#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 #参考Real world MongoDB benchmarks with benchRun https://blog.serverdensity.com/real-world-mongodb-benchmarks-with-benchrun/ 运行mongo #mongo 4、主从配置 #两个服务器修改hosts: #主上添加配置:vim /etc/mongod.conf #从上添加配置: #vim /etc/mongod.conf #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 5、监控管理{

fileSizeMB:1,
sleepMicros:0,
mmf:'true',

#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.
