MongoDB实用场景
- 产品用户访问日志，点击埋点统计信息
- 业务系统环境参数配置信息
- 业务系统运行时日志，如laravel.log，nginx.log
使用Homebrew在macoOS安装MongoDB PHP Driver
在macOS中，MongoDB 扩展已经从Homebrew仓库中移除，需要通过pecl安装此扩展。

install ok: channel://pecl.php.net/mongodb-1.5.4
Extension mongodb enabled in php.ini

在项目中，使用phpinfo() 查询PHP扩展安装位置。

Configuration File (php.ini) Path /usr/local/etc/php/7.2
Loaded Configuration File /usr/local/etc/php/7.2/php.ini
Scan this dir for additional .ini files /usr/local/etc/php/7.2/conf.d
Additional .ini files parsed /usr/local/etc/php/7.2/conf.d/ext-opcache.ini, /usr/local/etc/php/7.2/conf.d/php-memory-limits.ini

|
按照ext-opcache.ini配置，创建一个ext-mongodb.ini文件
|
1
|
touch /usr/local/etc/php/7.2/conf.d/ext-mongodb.ini
|
将mongodb.so扩展写入该文件
|

|
[mongodb]
extension=/usr/local/Cellar/php@7.2/7.2.19/pecl/20170718/mongodb.so
|
同时在php.ini中移除mongodb.so扩展
|
1
2
|
extension="mongodb.so" // remove
extension="php_mongodb.so" // remove
|
重启一下PHP
|
1
|
sudo brew service restart --all
|
查看是否安装成功
|
1
|
php -m|grep mongodb
|
在Laravel中使用MongoDB
使用Composer创建一个Laravel项目
|
1
|
composer create-project --prefer-dist laravel/laravel laravel-mongodb-exploer -vvv
|
成功后，再安装Laravel-MongoDB扩展
|
1
|
composer require jenssegers/mongodb -vvv
|
按照扩展文档说明，我们添加一个MongoDB数据库连接

//database.php
...
'mongodb' => [
'driver' => 'mongodb',
'host' => env('MONGODB_HOST', 'localhost'),
'port' => env('MONGODB_PORT', 27017),
'database' => env('MONGODB_DATABASE'),
'username' => env('MONGODB_USERNAME'),
'password' => env('MONGODB_PASSWORD'),
'options' => [
'database' => 'admin' // sets the authentication database required by mongo 3
]
],
...
//.env
...
MONGODB_HOST=127.0.0.1
MONGODB_PORT=27017
MONGODB_DATABASE=viewers
...
|
命令行创建MongoDB数据库
macOS中，在命令行执行mongo开启MongoDB Shell
|
1
|
./mongo
|
使用show dbs查看已有数据库
|

|
show dbs;
admin 0.000GB
config 0.000GB
local 0.000GB
viewers 0.000GB
|
如果没有发现viewers，则创建该数据库。注意只有viewers中存在collection时， 上面结果才会显示viewers
|
1
|
use viewers;
|
使用数据库后，需要创建colleciton
|
1
|
db.ad_clicks.insert({"ip":"201.35.63.14", "ad_index": 3, "created_at": "2019-06-10 11:34:12"})
|
使用find查询记录

> db.ad_clicks.find()
{ "_id" : ObjectId("5cf71b34e14620598643d23b"), "ip" : "201.34.46.3", "ad_index" : "2", "created_at" : "2019-06-05 11:34:53" }
{ "_id" : ObjectId("5cf71d3de14620598643d23d"), "ip" : "200.14.145.64", "ad_index" : 1, "created_at" : "2019-06-04 11:11:45" }
{ "_id" : ObjectId("5cf71d3ee14620598643d23e"), "ip" : "200.14.145.64", "ad_index" : 1, "created_at" : "2019-06-04 11:11:45" }
{ "_id" : ObjectId("5cf71d44e14620598643d23f"), "ip" : "200.14.145.64", "ad_index" : 1, "created_at" : "2019-06-04 11:11:45" }
{ "_id" : ObjectId("5cf71d45e14620598643d240"), "ip" : "200.14.145.64", "ad_index" : 1, "created_at" : "2019-06-04 12:34:12" }
{ "_id" : ObjectId("5cfe28823316506991c41786"), "ip" : "201.35.63.14", "ad_index" : 3, "created_at" : "2019-06-10 11:34:12" }
|
在Laravel DB中查询MongoDB
使用了Laravel-MongoDB扩展，可以基于Eloquent与Query Builder操作MySQL一样的数据php artisan thinker
查询ad_clicks集合所有记录
|
1
|
DB::connection('mongodb')->table('ad_clicks')->get()
|
查询单个记录
|
1
|
DB::connection('mongodb')->collection('ad_clicks')->find('5cf71b34e14620598643d23b')
|
修改某个记录
|
1
|
DB::connection('mongodb')->collection('ad_clicks')->where('_id', '5cf71b34e14620598643d23b')->update(['ad_index'=>2]);
|
在Laravel ORM中查询MongoDB
在项目中，创建一个Model
|
1
|
php artisan make:model Models/AdClick
|
修改继承父类和数据库连接，AdClick.php

use Jenssegers\Mongodb\Eloquent\Model;
class AdClick extends Model
{
protected $connection = 'mongodb';
/**
* The attributes that are mass assignable.
*
* @var array
*/
protected $fillable = [];
/**
* The attributes that aren't mass assignable.
*
* @var array
*/
protected $guarded = [];
}
|
继续在Thinker中，插入数据
|
1
|
App\Models\AdClick::create(['ip' => '31.42.4.14', 'ad_index' => 4, 'created_at' => '2019-06-10 18:10:01', 'ip2long' => ip2long('31.42.4.14')]);
|
统计访问数据
|
1
|
App\Models\AdClick::where('ip', '31.42.4.14')->count()
|
