生成符合chrome要求的自簽名HTTPS證書

按照文章給Nginx配置一個自簽名的SSL證書中給出的代碼生成自簽名證書后，發現使用chrome瀏覽器訪問會報 Invalid self signed SSL cert - “Subject Alternative Name Missing” 的錯誤，原因是 "沒有備份的主題名稱"，因而需要在生成的證書中加入備份的主題名稱，於是基於liaoxuefeng老師的代碼稍微修改了一下，使其能生成包含備份主題名稱的證書了。代碼如下：

#!/bin/bash

# create self-signed server certificate:

read -p "Enter your domain [www.example.com]: " DOMAIN

echo "Create server key..."

openssl genrsa -des3 -out $DOMAIN.key 1024

echo "Create server certificate signing request..."

SUBJECT="/C=US/ST=Mars/L=iTranswarp/O=iTranswarp/OU=iTranswarp/CN=$DOMAIN"

openssl req -new -subj $SUBJECT -key $DOMAIN.key -out $DOMAIN.csr

echo "Remove password..."

mv $DOMAIN.key $DOMAIN.origin.key
openssl rsa -in $DOMAIN.origin.key -out $DOMAIN.key

echo "Sign SSL certificate..."

echo "Gen subject ext file..."
echo "keyUsage = nonRepudiation, digitalSignature, keyEncipherment
extendedKeyUsage = serverAuth, clientAuth
subjectAltName=@SubjectAlternativeName

[ SubjectAlternativeName ]
IP.1 = $DOMAIN" > $DOMAIN.ext

openssl x509 -req -days 3650 -in $DOMAIN.csr -signkey $DOMAIN.key -out $DOMAIN.crt -extfile $DOMAIN.ext

echo "TODO:"
echo "Copy $DOMAIN.crt to /etc/nginx/ssl/$DOMAIN.crt"
echo "Copy $DOMAIN.key to /etc/nginx/ssl/$DOMAIN.key"
echo "Add configuration in nginx:"
echo "server {"
echo "    ..."
echo "    listen 443 ssl;"
echo "    ssl_certificate     /etc/nginx/ssl/$DOMAIN.crt;"
echo "    ssl_certificate_key /etc/nginx/ssl/$DOMAIN.key;"
echo "}"
