## 部署服务器
阿里云
ubuntu 14.10 LTS 64位
## 登录远端服务器
ssh root@ip
## 创建用户
~~~
# sudo useradd -m -d /home/sang -s /bin/bash -c "the sang user" -U sang
# passwd sang
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
~~~
* useradd创建登录用户
* passwd设置用户登录密码
## 赋予sudo权限
如果有必要使用sudu权限，请修改
~~~
# sudo vi /etc/sudoers
~~~
复制root行改为sang即可
~~~
# User privilege specification
root ALL=(ALL:ALL) ALL
sang ALL=(ALL:ALL) ALL
~~~
## 切换用户
~~~
# su - sang
$ ls
$
$ pwd
/home/sang
$
~~~
## 安装必备软件
### 安装git
如果上面没有复制给sang账户sudo权限，请切换到root账户操作
~~~
sudo apt-get update
sudo apt-get install git
~~~
### 安装nginx
~~~
sudo apt-get install nginx
~~~
### 开机启动
（[http://www.jianshu.com/p/2e03255cfabb）](http://www.jianshu.com/p/2e03255cfabb%EF%BC%89)
~~~
sudo apt-get install sysv-rc-conf
sudo sysv-rc-conf nginx on
~~~
注意：Ubuntu系统中服务的运行级别
* 0 系统停机状态
* 1 单用户或系统维护状态
* 2~5 多用户状态
* 6 重新启动
### 准备工作目录
~~~
mkdir -p workspace/github
cd workspace/github
~~~
## 安装nodejs
### 安装nvm
~~~
$ curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.31.0/install.sh | bash
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
100 7766 100 7766 0 0 28614 0 --:--:-- --:--:-- --:--:-- 28656
=> Downloading nvm as script to '/home/sang/.nvm'
=> Appending source string to /home/sang/.bashrc
=> Close and reopen your terminal to start using nvm
$ source ~/.bashrc
$ nvm
Node Version Manager
~~~
安装nodejs lts版本
~~~
$ nvm install 4
Downloading https://nodejs.org/dist/v4.3.2/node-v4.3.2-linux-x64.tar.xz...
######################################################################## 100.0%
Now using node v4.3.2 (npm v2.14.12)
Creating default alias: default -> 4 (-> v4.3.2)
$ node -v
v4.3.2
~~~
使之成为默认
~~~
$ nvm alias default 4.3
default -> 4.3 (-> v4.3.2)
~~~
### 确认npm版本
~~~
$ npm -v
2.14.12
~~~
只要大于2.9.1即可，如不是，请`npm i -g npm@2.9.1`
### 安装nrm
~~~
$ npm i -g nrm

~~~
## 部署nodejs应用
### 基础
* git clone
* npm i
* pm2 start
### 修改nginx
~~~
cat /etc/nginx/sites-enabled/default
upstream backend_nodejs {
server 127.0.0.1:3019 max_fails=0 fail_timeout=10s;
#server 127.0.0.1:3001;
keepalive 512;
}
server {
listen 80 default_server;
listen [::]:80 default_server ipv6only=on;
#root /usr/share/nginx/html;
root /home/sang/workspace/oschina/base2-wechat-jssdk/public;
index index.html index.htm;
# Make site accessible from http://localhost/
server_name nodeonly.mengxiaoban.cn at35.com;
client_max_body_size 16M;
keepalive_timeout 10;
location / {
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
#try_files $uri $uri/ =404;
# Uncomment to enable naxsi on this location
# include /etc/nginx/naxsi.rules
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_set_header X-NginX-Proxy true;
proxy_redirect off;
proxy_next_upstream error timeout http_500 http_502 http_503 http_504;
proxy_set_header Connection "";
proxy_http_version 1.1;
proxy_pass http://backend_nodejs;
}
}
~~~
注意
* upstream backend_nodejs定义的代理转发的api地址
* location /下面的proxy_pass，从upstream里取
* root下面放的是静态资源，比如express下的public目录
然后重启nginx即可
~~~
sudo nginx -s reload
~~~
### 了解MONGODB的部署
* replset
* shard
我写的《 mongodb运维之副本集实践》
[https://cnodejs.org/topic/5590adbbebf9c92d17e734de](https://cnodejs.org/topic/5590adbbebf9c92d17e734de)
on ubuntu
[https://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/](https://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/)
## 代码部署
ssh免登陆
~~~
git clone git@git.oschina.net:i5ting/wechat-dev-with-nodejs.git
~~~
* 调整nginx
* pm2
## node的代码

源码介绍的时候，穿插robo和dash用法
### 测试
user
~~~
var request = require('supertest');
var assert = require('chai').assert;
var expect = require('chai').expect;
require('chai').should();
require('../db')
var User = require('../app/models/user')
