使用tftp烧写开发板，基于centos 6.4mdash;mdash;tq2440
1、安装
--------------------------------------------------------------------------------
#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
{
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... res = benchrun( { parallel : x ,
... seconds : 5 ,
... ops : ops
... } )
... print(threads: + x +\t queries/sec: + res.query )
... }
