我尝试了两种不同的方法来安装mongodb php驱动程序。
服务器是Centos 6.6（32位），最初是一个6.5虚拟盒映像（更新后）现在称自己为6.6
错误似乎从这里开始：

我已经检查了其他（看似相关的）Stack帖子，例如MongoDB PHP driver can't installed Centos 6 cloud server - 但它似乎没有帮助或适用。 有任何想法吗？感谢。

您似乎没有为OpenSSL安装标头。
尝试yum install openssl-devel（如果不是root，则使用sudo）然后重新编译。

对于任何人来说命令 yum install openssl-devel 没有解决在centos实例中安装PHP56 Mongo驱动程序尝试使用/安装这些
sudo yum install php-pear
sudo yum install php56-devel
sudo yum install gcc
sudo yum install openssl-devel
sudo pecl install mongodb
