记录一次误删除localhost.key和localhost.cet恢复

先贴命令

openssl req -x509 -out localhost.crt -keyout localhost.key \
  -newkey rsa:2048 -nodes -sha256 \
  -subj '/CN=localhost' -extensions EXT -config <( \
   printf "[dn]\nCN=localhost\n[req]\ndistinguished_name = dn\n[EXT]\nsubjectAltName=DNS:localhost\nkeyUsage=digitalSignature\nextendedKeyUsage=serverAuth")

然后把文件复制到相关目录即可

localhost.key在/etc/pki/tls/private/目录下

localhost.crt在/etc/pki/tls/certs/目录下

就可以了
