【cfssl自签证书】卧疾丰暇豫，翰墨时间作。这篇文章主要讲述cfssl自签证书相关的知识，希望能为你提供帮助。
cfssl是一个开源的证书管理工具，使用json文件生成证书，相比openssl更方便使用。
下载软件包

wget https://pkg.cfssl.org/R1.2/cfssl_linux-amd64
wget https://pkg.cfssl.org/R1.2/cfssljson_linux-amd64
wget https://pkg.cfssl.org/R1.2/cfssl-certinfo_linux-amd64
chmod +x cfssl_linux-amd64 cfssljson_linux-amd64 cfssl-certinfo_linux-amd64
mv cfssl_linux-amd64 /usr/local/bin/cfssl
mv cfssljson_linux-amd64 /usr/local/bin/cfssljson
mv cfssl-certinfo_linux-amd64 /usr/bin/cfssl-certinfo

获取默认设置

cfssl print-defaults config > ca-config.json
cfssl print-defaults csr > ca-csr.json

创建CA配置文件

cat > ca-config.json < < EOF

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

EOF

创建CA签名请求

cat > ca-csr.json < < EOF

"CA": "expiry": "87600h",
"CN": "etcd CA",
"key":
"algo": "rsa",
"size": 2048
,
"names": [

"C": "CN",
"L": "Beijing",
"ST": "Beijing"

]

EOF

生成CA和私钥

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

自签证书请求

cat > server-csr.json < < EOF

"CN": "etcd",
"hosts": [
"192.168.31.61",
"192.168.31.62",
"192.168.31.63"
],
