首先找到要注册到的目录
find / -name cert8.db
可以找到一些目录
其中ect下的是nss目录
用户目录下的是firefox的目录
下一步，使用certutil注册证书根
注册到firefox，具体参数参照文章开头
certutil -A -d /home/用户名/.mozilla/firefox/*.default -A -t "CT,," -n mycertest（随便起个名） -i 证书路径.crt
注册到nss
把 /home/用户名/.mozilla/firefox/*.default 换成 /etc/pki/nssdb 即可
注意：目录都是定位到db的上一级，不是直接定位到*.db
