SSL Certificate Installation on Nginx or Apache

Log — Tags: Apache, Nginx, SSL — Posted by Starck on January 11, 2014

SSL Certificate

Before we can sign up for a certificate we have to generate a RSA private key

openssl genrsa -des3 -out example.com_secure.key 2048

1	openssl genrsa -des3 -out example.com_secure.key 2048

You will be prompted to provide a passphrase(required). The key file is secured with this passphrase but we will eventually remove this protection.

Then, we will use this private key to generate a certificate signing request which is then submitted to the CA.

openssl req -new -key example.com_secure.key -out example.com.csr

1	openssl req -new -key example.com_secure.key -out example.com.csr

Remove the encryption from the RSA private key

Before we start configuring HTTPS Server we have to make sure to remove the passphrase from our RSA key. Otherwise you have to provide the password every time server started.

openssl rsa -in example.com_secure.key -out example.com_secure.key

1	openssl rsa -in example.com_secure.key -out example.com_secure.key

The unencrypted private key should only be readable by the owner of the Nginx or Apache master process. Most of the time this is the root user:

chmod 400 example.com_secure.key
sudo chown root:root example.com_secure.key

1 2	chmod 400 example.com_secure.key sudo chown root:root example.com_secure.key

Generate SSL Certificate

openssl x509 -req -days 365 -in example.com_secure.csr -signkey example.com_secure.key -out example.com_secure.crt

1	openssl x509 -req -days 365 -in example.com_secure.csr -signkey example.com_secure.key -out example.com_secure.crt

Setting up server

Nginx

server {

    listen 443;
    server_name example.com;
    root /var/www/example.com

    ssl on;
    ssl_certificate /path/example.com_secure.crt;
    ssl_certificate_key /path/example.com_secure.key;

}

server {

listen 443;

server_name example.com;

root /var/www/example.com

ssl on;

ssl_certificate /path/example.com_secure.crt;

ssl_certificate_key /path/example.com_secure.key;

}

Apache

<VirtualHost *:443>
    DocumentRoot /var/www/example.com
    SSLEngine on
    SSLCertificateFile /path/example.com_secure.crt
    SSLCertificateKeyFile /path/example.com_secure.key
    SSLCertificateChainFile /path/example.com_secure.crt
</VirtualHost>

DocumentRoot /var/www/example.com

SSLEngine on

SSLCertificateFile /path/example.com_secure.crt

SSLCertificateKeyFile /path/example.com_secure.key

SSLCertificateChainFile /path/example.com_secure.crt

Why it’s so dang hard to stick to a resolution

Log — Tags: TED, Thinking — Posted by Starck on January 9, 2014

“Ask yourself what you want for yourself and your life in the next year. What is it that you want to offer the world? Who do you want to be, what do you want more of in your life? And then ask: How might I get there?”

Psychologist Kelly McGonigal explains how to make resolutions that lead to real change:

Building Your Jsbin Service

Log — Tags: jsbin, node — Posted by Starck on November 2, 2013

Install node and npm
Install jsbin

npm install jsbin or npm install -g jsbin

if have node not found problem, link it to `/usr/bin

ln -s /usr/local/bin/node /usr/bin/node
Clone jsbin project form github

git clone [email protected]:remy/jsbin.git
Jsbin configuration settings

Go to jsbin project folder

cp config.default.json config.local.json and modify it. mkdir tmp; mkdir tmp/pids and chmod 777 tmp/pids
Install init.d script

vim /etc/init.d/jsbin and chmod +x /etc/init.d/jsbin

Change {userid} to your user id.

Backbone.js notes

Coding, Log — Tags: backbone.js, javascript — Posted by Starck on October 18, 2013

Backbone.Events

var evtObj = {}
_.extend( evtObj, Backbone.Events );

1 2	var evtObj = {} _.extend( evtObj, Backbone.Events );

Method	Note
object.on(event, callback, [context])	註冊監聽一個事件, 並指定觸發 callback, 如果需要在 callback function 中改變 this 的對象, 將對象傳入 context
object.off([event], [callback], [context])	取消監聽事件, 不指定事件將取消所有的事件

Backbone Event Testing

Backbone.Model

var Model = Backbone.Model.extend({
});

var ChildModel = Model.extend({
});

var Model = Backbone.Model.extend({

});

var ChildModel = Model.extend({

});

