2. Enter the domain name you want to apply for the certificate in the input box, click Create free SSL Certificate

3, if you are the application is a domain name directly enter your domain name can not add WWW system will automatically apply to you with www and without www domain name

4, after the domain name input system will prompt you to verify your domain name use, provides 3 kinds of authentication methods:

 a、Automatic FTP Verification （FTP账户验证，输入你对应网站的FTP信息，系统会上传一个文件到你的服务器上） b、Manual Verification （文件验证，系统会让你下载一个文件然后你把这个文件上传到你的服务上） c、Manual Verification （域名TXT记录解析认证，根据系统提示你的主机名和记录值做一个 TXT 记录）（a、b两种方法虽然相对简单，但是会提示你验证失败，道理大概和宝塔一样就是无法访问（至少我操作的时候是这样）推荐用c方法）
