這篇是自己使用 Namecheap Comodo PositiveSSL 的購買與安裝流程～～

專有名詞：
DV: Domain Validation
OV: Organization Validation
EV: Extended Validation

1. 確認網域資訊

在購買 SSL 之前，必須先擁有一個認證的網域。我們可以使用 whois 來查詢網域的申請資料。whois 查詢出來的資料，請確定 “Administrative Contact Email” 的電子信箱是正確的。因為 SSL 會以此信箱為對象寄發。

首先我們要先在CentOS 上面產生兩個檔案 server.key 跟 server.csr
# openssl req -new -newkey rsa:2048 -nodes -keyout server.key -out server.csr

Country Name (2 letter code) [AU]: TW
State or Province Name (full name) [Some-State]: Taiwan
Locality Name (eg, city) []: Taichung
Organization Name (eg, company) [Internet Widgits Pty Ltd]: NA
Organizational Unit Name (eg, section) []: NA
Common Name (eg, YOUR name) []: <your-domain> (這裡一定要輸入正確的網域)
Email Address []: (網域註冊的信箱)

Please enter the following 'extra' attributes to be sent with your certificate request
A challenge password []: (可不填)
An optional company name []: (可不填)

2.到 Namecheap 申請 Comodo PositiveSSL 認證
身請時 Namecheap 會要求你提供 CSR (Certificate signing request) ，請將先前產生的 server.csr 的內容全部貼上。

設定完成後，Namecheap 會寄發 whois 提供的電子信箱，裡面附著認證碼。唯有通過認證後，SSL 才會由 “Pending Request” 變更為 “Certificates"。

3. 收到認證檔後序處理：

你會從Comodo 收到 crt的認證檔如下:
yourdomain_com.crt
yourdomain_com.ca-bundle

接著在系統下組合:
# cat yourdomain_com.crt yourdomain_com.ca-bundle > mysite_com.crt

由於 comodo 寄出的認證都沒提供  root 憑證..所以這部份要自己加

# vi mysite_com.crt
在最後面加上 comodo 的根憑證:

4. 在Nginx 下設定 SSL
Example of an SSL configured Virtual Host for nginx

引用:

    
server {
    listen 443;
    server_name mysite.com;

    ssl on;
    ssl_certificate /etc/nginx/certs/mysite_com.crt;
    ssl_certificate_key /etc/nginx/certs/server.key;

    #enables all versions of TLS, but not SSLv2 or 3 which are weak and now deprecated.
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

    #Disables all weak ciphers
    ssl_ciphers "ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA256:ECDHE-RSA-AES256-SHA:ECDHE-RSA-AES128-SHA:DHE-RSA-AES256-SHA256:DHE-RSA-AES128-SHA256:DHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA:ECDHE-RSA-DES-CBC3-SHA:EDH-RSA-DES-CBC3-SHA:AES256-GCM-SHA384:AES128-GCM-SHA256:AES256-SHA256:AES128-SHA256:AES256-SHA:AES128-SHA:DES-CBC3-SHA:HIGH:!aNULL:!eNULL:!EXPORT:!DES:!MD5:!PSK:!RC4";

    ssl_prefer_server_ciphers on;
    }

最後將Nginx 重啟就可以看到SSL認證的網站囉～～

這時你也可以使用 command 指令check是否正常:
# openssl s_client -showcerts -connect www.adj.com.tw:443

如果最後出現 ok 的訊息...就代表沒問題了～
