原来一开始查询不包含g2证书，update ca-certificates更新证书之后，执行grep "DigiCert Global Root" /etc/pki/tls/certs/ca-bundle.crt命令显示如下，麻烦确认一下，这样是不是就包含了g2证书 Issuer: C=US, O=DigiCert Inc, OU=www.digicert.com, CN=DigiCert Global Root CA         Subject: C=US, O=DigiCert Inc, OU=www.digicert.com, CN=DigiCert Global Root CA         Issuer: C=US, O=DigiCert Inc, OU=www.digicert.com, CN=DigiCert Global Root G2         Subject: C=US, O=DigiCert Inc, OU=www.digicert.com, CN=DigiCert Global Root G2         Issuer: C=US, O=DigiCert Inc, OU=www.digicert.com, CN=DigiCert Global Root G3         Subject: C=US, O=DigiCert Inc, OU=www.digicert.com, CN=DigiCert Global Root G3

你好，我们现在是使用的centos6.5,根据文档查询grep "DigiCert Global Root" /etc/pki/tls/certs/ca-bundle.crt显示 Issuer: C=US, O=DigiCert Inc, OU=www.digicert.com, CN=DigiCert Global Root CA Subject: C=US, O=DigiCert Inc, OU=www.digicert.com, CN=DigiCert Global Root CA 不包含g2根证书，由于操作系统版本比较老，下载出来的DigiCert Global Root G2根证书和原来根证书格式不同，我应该怎么操作添加g2证书呢？另外，这个添加g2证书影响需php或者nginx或者apache的配置吗，还用为修改那些设置吗？
