使用RSA密钥创建一个自签名的CA证书
[root@rhel ～]# openssl req -new -x509-days 3650-key /root/ca.key -out /root/ca.crt
Enter pass phrase for/root/ca.key: //输入密钥保护密码
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.