// 测试代码基本结构
describe('用户User', function(){
before(function(d) {
// runs before all tests in this block
User.remove({"openid":"ss"},function(){
d()
})
})
after(function(){
// runs after all tests in this block
// User.remove({},function(err, user){
// });
})
beforeEach(function(){
// runs before each test in this block
})
afterEach(function(){
// runs after each test in this block
})
describe('#save()', function(){
this.timeout(30000);
it('should return stuq when user save', function(done){
User.create({"username":"stuq","password":"password", "openid":"ss"},function(err, user){
if(err){
console.log(err)
expect(err).to.be.not.null;
done();
}
expect(user.username).to.be.a('string');
expect(user.username).to.equal('stuq');
done();
});
})
})
})
~~~
用户与课程
~~~
var request = require('supertest');
var assert = require('chai').assert;
var expect = require('chai').expect;
require('chai').should();
require('../db')
var User = require('../app/models/user')
var Course = require('../app/models/course')
var Order = require('../app/models/order')
var _user;
// 测试代码基本结构
describe('课程Course', function(){
before(function(done) {
// runs before all tests in this block
User.removeAsync({"username":"stuq","password":"password", "openid":"ss"}).then(function(){
return User.createAsync({"username":"stuq","password":"password", "openid":"ss"})
}).then(function(user){
_user = user;
return Course.removeAsync({"name":"Node.js微信开发"});
}).then(function(){
done();
});
})
after(function(){
// runs after all tests in this block
// User.remove({},function(err, user){
// });
})
beforeEach(function(){
// runs before each test in this block
})
afterEach(function(){
// runs after each test in this block
})
describe('#save()', function(){
it('should return Node.js微信开发 when Course save', function(done){
Course.create({
"name":"Node.js微信开发","desc":"stuq在线课程", "docent":"桑世龙", owner_id: _user._id,
desc:"通过学习Node.js基础和express，微信开发常用库，h5，最后达到学会Node.js开发的目的，该课程以实战为主，深入浅出"
},function(err, c){
if(err){
console.log(err)
expect(err).to.be.not.null;
done();
}
expect(c.name).to.be.a('string');
expect(c.name).to.equal('Node.js微信开发');
done();
});
})
})
})
~~~
三个表相关的订单
~~~
var request = require('supertest');
var assert = require('chai').assert;
var expect = require('chai').expect;
require('chai').should();
require('../db')
var User = require('../app/models/user')
var Order = require('../app/models/order')
var Course = require('../app/models/course')
var _user, _course;
// 测试代码基本结构
describe('订单Order', function(){
before(function(done) {
// runs before all tests in this block
User.removeAsync({"openid":"ss1"}).then(function(){
return Course.removeAsync({"name":"Node.js微信开发1"});
}).then(function(){
User.create({"username":"stuq1","password":"password", "openid":"ss1"},function(err, user){
_user = user;
// console.log(err)
// console.log(_user)
return Course.create({"name":"Node.js微信开发1","desc":"stuq在线课程", "docent":"桑世龙", owner_id: _user._id},function(err1, c){
// console.log(c)
_course = c;
done();
});
});
})
})
after(function(){
})
beforeEach(function(){
// runs before each test in this block
})
afterEach(function(){
// runs after each test in this block
})
describe('#save()', function(){
it('should return order when order save', function(done){
Order.create({
"desc":"a order"
,"user_id":_user._id
, "user_name": _user.username
,course_id : _course._id
,course_name : _course.name
},function(err, order){
if(err){
console.log(err)
expect(err).to.be.not.null;
done();
}
expect(order.desc).to.be.a('string');
expect(order.desc).to.equal('a order');
done();
});
})
})
})
~~~
另外举例runkoa没有ci引发的血案
### api
自动挂载路由
