Self-Signed Certificate

1）windows/Linux 安装 OpenSSL

openssl genrsa -out ca/ca.key 4096

openssl req -x509 -new -nodes -sha512 -days 3650 
-subj "/C=CN/ST=Beijing/L=Beijing/O=devops/OU=Personal/CN=devops.com" 
-key ca.key 
-out ca.crt

openssl genrsa -out linux.devops.com.key 4096

openssl req -sha512 -new 
-subj "/C=CN/ST=Beijing/L=Beijing/O=devops/OU=Personal/CN=linux.devops.com" 
    -key linux.devops.com.key 
    -out linux.devops.com.csr

cat > v3.ext <<-EOF
authorityKeyIdentifier=keyid,issuer
basicConstraints=CA:FALSE
keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment
extendedKeyUsage = serverAuth
subjectAltName = @alt_names
[alt_names]
DNS.1=devops.com
DNS.2=devops
DNS.3=linux.devops.com
EOF

openssl x509 -req -sha512 -days 3650 
    -extfile v3.ext 
    -CA ca.crt -CAkey ca.key -CAcreateserial 
    -in linux.devops.com.csr 
    -out linux.devops.com.crt

2）嫌麻烦可以使用在线自签生成器
