如何在Linux系统中安装根证书

系统：Centos、Ubuntu、AlmaLinux、Rocky 其他发行版请自行测试
我们在申请证书的时候如果有根证书就需要安装

ca_bundle.crt   根证书
certificate.crt  IP或域名证书
private.key    秘钥

下面根据根证书演示

Centos、AlmaLinux、Rocky安装根证书

将证书复制到 /etc/pki/ca-trust/source/anchors 文件夹

cp /root/ca_bundle.crt /etc/pki/ca-trust/source/anchors/

软连接证书到 /etc/ssl/certs/ 文件夹

ln -s /etc/pki/ca-trust/source/anchors/ca_bundle.crt  /etc/ssl/certs/ca_bundle.crt

更新系统证书

update-ca-trust

Ubuntu安装根证书

将证书复制到 /usr/local/share/ca-certificates 文件夹

sudo cp ca_bundle.crt /usr/local/share/ca-certificates/ca_bundle.crt

更新系统证书

sudo update-ca-certificates
