1. 安装mongo的php插件
wget http://pecl.php.net/get/mongo-1.2.2.tgz //此php-driver包适用于php5.3;php5.4请选择1.2.12以上，1.2.12试用可以
tar xvf mongodb-mongo-php-driver-1.1.2-1-g5b2545e.tar.gz
tar xvf mongo-1.2.2.tgz
/usr/local/php/bin/phpize
./configure --enable-mongo=share --with-php-config=/usr/local/php/bin/php-config
make && make install
最后输出
Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/
2.编辑配置/etc/php.ini
extension_dir = "/usr/local/php/lib/php/extensions/no-debug-zts-20060613/"
extension = "mongo.so"
因为模块目录与mongo.so目录不一致，建立链接
ln -s /usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/mongo.so /usr/local/php/lib/php/extensions/no-debug-zts-20060613/mongo.so
3.检查是否安装成功
重启php，运行php -m| grep mongo 可以看到mongo插件已经被启用。
运行 php --ri mongo，输出以下代表可用。
