How to use mm-webreplay?

[dreamyouonly]

• What I finished
  I have finished these steps: "Build","Dependencies".
  And mm-webrecord is able to work, although it will meet SIGILL Error at times.
  Now I am trying to follow the steps of mm-webreplay.

• What the problem is
  I compiled the source code of nginx-quic and got a runnable program. And get the CA root certificate through the steps of readme. But I don't know how to let mahimahi know where my nginx and certificate are (if that is necessary).
  After input "the secret", it shows:

enter priavet_key password :
ALT NAME r1 ---sn-ni5een7e.gvt1.com
Generating a RSA private key
.............................++++++++++
writing new private key to '/tmp/private.0N9qEW'
Using configuration from /tmp/cacfg.pMzdmI
unable to load CA private key

Can you help me with this problem？thanks a lot.

the nginx-quic project is https://hg.nginx.org/nginx-quic

您好，我在打算使用mm-webreplay的时候遇到了一些问题。
当前阶段：
我已经完成了build和dependency的安装，并且能够执行mm-webrecod访问到bilibili。但是这里会经常遇到chrome的报错SIGILL，导致页面无法加载。
我暂时忽略了SIGILL的问题探究，想要尝试mm-webreplay

问题描述：
我在~/mynginx中通过源码编译得到了nginx-quic的可执行程序，并且启用了http-ssl-module等必需模块。另外也按照readme的步骤生成了ca.key.pem和ca.cert.pem，并放在了~/mynginx/conf/ssl目录下。在启动nginx时，加密的ca.key.pem无法访问，报错bad_password_read,所以我通过openssl rsa -in xxx -out yyy的命令得到了解密后的key文件并能够正常启动nginx。
现在，我转而在mahimahi目录下启动mm-webreplay test，并输入我的secret，报错如下：

mahimahi replay working_directory : /home/wjt/mahimahi
enter priavet_key password :
ALT NAME r1---sn-ni5een7e.gvt1.com

我怀疑我的证书和nginx并不能被mahimahi识别，因为我并没有进行做配置。但是这一步如何去做？或者我之前步骤中有什么不当之处？
请您指正，谢谢！
