前面有篇文章介绍了MongoDB安装使用：http://msiyuetian.blog.51cto.com/8637744/1720559
下面这篇文章主要来介绍PHP怎么来连接MongoDB，在进行试验之前先安装PHP，我这里是基于LAMP环境下做的测试。
1、下载安装php的mongo扩展
[[email protected] ~]# cd /usr/local/src/
[[email protected] src]# wget http://pecl.php.net/get/mongo-1.4.5.tgz -O mong_php.tar.gz
[[email protected] src]# tar -zxvf mong_php.tar.gz
[[email protected] src]# cd mongo-1.4.5/
[[email protected] mongo-1.4.5]# /usr/local/php/bin/phpize
|
Configuring for: PHP Api Version: 20090626 Zend Module Api No: 20090626 Zend Extension Api No: 220090626 |
注意：若这步报错缺少一些文件，说明是扩展包有问题，需重新到网上下载一个可用的扩展包。
[[email protected] mongo-1.4.5]# ./configure --with-php-config=/usr/local/php/bin/php-config
[[email protected] mongo-1.4.5]# make
[[email protected] mongo-1.4.5]# make install
| Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/ |
由上可看到生成的mongo.so文件
[[email protected] mongo-1.4.5]# ls /usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/
| mongo.so |
2、编辑配置文件
[[email protected] mongo-1.4.5]# vim /usr/local/php/etc/php.ini //最后一行添加
| extension = mongo.so |
[[email protected] mongo-1.4.5]# /usr/local/php/bin/php -m |grep mongo
| mongo |
由上可知已经成功加载了mongo扩展
重启Apache服务（若为LNMP，则重启php-fpm服务）
[[email protected] mongo-1.4.5]# /usr/local/apache2/bin/apachectl restart
3、测试
新建测试文件
[[email protected] mongo-1.4.5]# vim /usr/local/apache2/htdocs/mongotest.php
|
<?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"; ?> |
测试结果如下
[[email protected] mongo-1.4.5]# curl localhost/mongotest.php
| Connection to database successfullyDatabase mydb selected |
由上可知配置成功。
注意：若我们把 /usr/local/php/etc/php.ini 配置文件的 "extension = mongo.so" 这行注释掉，重启Apache服务后测试结果为500
[[email protected] mongo-1.4.5]# curl localhost/mongotest.php -I
