版本：3.6.3
1. 部署MongoDB服务 192.168.4.50
创建服务工作目录
]# mkdir /usr/local/mongodb
]# cd /usr/local/mongodb/
]# mkdir etc
]# mkdir log
]# mkdir -p data/db
安装软件
]# tar -zxvf mongodb-linux-x86_64-rhel70-3.6.3.tgz
]# cd mongodb-linux-x86_64-rhel70-3.6.3/
]# cp -r bin /usr/local/mongodb/
编写配置文件
]# vim /usr/local/mongodb/etc/mongodb.conf
logpath=/usr/local/mongodb/log/mongodb.log
logappend=true
dbpath=/usr/local/mongodb/data/db
fork=true
:wq
启动服务
]# /usr/local/mongodb/bin/mongod -f /usr/local/mongodb/etc/mongodb.conf
bout to fork child process, waiting until server is ready for connections.
forked process: 18252
child process started successfully, parent exiting
]# alias startmdb=‘/usr/local/mongodb/bin/mongod -f /usr/local/mongodb/etc/mongodb.conf‘
查看服务信息
]# netstat -utnlp | grep :27017
]# ps -C mongod

停止服务
]# /usr/local/mongodb/bin/mongod -f /usr/local/mongodb/etc/mongodb.conf --shutdown
killing process with pid: 18252
]# alias stopmdb=‘/usr/local/mongodb/bin/mongod -f /usr/local/mongodb/etc/mongodb.conf --shutdown‘
使用命令别名启动服务
]# startmdb

show profile show most recent system.profile entries with time >= 1ms
show logs show the accessible logger names

exit quit the mongo shell
> exit
启动mongodb服务定义服务使用ip 地址及端口号
]# stopmdb
]# vim /usr/local/mongodb/etc/mongodb.conf
bind_ip=192.168.4.50
port=27050
:wq

tcp 0 0 192.168.4.50:27050 0.0.0.0:* LISTEN 18556/mongod
连接时指定指ip地址和端口号
]# /usr/local/mongodb/bin/mongo --host 192.168.4.50 --port 27050
> exit
2. MongoDB服务基本使用
2.1 常用管理命令
> show dbs
admin 0.000GB
local 0.000GB
> use gamedb(没有则直接创建）
switched to db gamedb
> db //查看当前库
gamedb
> db.t1.save({name:"bob",age:19,sex:"boy",school:"xxx"}) //插入数据
WriteResult({ "nInserted" : 1 })
> db.t1.save({class:"999"})
WriteResult({ "nInserted" : 1 })
> show tables
t1
> db.t1.find() //查看数据

2.3 数据导入导出
数据导出： 把集合的文档存储到系统文件里
创建存储文件的目录
]# mkdir /mdb
> db.t1.find() (gamedb库，t1表)
{ "_id" : ObjectId("5e3978812c1cf44a97db51ae"), "name" : "bob", "age" : 19 }
{ "_id" : ObjectId("5e3978842c1cf44a97db51af"), "name" : "tom", "age" : 20 }
导出为json格式
]# /usr/local/mongodb/bin/mongoexport

-d gamedb -c t1 --type=json > /mdb/gamedb_t1.json(必须有gamedb库，t1表）

数据导入： 把系统文件的内容存储到集合里
使用json文件导入数据 (库表不存在，则直接创建)
]# /usr/local/mongodb/bin/mongoimport
