加载pem或crt文件时PEM_read_bio_X509失败

Question

我编译安装nginx 1.4.4和openssl 1.0.1h，安装后生成.pem和.key文件并将它们放在conf目录下，当我想启动它时显示出错了。

nginx$ sbin/nginx
nginx: [emerg] PEM_read_bio_X509("/home/work/nginx/conf/33iq.crt") failed (SSL:)

它只能看到PEM_read_bio_X509失败但没有ssl错误信息，如何找出它有什么问题？

openssl x509 -in /home/work/nginx/conf/33iq.crt -inform PEM -text -noout
