1、基于mongo實(shí)現(xiàn)遠(yuǎn)程連接

[plain] view plaincopy

mongo -u admin -p admin 192.168.0.197:27017/pagedb

通過(guò)mongo實(shí)現(xiàn)連接，可以非常靈活的選擇參數(shù)選項(xiàng)，參看命令幫助，如下所示：

[plain] view plaincopy

mongo --help
MongoDB shell version: 1.8.3
usage: mongo [options] [db address] [file names (ending in .js)]
db address can be:
foo foo database on local machine
192.169.0.5/foo foo database on 192.168.0.5 machine
192.169.0.5:9999/foo foo database on 192.168.0.5 machine on port 9999
options:
--shell run the shell after executing files
--nodb don't connect to mongod on startup - no 'db address'
arg expected
--quiet be less chatty
--port arg port to connect to
--host arg server to connect to
--eval arg evaluate javascript
-u [ --username ] arg username for authentication
-p [ --password ] arg password for authentication
-h [ --help ] show this usage information
--version show version information
--verbose increase verbosity
--ipv6 enable IPv6 support (disabled by default)

2、基于MongoDB支持的javascript實(shí)現(xiàn)遠(yuǎn)程連接

當(dāng)你已經(jīng)連接到一個(gè)遠(yuǎn)程的MongoDB數(shù)據(jù)庫(kù)服務(wù)器（例如，通過(guò)mongo連接到192.168.0.184），現(xiàn)在想要在這個(gè)會(huì)話中連接另一個(gè)遠(yuǎn)程的數(shù)據(jù)庫(kù)服務(wù)器（192.168.0.197），可以執(zhí)行如下命令：

[plain] view plaincopy

> var x = new Mongo('192.168.0.197:27017')
> var ydb = x.getDB('pagedb');
> use ydb
switched to db ydb
> db
ydb
> ydb.page.findOne()
{
"_id" : ObjectId("4eded6a5bf3bfa0014000003"),
"content" : "巴黎是浪漫的城市，可是...",
"pubdate" : "2006-03-19",
"title" : "巴黎：從布魯塞爾趕到巴黎",

上述通過(guò)MongoDB提供的JavaScript腳本，實(shí)現(xiàn)對(duì)另一個(gè)遠(yuǎn)程數(shù)據(jù)庫(kù)服務(wù)器進(jìn)行連接，操作指定數(shù)據(jù)庫(kù)pagedb的page集合。

如果啟用了安全認(rèn)證模式，可以在獲取數(shù)據(jù)庫(kù)連接實(shí)例時(shí)，指定認(rèn)證賬號(hào)，例如：

[plain] view plaincopy

> var x = new Mongo('192.168.0.197:27017')
> var ydb = x.getDB('pagedb', 'shirdrn', '(jkfFS$343$_\=\,.F@3');
> use ydb
switched to db ydb
