Mac下使用brew安装mongodb

2016-11-25 | Mac mongodb

MongoDB 是一个基于分布式文件存储的数据库。由 C++ 语言编写。旨在为 WEB 应用提供可扩展的高性能数据存储解决方案。

使用brew安装mongodb

brew install mongodb

如果不能开启服务

Failed to connect to 127.0.0.1:27017, reason: errno:61 Connection refused

Error: couldn't connect to server 127.0.0.1:27017 (127.0.0.1), connection attempt failed at src/mongo/shell/mongo.js:146

exception: connect failed

在启动mongo之前,需要创建一个目录，为mongo默认的数据写入目录

kyouhuamatoMac-mini:nodewebapp jinghua$ mkdir -p /Users/jinghua/demo/nodewebapp/data/db

刚刚创建的目录以可读可写的权限

kyouhuamatoMac-mini:nodewebapp jinghua$ chown `id -u` /Users/jinghua/demo/nodewebapp/data/db

可以放心启动mongod

mongod

出现报错信息：

2016-11-25T19:45:25.286+0800 I CONTROL  [initandlisten] dbexit:  rc: 100

在上面11行出现有报错信息：

意思是找不到/data/db文件位置

2016-11-25T19:45:25.286+0800 I STORAGE  [initandlisten] exception in initAndListen: 29 Data directory /data/db not found., terminating

需要创建新的文件，最好用sudo给它权限：

sudo mkdir -p /data/db

再执行运行：

mongod

又来了报错信息：

2016-11-25T20:11:22.128+0800 I CONTROL  [initandlisten] dbexit:  rc: 100

在上面第11行出现报错：

2016-11-25T20:11:22.128+0800 I STORAGE  [initandlisten] exception in initAndListen: 98 Unable to create/open lock file: /data/db/mongod.lock errno:13 Permission denied Is a mongod instance already running?, terminating

意思是不创建和打开/data/db/mongod.lock这个文件，原因是Permission denied（权限拒绝），需要给它操作目录权限

如下命令：

sudo chown -R  当前登录的用户名 /data

再执行运行启动：

mongod

然后在浏览器输入：http://localhost:27017/

在浏览器出现"It looks like you are trying to access MongoDB over HTTP on the native driver port."说明成功启动mongodb吧！
