) fileSizeMB:, // test file size (default 1MB) sleepMicros:, // pause for sleepMicros/nThreads between each operation (default 0) mmf:, // if true do i/o's via memory mapped files (default false) r:, // do reads (default false) w:, // do writes (default false) recSizeKB:, // size of each write (default 4KB) syncDelay: // secs between fsyncs, like --syncdelay in mongod. (default 0/never)} 进行测试： [root@php1 ~]# cat db.foo.insert( { _id : 1 } )>

Ops = [{op: "findOne", ns: "test.foo", query: {_ id: 1}}, {op: "update", ns: "test.foo", query: {_ id: 1}, update: {$inc: {x: 1}] [{"op": "findOne", "ns": "test.foo", "query": {"_ id": 1}, {"op": "update", "ns": "test.foo" "query": {"_ id": 1}, "update": {"$inc": {"x": 1}}] > for (x = 1) Xuse local > db.slaves.find () / * 0 * / {"_ id": ObjectId ("526b44843f12574552e6ce48"), "config": {"host": "172.17.16.21 526b44843f12574552e6ce48", "upgradeNeeded": true}, "ns": "local.oplog.$main", "syncedTo": Timestamp (1382870579, 1)}

5. Monitoring and management

# 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.
