树莓派体验（2）

今天开始折腾一下树莓派的环境。也作为今后的备忘

SSH连接树莓派

#ssh pi@192.168.1.110

确认树莓派系统版本

$ lsb_release -a
	No LSB modules are available.
	Distributor ID: Raspbian
	Description: Raspbian GNU/Linux 8.0 (jessie)
	Release: 8.0
	Codename: jessie

修改镜像地址为国内地址（http://blog.csdn.net/cduan/article/details/52594374）

$ sudo nano /etc/apt/sources.list
$ cat /etc/apt/sources.list
#deb http://mirrordirector.raspbian.org/raspbian/ jessie main contrib non-free rpi
deb http://mirrors.zju.edu.cn/raspbian/raspbian/ jessie main contrib non-free rpi

更新Raspbian软件环境

$ sudo apt-get update

安装Git环境

$ sudo apt-get install git
$ git config --global user.name "rex"
$ git config --global user.email 
$ git config --list

安装最新Node.js环境（http://qiita.com/setouchi/items/437e4b62e4210871496f）

$ sudo apt-get install -y nodejs npm
$ sudo npm cache clean
$ sudo npm install n -g
$ sudo n stable
$ sudo ln -sf /usr/local/bin/node /usr/bin/node
$ node -v
v7.2.1

安装MongoDB环境(http://andyfelong.com/2016/01/mongodb-3-0-9-binaries-for-raspberry-pi-2-jessie/)

$ wget http://andyfelong.com/downloads/core_mongodb.tar.gz
$ tar xvzf core_mongodb.tar.gz
$ sudo chown root:root mongo*
$ sudo chmod 775 mongo*
$ sudo strip mongo*
$ sudo cp -p mongo* /usr/bin
$ sudo mkdir /var/log/mongodb
$ sudo chown mongodb:nogroup /var/log/mongodb
$ sudo mkdir /var/lib/mongodb
$ sudo chown mongodb:root /var/lib/mongodb
$ sudo chmod 775 /var/lib/mongodb
$ cd /etc/
$ sudo vi mongodb.conf

# /etc/mongodb.conf
# minimal config file (old style)
# Run mongod --help to see a list of options

bind_ip = 127.0.0.1
quiet = true
dbpath = /var/lib/mongodb
logpath = /var/log/mongodb/mongod.log
logappend = true
storageEngine = mmapv1

$ cd /lib/systemd/system
$ sudo vi mongodb.service

建立Git远程仓库

登陆https://bitbucket.org/，申请一个账户和工程即可,之后本地Clone一份

$ git clone https://gitname@bitbucket.org/project.git

建立第一个Node.js+MongoDB例子(http://mongodb.github.io/node-mongodb-native/2.2/quick-start/)

$ mkdir myproject 
$ cd myproject
$ npm init
$ npm install mongodb --save
$ vi app.js

[html]var MongoClient = require(‘mongodb’).MongoClient  , assert = require(‘assert’);
// Connection URL
var url = ‘mongodb://localhost:27017/myproject’;

// Use connect method to connect to the server
MongoClient.connect(url, function(err, db) {
assert.equal(null, err);
console.log("Connected successfully to server");
db.close();
});[/html]

$ node app.js
    Connected successfully to server

$vi helloworld.js

[html]var http = require(‘http’);
http.createServer(function (request, response) {
response.writeHead(200, {‘Content-Type’: ‘text/plain’});
response.end(‘Hello World\n’);
}).listen(8124);
console.log(‘Server running at http://127.0.0.1:8124/’);[/html]

浏览器输入http://192.168.1.110:8124，能访问成功。基本就完成了！
把目前的程序都Push到远程仓库。

$ git add *
$ git commit -m "Hello RasperPi @2016.12.11"
$ git push origin master

今天到此为止。

sudo shutdown -h now
