第一步导入证书：

a、运行输入“mmc”

 b、在控制台中点击“文件”——>“添加/删除管理单元”，在弹出框中依次选择“证书”-“添加”-“”-“肯定”

上图点击“添加”弹出框选择“计算机帐户”，一直下一步到完成。

 

c、证书导入，“证书”右键 选择“全部任务”，点击“导入“。

 

 d、证书受权

 一、工具下载 安装winhttpcertcfg.msi 下载地址 https://www.microsoft.com/en-us/download/details.aspx?id=19801。

 二、到winhttpcertcfg安装目录运行以下命令提高帐户访问权限：WinHttpCertCfg.exe -g -c LOCAL_MACHINE\MY -s "证书名" -a  "NETWORK SERVICE"。

      说明：-s  证书名（如：www.xxxx.com） ；-a 受权用户

 三、若是你的IIS是7.0，须要设置网站应用池标识（如图）。

 

四、重启IIS
