# Running docker-compose under systemd
1.  Place the systemd unit files in /etc/systemd/system
2.  Create each docker-compose in a subdir under /usr/local/docker/
3.  Enable the cleanup service:
```
systemctl enable docker-compose.timer
```
4.  For each of your docker-compose applications, enable and start it.  For example, to start the app in /usr/local/docker/traefik:
```
systemctl enable docker-compose@traefik
systemctl start docker-compose@traefik
```

Move your site to an entirely new domain with .htaccess

RewriteEngine On

RewriteCond %{HTTP_HOST} kitibz [NC]
RewriteCond %{HTTP_HOST} www\.kitibz\.com [NC]
RewriteRule ^.*$ https://www.kitnaib.co.uk%{REQUEST_URI} [R=301,L]

Force both HTTPS and WWW. prefix using .htaccess even if behind an ELB or load balancer and if using a CDN

# force https
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteCond %{SERVER_PORT} 80
# Optional: exclude certain conditions, e.g. local host:
RewriteCond %{HTTP_HOST} !^localhost [NC]
RewriteRule ^.*$ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

# now force www
RewriteCond %{HTTP_HOST} !=""
RewriteCond %{HTTP_HOST} !^www\. [NC]
# let's allow our CDN to not follow these rules too:

# let's allow sitemap.xml to be hit without redirection:

allow from kitnaibdev.co.uk

Add and force trailing slash to URLs with htaccess

This two liner will perform a redirect to any folder to prevent 404s and duplicate content.

e.g.

http://www.yobbo.wang/?p=88
用户身份验证：Token与Session
开放接口Api服务其实就是客户端与服务端无状态交互的一种形式，
这有点类似REST(Representational State Transfer)风格。
普通网站应用一般使用session进行登录用户信息的存储和验证（有状态），
而开放接口服务/REST资源请求则使用Token进行登录用户信息的验证（无状态）。
Token更像是一个精简版的session。Session主要用于保持会话信息，会在客户端保存一份cookie来保持用户会话有效性，
而Token则只用于登录用户的身份鉴权。所以在移动端使用Token会比使用Session更加简易并且有更高的安全性，
同时也更加符合RESTful中无状态的定义。

Token交互流程
客户端通过登录请求提交用户名和密码，服务端验证通过后生成一个Token与该用户进行关联，并将Token返回给客户端。
客户端在接下来的请求中都会携带Token，服务端通过解析Token检查登录状态。
当用户退出登录、其他终端登录同一账号、长时间未进行操作时Token会失效，这时用户需要重新登录。

Token生成原理
服务端生成的Token一般为随机的非重复字符串，根据应用对安全性的不同要求，会将其添加时间戳
（通过时间判断Token是否被盗用）或url签名（通过请求地址判断Token是否被盗用）后加密进行传输。
一般Token内容包含有：用户名/appid，密码/appsecret, 授权url，用户自定义token(用户自定义签名)，时间戳，
有效期时长(秒), 系统签名(sign)等。

Api接口服务调用流程：
服务端access_token可以存储在session或者redis等内存数据库中，键名(key)为user_id,键值为access_token。
客户端获得access_token后，保存到file或redis等内存数据库中。不推荐保存到session或数据库中，
保存到session数据容易丢失，保存到数据库因为涉及IO读写，性能较低。

对于敏感的api接口，需使用https协议
http叫超文本传输协议，使用TCP端口80，默认情况下数据是明文传送的，数据可以通过抓包工具捕获到，因此在interner上，有些比较重要的站点的http服务器需要使用PKI（公钥基础结构）技术来对数据加密！这也就是https了；
https叫安全的超文本传输协议，使用TCP端口443，他的数据会用PKI中的公钥进行加密，这样抓包工具捕获到的数据包也没有办法看包中的内容，因为他没有密钥，当然篡改也就没有什么意义了，安全性大大提高，
要解密数据的话就要用到PKI中的私钥。所以一些安全性比较高的网站如：网上银行，电子商务网站都需要用https访问！

微信的access_token的有效期目前为2个小时，需定时刷新，重复获取将导致上次获取的access_token失效。

Token Auth的优点

Token机制相对于Cookie机制又有什么好处呢？

1.支持跨域访问: Cookie是不允许垮域访问的，这一点对Token机制是不存在的，前提是传输的用户认证信息通过HTTP头传输.
2.无状态(也称：服务端可扩展行):Token机制在服务端不需要存储session信息，因为Token 自身包含了所有登录用户的信息，
只需要在客户端的cookie或本地介质存储状态信息.
3.更适用CDN: 可以通过内容分发网络请求你服务端的所有资料（如：javascript，HTML,图片等），
而你的服务端只要提供API即可.
4.去耦: 不需要绑定到一个特定的身份验证方案。Token可以在任何地方生成，只要在你的API被调用的时候，
你可以进行Token生成调用即可.
5.更适用于移动应用: 当你的客户端是一个原生平台（iOS, Android，Windows 8等）时，Cookie是不被支持的
（你需要通过Cookie容器进行处理），这时采用Token认证机制就会简单得多。
6.CSRF:因为不再依赖于Cookie，所以你就不需要考虑对CSRF（跨站请求伪造）的防范。
7.性能: 一次网络往返时间（通过数据库查询session信息）总比做一次HMACSHA256计算 的Token验证和解析要费时得多.
不需要为登录页面做特殊处理: 如果你使用Protractor 做功能测试的时候，不再需要为登录页面做特殊处理.
8.基于标准化:你的API可以采用标准化的 JSON Web Token (JWT). 这个标准已经存在多个后端库
（.NET, Ruby, Java,Python, PHP）和多家公司的支持（如：Firebase,Google, Microsoft）.
