报错信息：
证书已过期，或者已经无效。
虽然提示是证书问题，但是也还有可能是因为日期原因，因为日起原因变相的导致证书被变得不合格了
### 先看date
!(data/attachment/forum/202303/23/162829ys3mm4homlogk11g.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/300 "image.png")

所以需要修改下时间
`yum -y install ntpdate`
`ntpdate cn.pool.ntp.org`
ntp服务器有很多，如果这个有问题，可自行百度一个替换网址即可，详细操作日志如下
```bash
# yum -y install ntpdate
