mongodb yum方式安装的,则可以直接用 :service mongod start/stop 来启动和停止;千万不用kill -9 PID的命令来停止,这样会损伤mongodb。

以上是mongodb yum安装后在/etc/mongod.conf 中的默认内容;
给安装好了的mongodb 添加用户和密码:
首先,启动mongodb;
在任何目录下输入:mongo;
[root@i-E79D4B11 ~]# mongo
MongoDB shell version: 2.6.6
connecting to: test
>
出现以上信息,表示连接成功:
#use admin; #使用admin数据库;
#show collections; #查看集合;
#db.system.users.find(); #查看dmin数据库中的users中的记录
#db.addUser('changhongeb','changhongeb'); #为changhongeb 数据库添加 changhongeb 用户;3.0版本的mongodb 不能再使用addUser(),而是用db.createUser({user:"chbigdata",pwd:"chbigdata",roles:["readWrite","dbAdmin","dbOwner"]}) 来添加用户。
我添加成功后提示信息如下:
WARNING: The 'addUser' shell helper is DEPRECATED. Please use 'createUser' instead
Successfully added user: { "user" : "changhongeb", "roles" : [ "root" ] }
#vim /etc/mongodb.conf //将auth=true前面的注释拿掉
#service mongod restart //或者用下边的命令
# /etc/init.d/mongod restart //重启生效
再次连接 mongo;使用changhongeb数据库;
> use changhongeb;
switched to db changhongeb
> show dbs;
2014-12-14T02:37:45.592+0800 listDatabases failed:{
"ok" : 0,
"errmsg" : "not authorized on admin to execute command { listDatabases: 1.0 }",
"code" : 13
} at src/mongo/shell/mongo.js:47
>
以上信息显示显示dbs失败,因为我们开启权限认证,则没通过认证;
> use admin //切换到admin数据库
switched to db admin
> db.auth('changhongeb','changhongeb'); //将changhongeb数据库的changhongeb用户认证
1
> use changhongeb; //切换到changhongeb数据库
switched to db changhongeb
> show dbs;
admin 0.078GB
changhongeb (empty)
imgs (empty)
local 0.078GB
>
以上则表示认证成功;
http://21jhf.iteye.com/blog/2216103 mongodb3.0版本以后的认证方式。
接上,添加普通用户;
> db.addUser('changhongeb','changhongeb'); //给changhongeb数据库添加一个可以读写的普通用户
WARNING: The 'addUser' shell helper is DEPRECATED. Please use 'createUser' instead
Successfully added user: { "user" : "changhongeb", "roles" : [ "dbOwner" ] }
