#添加安装源
[MongoDB] name=MongoDB Repository baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/x86_64/ gpgcheck=0 enabled=1#yum 安装
yum install -y mongo-10gen mongo-10gen-server
#添加到开机自动启动
chkconfig mongod on
2、启动,停止,重启命令
service mongod start service mongod stop service mongod restart
3、测试
使用mongoperf 查看磁盘IO性能
#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
{ nThreads:1, fileSizeMB:1, sleepMicros:0, mmf:'true', r:'true', w:'true', recSizeKB:4, syncDelay:0 }
#参考Real world MongoDB benchmarks with benchRun
https://blog.serverdensity.com/real-world-mongodb-benchmarks-with-benchrun/
运行mongo
#mongo
>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; x<=128; x*=2){ ... res = benchRun( { parallel : x , ... seconds : 5 , ... ops : ops ... } ) ... print("threads: "+ x +"\t queries/sec: "+ res.query ) ... } threads: 1 queries/sec: 7886.8 threads: 2 queries/sec: 12786.2 threads: 4 queries/sec: 14891.2 threads: 8 queries/sec: 16361.2 threads: 16 queries/sec: 19811.6 threads: 32 queries/sec: 18343.8 threads: 64 queries/sec: 26470.4 threads: 128 queries/sec: 36110.4
4、主从配置
主 | php1 | 172.17.16.7 |
从 | MySQL1 | 172.17.16.21 |
#两个服务器修改hosts:
172.17.16.7 php1.domain.com
#主上添加配置:vim /etc/mongod.conf
master = true source = php1.dapingmu.conf
#从上添加配置:
#vim /etc/mongod.conf
slave = true source = php1.dapingmu.com
#查看主从,使用robomongo或直接在服务器上使用命令行工具
#主服务器上
#mongo
>use local >db.slaves.find() /* 0 */ { "_id" : ObjectId("526b44843f12574552e6ce48"), "config" : { "host" : "172.17.16.21:29025", "upgradeNeeded" : true }, "ns" : "local.oplog.$main", "syncedTo" : Timestamp(1382870579, 1) }
5、监控管理
#mongostat
Themongostat utility provides a quick overview of the status of a currently runningmongod ormongos instance.mongostat is functionally similar to the UNIX/Linux file system utilityvmstat, but provides data regardingmongod andmongos 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.
