生成 CA 签名的证书

提供者 netapp-ivanad 下载此页面的 PDF

SnapDrive for UNIX 守护进程服务要求您生成 CA 签名的证书,才能成功进行守护进程通信。您必须在 snapdrive.conf 文件中指定的路径处提供 CA 签名证书。

  • 您必须以 root 用户身份登录。

  • 您必须已在 snapdrive.conf 文件中设置以下参数,才能使用 HTTPS 进行通信:

    • use-https-to-sdU-daemon=on

    • contact-https-port-sdU-daemon = 4095

    • sdU-daemon-certificate-path=` /opt/NetApp/SnapDrive/SnapDrive.pem`

步骤
  1. 以 pem 格式生成新的未加密 RSA 私钥:

    ` * $ openssl genrsa -out privkey.pem 1024*`

    Generating RSA private key, 1024 bit long modulus
     ....................++++++ ....................................++++++
    e is 65537 (0x10001)
  2. 配置 ` /etc/ssl/openssl.cnf` 以创建 CA 私钥和证书 vi ` /etc/ssl/openssl.cnf` 。

  3. 使用 RSA 私钥创建未签名的证书:

    ` * $ openssl req -new -x509 -key privkey.pem -out cert.pem*`

    You are about to be asked to enter information that will be
    incorporated into your certificate request.
    What you are about to enter is what is called a Distinguished Name or
    a DN.
    There are quite a few fields but you can leave some blank For some
    fields there will be a default value, If you enter '.', the field
    will be left blank.
    -----
    Country Name (2 letter code) [XX]:NY
    State or Province Name (full name) []:Nebraska Locality Name (eg,
    city) [Default City]:Omaha Organization Name (eg, company) [Default
    Company Ltd]:abc.com Organizational Unit Name (eg, section) []:
    Common Name (eg, your name or your server's hostname) []:localhost
    Email Address []:abc@example.org
  4. 使用私钥和证书创建 CSR :

    ` * cat cert.pem privkey.pem | openssl x509 -x509 tor均衡 器 -signkey privkey.pem -out certreq.csd*`

    Getting request Private Key Generating certificate request
  5. 使用刚刚创建的 CSR 使用 CA 专用密钥对证书进行签名:

    ` * $ openssl ca -in certreq.csr -out newcert.pem*`

    Using configuration from /etc/pki/tls/openssl.cnf Check that the
    request matches the signature Signature ok Certificate Details:

                 stateOrProvinceName       = Nebraska
                 organizationName          = abc.com
                 commonName                = localhost
                 emailAddress              = abc@example.org

     Certificate is to be certified until May 16 06:02:51 2016 GMT (365
     days) Sign the certificate? [y/n]:y
    
    
     1 out of 1 certificate requests certified, commit? [y/n]y Write out
     database with 1 new entries Data Base Updated
  6. 安装 SSL 服务器要使用的签名证书和专用密钥。

    The newcert.pem is the certificate signed by your local CA that you can then use in an
    ssl server:
    ( openssl x509 -in newcert.pem; cat privkey.pem ) > server.pem
    ln -s server.pem `openssl x509 -hash -noout -in server.pem`.0 # dot-zero
    ( server.pem refers to location of https server certificate)
