查看证书文件缺失：
[root@localhost yum.repos.d]# ls -l /etc/pki/tls/certs/ca-bundle.crt
lrwxrwxrwx 1 root root 49  3月 14  2020 /etc/pki/tls/certs/ca-bundle.crt -> /etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem
[root@localhost yum.repos.d]# ls -l /etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem
ls: 无法访问 '/etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem': 没有那个文件或目录
 

解决办法：

重新生产证书文件

[root@localhost yum.repos.d]# mkdir -p /etc/pki/ca-trust/extracted/pem
[root@localhost yum.repos.d]# update-ca-trust
[root@localhost yum.repos.d]# ls -l /etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem
-r--r--r-- 1 root root 219744  2月  6 21:24 /etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem
