mongo的简单cfg文件配置
[root@mysqla ~]# more /etc/mongod.conf
port=27017
dbpath=/mysql/mogo/data
logpath=/var/log/mongodb.log
logappend=true
journal=tru
1、起mongo
[root@mysqla ~]# mongod -f /etc/mongod.conf –rest &
[1] 24909
[root@mysqla ~]# 2016-05-06T10:44:12.498+0800 I CONTROL [main] ** WARNING: –rest is specified without –httpinterface,
2016-05-06T10:44:12.498+0800 I CONTROL [main] ** enabling http interface
2、停mongo
[root@mysqla ~]# mongo
MongoDB shell version: 3.2.4
connecting to: test
Server has startup warnings:
2016-05-06T10:44:12.498+0800 I CONTROL [main] ** WARNING: –rest is specified without –httpinterface,
2016-05-06T10:44:12.498+0800 I CONTROL [main] ** enabling http interface
2016-05-06T10:44:16.794+0800 I CONTROL [initandlisten] ** WARNING: You are running this process as the root user, which is not recommended.
2016-05-06T10:44:16.794+0800 I CONTROL [initandlisten]
> db.shutdownServer();
shutdown command only works with the admin database; try ‘use admin’
> use admin
switched to db admin
> db.shutdownServer();
server should be down…
2016-05-06T10:45:06.337+0800 I NETWORK [thread1] trying reconnect to 127.0.0.1:27017 (127.0.0.1) failed
2016-05-06T10:45:06.338+0800 W NETWORK [thread1] Failed to connect to 127.0.0.1:27017, reason: errno:111 Connection refused
2016-05-06T10:45:06.338+0800 I NETWORK [thread1] reconnect 127.0.0.1:27017 (127.0.0.1) failed failed
> quit();
[1]+ Done mongod -f /etc/mongod.conf –rest
3、通过–rest参数打开调用web界面的功能
在命令行连接mongo时也会有提示
2016-05-06T10:44:12.498+0800 I CONTROL [main] ** enabling http interface
MongoDB 的 Web 界面访问端口比服务的端口多1000
MongoDB运行端口使用默认的27017，web端口号为28017，即地址为：http://ip地址:28017
例如:http://http://192.168.169.131:28017/
4、查看mongo里有哪些db
> show dbs
admin 0.000GB
local 0.000GB
test 1.042GB
5、查看某个db下状态信息
> use test
switched to db test
> db.stats();
{
“db” : “test”,//数据库名
“collections” : 19,//数据库里存在的集合数或者可以叫做表
“objects” : 12030224,//数据库里所有集合存放多少条数据
“avgObjSize” : 266.7630486348384,//每条数据的平均大小
“dataSize” : 3209219230,//所有数据总大小
“storageSize” : 968974336,
“numExtents” : 0,
“indexes” : 20,//索引数
“indexSize” : 149827584,//索引大小
“ok” : 1
}
这上面还有其他信息是没有的，相关信息，可能需要参考mongo官方文档
6、查看某个db下的collections的信息
> show collections;
BrandFormMap
brand
brand_info
foo
member
member1
member3
org
pos_info
restaurants
store_info
store_info_20160419
table_name
test
test.user
testTag
user
voucherCode
voucher_code
> db.getCollectionNames()
[
“BrandFormMap”,
“brand”,
“brand_info”,
“foo”,
“member”,
“member1”,
“member3”,
“org”,
“pos_info”,
“restaurants”,
“store_info”,
“store_info_20160419”,
“table_name”,
“test”,
“test.user”,
“testTag”,
“user”,
“voucherCode”,
“voucher_code”
]
7、查看某个collections的具体信息，输出如下:
> db.foo.stats();
