Centos6.5安装配置Mongodb

mongodb官网上下载最新版本的mongodb，按照官网上的说明进行安装。

首先运行如下命令：

1	curl -O http://downloads.mongodb.org/linux/mongodb-linux-x86_64-2.6.3.tgz

其次，运用tar 进行解压缩，按照如下命令

1	tar -zxvf mongodb-linux-x86_64-2.6.3.tgz

第三，新建mongodb文件夹，把解压了的mongodb-linux-x86_64-2.6.3复制到mongodb下面。
按照如下命令

1 2	mkdir -p mongodb cp -R -n mongodb-linux-x86_64-2.6.3/ mongodb

第四，更改环境变量，在路径 /etc/下面，找到bashrc文件

1	export PATH=<mongodb-install-directory>:$PATH

替换成你的mongodb路径就可以了

第五，创建mongodb的dbdata的路径

1 2	mkdir -p /usr/local/mongo/data mongod --dbpath /usr/local/mongo/data

第六，进入mongo的文件夹，运行mongo命令，启动mongo就可以了。
上面的安装方法比较简单，但是有个问题，就是mongo启动必须同时制定data,也就是要运行mongod –dbpath /usr/local/mongo/data，比较繁琐，下面介绍一种一劳永逸的安装办法，把mongo的启动添加到服务当中。

创建配置文件

mkdir -p /usr/local/mongo/etc /usr/local/mongo/data /usr/local/mongo/log/ /usr/local/mongo/repair
vim  /usr/local/mongo/etc/mongo.conf
在mongo.conf中添加下面的内容
dbpath = /usr/local/mongo/data
logpath = /usr/local/mongo/mongodb.log
repairpath = /usr/local/mongo/repair
pidfilepath = /usr/local/mongo/mongodb.pid
directoryperdb = true
logappend = true
noauth = true
port = 27017
maxConns = 1024
fork = true
rest = true
quota = true
quotaFiles = 1024
nssize = 16

启动mongodb

1 2	ln -s /usr/local/mongo/bin/mongod /usr/bin/mongod mongod -f /usr/local/mongo/etc/mongo.conf

看看是不是启动起来了，但是使用这种方式管理mongodb服务器很不明智，我们完善一下：

1 2	mkdir -p /usr/local/mongo/srv vim /usr/local/mongo/srv/mongodb-start

添加下面的内容

1 2	#!/bin/sh mongod -f /usr/local/mongo/etc/mongo.conf

1	vim /usr/local/mongo/srv/mongodb-stop

添加下面的内容

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

添加执行权限

1
2
3

chmod a+x /usr/local/mongo/srv/mongodb-start
chmod a+x /usr/local/mongo/srv/mongodb-stop
vim /etc/rc.d/init.d/mongodb

添加下面的内容

#! /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: /usr/local/mongo/etc/mongo.conf
# pidfile: /usr/local/mongo/mongodb.pid
PATH=/usr/local/mongo/bin:/sbin:/bin:/usr/sbin:/usr/bin
NAME=mongodb
test -x $DAEMON || exit 0
set -e
case "$1" in
  start)
        echo -n "Starting MongoDB... "
        /usr/local/mongo/srv/mongodb-start
        ;;
  stop)
        echo -n "Stopping MongoDB... "
        /usr/local/mongo/srv/mongodb-stop
        ;;
      *)
            N=/etc/init.d/$NAME
            echo "Usage: $N {start|stop}" >&2
            exit 1
            ;;
    esac
    exit 0

添加服务

chmod a+x /etc/rc.d/init.d/mongodb
chkconfig --add mongodb
chkconfig --level 345 mongodb on
/etc/rc.d/init.d/mongodb start
