<?php$connection = new MongoClient();$db = $connection->baz;// select a collection:$collection = $db->foobar;// or, directly selecting a database and collection:$collection = $connection->baz-

进入mongodb后:use log;var collNames = db.getCollectionNames();for (var i = 0; i < collNames.length; i++) { var coll = db.getCollection(collNames[i]); var stats = coll.stats(1024 * 1024); p...

1、建立一个新的mongodb库2、把当前的mongodb集合改为比如 log_data为log_data_2019040622303、把log_data_201904062230备份到新库中4、在获取数据的地方再连接新库的log_data_201904062230集合展示数据代码示例如下$where = array();if( $product_id ){ $w...

mongodump -h 127.0.0.1:12468 --collection log_qrcode_new_2015_05 --db log -o /backup/bullfrog/mongodb/log_qrcode_new_2015_05mongorestore --port 12468 -d log .

vi /etc/mongod.conf里面换了主库IP，然后登陆到mongodbuse local;show collections;OKNotice:如果mongodb无法启动，把mongod.conf里面的slave=true 改为slave=false就行

备份:mongodump -h 127.0.0.1:12001 --collection log_aliyun_operation --db log --gzip --archive=/home/20180407.archive还原:mongorestore  -h 127.0.0.1:12001--gzip --archive=/home/20180407.archive

3.0以上配置文件好像只能用空白那一般打空白配置失败或无效的话，可以复制下配置文件其它的空格。

# mongod.conf#where to loglogpath=/home/mongodb/log/mongod.loglogappend=true# fork and run in backgroundfork=trueport=10001dbpath=/home/mongodb/db# location of pidfilepid

import osimport timeimport datetimeoutput = os.popen("service mongod status").read()print( time.strftime( '%Y-%m-%d %H:%M:%S', time.localtime( time.time() ) ) )print( output )if "locked" in out...

主库配置：master=true从库配置:slave=oksouce=192.168.6.1:1001autoresync=true从库会自动同步数据

在mongo命令行里输入：db.log_ebay_orders_data.remove({eod_time:{$lt:1427126401}});

//连接mongdb$conn = new Mongo();$db = $conn->test; //数据库$collection = $db->table; //表?>其它连接办法//连接localhost:27017$conn = new Mongo();//连接远程主机默认端口$conn = new Mongo('test.com');

mysql: id = 123mongo: array('id'=>123)mysql: name link '%bar%'mongo: array('name' => new MongoRegex('/.*bar.*/i'))mysql: where id > 10mongo: array('id' => array('$gt' => 10))my

<?php$connection = new MongoClient();$collection = $connection->database->collectionName;echo $collection->count();?>

我这里下的是http://www.mongodb.org/downloads  2.2.0 Windows 32-bit把下载下来的文件解压到C:\mongodb然后新建如下目录:C:\mongodb\dataC:\mongodb\data\dbC:\mongodb\data\testC:\mongodb\log新建C:\mongodb\mongod

<?php$doc = array( "name" => "MongoDB", "type" => "database", "count" => 1, "info" => (object)array( "x" => 203, "y" => 102), "versions" => array("0.9.7", "0.9.8", "0.9.9"));

1、执行mongodb时报错：      ERROR: dbpath (/data/db/) does not exist.      Create this directory or give existing directory in --dbpath. 解决办法：     sudo mkdir -p /data/db      sudo chmod 777 -R /dat

1、find() 参数不能用空字符串，要用空的条件，请用array()2、find()里面，数据类型要注意，int和string 1和'1'不同的。

这里用到的$collection是这里生成的：http://blog.youkuaiyun.com/junqing124/article/details/8255049    //新增        $user = array('name' => 'caleng', 'email' => 'admin@admin.com');        $collection->insert($user)

MongoClient::find()返回一个MongoCursor对象，我们可以用foreach来获取里面的数据<?php$connection = new MongoClient();$collection = $connection->database->collectionName;$cursor = $collection->find();foreach ( $cursor

<?php$connection = new MongoClient(); // connects to localhost:27017$connection = new MongoClient( "mongodb://example.com" ); // connect to a remote host (default port: 27017)$connection = new Mong
