编译安装MongoDB

一、安装PCRE库

PCRE(Perl Compatible Regular Expressions)，提供高速的正则表达式匹配api。

yum install pcre-devel

或者到ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/下载合适的pcre源码包，然后configure/make/make install

二、安装Spider Monkey库

SpiderMonkey是JavaScript的C实现，可以提供JavaScript的代码解释功能。

到ftp://ftp.mozilla.org/pub/mozilla.org/js/下载js压缩包，解压后进入src目录，并按照如下步骤进行编译安装：

export CFLAGS=”-DJS_C_STRINGS_ARE_UTF8″make -f Makefile.refJS_DIST=/usr make -f Makefile.ref export

三、安装SCons

Scons是一个Python写的自动化构建工具，比传统的GNU make更加简便、可靠以及高效。

到http://sourceforge.net/projects/scons/files/scons/下载源码压缩包，解压之后按照如下步骤进行安装：

python setup.py install

四、安装MongoDB

先到http://www.mongodb.org/downloads/下载想要的MongoDB版本。建议下载1.6以上，有很多架构和功能方面的改进。

解压缩之后按照如下步骤进行安装：

scons allscons –prefix=/usr/local/mongodb install

如果想要头文件和lib包，执行

scons –prefix=/usr/local/mongodb –full install

五，让MongoDB跑起来

虽然MongoDB支持在命令行里面添加所有参数，但是为了管理方便，还是应该添加一个配置文件的。然后在命令行里面指定配置文件的位置。

下面是一个简单的配置文件：

vim /usr/local/mongodb/config/mongodb#Directory and relavent setdbpath = /usr/local/mongodb/datalogpath = /usr/local/mongodb/log/mongodb.logrepairpath = /usr/local/mongodb/repairpidfilepath = /usr/local/mongodb/mongodb.piddirectoryperdb = true#sysinfo = true#verbose = truelogappend = true#cpu = true#Network and security setnoauth = trueport = 8888maxConns = 1024fork = true#Management#nohttpinterface = truerest = truequota = truequotaFiles = 1024nssize = 16#syncdelay = 5

值得注意的是，类似 nohttpinterface = false 的配置是无效的。因为这些选项默认为false，不需要配置。

运行MongDB：

mongod –config /usr/local/mongodb/config/mongodb

启动脚本 mongodb-start.sh

#!/bin/sh/usr/local/mongodb/bin/mongod --config /usr/local/mongodb/config/mongodb ## --upgrade \ ##runs a database upgrade option if needed \

关闭脚本 mongodb-stop.sh

#!/bin/bashpid=`ps -o pid,command ax | grep mongod | awk '!/awk/ && !/grep/ {print $1}'`;if [ "${pid}" != "" ]; thenkill -2 ${pid};fi

六，做服务

启动脚本init-rpm.sh

#! /bin/sh## mongodb – this script starts and stops the mongodb daemon## chkconfig: - 85 15# description: MongoDB is a non-relational database storage system.# processname: mongodb# config: /opt/config/mongodb# pidfile: /opt/mongodb/mongo.pidPATH=/opt/mongodb/bin:/sbin:/bin:/usr/sbin:/usr/binNAME=mongodbtest -x $DAEMON || exit 0set -ecase "$1" instart)echo -n "Starting MongoDB... "su - mongodb -c "/opt/bin/mongodb-start";;stop)echo -n "Stopping MongoDB"/opt/bin/mongodb-stop;;*)N=/etc/init.d/$NAMEecho "Usage: $N {start|stop}" >&2exit 1;;esacexit 0

把以上启动脚本做成服务

#mv init-rpm.sh /etc/init.d/mongodb#chmod +x /etc/init.d/mongodb#chkconfig --add mongodb#chkconfig -–level 345 mongodb on

MongoDB与sql语句对照表

SQL Statement

Mongo Query Language Statement

CREATE TABLE USERS (a Number, b Number) implicit; can be done explicitly

INSERT INTO USERS VALUES(1,1) db.users.insert({a:1,b:1})

SELECT a,b FROM users db.users.find({}, {a:1,b:1})

SELECT * FROM users db.users.find()

SELECT * FROM users WHERE age=33 db.users.find({age:33})

SELECT a,b FROM users WHERE age=33 db.users.find({age:33}, {a:1,b:1})

SELECT * FROM users WHERE age=33 ORDER BY name db.users.find({age:33}).sort({name:1})

SELECT * FROM users LIMIT 1 db.users.findOne()

EXPLAIN SELECT * FROM users WHERE z=3 db.users.find({z:3}).explain()

SELECT DISTINCT last_name FROM users db.users.distinct('last_name')

SELECT COUNT(*y) FROM users db.users.count()

SELECT COUNT(*y) FROM users where AGE > 30 db.users.find({age: {'$gt': 30}}).count()

SELECT COUNT(AGE) from users db.users.find({age: {'$exists': true}}).count()

UPDATE users SET a=1 WHERE b='q' db.users.update({b:'q'}, {$set:{a:1}}, false, true)

UPDATE users SET a=a+2 WHERE b='q' db.users.update({b:'q'}, {$inc:{a:2}}, false, true)

DELETE FROM users WHERE z="abc" db.users.remove({z:'abc'});
