wget -c https://pecl.php.net/get/mongodb-1.5.3.tgz
tar -zxvf mongodb-1.5.3.tgz

cd mongodb-1.5.3

./configure --with-php-config=/www/server/php/70/bin/php-config
make && make install

cd /www/server/php/72/lib/php/extensions 

ls  //查看no-debug

vim /www/server/php/70/etc/php.ini
extension = /www/server/php/70/lib/php/extensions/no-debug-non-zts-20151012/mongodb.so

上面一行的no-debug-xx 要根据ls查看到的填写
