时间：2023-01-26 11:28:24
<pre name="code" class="python">1、下载MongoDB（64位）

http://fastdl.mongodb.org/linux/mongodb-linux-x86_64-2.4.9.tgz

或

http://pan.baidu.com/s/1mgyRB8c

2、安装MongoDB（安装到/usr/local）

复制代码

tar zxvf mongodb-linux-x86_64-2.4.9.tgz

mv mongodb-linux-x86_64-2.4.9 mongodb

cd mongodb

mkdir db

mkdir logs

cd bin

vi mongodb.conf

复制代码

dbpath=/data01/mongodb/db

logpath=/data01/mongodb/logs/mongodb.log

port=27017

fork=true

nohttpinterface=true

3.启动monggodb 设置密码:

[root@wx03 bin]# /usr/local/mongodb/bin/mongod --config /usr/local/mongodb/bin/mongodb.conf

about to fork child process, waiting until server is ready for connections.

forked process: 2569

all output going to: /data01/mongodb/logs/mongodb.log

child process started successfully, parent exiting

[root@wx03 ~]# mongofiles list  -db pics

connected to: 127.0.0.1

4.创建用户:

[root@wx03 ~]# mongo

MongoDB shell version: 2.4.9

connecting to: test

Welcome to the MongoDB shell.

For interactive help, type "help".

>  db.addUser('pics','1234567');

{

	"user" : "pics",

	"readOnly" : false,

	"pwd" : "ef0dc53a2cae7b91e97e17759a4a9fb6",

	"_id" : ObjectId("57a93f5aad9b35eacaaa901e")

}

启动认证:

启用的时候需要加--auth   

/usr/local/mongodb/bin/mongod --config /usr/local/mongodb/bin/mongodb.conf --auth  

[root@wx03 ~]#  /usr/local/mongodb/bin/mongod --config /usr/local/mongodb/bin/mongodb.conf --auth

about to fork child process, waiting until server is ready for connections.

forked process: 2820

all output going to: /data01/mongodb/logs/mongodb.log

log file [/data01/mongodb/logs/mongodb.log] exists; copied to temporary file [/data01/mongodb/logs/mongodb.log.2016-08-09T02-40-55]

child process started successfully, parent exiting

[root@wx03 ~]# mongo

mongo         mongod        mongodump     mongoexport   mongofiles    mongoimport   mongooplog    mongoperf     mongorestore  mongos        mongosniff    mongostat     mongotop

[root@wx03 ~]# mongo

MongoDB shell version: 2.4.9

connecting to: test

> show databases;

admin	(empty)

local	0.078125GB

pics	0.203125GB

> use pics;

switched to db pics

> show databases;

admin	(empty)

local	0.078125GB

pics	0.203125GB

可以看到 单独的设置pics数据库的用户名,密码还不够,需要设置admin数据库的

线上导出数据:

[root@hy-mrz01 ~]# mongodump -d pics -o /tmp/

connected to: 127.0.0.1

Tue Aug  9 10:31:54.308 DATABASE: pics	 to 	/tmp/pics

assertion: 13106 nextSafe(): { $err: "not authorized for query on pics.system.indexes", code: 16550 }

备份数据库:

[root@hy-mrz01 ~]# mongodump  -u "pics" -p "xxx" -d pics -o /tmp/

connected to: 127.0.0.1

Tue Aug  9 10:32:26.817 DATABASE: pics	 to 	/tmp/pics

Tue Aug  9 10:32:26.817 	pics.system.indexes to /tmp/pics/system.indexes.bson

Tue Aug  9 10:32:26.817 		 7 objects

Tue Aug  9 10:32:26.817 	pics.system.users to /tmp/pics/system.users.bson

Tue Aug  9 10:32:26.818 		 1 objects

Tue Aug  9 10:32:28.069 	Metadata for pics.fs.chunks to /tmp/pics/fs.chunks.metadata.json

导入数据库:

[root@wx03 tmp]# mongorestore -u pics -p '1234567' -d pics /tmp/pics/

查看图片:

[root@wx03 tmp]# mongofiles list -u pics -p '1234567' -db pics
