首先服务器需要已经安装了openssl支持，然后执行命令：

 

Generating a 4096 bit RSA private key

................................................................................                                                                                                                                                             ................................................................................                                                                                                                                                             ................++

.....................++

writing new private key to 'key.pem'

Enter PEM pass phrase:

Verifying - Enter PEM pass phrase:

-----

You are about to be asked to enter information that will be incorporated

into your certificate request.

What you are about to enter is what is called a Distinguished Name or a DN.

There are quite a few fields but you can leave some blank

For some fields there will be a default value,

If you enter '.', the field will be left blank.

-----

Country Name (2 letter code) [AU]:CN

State or Province Name (full name) [Some-State]:Beijing

Locality Name (eg, city) []:Beijing

Organization Name (eg, company) [Internet Widgits Pty Ltd]:Fesite Studio

Organizational Unit Name (eg, section) []:Fesite

Common Name (e.g. server FQDN or YOUR name) []:yoyo

Email Address []:8266@qq.com

 

这样就会在当前目录下面生成两个文件，一个是key.pem（密钥），一个是cert.pem（证书），放到需要的目录即可。
