centos7安装根证书

1. 将证书复制到 /etc/pki/ca-trust/source/anchors/ 文件夹，本文以mitmproxy的https证书为例

 cp /root/.mitmproxy/mitmproxy-ca-cert.cer /etc/pki/ca-trust/source/anchors/

2. 移动到将此证书软连接至 /etc/ssl/certs/文件夹中

ln -s /etc/pki/ca-trust/source/anchors/mitmproxy-ca-cert.cer  /etc/ssl/certs/mitmproxy-ca-cert.cer

3. 运行 update-ca-trust，更新系统的证书

update-ca-trust

Ubuntu

mitmproxy-ca-cert.cer  复制到 /usr/local/share/ca-certificates/，然后执行 update-ca-certificates 即可

sudo cp ca.crt /usr/local/share/ca-certificates/mitmproxy-ca-cert.cer 
sudo update-ca-certificates
