【已解答】php7.4安装不成功，说证书有问题

提示--2025-07-15 16:16:28-- https://na1-node.bt.cn/install/4/old/php.shResolving na1-node.bt.cn (na1-node.bt.cn)... 128.1.164.196Connecting to na1-node.bt.cn (na1-node.bt.cn)|128.1.164.196|:443... connected.ERROR: cannot verify na1-node.bt.cn's certificate, issued by ‘CN=sslTrus (RSA) OV CA,O=sslTrus,C=CN’:Unable to locally verify the issuer's authority.To connect to na1-node.bt.cn insecurely, use `--no-check-certificate'.

更新系统根证书：

1. curl --etag-compare etag.txt --etag-save etag.txt --remote-name https://curl.se/ca/cacert.pem

复制代码

如果提示不支持 etag，则使用这条命令

1. curl --remote-name --time-cond cacert.pem https://curl.se/ca/cacert.pem

复制代码

如上面的解决方法不行的话，则参考当前解决方法：

1. echo "check_certificate = off" >> /etc/wgetrc

复制代码
