3 mkdir -p /data/db/	//默认会在/data/db/存储数据库文件
4 chown `id -u` /data/db
**5 chown -R  mongodb:mongodb db/** 这个可重要了
6 ./mongod

OR

1 sudo apt-get install mongodb-10gen

设置开机启动

以下这个是要自己写，要是应用apt-get install 的话是不需要的。

/etc/init.d/mongodb

关闭/启动服务

sudo service mongodb stop
sudo service mongodb start

`http://192.168.6.129:27017/`
You are trying to access MongoDB on the native driver port. For http diagnostic access, add 1000 to the port number

手动粗暴启动mongodb server

1
2

./mongod -journal -maxConns=2400 -rest
-journal 代表要写日志，-maxConns=2400代表mongodb 可以接受2400个tcp连接，-rest代表可以允许客户端通过rest API访问mongdb server.
还可以使用参数—quiet启动可以指定安静模式减少记录的项目数，注意使用该参数必须要同时指定日志路径,比如：
—quiet —logpath /data/db/journal/mongdb.log

修改系统允许的最大连接数

上面的最大连接数目的限制原因是Linux系统默认一个进程最大文件打开数目为1024，用ulimit -a 命令检查，可以看到下面这行:
open files                      (-n) 1024

修改/etc/security/limits.conf 配置文件。
使用命令：sudo gedit /etc/security/limits.conf
在文件中增加
* soft nofile 3000
* hard nofile 20000
root soft nofile 3000
root hard nofile 20000
* 表示该配置对所有用户均有效,root用户要特别加两行。
硬限制通常是根据系统硬件资源状况(主要是系统内存)计算出来的系统最多可同时打开的文件数量，软限制是在这个基础上进一步的限制。因此软限制数目要低于硬限制。
nofile表示 max number of open files
重新启动计算机，然后再用ulimit -a 命令查看：
open files                      (-n) 3000
已经生效了。现在再启动mongodb server，问题解决

客户端登录服务器

启动日志如上，服务端启动如上，现在我们在另外一个终端测试服务器是否正常。
进入/usr/local/mongodb-linux-x86_64-2.0.2/bin,执行./mongo
出现

1
2

MongoDB shell version: 2.0.2
connecting to: test

执行

3

$db.foo.save({1 : “Hello world”})
$db.foo.find();
{ "_id" : ObjectId("4e4b395986738efa2d0718b9"), "1" : "hello world" }

执行到这里恭喜你，成功安装好了mongodb

也可以通过下面这种方式连接远程的mongodb server,默认端口为27017,比如 ./mongo 192.168.6.129

创建数据库

如果没有mydb数据库的话，在客户端中使用命令：
use mydb
将创建mydb数据库，而且当前数据库切换为mydb.
此时show dbs不显示该数据库名称。使用db.stats()命令检查当前数据库状态。

1

$db     当前数据库

标准检查流程

  • 1.首先检查 ulimit -a 查看open files (-n) 是否为设置的值
  • 2.ps -def | grep mongod 查看该服务是否启动
  • 3.cd /var/log/ cat mongdb.log
    查看服务器是否正确
  • 4.进入http://192.168.6.129:28017 看服务器是否启动正常
