虚拟主机没有性价比,所以迁移到aws(ubuntu 12.04 x64).

全流程如下

#安装服务

sudo apt-get install apache2
sudo apt-get install mysql-server mysql-client
sudo apt-get install php5 php5-gd php5-mysql php5-curl
sudo apt-get install phpmyadmin

#rewrite 模块
sudo a2enmod rewrite

#编辑配置文件
sudo vi /etc/apache2/apache2.conf

#添加以下行后保存退出(也许未必需要)
ServerName 127.0.0.1
AddDefaultCharset UTF-8
AddType application/x-httpd-php .php .htm .html

#进入数据库
/usr/bin/mysql -u root -p

#建立数据库
CREATE DATABASE databasename;
CREATE USER databaseuser@localhost;
SET PASSWORD FOR databaseuser@localhost= PASSWORD("databasepassword");
GRANT ALL PRIVILEGES ON databasenamel5beta.* TO databaseuser@localhost IDENTIFIED BY 'databasepassword';
FLUSH PRIVILEGES;

#导入数据库

use databasename
source link-to-your-sql.sql

#### aws 需要使用/swap来避免数据库crash ####
sudo dd if=/dev/zero of=/swapfile bs=1M count=1024
sudo mkswap /swapfile
sudo swapon /swapfile

#### 在/etc/fstab中加入
/swapfile swap swap defaults 0 0

#文件目录
mkdir wordpress
cd wordpress
tar -xzvf your-wordpress-files.tar.gz .

#权限
sudo chown -R www-data .

#链接
sudo ln -s your-path-to/wordpress /var/www

#编辑 virtual host

##从默认复制一份
sudo cp /etc/apache2/sites-available/default /etc/apache2/sites-available/your-host-name.com

##编辑
sudo vi /etc/apache2/sites-available/your-host-name.com

##添加
ServerName your-host-name.com
ServerAlias www.your-host-name.com
DocumentRoot /var/www/wordpress

##保存退出后,添加站点
sudo a2ensite wordpress

#修改 /etc/apache2/sites-available/default 
#和 /etc/apache2/sites-available/your-host-name.com 的 
#<Directory /var/www/>
AllowOverride All

#重启服务
sudo service apache2 restart

#最后解析域名到主机ip,完成

default settings of phonegap webview is really not like a normal browser.
I googled a lot to get it right.
here is the tips
in your main java file of phongap project ,
add these:

WebSettings settings = appView.getSettings(); 
settings.setPluginsEnabled(true);// Turn Flash plugin on, but you must install flash plugin yourself
settings.setBuiltInZoomControls(true);
settings.setSupportZoom(true);
settings.setDefaultZoom(ZoomDensity.MEDIUM); 
settings.setUseWideViewPort(true);
settings.setLoadWithOverviewMode(true);

after the line:
super.loadUrl(Config.getStartUrl());

Demo

jsonp weather data demo

服务器端

用php获取 http://m.weather.com.cn/data/101010100.html 的json数据并以jsonp格式返回给前端

  <?php
     $id = $_GET['id'];//前端提交id, 如 101010100,参见城市代码
     $cb = $_GET['callback']; //前端提交 callback function name,据此构造返回 function
     $jp = 'http://m.weather.com.cn/data/'. $id .'.html'; //url
     $contents = file_get_contents($jp); //获取json
     echo $cb. '(' .$contents . ')'; //返回
  ?>
  

参考 http://sae.sina.com.cn/?m=devcenter&catId=211,部署到SAE

阿里云的价格不错,定制使用部署都很方便。
昨天刚部署了一个ubuntu 12.04,nodejs,proftpd 的组合,写个流程记录。

 连接服务器

ssh root@server_ip

 初始化数据盘

参照
Linux 系统挂载数据盘

 Installing Node.js via package manager

参照
Installing Node.js via package manager

apt-get install python-software-properties python g++ make
add-apt-repository ppa:chris-lea/node.js
apt-get update
apt-get install nodejs npm

z注意:可能提示你未安装python之类,按照提示apt-get相应软件,然后apt-get update

安装express

npm install express -gd

初始化网站目录

cd /mnt/
express nodeserver
cd nodeserver
npm install

然后得编辑下 app.js

vi app.js

进入vi界面,基本操作:
i 进入编辑,编辑完毕 按 ESC 键退出编辑,
:w 保存,
:q 退出vi。

  1. 先把默认端口号 3000 改为 80

    app.set('port', process.env.PORT || 80);
    
  2. 纯静态服务的话注释掉以下代码
    //app.get('/', routes.index);
    //app.get('/users', user.list);
    

然后用forever 实现后台启动nodejs,这样就可以安全关掉ssh(-w 参数实现监视文件更改 )

npm install forever
forever start -w app.js

这样服务就启动了,可以用ip访问试试。

安装proftpd,以便ftp上传文件

apt-get install proftpd

可能会提示要安装其他倚赖关系的软件。记不清了,记得用standalone方式。容易一些。

参考:

http://blog.csdn.net/id19870510/article/details/8395339

然后部署用户


//用户组
groupadd ftpusergroup

//添加用户
useradd ftpuser -d /mnt/nodeserver/ -g ftpusergroup

//设置密码
passwd ftpuser

// 修改 proftpd配置文件

vi /etc/proftpd/proftpd.conf

// 去掉如下行前的注释 #

# DefaultRoot ~

//用户权限
chown ftpuser /mnt/nodeserver/*

用客户端登陆试试,大功告成,上传文件即可。

不支持ie6,用现代浏览器吧。 firefox, google chrome, opera, safari 等,或请升级到 更高版本的Internet Explorer
