BUILDING
See docs/building.md.
RUNNING
For command line options invoke:
$ ./mongod --help
To run a single server database:
$ sudo mkdir -p /data/db
$ ./mongod
$
$ # The mongo javascript shell connects to localhost and test database by default:
$ ./mongo
> help

我们现在用配置文件的形式来开启服务
port=27017
bind_ip=0.0.0.0
dbpath=/package/mongo/data ### 提前创建好目录
logpath=/package/mongo/logs/logs.log ### 提前创建好文件
fork=true
5.开启服务
[root@centosa bin]# ./mongod -f mdb.conf
about to fork child process, waiting until server is ready for connections.
forked process: 18988
child process started successfully, parent exiting
6.测试连接
连接成功
[root@centosa bin]# ./mongo

Enable MongoDB's free cloud-based monitoring service, which will then receive and display
metrics about your deployment (disk utilization, CPU, operation statistics, etc).
The monitoring data will be available on a MongoDB website with a unique URL accessible to you
and anyone you share the URL with. MongoDB may use this information to make product
improvements and to suggest MongoDB products and deployment options to you.
To enable free monitoring, run the following command: db.enableFreeMonitoring()
To permanently disable this reminder, run the following command: db.disableFreeMonitoring()
