這篇文章我們講解 Kong 在 Centos 上的搭建，安裝 Cassandra 數據庫.

Kong簡介

Kong 是在客戶端和（微）服務間轉發API通信的API網關，通過插件擴展功能。Kong 有兩個主要組件：

Kong Server ：基于 nginx 的服務器，用來接收 API 請求。

Apache Cassandra ：用來存儲操作數據。

你可以通過增加更多 Kong Server 機器對 Kong 服務進行水平擴展，通過前置的負載均衡器向這些機器分發請求。根據文檔描述，兩個Cassandra節點就足以支撐絕大多數情況，但如果網絡非常擁擠，可以考慮適當增加更多節點。

Kong安裝

下載kong

https://getkong.org/install/centos/#packages

下載的文件 kong-0.7.0.el6.noarch.rpm

執行命令安裝
```
rpm -ivh kong-0.7.0.el6.noarch.rpm
```

$ sudo yum install epel-release
$ sudo yum install kong-0.7.0.*.noarch.rpm --nogpgcheck

</div> >如果出現 > 錯誤：Cannot retrieve metalink for repository: epel. Please verify its path and try again > 可以通過執行<font color=“red”>yum --disablerepo=epel -y update ca-certificates</font> 完美解決 :beer:

安裝 Cassandra

下載 Cassandra

wget: http://mirrors.hust.edu.cn/apache/cassandra/3.3/apache-cassandra-3.3-bin.tar.gz

安裝 Cassandra

tar -zxvf apache-cassandra-3.3-bin.tar.gz
cd bin/

執行cassandra -f 后臺啟動
./cassandra -f

> 在安裝cassandra要升級Python2.7.
> 執行./cqlsh 測試是否安裝成功
> 
  </pre> 
 
 
   
   Connected to Test Cluster at 127.0.0.1:9042.

  cqlsh> 
  

</div>
 恭喜你:beer: 安裝成功了 9042端口 > 執行./cqlsh 出現下面的錯誤，需要安裝python ssl模塊 > 
 
 
   
      [root@host-133-130-99-25 bin]# ./cqlsh

 <h4>Kong添加Rest Api </h4>

 <ol> 
  <li> <p>添加api</p>

   <div> 
    <div> 
     <pre class="brush:shell; toolbar: true; auto-links: false;">$ curl -i -X POST \
 --url http://localhost:8001/apis/ \
 --data 'name=mockbin' \ //自己的api name
 --data 'upstream_url=http://mockbin.com/' \ //API地址
 --data 'request_host=mockbin.com'  //API地址</pre> 
    </div>

   </div>
 <p>成功 顯示</p>

   <div> 
    <div> 
     <pre class="brush:shell; toolbar: true; auto-links: false;">HTTP/1.1 201 Created

Connection: keep-alive

{
  “request_host”: “mockbin.com”,
  “upstream_url”: “http://mockbin.com/“,
  “id”: “2eec1cb2-7093-411a-c14e-42e67142d2c4”,
  “created_at”: 1428456369000,
  “name”: “mockbin”
}</pre> 
    </div>

   </div>
 </li>

 </ol>

 <pre>使用`kong`作為代理請求API</pre> 
 <div> 
  <div> 
   <pre class="brush:shell; toolbar: true; auto-links: false;">$ curl -i -X GET \
    --url http://localhost:8000/ \
    --header 'Host: mockbin.com'</pre> 
  </div>

 </div>
 &lt;font color=“red”&gt;`:8000`&lt;/font&gt; 端口代理 
 <ol> 
  <li> <p>測試</p>
 <p> 訪問 http://localhost:8000/ 就可以訪問到自己的API了。 </p>
 </li>

  <li> <p>Nginx配置SSL</p>

   <div> 
    <div> 
     <pre class="brush:shell; toolbar: true; auto-links: false;">   ssl on;
ssl_certificate  /*.crt;
ssl_certificate_key /*.key;
ssl_session_timeout 5m;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers ALL:!ADH:!EXPORT56:-RC4+RSA:+HIGH:+MEDIUM:!EXP; ssl_prefer_server_ciphers on;</pre> 
    </div>

   </div>
 </li>

 </ol>

 <h4>Kong API添加插件 </h4>

 <ol> 
  <li> <p> 添加 key-auth 插件 配置apikey </p>
 <p> 執行命令: mockbin -&gt; api 名稱 </p>

   <div> 
    <div> 
     <pre class="brush:shell; toolbar: true; auto-links: false;">curl -i -X POST \
    --url http://localhost:8001/apis/mockbin/plugins/ \
    --data 'name=key-auth'</pre> 
    </div>

   </div>
 </li>

 </ol>

 <pre>添加成功顯示:</pre> 
 <div> 
  <div> 
   <pre class="brush:shell; toolbar: true; auto-links: false;"> HTTP/1.1 201 Created
    Date: Tue, 08 Mar 2016 08:07:51 GMT
    Content-Type: application/json; charset=utf-8
    Transfer-Encoding: chunked
    Connection: keep-alive
    Access-Control-Allow-Origin: *
    Server: kong/0.7.0

    {"api_id":"413fc8b3-4c45-43eb-a3c1-17f9325d5527","id":"4706cc84-    b97a-48c4-90eb-e8ec8491d3d7","created_at":  1457424471000,"enabled":true,"name":"key-auth","config":{"key_names":   ["apikey"],"hide_credentials"


?OK，成功添加`key-auth`插件



API 配置訪問權限
執行命令: username=Slj -> Slj用戶
```shell
 --接口添加用戶控制
 curl -i -X POST \
 --url http://localhost:8001/consumers/ \
 --data "username=Slj"</pre> 
</div>
</div>
Slj用戶配置apikey
 
 
curl -i -X POST \
 --url http://localhost:8001/consumers/Slj/key-auth/ \
 --data 'key=9eGpzqh4U3qMMuSk' 
</div>
:beer:第一個插件安裝成功了, 我們測試一下吧
 
 測試API 訪問權限
 在 Headers 中添加 apikey 值 
  
 apikey 是我們上面添加的值，:beer:我們愉快的獲得到了數據。 


改變一下apikey值，看看什么效果



:joy:出錯了，那么恭喜你，Kong的插件起效果了。</pre> </div>
