php升级到5.6后，fsockpen(‘ssl://www.baidu.com‘, 443, $errno, $errstr, 10);
爆出：
PHP Warning: fsockopen(): SSL operation failed with code 1. OpenSSL Error messages:
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate
获取 php加载的 openssl.pem文件路径：
php -r "print_r(openssl_get_cert_locations());"
Array ( [default_cert_file] => /usr/local/openssl/cert.pem [default_cert_file_env] => SSL_CERT_FILE [default_cert_dir] => /usr/local/openssl/certs [default_cert_dir_env] => SSL_CERT_DIR [default_private_dir] => /usr/local/openssl/private [default_default_cert_area] => /usr/local/openssl [ini_cafile] => [ini_capath] => )
ls /usr/local/openssl/cert.pem
根本没有这个文件，
做个软连接：
ln -s /usr/local/share/certs/ca-root-nss.crt /usr/local/openssl/cert.pem
OK.
FreeBSD php5.6 https fsockopen错误
