1 2 3

mkdir -pv /etc/pki/CA/{certs,crl,newcerts,private}   touch /etc/pki/CA/{serial,index.txt}

指定证书编号

?

1 2	cd /etc/pki/CA echo 01 >> serial

生成CA私钥

?

1	umask 077; openssl genrsa -out /etc/pki/CA/private/cakey.pem 4096

根据私钥生成CA证书

?

1	openssl req -new -x509 -key /etc/pki/CA/private/cakey.pem -out /etc/pki/CA/cacert.pem -days 3650

 

生成服务端证书