~~~
var mount = require('mount-routes');
// simple
mount(app, __dirname + '/app/routes');
~~~
示例
~~~
var express = require('express');
var router = express.Router();
var User = require('../../models/user')
var Course = require('../../models/course')
var Order = require('../../models/order')
router.get('/', function(req, res, next) {
Course.find({},function(err, courses){
res.json({
status:{
code:0,
msg:'sucess'
},
data:courses
});
});
})
module.exports = router;
~~~
测试
~~~
curl http://127.0.0.1:3019/api/courses
~~~
或者`postman`
## 前端weui代码
weui v0.4.x新增了路由和tab等组件，问题还是挺多的
frontend目录随便配，目的就是为了让大家理解前后端分离
### 路由
定义骨架
~~~
var router = new Router({
container: '#container',
enterTimeout: 250,
leaveTimeout: 250
});
~~~
然后
~~~
// course
var course = {
url: '/course',
className: 'panel',
render: function () {
// alert(getQueryStringByName('id'));
return $('#tpl_course').html();
},
bind: function () {
$('.pay_btn').on('click', function(){
var id = getQueryStringByName('id');
pay_h5(id);
})
}
};
// tabbar
var tabbar = {
url: '/home',
className: 'tabbar',
render: function () {
var _t = this;
setTimeout(function(){
_t.bind()
},100)
return $('#tpl_tabbar').html();
},
bind: function () {
$('.course_list').html(all_courses_html);
$('.weui_tabbar_content').eq(0).show()
$('.weui_tabbar_item').on('click', function () {
$('.weui_tabbar_item').eq($('.weui_tabbar_item').index(this)).addClass('weui_bar_item_on').siblings().removeClass('weui_bar_item_on')
$('.weui_tabbar_content').eq($('.weui_tabbar_item').index(this)).show().siblings().hide();
});
}
};
router.push(tabbar)
.push(course)
.setDefault('/home')
.init();
~~~
### example.js
根据query的参数名，取值
~~~
function getQueryStringByName(name){
var result = location.hash.match(new RegExp("[\?\&]" + name+ "=([^\&]+)","i"));
if(result == null || result.length < 1){
return "";
}
return result[1];
}
~~~
ajax
~~~
var all_courses_html;
$.getJSON('/api/courses',function(res){
// alert(res)
var item_html = ""
for(var i in res.data){
console.log(i);
var course = res.data[i];
var item = " "
+"
';
"
+" ![](" + course.pic + ")
"
+"
"
+" "
+"
"
+" "
item_html += item;
}
all_courses_html = "" + course.name + "
" +"" + course.desc + "
" +" " + item_html + "
查看更多"
// alert(all);
$('.course_list').html(all_courses_html);
})
~~~
这样首页是ok了，但是里面呢？
~~~
// tabbar
var tabbar = {
url: '/home',
className: 'tabbar',
render: function () {
var _t = this;
setTimeout(function(){
_t.bind()
},100)
return $('#tpl_tabbar').html();
},
bind: function () {
$('.course_list').html(all_courses_html);
$('.weui_tabbar_content').eq(0).show()
$('.weui_tabbar_item').on('click', function () {
$('.weui_tabbar_item').eq($('.weui_tabbar_item').index(this)).addClass('weui_bar_item_on').siblings().removeClass('weui_bar_item_on')
$('.weui_tabbar_content').eq($('.weui_tabbar_item').index(this)).show().siblings().hide();
});
}
};
~~~
* setTimeout
* $('.course_list').html(all_courses_html);
### 实现tab
~~~
~~~
留意weui_tabbar_content
~~~
$('.weui_tabbar_content').eq(0).show()
$('.weui_tabbar_item').on('click', function () {
$('.weui_tabbar_item').eq($('.weui_tabbar_item').index(this)).addClass('weui_bar_item_on').siblings().removeClass('weui_bar_item_on')
$('.weui_tabbar_content').eq($('.weui_tabbar_item').index(this)).show().siblings().hide();
});
~~~

## 总结
### 关于StuQ
软件公司招聘需要巨大，但入门难，技术发展过快（指数），而人的曲线成长较慢，现在的慕客形式又过于老旧，呆板，少互动，所以社群时代的在线教育，一定是专业的、互动的、深入浅出、共同成长，这些正是StuQ最擅长的方面，我个人特别看好StuQ这个品牌，真心推荐，如果不是股份绑定，我一定会加入StuQ
### 我的近况
* 新书《更了不起的 Node 4:将下一代 Web 框架 Koa 进行到底》，预计2到3个月就能和大家见面
* StuQ-Koa在线课程，准备招生
## 写给大家
* 学不学在自己，会不会也在自己
* 少抱怨、多思考、未来更美好
* 闲时要有吃紧的心思
* 一万个小时就能成为专家，难在坚持
* 掌握了学习方法，以后职业不愁