Properties / Method	Note
constructor()	You can use `Backbone.Model.apply(this, arguments)` to invoke constructor function of parent class
initialize()	If you definean initialize function, it’ll be invoked when the model is created.
defaults	Remember that in JavaScript, objects are passed by reference, so if you include an object as a default value, it will be shared among all instances. Instead, define defaults as a function.
attributes	If you’d like to retrieve and munge a copy of the model’s attributes, use `_.clone(model.attributes)` instead.
validate(attrs, options)	By default validate is called before save, but can also be called before set if `{validate:true}` is passed. Return your custom error message, and it will be stored to `validateError`
isValid()	Run `validate()` to check the model state.
validationError	The value returned by validate during the last failed validation.
`set()` `get()`	set(‘attr’, ‘value’) or set({ attr: value})
destroy()	You can use `_.invoke()` to call destroy function for a batch of models. ex: `_.invoke(modelsArray, 'destroy')`

Backbone.Collection

create({ attr: value })
fetch()

var Collection = Backbone.Collection.extend({
})

1 2	var Collection = Backbone.Collection.extend({ })

Properties / Method	Note
model
url
models	Raw access to the JavaScript array of models inside of the collection.
add
create
reset

Project Template

Backbone.View

var View = Backbone.View.extend({
});

1 2	var View = Backbone.View.extend({ });

Properties / Method	Note
tagName
id
className
attributes
el and $el
events
render()	A good convention is to return this at the end of render to enable chained calls.

Backbone JS Data Types Primer

Backbone.LocalStorage

localStorage: new Backbone.LocalStorage("SomeCollection"), // Unique name within your app.

1	localStorage: new Backbone.LocalStorage("SomeCollection"), // Unique name within your app.

Example: TodoList

{embed="path/template"}

// 若要用 Variable 可以改採 Snippet 的方式

// 定義 {layout} -> embed="path/template"

// 使用:

取得 channel 的文章, 並顯示 channel custom field 值

{exp:channel:entries channel="events" limit="10"}

    {absolute_count}

{/exp:channel:entries}

{exp:channel:entries channel="events" limit="10"}

{channel_custom_field}

// 每一次迴圈會使 absolute_count + 1

{absolute_count}

編寫 Plugin file:

假設我們今天要建立的 Plugin 名稱叫作 Custom

先在 third_party 資料夾底下建立 custom 資料夾命名為 pi.custom.php .

    'pi_author_url'     => 'http://beyond.com.tw/',
    'pi_description'    => 'this is a plugin for demo',
    'pi_usage'          =>  Custom::usage()

);

Class Custom {

    function __construct() {
        $this->EE =& get_instance();
    }

    // Single Tag
    // {exp:custom:single_line_tag key='key' value='value'}

        $key = $this->EE->TMPL->fetch_para('key');
        $value = $this->EE->TMPL->fetch_para('value');
        return $key.' : '.$value;
    }

    // Tag Block

Module

upd.module_name.php

// 安裝 module 時被呼叫的 method
function __construct() {
    $this->EE =& get_instance();
}

function install() {
    $data = [
        'module_name' => 'Beyond',
        'module_version' => $this->version,
        'has_cp_backend' => 'y',
        'has_publish_fields' => 'y',
        'settings' => ''
    ];
    $this->EE->db->insert('modules', $data);

    // return TRUE or FALSE
    return TRUE:
}
// 解除安裝 module 時被呼叫的 method
function uninstall() {
    $this->EE->db->where('module_name', 'Beyond')->delete('modules');
    // return TRUE or FALSE
    return TRUE;
}

// 安裝 module 時被呼叫的 method

function __construct() {

$this->EE =& get_instance();

}

function install() {

$data = [

'module_name' => 'Beyond',

'module_version' => $this->version,

'has_cp_backend' => 'y',

'has_publish_fields' => 'y',

'settings' => ''

];

$this->EE->db->insert('modules', $data);

// return TRUE or FALSE

return TRUE:

}

// 解除安裝 module 時被呼叫的 method

function uninstall() {

$this->EE->db->where('module_name', 'Beyond')->delete('modules');

// return TRUE or FALSE

return TRUE;

}

mcp.module_name.php

mcp 就是 module 的 controller, 假設一個被請求的 url 如下:

admin.php?D=cp&C=addons_modules&M=show_module_cp&module=beyond&method=

C=addons_modules 代表目前的 Controller 是 expression/controllers/cp/addons_modules.php

M=show_module_cp 代表使用該 controller 的 show_module_cp 這個 method

module=beyond 代表被呼叫的 module id名稱為 beyond (third_party/{module_id})

method= 執行該 module controller 的哪一個 method, 未指定預設會導向 index method


C=addons_modules	代表目前的 Controller 是 expression/controllers/cp/addons_modules.php
M=show_module_cp	代表使用該 controller 的 show_module_cp 這個 method
module=beyond	代表被呼叫的 module id名稱為 beyond (third_party/{module_id})
method=	執行該 module controller 的哪一個 method, 未指定預設會導向 index method

