├── certs
├── crl

└── private4 directories

生成证书索引数据库文件

[root@centos8 CA]#touch /etc/pki/CA/index.txt

指定第一个颁发证书的序列号格式为01 02

[root@centos8 CA]#echo 01 > /etc/pki/CA/serial

生成CA私钥

[root@centos8 ~]#cd /etc/pki/CA
#安全考虑，在子shell中修改umask权限，不影响当前环境
[root@centos8 CA]#(umask 066;openssl genrsa -out private/cakey.pem 2048)

生成CA自签名证书

[root@centos8 CA]#openssl req -new -x509 -key /etc/pki/CA/private/cakey.pem -days 3650 -out /etc/pki/CA/cacert.pem
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) [XX]:CN
State or Province Name (full name) []:henan
Locality Name (eg, city) [Default City]:zhengzhou
Organization Name (eg, company) [Default Company Ltd]:magedu
Organizational Unit Name (eg, section) []:it
Common Name (eg, your name or your server's hostname) []:ca.magedu.org
Email Address []:admin@magedu.org

选项说明：
-new: 生成新证书签署请求
-x509: 专用于CA生成自签证书 x509证书格式
