#先安装一个依赖库

yum -y install openldap-devel

wget https://pecl.php.net/get/mongodb-1.1.1.tgz

/home/server/php7/bin/phpize   #根据自己编译的PHP环境而定

./configure --with-php-config=/home/server/php7/bin/php-config

make && make install

#如果成功,生成一个mongodb.so扩展在lib/php/extensions/no-debug-non-zts-20151012/

extension=mongodb.so

註:

先前版本用的是mongo .so擴展,老的php-mongodb api

在PHP7已經不支援了,至少目前不支援。

最新支援PHP7的mongodb 編譯後僅支援新版API(mongodb > 2.6.X版本)
