mv cfssl_linux-amd64 cfssl

chmod +x cfssl-certinfo cfssljson cfssl
cfssl print-defaults config > ca-config.json
cfssl print-defaults csr > ca-csr.json

ca-config.json

{
    "signing": {
        "default": {
            "expiry": "87600h"
        },
        "profiles": {
            "server": {
                "expiry": "87600h",
                "usages": [
                    "signing",
                    "key encipherment",
                    "server auth"
                ]
            },
            "client": {
                "expiry": "87600h",
                "usages": [
                    "signing",
                    "key encipherment",
                    "client auth"
                ]
            }
        }
    }
}

ca-csr.json

{
    "CN": "example.net",
    "key": {
        "algo": "rsa",
        "size": 2048
    },
    "names": [
        {
            "C": "CN",
            "L": "SC",
            "ST": "Chengdu",
            "OU": "PE"
        }
    ]
}

生成CA证书和私钥.

./cfssl gencert -initca ca-csr.json | ./cfssljson -bare ca -

ca-config.json  ca.csr  ca-csr.json  ca-key.pem  ca.pem  cfssl  cfssl-certinfo  cfssljson

签发Server证书

./cfssl print-defaults csr > fullchain-csr.json

cat fullchain-csr.json
{
    "CN": "Server",
    "hosts": [
        "172.16.0.72"
    ],
    "key": {
        "algo": "ecdsa",
        "size": 256
    },
    "names": [
        {
         "C": "CN",
         "L": "SC",
         "ST": "Chengdu",
         "OU": "PE"
        }
    ]
}

生成服务端证书和私钥

./cfssl gencert -ca=ca.pem -ca-key=ca-key.pem -config=ca-config.json -profile=server fullchain-csr.json | ./cfssljson -bare fullchain

fullchain.csr  fullchain-csr.json  fullchain-key.pem  fullchain.pem

生成客客户端证书和私钥

 ./cfssl print-defaults csr > private.json
./cfssl gencert -ca=ca.pem -ca-key=ca-key.pem -config=ca-config.json -profile=client private.json | ./cfssljson -bare privkey
