*安装php的mongo扩展

wget 'https://codeload.github.com/mongodb/mongo-php-driver/zip/master' -O /usr/local/src/mong_php.zip

cd /usr/local/src/

unzip mong_php.zip

cd mongo-php-driver-master/

/usr/local/php/bin/phpize

./configure --with-php-config=/usr/local/php/bin/php-config

make && make install

vi /usr/local/php/etc/php.ini //增加 extension = mongo.so

/usr/local/php/bin/php –m

重启apache，重新加载php 

lnmp则重启php-fpm

*测试mongo扩展

vi /usr/local/apache2/htdocs/1.php //增加

<?php

// 连接到mongodb

$m = new MongoClient();

echo "Connection to database successfully";

// 选择一个数据库

$db = $m->mydb;

echo "Database mydb selected";

?>

curl  localhost/1.php
