Mongodb 安装迁移

<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.

> use pics;
switched to db pics
>  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.

[root@wx03 ~]# mongo

[root@wx03 ~]# mongo

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 	pics.system.users to /tmp/pics/system.users.bson
Tue Aug  9 10:32:26.818 		 1 objects
Tue Aug  9 10:32:26.818 	Metadata for pics.system.users to /tmp/pics/system.users.metadata.json

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
