[原]编译MongoDB,C++连接MongoDB测试

1、C++ driver download

地址：http://dl.mongodb.org/dl/cxx-driver/

这里下载最新的cxx-driver/mongodb-linux-x86_64-v2.0-latest.tgz版本；

注：编译驱动之前需要安装pcre 和 scons 。并且g++版本需要4.0之后；

        并且需要boost，关于boost的安装可以参考前面一篇文章：http://blog.csdn.net/yuandianlws/article/details/7027538

2、 编译

[root@cdh3-0005 mongo-cxx-driver-v2.0]# scons

编译之后会出现libmongoclient.so

[root@cdh3-0005 mongo-cxx-driver-v2.0]# ls
authTest       clientTest       firstExample       libmongoclient.a       LICENSE.txt       SConstruct       whereExample
client       config.log       httpClientTest       libmongoclient.so       mongo       secondExample 

把 libmongoclient.so 拷贝至 /usr/local/lib下

[root@cdh3-0005 mongo-cxx-driver-v2.0]#cp libmongoclient.so /usr/local/lib

另外，由于目前mongo-cxx-driver没有32位的driver包，所以你可以编译MongoDB的源代码进行安装，里面包括了C++的driver

不过它需要下载依赖包  
ftp://ftp.mozilla.org/pub/mozilla.org/js
cd src
make
make install
编译mongoDB并install
tar -xvf mongodb-src-r2.0.4.tar.gz
cd mongodb-src-r2.0.4 
scons --full install

3、测试

#include <iostream>
#include "mongo/client/dbclient.h"
using namespace std;
using namespace mongo;

void run() {
DBClientConnection c;
c.connect("localhost"); //add port,c.connect("localhost:27017")
}

int main(void)
{
try {
run();
cout<<"connected ok"<<endl;
}catch(DBException& e){
cout<<"caught"<<e.what()<<endl;
}
return 0;

}
编译：
[root@:~/svn/mongoDB]#g++ main.cpp -lmongoclient -lboost_thread -lboost_filesystem -lboost_program_options

运行：
[root@:~/svn/mongoDB]#./a.out
connected ok

另一个测试：

#include <iostream>
#include "mongo/client/dbclient.h"

using namespace mongo;

int main() {

DBClientConnection conn;
BSONObj p = BSONObjBuilder().append("name", "Joe").append("age", 33).obj();

try {
conn.connect("localhost");
cout << "connected ok" << endl;
} catch( DBException &e ) {
cout << "caught " << e.what() << endl;
}

conn.insert("tutorial.persons", p);
conn.insert("tutorial.persons", p);
conn.insert("tutorial.persons", p);
return 0;
}

g++ -o mongo_insert mongo_insert.cpp -lmongoclient -lboost_thread -lboost_filesystem -lboost_program_options

$ ./insert mongoconnected ok

　　运行mongo客户端验证插入：

$ cd ~/usr/mongo/bin

$ ./mongo

MongoDB shell version: 1.8.2
connecting to: test
> show dbs

> use tutorial

> db.persons.find()
{ "_id" : ObjectId("4e11a582b918b66ebf3835fb"), "name" : "Joe", "age" : 33 }
{ "_id" : ObjectId("4e11a582b918b66ebf3835fc"), "name" : "Joe", "age" : 33 }
{ "_id" : ObjectId("4e11a582b918b66ebf3835fd"), "name" : "Joe", "age" : 33 }
>

　　OK，这样使用和开发都可以了。
