0、帮助

root@adela-vm:/opt/mongodb_simple# ./bin/mongo --help
MongoDB shell version: 2.6.9
usage: ./bin/mongo [options] [db address] [file names (ending in .js)]

1、启动mongoDB 客户端进程

root@adela-vm:/opt/mongodb_simple# ./bin/mongo 127.0.0.1:12345/test
MongoDB shell version: 2.6.9
connecting to: 127.0.0.1:12345/test

2、关闭mongoDB 客户端进程
方法1：
>db.shutdownServer()
> db.shutdownServer()
shutdown command only works with the admin database; try 'use admin'
必须要admin才能使用shutdown命令

> use admin
switched to db admin
> db.shutdownServer()
2015-03-27T11:33:49.502+0800 DBClientCursor::init call() failed
server should be down...
2015-03-27T11:33:49.506+0800 trying reconnect to 127.0.0.1:12345 (127.0.0.1) failed
2015-03-27T11:33:49.506+0800 warning: Failed to connect to 127.0.0.1:12345, reason: errno:111 Connection refused
2015-03-27T11:33:49.506+0800 reconnect 127.0.0.1:12345 (127.0.0.1) failed failed couldn't connect to server 127.0.0.1:12345 (127.0.0.1), connection attempt failed
>
方法2：kill -15 进程号或者kill （不加参数）进程号
除非在特殊情况下，避免使用kill -9 进程号

3、重新启动mongo
numactl --interleave=all bin/mongod -f conf/mongod.conf
The program 'numactl' is currently not installed. You can install it by typing:
apt-get install numactl

安装numactl
apt-get install numactl
root@adela-vm:/opt/mongodb_simple/log# apt-get install numactl

4、查看日志
tail mongod.log
