2.安装拓展（以mongodb为例）
# pecl install mongodb
//编译的时候很可能会报错
error：Cannot find OpenSSL's <evp.h>
//解决办法
yum -y install openssl-devel openssl pkgconfig
最后在php.ini中添加一句
extension=mongodb.so
phpize安装拓展
//下载压缩包，解压，进入解压目录
# phpize //一定要在解压的目录下执行
# ./configure --with-php-config=php-config所在目录 //如果你有多个php版本
# make && make install
//最后在php.ini加上一句extension=***.so