透過指定 method 這個 GET 變數，將改變 module controller 呼叫不同的 method, 另外你也可以外部讀取 template 產生不同的 view, 將這些 templates 放置在 module/views 裡, 透過以下在 module controller 的 method 中回傳:

return $this->EE->load->view('template_name', $vars, TRUE);

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Beyond_mcp {

    function __construct() {
        $this->EE =& get_instance();
        // $this->EE->load('view');
    }

    // admin.php?D=cp&C=addons_modules&M=show_module_cp&module=beyond&method=
    function index() {

        return $this->EE->load->view('index', null, TRUE);

    }

}

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Beyond_mcp {

function __construct() {

$this->EE =& get_instance();

// $this->EE->load('view');

}

// admin.php?D=cp&C=addons_modules&M=show_module_cp&module=beyond&method=

function index() {

return $this->EE->load->view('index', null, TRUE);

}

載入自定義 javascript

// This will load from the current package's javascript director:
// /third_party/my_package/javascript/my_file.js
$this->EE->cp->load_package_js('my_file');

// This will load from the current package's javascript director:

// /third_party/my_package/javascript/my_file.js

$this->EE->cp->load_package_js('my_file');

mod.module_name.php
language/english/module_name_lang.php

Language 檔案定義 $lang 語系變數：

語系中 module_name_module_name 和 module_name_module_description 會出現在 MCP 的安裝 modules 列表上

$lang = array(

    "beyond_module_name"          => 'Beyond Module',
    "beyond_module_description"   => '...', 

);

$lang = array(

"beyond_module_name" => 'Beyond Module',

"beyond_module_description" => '...',

);

To Enable Mysql General Log

Log — Tags: MySQL — Posted by Starck on October 17, 2013

Edit my.cnf:

general_log=1
general_log_file=/path/mysql.log

1 2	general_log=1 general_log_file=/path/mysql.log

You can also rename the general query log file at runtime by disabling the log:

SET GLOBAL general_log = 'OFF';

With the log disabled, rename the log file externally; for example, from the command line. Then enable the log again:

SET GLOBAL general_log = 'ON';

How to recursively give directories or files access permissions?

Log — Tags: chmod, command, find, Linux — Posted by Starck on October 8, 2013

To recursively give directories read & execute privileges:

find /path/to/base/dir -type d -exec chmod 755 {} +

To recursively give files read privileges:

find /path/to/base/dir -type f -exec chmod 644 {} +

Or, if there are many objects to process:

chmod 755 $(find /path/to/base/dir -type d)

chmod 644 $(find /path/to/base/dir -type f)

Or, to reduce chmod spawning:

find /path/to/base/dir -type d -print0 | xargs -0 chmod 755

find /path/to/base/dir -type f -print0 | xargs -0 chmod 644

Function.bind

Coding, Log — Tags: javascript — Posted by Starck on October 4, 2013

你可以利用 function.bind 來改變呼叫函式的對象(this): JS Bin

try starck.callBySelf(); or starck.callByWindow(); in console.

function.bind

For a given function, creates a bound function that has the same body as the original function. In the bound function, the this object resolves to the passed in object. The bound function has the specified initial parameters.

function.bind(thisArg[,arg1[,arg2[,argN]]])

Reference

Callback 的應用: JS Bin try starck.say('hi')

CentOS – Linode Longview is not synchronize with your server

Log — Tags: CentOS, Linode — Posted by Starck on August 26, 2013

If you got a warning message from linode :

Your system’s clock is fast. Please ensure that ntp is installed and running.

How to solve the problem?

1. Change Time Zone (TZ)

$ sudo cp /usr/share/zoneinfo/Asia/Taipei /etc/localtime

$ sudo vim /etc/sysconfig/clock

change Etc/UTC to Asia/Taipei or yourself

2. Install NTP

$ sudo yum install ntp
$ sudo service ntpd start
$ sudo chkconfig ntpd on

$ sudo yum install ntp

$ sudo service ntpd start

$ sudo chkconfig ntpd on

$ sudo vim /etc/ntp/step-tickers:

0.pool.ntp.org
1.pool.ntp.org
2.pool.ntp.org
3.pool.ntp.org

0.pool.ntp.org

1.pool.ntp.org

2.pool.ntp.org

3.pool.ntp.org

$ sudo service ntpd restart

Done!
